En konkurrenskraftig strategi kan vara en avgörande faktor för ett företags framgång. En formell företagsstrategi ser till att både de som deltar i den strategiska planeringen och i genomförandet följer samma mål. Det riktas kritik mot hur företag använder sig av strategisk planering och den största utmaningen för företagen ligger i att implementera strategin i verksamheten. Ett problem som är kopplat till strategier är att organisationers sätt att skapa konkurrensfördelar förändras snabbt. Företagen måste på grund av detta skapa förutsättningar för en ständigt pågående strategisk dialog.Syftet är att undersöka hur små och medelstora företag (SMF) arbetar med den strategiska planeringen i verksamheten och hur de kontrollerar att de strategiska aktiviteterna verkar i linje med det långsiktiga målet. Syftet med studien är även att ta reda på vilka faktorer som bidrar till en lyckad strategisk planering och implementering hos SMF. För att besvara vårt syfte har en multipel fallstudie gjorts på två SMF i Sjuhäradsområdet. Personliga intervjuer har genomförts med personer från företagens ledningsgrupp och styrelse.SMF har gemensamma karaktärsdrag gentemot stora företag och följande områden har undersökts: omgivningsfaktorer, organisationsmiljö och ledningen. Storleken på företaget har en betydande roll när det kommer till hur stor påverkan omgivningen har på ett företag. SMF har mer begränsade resurser vilket bidrar till större osäkerhet i omgivningen och att hålla koll på bland annat andra konkurrenter. Organisationsstrukturen hos SMF kännetecknas av en platt struktur med få ledningsnivåer vilket bidrar till en hög flexibilitet och förmåga att anpassa sig till marknaden. De få ledningsnivåerna bidrar till att antalet mellanchefer är färre och kravet på Vd:ns ledningsexpertis ökar.The Closed-Loop Management System är en modell som föreslås användas vid strategisk planering hos företag. Modellen består av fem steg: utveckla strategin, översätta strategin, planera handlingar, kontrollera och lär samt testa och anpassa strategin. Modellen beskriver hur företag ska gå tillväga från att formulera och uttala strategin till att implementera och kommunicera den i verksamheten och har använts som underlag för att undersöka hur SMFs arbetar med strategisk planering och strategisk kontroll i praktiken. För att säkerställa att implementering av strategin blivit lyckad behöver företagen utföra strategisk kontroll. Ett sätt att utföra strategisk kontroll är genom att använda sig av integrerad prestationsmätning. Det innebär en balanserad styrning mellan finansiella och icke-finansiella mått där orsak- och verkansamband mellan de olika måtten kartläggs och har undersökts på företagen i studien.Slutsatser som kan dras av studien är att tre viktiga faktorer som bidrar till strategisk framgång i SMF är: inställningen hos de anställda, val av organisationsstruktur och tydlig kommunikation. För att genomföra den strategiska planeringen används ett metodiskt arbetssätt för att strukturera upp aktiviteter och delmål som finns för att uppnå det övergripande målet. Genom att bryta ned det övergripande målet i delmål och aktiviteter säkerställer företagen att de kortsiktiga handlingarna verkar i linje med den långsiktiga strategiska planen. Det är även viktigt för företagen att kontrollera och mäta dessa aktiviteter. Finansiella och icke-finansiella mått används för strategisk kontroll men studiens resultat visar att de finansiella måtten är dominerande. / A competitive strategy is essential for a corporate’s success in their industry. The challenge is not only to design the strategy; it is to spread it throughout the organization. An integrated measurement system refers to support and control the activities and goals that leads to strategic success. Thus, earlier studies have shown that integrated measurement systems have contributed to improve large enterprises’ performances when applied in their businesses. However, this study refers to the gap of research on the use of integrated measurement systems and its impact on small and medium-sized enterprises (SME). This study focusses on two Swedish SMEs and research what characterize their qualities that contributes to strategic success. The study will also focus on how the SMEs apply strategic planning and strategic control in their business’s.The study was based on previous studies in the context of strategy. The interviews were conducted on two Swedish SMEs, and the respondents were people that are a part of each company’s management team that possess both knowledge and insight to the company’s strategic work.Our findings suggest that factors contributing to strategic success in SME’s are: the communication approach, the attitude of the employees and the organizational structure. The strategic planning in SME wasn’t based on a specific model to support the strategic planning. However, they use a similar methodical approach to implement the activities in the strategic planning process. Finally, the study also shows that SMEs use integrated measurement in terms of financial and non-financial measurements, where the financial measurements had a greater impact on the SME business’s.

Study project (MBA)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: This assignment tries to provide insight into the reasons required for the formulation of sustainability performance indicators. It develops two sets of performance indicators for government and business respectively, to be used in an attempt to create a sustainable South Africa. It is approached in a very distinctive manner with two specific focus areas. Firstly, it examines the requirements of government, as this allows for the creation of a foundation upon which business can prosper, and examines the requirements with which to create this foundation. Secondly, once a sound foundation is laid, this paper examines the requirements of business that is believed to provide guidelines for shaping their sustainability. All this is done against a backdrop of the principles of good governance endorsed both internationally and in South Africa. / AFRIKAANSE OPSOMMING: Hierdie dokument probeer om lig te werp op die redes vir die formulering van prestasie aanwysers vir volhoubare ontwikkeling, en struktureer twee stelle aanwysers vir die regering en besighede, om hulle volhoubaarheid te ondersteun in Suid-Afrika. Daar is twee spesifieke fokusareas. Eerstens word verwys na die regering, en die vereistes waarop die fondasie gebou kan word waarop besighede kan floreer. Tweedens word gekyk na wat van besighede verlang word om verder volhoubare riglyne te omhels. Dit word alles gedoen teen die agtergrond van goeie regerings-en besigheidspraktyke, wat tans internasionaal en plaaslik beoefen word.

Thesis (MPA)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: The City of Cape Town has adopted the Balanced Scorecard as an organisational performance management system. Presently the system has only been implemented as a pilot project in the top three management levels of the organisation. The question then becomes one of how can individual obj ectives be aligned with the organisation's strategic objectives in this scenario. The purpose of this research is to propose a performance management model based on the Balanced Scorecard that aligns individual goals and objectives to those of the organisation. The study is in the form of a case study and specifically applies to the City of Cape Town Fire and Emergency Service. The foundation of the research is based on the creation of a sound theoretical base relating to organisational and individual performance management and the Balanced Scorecard. Once this understanding has been created the next step is to describe the development and implementation of the Balanced Scorecard project within the Cape Town context. This is the point of departure for the proposal of a Personal Scorecard performance management model. Data is to be collected via a process of semi-structured interviews and questionnaires. The information gained during the interviews created the framework within which the Personal Scorecard model was proposed. The questionnaire was used to pilot the main component of the Personal Scorecard model, namely the objective setting process. This created an opportunity to test the hypotheses made as the Personal Scorecard was developed. Once all of the components have been combined into the performance management model this research will be concluded with the presentation of recommendations relating to the knowledge gained during the model development process and alternative applications for the Personal Scorecard will be discussed. / AFRIKAANSE OPSOMMING: Die Stad Kaapstad het die "Balanced Scorecard" as 'n organisasie prestasie bestuursmeganisme aanvaar. Huidiglik is die meganisme net in die boonste drie bestuurs vlakke van die organisasie in gebruik geneem. Die kwessie wat geantwoord moet word is hoe individuele doelwitte met die van die organisasie versoen kan word in hierdie spesifieke scenario. Die doel van hierdie navorsing is om n prestasie bestuursmodel voor te stel wat op die "Balanced Scorecard" gebaseer is en individuele doelwitte met die van die organisasie versoen. Hierdie studie neem die vorm van 'n gevallestudie en is spesifiek gerig op die Stad Kaapstad Brand and Nooddienste. Die fondament van hierdie navorsing is gebaseer op die skepping van 'n sterk teoretiese basis met verband tot organisasie- en individuele prestasie bestuur en die "Balanced Scorecard". Die volgende stap is om die Balanced Scorecard ontwikkeling en uitvoering projek van die Stad te beskryf. Hierdie word die vertrekpunt vir die voorgestelde "Personal Scorecard" prestasie bestuursmodel. Data word versamel deur middel van semi-gestruktureerde onderhoude en vraelyste. Die inligting wat gedurende die onderhoude vesamel is het die raamwerk geskep waarin die "Personal Scorecard" voorgestel is. Die vraelyste is gebruik om die hoof bestanddeel van die "Personal Scorecard" model te loods namelik die doelwitstellendemeganisme. Hierdie proses het die geleentheid geskep om die hipotese wat gedurende die ontwikeling van die "Personal Scorecard" gemaak is, te toets. Na hierdie komponente gëintegreer is binne die prestasie bestuursmodel sal die navorsing afgesluit word met aanbevelings gebaseer op die kennis wat gedurende die modelontwikkeling proses versamel is en alternatiewe gebruike vir die "Personal Scorecard" sal bespreek word.

Thesis (MPA)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: The Department of Correctional Services (DCS) is security‐oriented environment with a constitutional mandate to enforce offenders’ sentences by the court in a humane and safe manner that leads to their rehabilitation. Performance by employees especially in a security‐oriented environment is inevitably important and therefore has to be properly managed. Performance appraisal is one area of performance management that reinforces good performance. This study is meant to achieve the following objectives: To review literature regarding optimal performance appraisal processes in the DCS ; To conduct an investigation into the perceptions of DCS employees on how performance appraisal is done in the department ; To develop recommendations on how to improve performance appraisal conduct in the department. A literature review is conducted to put into perspective an ideal performance appraisal. Following this, qualitative and quantitative case study design methods were used to investigate how performance appraisals are viewed. Research participants were randomly sampled from Goodwood Prison, including Bellville Community Corrections. Their perceptions of the current system were tested and they were also asked how they thought it could be improved. Their input was collected by means of questionnaires. Collected data is then analysed, conclusions drawn and recommendations made on how performance appraisal could be improved. This study afforded DCS members an opportunity to interact with the researcher, in terms of representing their perceptions performance appraisal in the department. A major finding in this study is that the majority (70%) of DCS employees were not happy with the way appraisal is conducted in the department. Major causes of dissatisfaction included favouritism or lack of fairness. This is followed by lack of training. Respondents placed emphasis on the requirements for improvement in both of these areas. Based on the conducted research, the thesis offers the following recommendations to the DCS, namely making spiritual care a major player in increasing fairness and in eliminating favouritism which derails satisfactory performance appraisal in the department. Training is suggested as another way that improve performance appraisal in the department. In conclusion performance appraisal should be treated as important and given the attention that it deserves by management. This will result in better performance by employees and the department itself and is of utmost importance in a security‐oriented environment. / AFRIKAANSE OPSOMMING: Die Departement van Korrektiewe Dienste (DKD) is sekuriteits‐en omgewingsgeörienteerd met ‘n konstitisionele mandaat om vonnisse van oortreders wat deur die hof opgelê is op ‘n veilige en menslike wyse toe te pas wat hul rehabilitasie tot gevolg hê. Produktiwiteit van werknemers is veral noodsaaklik en belangrik in ‘n sekuriteitsge‐orienteerde omgewing en moet dus gevolglik effektief bestuur word. Produktiwiteitsmeting is een fasset van produktiwiteitsbestuur wat goeie prestasie en hoër produktiwiteit bevorder. Die mikpunt van hierdie studie was om die volgende doelstellings te bereik: Om ‘n oorsig van die akademiese literatuur aangaande die optimale produktiwiteitsassesseringsprosesse in die DKD te bied ; Om die menings van DKD werknemers oor die proses van produktiwiteitsassessering in die DKD te ondersoek ; en Om voorstelle te ontwikkel vir die verbetering van produktiwiteitsassesseringspraktyke in die department. ‘n Oorsig van akademiese literatuur was gedoen om ‘n ideaal vir produktiwiteitsassessering in perspektief te plaas. Vervolgens is kwalitatiewe en kwantitatiewe ondersoekinstrumente toegepas in ‘n gevallestudie om die opvattings omtrent produktiwiteitsassessering te ondersoek. Goodwood gevangenis, en Bellville Gemeenskapsgevangenis was die bronne vir deelnemers aan die ondersoek . Hul opvattings oor die huidige struktuur was getoets, sowel as hul menings oor hoe dit verbeter kan word. Hul bydrae was verkry deur middel van ‘n vraelys. Die versamelde data was ge‐analiseer, afleidings is gemaak , menings was gevorm en voorstellings is gemaak oor hoe produktiwiteitsassessering verbeter kan word. Die ondersoek het ‘n geleentheid gebied vir interaksie tussen lede van die DKD en die ondersoekbeampte in terme van verteenwoordiging van lede in hul menings oor produktiwiteitsassessering in die department. ‘n Hoofstaande bevinding van die studie was dat ‘n oorweldigende meerderheid van werknemers van die DKD ongelukkig was met die wyse van produktiwiteitsassessering in die department. Hoofoorsake van ontevredenheid was voortrekkery en ongelyke behandeling. Dit was gevolg deur ‘n gebrek aan opleiding. Respondente het klem gelê op die vereistes vir verbetering in albei areas. Hierdie tesis maak die volgende voorstellings, gebaseer op die ondersoek wat geloods is: gee prioriteitsposisie aan geestelike sorg as ‘n groot faktor in die verhoging van gelyke behandeling en die uitskakeling van voortekkery as ‘n duiwel wat bevredigende prestasie‐ en produktiwiteitsassessering in die wiele ry binne die department. Opleiding was voorgestel as nog ‘n wyse waarop produktiwiteitsassessering in die department verbeter kan word. Ten laaste, produktiwiteitsassessering moet as belangrik behandel word en die goedverdiende aandag van bestuur geniet. Dit sal verhoogde produktiwiteit/werksprestasie by werknemers en die department self tot gevolg hê en is van uiterste belang in ‘n sekuriteitsge‐orienteerde omgewing.

Thesis (MBA (Business Management))--Stellenbosch University, 2008. / Traditionally, organisational performance and efficiency measurements have been focused on cost containment. Today, however, performance measurement systems of world-class organisations are tailored to drive manufacturing and service business excellence. Quality is crucial for gaining a competitive advantage internationally. Quality award programmes promote quality awareness, recognise the quality achievements of companies and provide a platform for sharing successful quality management initiatives. Quality award frameworks form the foundation for developing business excellence models. Business excellence models are based on the premise that customer satisfaction, people (employee) satisfaction and impact on society are all achieved through leadership driving the policy and strategy, the people management, resources and processes, leading ultimately to excellence in business results. In this paper five of the most prominent international business excellence models are discussed. The success stories of companies that have implemented these models are looked at and the South African Excellence Model is compared with these five international models. The aim of the study is to analyse the South African Business Excellence Model as compared to international models such as the Deming Prize, the MBNQA, the EFQM, the AQA and the SQA. Case studies of two companies, Combine Cargo and Daimler Chrysler, are analysed with the aim of determining the shortcomings of the SAEM and the effects of the SAEM on business practices. Conclusions are drawn based on the experiences of these businesses, in order to verify the shortcomings and the effects of the SAEM. Lastly, the reasons for the failure of the SAEF and the SAEM are investigated and recommendations and guidelines are given for the revival of the SAEM and the promotion of quality in South Africa.

Thesis (MBA (Graduate School of Business))--Stellenbosch University, 2008. / ENGLISH ABSTRACT: Globalisation, constant innovations and well-informed customers have made modern business environments dynamic and complex. Organisations, with their ever-changing business models, are striving to improve the quality of their products and services. Congruently, several management theories have evolved. Total Quality Management (TQM),Just in Time (JIT), Benchmarking, Lean Management, Balanced Scorecard and Six Sigma are some of the more well known. Each movement with its own life span, its share of popularity and level of acceptance has the same basic goal – improvement in quality by measuring performance. Recent years have seen an upsurge in the approaches and contributions to the field of performance measurement. Are these management theories just a flavour of the month or do they add value. The object of this study is to provide industry specific manufacturing business with a Manufacturing Performance Measurement Matrix Model, which can be used over time to measure improvement and serve as a basis for Knowledge Management. / AFRIKAANSE OPSOMMING: Globalisering, konstante inbring van veranderinge en goed ingeligte kliënte het die moderne besigheidsomgewing dinamies en kompleks gemaak. Organisasies, met hulle ewig veranderende besigheidsmodelle, streef daarna om die kwaliteit van hulle produkte en dienslewering te verbeter. Verskeie bestuursteorieë het as gevolg hiervan ontwikkel. Die mees bekende bestuursteorieë is onder andere: Total Quality Management (TQM), Just in Time (JIT), Benchmarking, Lean Management, Balanced Scorecard en Six Sigma. Elkeen van hierdie planne, met sy eie leeftyd, porsie van die gewildheid en vlak van aanvaarding, het dieselfde basiese doel – verbetering van kwaliteit deur die meet van prestasie. Onlangse jare het ‘n opvlam gesien in die benaderings en bydraes tot die veld van prestasiemeting. Is hierdie bestuursteorieë net ‘n nuutjie of is hulle waardevol vir die besigheidswêreld? Die doel van hierdie studie is om industrie spesifieke vervaardigingsbesighede met ‘n Vervaardigings Prestasiemetings Matriks Model te voorsien wat deur die verloop van tyd verbeterings kan meet en kan dien as ‘n basis vir die bestuur van kundigheid.

Thesis (MA)--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: Today’s competitive and dynamic business world, solicits ever higher levels of performance and productivity. At the core of this drive to higher performance is the enhancement and managing of employees’ performance through a Performance Management system. Performance Management however, is a very complex, multi-dimensional and integrated system with a number of interacting critical prerequisites. Even in ideal circumstances, these fundamental elements would, in all likelihood, not all be satisfied during the initial phases of implementing a Performance Management system. The concern existed, on the basis of the abovementioned probabilities, that the Performance Management system of the Children and Families Division (CAF) of the Department of Health and Human Services (DHHS) of Tasmania, Australia, was not enjoying optimal operational effectiveness. The aim of this study was to identify those factors in the system that are underdeveloped, possibly unsuccessfully implemented or in need of attention as they impact negatively on the effective running of the CAF’s Performance Management system. A suitable tool for this diagnostic purpose already exists in the form of the Performance Management Audit Questionnaire (PMAQ), developed by Spangenberg and Theron (1997). Through administering and analysing the PMAQ results, the CAF could obtain a clear indication of the system’s current effectiveness and would be able to identify where the problem areas are in order to refine the system for greater operational effectiveness. The results successfully identified the underdeveloped or absent areas of the organisation’s current Performance Management system. The results further found a clear difference between managerial and non-managerial perceptions of the effectiveness of the Performance Management system. The implications of these findings are discussed in terms of proposed remedial actions that could be implemented to address the problem areas. / AFRIKAANSE OPSOMMING: ‘n Konstante strewe na steeds hoër vlakke van prestasie en produktiwiteit is aan die orde van die dag in die huidige hoogs kompeterende en dinamiese besigheidswêreld. Die verbetering en bestuur van werknemers se prestasie deur middel van ‘n Prestasiebestuurstelsel, blyk ‘n sleutel te bied tot hierdie strewe na hoër prestasie. Prestasiebestuur is egter ‘n hoogs komplekse, multidimensionele en geintegreerde stelsel met ‘n aantal interverwante kritieke vereistes. Selfs onder ideale omstandighede, sou dit onwaarskynlik wees dat al hierdie fundamentele elemente aangespreek sou kon word gedurende die anvanklike fases van die implementering van ‘n Prestasiebestuurstelsel. In die lig van die bogenoemde waarskynlikhede, het daar spesifiek twyfel geheers oor die mate waartoe die Prestasiebestuurselsel van die ‘Children and Families’ (CAF) afdeling van die ‘Department of Health and Human Services (DHHS) in Tasmanië, Australie, optimale operasionele effektiwiteit weerspieël. Die doel van hierdie studie was om die faktore binne die stelsel te identifiseer wat onderskeidelik onderontwikkeld, onsuksesvol geimplementeer, of aandag benodig het ten einde hulle negatiewe impak op die effektiewe bedryf van die CAF se Prestasiebestuurstelsel aan te spreek. ‘n Geskikte hulpmiddel vir so ‘n diagnostiese doelwit het reeds bestaan in die vorm van die Performance Management Audit Questionnaire (PMAQ) wat deur Spangenberg en Theron (1997) ontwikkel is. Deur middel van die administrasie van die PMAQ en die analise van die resultate, sou die CAF ‘n duidelike aanduiding kon verkry van die stelsel se effektiwiteit en sou hulle die probleemareas kon identifiseer ten einde die stelsel tot groter operasionele effektiwiteit te verfyn. Die resultate het die leemtes en onder-ontwikkelde areas binne die organisasie se huidige Presasiebestuurselsel suksesvol geidentifiseer. Die resultate het verder gedui op ‘n duidelike verskil tussen die persepsies van bestuurders en nie-bestuurders oor die effektiwiteit van die Prestasiebestuurstelsel. Die implikasies van hierdie bevindings word ten slotte bespreek in terme van die voorgestelde remediëringsaksies wat geimplementeer sou kon word om die probleemareas aan te spreek.

Bakgrund: Prestationsmätning utgör ett grundfundament i ekonomistyrning och avser styra i riktning mot långsiktiga mål. Vidare bör prestationsmätningen vara sprungen ur såväl långsiktiga mål som strategier där det på koncernnivå är av vikt att kongruens råder mellan moder- och dotterbolag. Vid utformning av en standardiserad modell för prestationsmätning måste hänsyn tas till rådande organisationsstruktur och företagsunika förutsättningar. Representerade mätetal avser påvisa kritiska områden med förhoppning att vidareutveckla verksamheten. Problemdiskussion: Koncernen Emballator Plastics & Innovations utgör tillsammans med underliggande dotterbolag ett konglomerat med koncerngemensam lean-strategi. Koncernen erhåller på månadsbasis rapporter över dotterbolagens prestationsmätning vilka upprättats utan direktiv ifrån koncernen och därmed är av särskiljande karaktär. Ett behov har uppkommit att låta standardisera en modell för prestationsmätning som samtliga dotterbolag kan nyttja för att enklare kunna skapa en övergripande bild över dotterbolagens prestationer. Prestationsmätningsmodellen skall vara standardiserad men samtidigt inte förbise företagsspecifika förutsättningar detta för att tillföra nytta på såväl koncern- som dotterbolagsnivå. Syfte: Denna studie syftar att utveckla en standardiserad prestationsmätningsmodell till Emballator Plastics & Innovations, vilken tar hänsyn till koncernens konglomerat och lean-strategi. Utvecklad prestationsmätningsmodell ämnar skapa en övergripande bild samt tillföra nytta på såväl moder- som dotterbolagsnivå. Metod: Detta är en fallstudie med kvalitativ ansats. Tillvägagångssätt för analys har varit av deduktiv karaktär där den teoretiska grunden i huvudsak baseras på vetenskapliga artiklar. Insamling av empiriskt material har erhållits via dokument samt intervjuer av övervägande semistrukturerad karaktär. Respondenter innefattar verkställande direktörer på koncern- liksom dotterbolagsnivå. Slutsats: Kongruens mellan långsiktiga mål och strategier på Emballator Plastics & Innovations och underliggande dotterbolag har identifierats. Med anledning av identifierad kongruens har förutsättningar funnits att utforma en standardiserad prestationsmätningsmodell. Väsentliga mätetal har utkristalliseras i avseende att skapa en övergripande bild över dotterbolagens prestationer. Modellens utformning främjar konglomeratet. / Background: Performance measurement is a basic foundation in financial management and control, where the intention is to fulfill long-term objectives. Performance measurement should therefore be developed with consideration to long-term objectives and strategies. Consequently, there is a need of congruence between the parent- and subsidiary level. When developing a standardized model for performance measurement, the current organizational structure and conglomerate needs to be considered. Represented key performance measurement aim to demonstrate the critical areas with the intention to influence improvements within the corporation. Problematization: Emballator Plastics & Innovations, is a composition of underlying subsidiaries, characterized of conglomerate and lean-strategy. The corporation receives monthly reports of the subsidiaries’ performance measurement, which have been constructed without directives from the corporation and this resulted in reports of distinctive character. Consequently, the need of a standardized model of performance measurement with the aim to easier receive a comprehensive picture of the subsidiaries' overall performance has arisen. However, the remaining problem is how to develop a standardized performance measurement model, which is beneficial for both parent- and subsidiary level, without ignoring the conglomerate. Purpose: This study aims to develop a standardized performance measurement model to Emballator Plastics & Innovations, where the corporations conglomerate and lean- strategy is taken into account. The developed performance measurement model intends to create an overall picture and bring benefits to both parent- and subsidiary level. Methodology: This is a case study with a qualitative approach. Procedure for analysis has been of deductive character where the theory is mainly based on scientific articles. Collection of empirical data has been obtained through documents and interviews with semi-structured character. Respondents include chief executives at parent- and subsidiary level. Conclusion: Congruence between long-term objectives and strategies at Emballator Plastics & Innovations and subsidiaries has been identified. Regarding to the identified congruence, potentials to develop a standardized performance measurement model have been secured. Significant key performance measurements have been detected, this with aim to receive an overall picture of the subsidiaries' performance. Finally, the design of the model has been designed in consideration of the conglomerate.

Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The aims of this thesis are to identify all possible modes of operaton for a multi-stage axial flow compressor; then to characterise the performance, attempt to numerically model operation, and determine the main flow field features for each mode. Four quadrant axial flow compressor operation occurs when the direction of flow through the compressor or the sign of the pressure difference across the compressor reverses, or any combination of these. Depending on the direction of rotation of the compressor, six modes of operation are possible in the four quadrants of the performance map. The rotor rotates in the design direction for three modes, and in the opposite direction for the other three. The stationary-rotor pressure characteristic is S-shaped and passes through the second and fourth quadrants. A three-stage axial flow compressor operating in the incompressible flow regime was used for the experimental investigation. Flow through the compressor was reversed or augmented by means of an auxiliary axial flow fan. Compressor performance was measured by means of static pressure tappings, a turbine anemometer calibrated to measure forward and reversed volumetric flow and a load cell for torque measurement. The inter-blade row flow fields were measured with pneumatic probes and 50 μm cylindrical hot film probes. Three dimensional single blade-passage Navier-Stokes simulations were performed using the Numeca FineTurbo package. Steady state simulations used a mixing plane approach. A nonlinear harmonic approximation was used for time-unsteady simulations. Unstalled first quadrant operation was unremarkable, and good agreement was obtained between experimental and numerical data. A single stall cell was detected experimentally during stalled operation, which was not modelled numerically. In the fourth quadrant for positive rotation, (windmilling), the compressor acts as an inefficient turbine. Flow separates from the pressure surface of the blade, rendering the steady-state mixing plane approach unsuitable. The performance characteristic curves for second quadrant for positive rotation, are discontinuous with those of first quadrant operation. The temperature rise in the working fluid is significantly higher than at design point. Periodic flow structures occurring across two blade passages were detected at all flow coefficients investigated, invalidating numerical modelling assumptions. Better agreement was obtained between experimental and numerical data from a case found in literature. If the compressor operates as a compressor in reverse (third quadrant operation), significant separation occurs on the pressure surface of all blades, and flow conditions resemble severe first quadrant stall. Separation becomes less severe at larger flow rates, allowing numerical simulation, though this is sensitive to the initial flow field. In the the part of the second quadrant, where the compressor rotates in reverse, it operates as a turbine. The blade angles and the direction of curvature match the flow angles and turning well, leading to high turbine efficiencies. Numerical simulations yielded good agreement with measured results, but were again sensitive to the initial flow field. Fourth quadrant operation with negative rotation occurs when flow is forced through the compressor in the design direction. Large separation bubbles are attached to the pressure surfaces of rotor and stator blades, so virtually all throughflow occurs near the hub and casing / AFRIKAANSE OPSOMMING: Die doelwitte van hierdie tesis is om al die moontlike werkmodusse vir ’n bestaande multi-stadium aksiaalvloei kompressor uit te ken; om dan die gedrag te gekarakteriseer, ’n poging aan te wend om die werking numeries te modelleer, en die belangrikste vloeiveldkenmerke vir elke modus te bepaal. Vier-kwadrant aksiaalvloei kompressor werking vind plaas as die rigting van die vloei deur die kompressor, of die teken van die drukverskil oor die kompressor omkeer, of enige kombinasie daarvan. Afhangende van die rigting van rotasie van die kompressor is ses operasionele modusse moontlik in die vier kwadrante van die kompressorkaart. Die rotor draai in die ontwerprigting vir drie van die modes, en in die teenoorgestelde rigting vir die ander drie. Die stilstaande-rotor drukkarakteristiek is S-vormig gaan deur die tweede en vierde kwadrante. ’n Drie-stadium onsamedrukbare vloei aksiaalvloei kompressor is vir die eksperimentele ondersoek gebruik. Vloei deur die kompressor is omgekeer of aangehelp deur middel van ’n aksiaalvloei hulpwaaier. Kompressor werking is gemeet deur middel van statiese druk meetpunte in die omhulsel, ’n turbine anemometer wat gekalibreer is om vorentoe en omgekeerde volumetriese vloei te meet, en ’n lassel vir wringmoment meting. Interlemryvloeivelde is opgemeet met pneumatiese sensors en 50-μm silindriese warm film sensors. Drie-dimensionele Navier-Stokes simulasies is uitgevoer vir ’n enkele lem van elke lemry, met behulp van die Numeca FineTurbo sagtewarepakket. ’n Mengvlakbenadering is gebruik vir bestendige toestand simulasies, terwyl ’n nie-linere harmoniese benadering gebruik is vir die tyd-afhanklike simulasies. Ongestaakte eerste kwadrant werking was alledaags, en goeie ooreenkoms is gevind tussen die eksperimentele en numeriese data. ’n Enkele staak-sel is eksperimenteel ontdek tydens gestaakte werking. Gestaakte werking is nie numeries gemodelleer nie. In die vierde kwadrant vir positiewe rotasie, (”windmeulwerking”), werk die kompressor as ’n ondoeltreffende turbine. Vloei-wegbrekinging op die lem drukoppervlaktes maak die bestendige toestand mengvlakbenadering ongeskik. In die kenlyne vir tweede kwadrant positiewe rotasie, is daar ’n diskontinu¨ıteit in die prestasie karakteristiekkrommes vir die eerste en tweede kwadrant werking. Die temperatuurstyging in die werk- vloeistof is beduidend ho¨er as as by die ontwerppunt. Periodiese vloeistrukture wat oor twee lemme plaasvind is gevind by alle vloei ko¨effisi¨ente wat ondersoek is, en dit maak die numeriese modellering aannames ongeldig. Beter ooreenkoms tussen die eksperimentele en numeriese data iss verkry met ’n geval wat uit die literatuur gevind is. Indien die kompressor werk as ’n kompressor in omgekeerde (derde kwadrant weking), vind beduidende wegbreking op die drukoppervlak van al die lemme plaas, wat lyk soos ernstige gestaakte eerste kwadrant werking. Die vloeiskeiding raak minder ernstig by ’n groter vloeitempo, wat numeriese nabootsing toelaat, maar die nabootsings is sensitief vir die aanvanklike vloeiveld. In die tweede kwadrant, by omgekeerde rotasie, werk die kompressor as ’n turbine. Die lemhoeke en die rigting van lemkromming stem ooreen met die vloeihoeke en verwringing, wat lei tot ho¨er turbine doeltreffendheid. Numeriese nabootsings stem goed ooreen met gemete resultate, maar is weereens sensitief vir die keuse van die aanvanklike vloeiveld. Vierde kwadrant werking met negatiewe rotasie vind plaas wanneer die lug gedwing word om deur die kompressor in die ontwerprigting te vloei. Groot skeidingborrels sit vas aan die drukoppervlaktes van alle lemme, sodat meeste deurvloei naby die naaf en die omhulsel plaas vind.

In this era of globalisation and fierce competition amongst businesses, there is a need to improve advanced operations management philosophies such as just-in-time (JIT) manufacturing to enhance business performance. Literature review shows that there is no mechanism so far to identify key JIT drivers relevant to a given organisation and its production processes, and their impact on enterprise performance. The research carried out here therefore involved the development of a generic performance measurement model to identify and capture the influence of JIT practices on enterprise performance. A conceptual performance measurement model, which was designed based on comprehensive literature review and informal interviews/discussions with both academic researchers and industry practitioners describes the link between JIT drivers (Xi) and measurable performance (Y). This mathematically determined model is aimed at assisting managers in the systematic identification of the influence of key JIT drivers on enterprise performance using a multidimensional tool such as the extended balanced scorecard. The case study approach was selected as the most suitable methodology for testing and validating the conceptual model in JIT enabled production plant and was applied to the production process of Denso Manufacturing (UK) Ltd., a global automotive component manufacturer. A novel eight-step implementation procedure was designed to collect data, which were analysed and validated by design of experiments, linear mathematical modelling, computer based dynamic simulation and analytic hierarchy process tool. The performance measurement model was then successfully applied to a non-automotive component production plant (Risane Ltd.). In conclusion, the performance measurement model can now be suitably applied to JIT enabled manufacturing environments using relevant organisation specific JIT drivers and key performance indicators to optimise system performance. The contribution to knowledge is an innovative, user friendly, robust and multidimensional performance measurement model enabling industry practitioners to optimise JIT processes with substantial performance enhancement. The model could also be applied by future researchers to other operations management philosophies and industries, and at a higher level could be developed into a self-optimising software package, which will enable rapid determination of the key control parameters needed to optimise process performance just in time.
