Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: An efficient container shipping industry is something every country strives toward. Continuous improvement in this industry is of utmost importance in order to grow a country’s economy. One of the objectives of this research study is to determine the inefficiencies that exist within the South African container shipping industry. A lot of these inefficiencies cannot be eliminated by a single organisation, but require the cooperation of all the parties in a supply chain. Currently there is not enough interaction between the organisations in the supply chain apart from limited contact with direct customers and suppliers. The aim of the performance measurement system is to drive organisations throughout the supply chain to focus on the areas that require the most improvement. If inefficiencies are identified, the parties concerned should jointly come up with action plans to address these inefficiencies. This research study will focus mostly on the Cape Town region. The performance measurement system (PMS) developed in this study can be used to improve supply chain efficiency. Existing PMSs were researched in order to develop a system that is applicable to the container industry. Research of the industry was done with the aid of questionnaires, interviews, surveys and a focus group. The benefits of such a system should be carefully explained to representatives of the organisations in the industry to attract their participation. The success of the system is highly dependent on how well the parties in the supply chain participate, as it is only then that the efficiency of a supply chain can be measured. Management representatives were asked to indicate which key performance indicators they are measuring. This information was used as a basis for the study. There are various parties that are currently busy with similar studies, which emphasises the increased need for a supply chain PMS in the container shipping industry. Two case studies were identified that will benefit from a PMS. BMW’s manufacturing plant in Rosslyn and the fruit export industry in the Cape Town region were used as examples of integrated supply chains. The PMS can be easily adapted in order to apply it to other corridors or commodities. / AFRIKAANSE OPSOMMING: ‘n Doeltreffende houer verskepingsindustrie is iets waarna elke land streef. Konstante verbeterings in die industrie is baie belangrik vir ‘n land se ekonomie. Een van die doelwitte van hierdie navorsingsprojek is om te bepaal wat die ondoeltreffendhede in die houer verskepingsindustrie is. Baie van hierdie ondoeltreffendhede kan nie deur een organisasie opgelos of geïlimineer word nie. Dit moet deur die hele voorsieningsketting gesamentlik gedoen word. Daar is tans te min samewerking tussen organisasies in die voorsieningsketting. In die meeste gevalle werk organisasies slegs met hulle onmiddelike kliënte en verskaffers. ‘n Voorsieningsketting meting-stelsel sal verseker dat daar op die regte aspekte gefokus word. As ‘n ondoeltreffendheid geïdentifiseer word, is dit die verantwoordelikheid van die hele voorsieningsketting om te verseker dat die ondoeltreffendheid geïlimineer word. Dit sal beslis samewerking bevorder. Die navorsingsprojek fokus meestal op Kaapstad. Bestaande meting-stelsels was geondersoek om ‘n stelsel te ontwikkel wat van toepassing is op die houer verskepingsindustrie. Navorsing was gedoen deur middel van vraelyste, onderhoude, opnames en ‘n fokusgroep. Die doel van die meting-stelsel is om organisasies regdeur die voorsieningsketting te dryf om te fokus op die areas wat die meeste verbetering benodig. Die voordele van die stelsel moet noukeurig aan die bestuursverteenwoordigers van die organisasies in die voorsieningsketting verduidelik word sodat hulle sal deelneem aan die inisiatief. Die sukses van die meting-stelsel hang af van hoeveel organisasies sal deelneem. Die doeltreffendheid van ‘n voorsieningsketting sal eers werklik gemeet kan word as daar ‘n redelike groot belangstelling vanaf die industrie is. Bestuursverteenwoordigers was gevra om aan te dui watter prestasie-aanwysers hulle tans meet. Hierdie inligting was gebruik as ‘n basis vir die studie. Daar is tans verskeie partye wat besig is met soortgelyke navorsing. Dit beklemtoon die feit dat ‘n voorsieningsketting meting-stelsel werklik nodig is vir die houer verskepingsindustrie. Twee gevalle studies was geïdentifeseer dat hulle sal voordeel trek uit die implementering van ‘n voorsieningsketting meting-stelsel. BMW se Rosslyn voorsieningsketting en die vrugte uitvoer industrie in Kaapstad was gebruik as voorbeelde van geïntegreerde voorsieningskettings. Die meting-stelsels kan maklik aangepas word vir ander kommoditeite.

Thesis (MComm (Industrial Psychology))--University of Stellenbosch, 2006. / The leadership-for-performance framework designed by Spangenberg and Theron (2004) aspires to explicate the structural relationships existing between leader competency potential, leadership competencies, leadership outcomes and the dimensions of organizational unit performance. The Performance Index (PI) and Leadership Behaviour Inventory (LBI) comprise the leadership-forperformance range of measures. The PI was developed as a comprehensive criterion measure of unit performance for which the unit leader could be held responsible. The basic PI structural model has been developed to explain the manner in which the various latent leadership dimensions measured by the LBI affect the eight unit performance latent variables that are assessed by the PI. Although preliminary research suggests the basic PI structural model could be refined, continued research in this regard can only be justified if the basic PI measurement model is shown to be measurement invariant across independent samples from the target population. As part of ongoing research of the leadership-for-performance range of measures, this crossvalidation study investigated the extent to which the PI measurement model may be considered measurement invariant across two independent samples from the same population. Two samples were collected through non-probability sampling procedures and included 277 and 375 complete cases after imputation by matching. Item analysis and dimensionality analysis were performed on each of the PI sub-scales prior to the formation of item parcels. No items were excluded based on item- and dimensionality analysis results. Two composite indicator variables (item parcels) were created from the items of each sub-scale and were treated as continuous variables in the subsequent statistical analyses. Structural equation modelling, using robust maximum likelihood estimation, was used to perform a confirmatory first-order factor analysis on the item parcels for each sample. The measurement model was fitted to both samples independently and close fit for each sample was established. The measurement model was cross-validated using a progressive series of measurement invariance tests. Results indicated the PI measurement model did not display full measurement invariance across the two samples although it did cross-validate successfully under the configural invariance condition. Statistically significant non-equivalence was found to exist in both the measurement error variances and the factor covariances (p<0,05), although the p<0,05 critical value was only narrowly surpassed in both cases. The measurement model did, however, display metric invariance across the samples as no significant differences were found between the factor loadings, suggesting the content of each item is perceived and interpreted in a similar manner across samples from the target population. When considered in combination, these results may be viewed as quite satisfactory as they indicate that themeasurement model does not appear to vary greatly when fitted to data from the two samples. As this study has established at least metric invariance of the PI, it therefore provides some basis of confidence for proceeding with subsequent research aimed at establishing the structural invariance of the basic PI structural model and eventually research that links the leadership behaviour to work unit performance as measured by the PI. Limitations of this study are discussed.

Assignment (MA)--University of Stellenbosch, 2002 / ENGLISH ABSTRACT: The responsibility for the performance of any organisational unit ultimately lies with the leadership of the unit. Given this perceived pivotal role of leadership in work unit performance, the ultimate objective is to capture the nature of the presumed relationship between leadership and unit performance in a comprehensive structural model. To validate such a leadership model, however, requires an explanation of the manner in which the unit performance dimensions affect each other. Spangenberg and Theron (2002b) developed a generic, standardized unit performance measure (PI) that encompasses all the unit performance dimensions for which the unit leader could be held responsible. The objective of this paper is to investigate the internal structure of the PI in order to establish the inter-relationships between the eight unit performance latent variables. The PI consists of 56 questions covering eight dimensions. The validation sample consisted of 304 completed PI questionnaires. However, after imputation 273 cases with observations on all 56 items remained in the validation sample. Item analysis and dimensionality analysis was performed on each of the sub-scales using SPSS. Thereafter, confirmatory factor analysis was performed on the reduced data set using LISREL. The results indicated satisfactory factor loadings on the measurement model. Acceptable model fit was achieved for the measurement model. Subsequently, the structural model was tested using LISREL. The results provided statistics of good fit. Only four hypotheses failed to be corroborated in this study. Conclusions were drawn from the results obtained and suggestions for further research are made. / AFRIKAANSE OPSOMMING: Die prestasie van enige organisatoriese werkeenheid is die uiteindelike verantwoordelikheid van die leierskap van die eenheid. Gegewe hierdie waargenome sleutelrol van leierskap in werkeenheidprestasie, is die uiteindelike doelwit om die aard van die veronderstelde verwantskap tussen leierskap en eenheidprestasie in 'n omvattende strukturele model vas te lê. Die validering van so 'n leierskapmodel vereis egter 'n uiteensetting van die wyse waarop die eenheidprestasie-dimensies mekaar onderling beïnvloed. Spangenberg en Theron (2002b) het 'n generiese, gestandaardiseerde eenheidprestasie-meetinstrument (PI) ontwikkel wat al die eenheidprestasie-dimensies insluit waarvoor die leier van die eenheid verantwoordelik gehou kan word. Die doel van hierdie studie is om ondersoek in te stel na die interne struktuur van die PI ten einde die inter-verwantskappe tussen die agt eenheidprestasie latente veranderlikes vas te stel. Die PI bestaan uit 56 vrae wat die agt dimensies dek. Die validasiesteekproef bestaan uit 304 voltooide PI vraelyste. Na vervanging van ontbrekende waardes is die validasiesteekproef egter gereduseer tot 273 gevalle met waarnemings op al 56 items. Item-ontleding en dimensieanalise is op elk van die sub-skale met behulp van SPSS gedoen. Daaropvolgend is bevestigende faktor-analise op die verkorte datastel gedoen met behulp van LISREL. Die passingstatistieke het hier aanvaarbare resultate opgelewer. Vervolgens is die strukturele model met behulp van LISRELgetoets. Die resultate het hier bevredigende passingstatistieke gelewer. Daar kon vir slegs vier hipoteses nie steun gevind word in die studie nie. Op grond van die resultate is daar tot bepaalde gevolgtrekkings gekom en daar word aanbevelings vir verdere navorsing gemaak.
