Castillo Valera, Danilo, Villanueva Rodo, Alexis, Román Velásquez, Anthony Carlos, Pool Córdova, Harold Alfredo 14 December 2020 (has links)
En la actualidad es muy común ver empresas del sector industrial de alimentos y bebidas que cuentan con un área que se dedica a dirigir y ejecutar proyectos que generen valor para los accionistas, sin embargo, son muy pocas las organizaciones y contratistas que establecen una metodología adecuada que garantice el cumplimiento de los objetivos de cada uno de los proyectos sin ocasionar sobrecostos, entregas fuera de tiempo, insatisfacción de los interesados, entre otros aspectos. Por este motivo, el trabajo desarrollado a continuación tiene como finalidad evidenciar que la implementación de estándares y buenas prácticas recomendadas en la guía del PMBOK ®️ 6ta edición y la filosofía LEAN resultan beneficiosas, ya que pueden maximizar la rentabilidad de los proyectos, reducir costos por procesos que no agregan valor y mejorar la satisfacción de los interesados. Para esto, se presentará cómo se llevó a cabo la dirección de proyectos de automatización industrial “Industria 4.0” denominado “Implementación de una arquitectura convergente en ethernet en una planta de galletas” desarrollado por la empresa C&C Corporation para su cliente Galletas S.A. / Nowadays it is very common to see companies in the food and beverage industry that have an area that is dedicated to directing and executing projects that generate value for the shareholders. However, are very few organizations and contractors that stablish an adequate methodology that guarantees compliance with the objectives of each project without causing cost overruns, late deliveries, dissatisfaction of the interested parties, among other aspects. For this reason, work developed below has the application to demonstrate that the implementation of methods and good practices recommended in the PMBOK ®️ 6th edition guide and the LEAN philosophy has benefits, since you can maximize the profitability of projects, reduce costs for processes that do not add value and improve the satisfaction of the stakeholder. For this, it will be presented how the project management of industrial automatization “Industry 4.0” will be applied to the project “Implementation of an architecture convergent in ethernet in a Cookie plant” developed by the company C&C Corporation for its client Cookies S.A. / Trabajo de investigación

Challenges facing the project manager in planning and managing housing projects implemented by emerging contractors

De Wet, Phillippus Rudolph 12 1900 (has links)
Thesis (MBA (Business Management))--Stellenbosch University, 2008. / ENGLISH ABSTRACT: The project manager is facing many challenges when planning and managing an Emerging Contractor project. Constraints experienced by Emerging Contractors are exerting risks on the project and pose a challenge to the project manager to guide the project to successful completion. The constraints and risks experienced on an Emerging Contractor project are mostly related to inexperience and unproven track record. The Emerging Contractor has not been in business long enough to build trust relationships with suppliers. Suppliers are limiting their exposure to risk and are therefore not prepared to supply material in bulk or on credit to the Emerging Contractor. The term Emerging Contractor is a well-known term in the South African construction industry, but no clear definition exists of what criteria qualifies a contractor to be an Emerging Contractor. The assumption in the industry is that an Emerging Contractor is a construction business which is 100% controlled and managed by a black person. Emerging Contractors are conducting business at the bottom end of the market where there is no barrier to entry. This makes the competition very severe and the profit margins are very slim. Even though the contract values are low, the Emerging Contractor projects require a considerable amount of effort to manage and are therefore not cost effective for the experienced project manager. The constraints experienced by the Emerging Contractor can be addressed by co-opting experience to the project team to provide guidance, training and management assistance. The proposal will require additional funding, but after a few projects the Emerging Contractor would have built up a reputation as a successful contractor and will therefore be self sustaining. / AFRIKAANSE OPSOMMING: Die projekbestuurder moet baie uitdagings trotseer met die beplanning en bestuur van 'n Opkomende Kontrakteur. Beperkings wat deur die Opkomende Kontrakteur ervaar word lei tot 'n risiko vir die projek en bied dus 'n uitdaging aan die projekbestuurder om die projek te lei tot suksesvolle voltooiing. Die beperkings en risiko's wat deur 'n Opkomende Kontrakteur projek ervaar word, hou meerendeels verband met onervarendheid en gebrekkige ondervinding. Die Opkomende Kontrakteur is nog nie lank genoeg in die bedryf om vertrouensverhoudings met verskaffers op te gebou het nie. Verskaffers verskans dus hul blootstelling aan risiko en is dus nie bereid om materiaal in grootmaat of op krediet aan die Opkomende Kontrakteur te lewer nie. Die term "Emerging Contractor" is welbekend in die Suid-Afrikaanse konstruksiebedryf, maar 'n duidelike definisie kon nie gevind word wat die vereistes stel om as 'n Opkomende Kontrakteur te kwalifiseer nie. In die konstruksiebedryf word dit algemeen aanvaar dat 'n Opkomende Kontrakteur 'n konstruksie besigheid is wat 100% deur 'n swart persoon beheer en bestuur word. Opkomende Kontrakteurs ding mee op die intreevlak van die konstruksiebedryf waar daar weinig min versperring vir toetrede is. Dit maak die kompetisie baie straf en die winsmarge laag. Selfs al is die kontrakwaarde laag behels die Opkomende Kontrakteur projek buitengewone aandag en bestuur en is dit dan ook nie 'n koste effekiewe projek vir 'n ervare projekbestuurder nie. Die beperkings wat deur die Opkomende Kontrakteur ervaar word, kan aangespreek word deur ervare diensverskaffers na die projekspan te bring om leiding, opleiding en bestuurshulp te verskaf. Die voorgestelde projekbestuursplan benodig addisionele fondse, maar na 'n paar projekte het die kontrakteur vir hom/haar 'n reputasie opgebou wat hom/haar toelaat om volhoubaar te wees sonder die hulp van die diensverskaffers.

The role of civil engineering professionals within the housing environment in South Africa

Vosloo, Robert Nicolaas 03 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The development of mass housing is an excellent example of multi-disciplinary projects. Several housing projects have been unsuccessful due to a misunderstanding of the necessary collaboration and buy-in that are required from all parties concerned. The focus of this study is to identify the required skill sets and responsibilities of the Housing Project Manager in the Housing environment, and in turn, will support the development of the foundation of the civil engineering postgraduate curricula. Civil engineers are educated with a strong focus on technical subjects, but not much attention is paid to many of the less technical aspects as found in housing projects. Furthermore, the multi-disciplinary aspects of large projects do not receive sufficient attention in either the undergraduate or postgraduate curricula. Considering that many civil engineers become actively involved as managers of housing projects, this paper will present an investigation into the requirements of the curricula of a postgraduate qualification for civil engineers towards becoming managers in housing projects. The investigation will include aspects of multi-disciplinary coordination, the less technical aspects of housing development, but will not exclude a comprehension of technical involvement. In order to identify these skill sets and responsibilities several approaches were adopted. The approaches adopted in this dissertation include: (i) a comprehensive literature study regarding the housing environment and the position of the housing project manager, (ii) a review of several housing case studies with project management related problems, (iii) consulting with several housing management professionals from different sectors in the housing industry, and (iv) a review of existing formulations of the role and responsibilities of the housing project manager. The findings from this study provide evidence that civil engineers operating in the housing environment as project managers require additional education, due to the multi-disciplinary nature of housing projects. The main conclusion drawn from this study is that educating civil engineers towards the management of housing projects would contribute significantly to the housing environment through increasing productivity and quality, and can contribute to meet the housing targets of the government. / AFRIKAANSE OPSOMMING: Die ontwikkeling van massa behuising is 'n uitstekende voorbeeld van multidissiplinêre projekte. Verskeie behuisingsprojekte was al onsuksesvol as gevolg van 'n misverstand oor die nodige samewerking en bydraes wat vereis word van alle betrokke partye. Die fokus van hierdie studie is om die vaardighede en verantwoordelikhede van die behuisingsprojekbestuurder in die behuisingsomgewing te identifiseer. Hierdie kennis ondersteun die ontwikkeling van ʼn raamwerk vir ʼn nagraadse kurrikulum in behuisingsbestuur. Siviele ingenieurs is opgelei met 'n sterk fokus op tegniese vaardighede, maar relatief min aandag word geskenk aan minder tegniese aspekte soos gevind word in behuisingsprojekte. Verder, multidissiplinêre bestuursaspekte van groot projekte ontvang nie voldoende aandag in óf die voorgraadse óf nagraadse kurrikula nie. Wetende dat baie siviele ingenieurs aktief betrokke raak as bestuurders van behuisingsprojekte, ondersoek hierdie studie ʼn raamwerk vir ʼn nagraadse kwalifikasie vir siviele ingenieurs as bestuurders van behuisingsprojekte. Die ondersoek sluit in aspekte van die multidissiplinêre koördinasie asook minder tegniese aspekte van behuisingsontwikkeling, maar dit sluit nie 'n begrip van die tegniese betrokkenheid uit nie. Verskeie benaderings is toegepas om die vaardighede en verantwoordelikhede van behuisingsbestuurders te identifiseer. Die benaderings sluit in: (i) 'n omvattende literatuurstudie ten opsigte van behuising en die posisie van die behuisings-projekbestuurder, (ii) 'n oorsig van verskeie behuisings- gevallestudies met projekbestuur verwante probleme, (iii) raadpleging met verskeie professionele rolspelers van verskillende sektore in die behuisingbestuur omgewing, en (iv) 'n hersiening van bestaande beskrywings van die rol en verantwoordelikhede van die behuisings-projekbestuurder. Die bevindinge van hierdie studie verskaf bewyse dat siviele ingenieurs wat in die behuisingsbedryf as projekbestuurders optree, bykomende opleiding benodig as gevolg van die multidissiplinêre aard van projekte. Die belangrikste gevolgtrekking van hierdie studie is dat die opleiding van siviele ingenieurs in die bestuur van behuisingsprojekte ʼn aansienlike bydrae kan lewer tot behuising deur produktiwiteit en kwaliteit te verhoog. Dit kan bydra tot die bereiking van die regering se behuisingsdoelwitte.

The Zachman Framework applied to construction engineering risk management

03 July 2012 (has links)
M.Ing. / The research is based on the complexity of project management and risk management fields and how applying each field on its own can be problematic. This poses an everyday challenge to project managers when implemented simultaneously and such a problem predominantly exists in the engineering construction field.The challenge faced by project managers is approached throughout the research study by introducing a commonly used six order matrix framework with a high success rate in analysing and dissecting complex fields into small fragments. The framework is known as the Zachman Framework for Enterprise Architecture. However this is only done once a thorough literature review of both project and risk management as well as the limitations of the Zachman Framework have been well documented.Once the Zachman Framework for Construction adaptation is complete, it is then applied to an inner city construction case study. The results of the case study are used to determine if throughout the project lifecycle it has been possible to analyse and implement all project and risk management requirements simultaneously with little or no correction of project constraints.Using a developed integrated risk management tool which graphically tracks aggregate risk( s) in cost and time together with the Zachman Framework for Construction, the case study results reveal that it is possible to increase the ability to simultaneously manage risk and normal activities by concluding that the project constraints (i.e. cost) are accurately estimated and accomplished. In conclusion the research study,discussion and recommendations are made in order to implement all cells within the Zachman Framework for Construction therefore increasing the success of any project and risk management construction field.

Made available in DSpace on 2015-05-08T14:53:36Z (GMT). No. of bitstreams: 1 arquivototal.pdf: 3707850 bytes, checksum: ac7f3ffc992b6cdd3ee53234cc8f1db5 (MD5) Previous issue date: 2013-10-29 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In recent years much has been said about project management and how its contributions are important to the organizations to seek excellence and effectiveness in its undertakings. According to the Project Management Institute (PMI) , it is estimated that 25 % of global GDP are allocated to the projects, featuring increasingly the recognizing and the importance of this methodology and increasing its diffusion. Organizations that adopt this management methodology seek competitive advantages, new job opportunities and even to conquer other markets. But what it is perceived is that many organizations simply cannot meet deadlines in its planning and, in the presence of this scarcity, this dissertation presents the method of time planning on projects called Critical Chain Method, which is the application of the Constraints Theory in the environmental of projects, in a simulation of its applicability in the planning of activities to build an electrical energy sub transmission line of 69,000 volts. The aim of this study was to compare two methods of project management: PERT / CPM and Critical Chain Method (CCPM) in the building of this line. The methodologies adopted were a case study, seeking to understand by documental analyze of records the shape and the behavior of the planning by PERT / CPM and a experimental research, through planning simulation using the Critical Chain Method. In conclusion, this study showed that the CCPM reduces the deadlines and absorbs the deviations, without compromising the delivery of projects, since there are a commitment of the professionals involved and a radical change in the organizational culture of the enterprise analyzed. / Nos últimos anos muito se tem falado a respeito de gerenciamento de projetos e de como as suas contribuições são importantes para as organizações que buscam excelência e efetividade em seus empreendimentos. Segundo o Project Management Institute (PMI), é estimado que 25% do PIB mundial estejam destinados a projetos, caracterizando cada vez mais o reconhecimento e a importância dessa metodologia e aumentando a sua difusão. As organizações que adotam essa metodologia de gerenciamento buscam vantagens competitivas, novas oportunidades de trabalho e até mesmo a conquista de outros mercados. Mas o que se percebe é que muitas organizações simplesmente não conseguem cumprir os prazos estabelecidos em seus planejamentos, e, diante dessa carência, apresenta-se neste trabalho o método de planejamento de tempos em projetos denominado Método da Corrente Crítica, que é a aplicação da Teoria das Restrições no ambiente de projetos, em uma simulação de sua aplicabilidade no planejamento das atividades de construção de uma Linha de Subtransmissão de energia elétrica de 69.000 volts. O objetivo deste estudo foi confrontar dois métodos de gerenciamento de projetos: o PERT/CPM e o Método da Corrente Crítica (CCPM) na construção dessa linha. As metodologias adotadas foram um estudo de caso, buscando entender através da análise documental de registros a forma e o comportamento do planejamento por PERT/CPM, e uma pesquisa experimental, por meio de uma simulação de planejamento utilizando o Método da Corrente Crítica. Como conclusão, este trabalho mostrou que o método CCPM reduz os prazos e absorve os desvios, sem comprometer a entrega dos projetos, desde que existam um comprometimento dos profissionais envolvidos e uma mudança radical na cultura organizacional da empresa analisada.

An analysis of the causes and impact of rework in construction projects

Simpeh, Eric Kwame January 2012 (has links)
A dissertation presented to the Higher Degrees Committee of the Cape Peninsula University of Technology in fulfilment of the requirements for the degree of Master of Technology: Construction Management, 2012 / This study investigated the underlying causes of rework in construction projects and the impact on overall project performance so that effective containment and reduction strategies can be developed. The objectives of the study were as follows: (i) to determine the influence different project types have on the causes of rework in construction projects; (ii) to determine the impact of rework on organisational and project performance; (iii) to determine the influence various project types have on rework costs (direct and indirect) in construction projects; (iv) to determine the influence various procurement methods have on total rework costs in construction projects; (v) to design and develop rework reduction and containment strategies. The research was motivated by several international and local studies demonstrating a lack of concern for the root causes of rework and the potential impact on cost, overall project performance, and the ‘value-addedness’ to the completed project. The research approach adopted included an exploratory and main study targeting purposively selected construction professionals and stakeholders in the Cape Peninsula metropolitan area of the Western Cape Province. The exploratory case study was carried out at the initial stage of the study to gain more insight into the causes and impact of rework on overall project performance. Specifically, data was collected by means of observation of physical works, semi-structured interviews with relevant parties directly involved in site operation and the analysis of site instruction record documents. The main study obtained data from 78 construction professionals and stakeholders via questionnaire survey, a survey conducted among design consultants and contractors in the general building category ranging from grade 3 to 9 who are registered with Construction Industry Development Board (CIDB). Descriptive, inferential statistics and probability distribution functions were used to analyse the data. The findings revealed that changes initiated by the client, changes initiated by the design team due to errors and omissions, poor coordination, and finally, integration among the design team were the major contributing factors to rework. Moreover, non-compliance with specifications, setting-out errors, low labour skills, and emphasis on time and cost aggravated the occurrence of rework on site. The study revealed that while there is no significant difference between the causes of rework and various project types, rework can and often does make a significant contribution to any project’s cost overrun. The total mean cost of rework as a percentage of the original contract value for new build project and refurbishment/renovation projects was 4.89% and 6.28% respectively. However, rework costs do not differ relative to project type or procurement method. Furthermore, the study revealed that cost overruns, time overruns and design team dissatisfaction all impacted on project performance. The findings indicate that designrelated rework can be minimised by implementing the following strategies: team building, involvement of subcontractors and suppliers, and design for construction. Moreover, involvement of subcontractors during construction, and the implementation of quality control and site quality management systems could also lead to reduction in rework during the construction phase. Furthermore, the probabilistic analysis of rework occurrence was determined in the projects selected; this analysis predicts the occurrence of rework so that a quantitative risk assessment could be undertaken prior to the commencement of construction. The research concludes by recommending that design and construction firms must develop organisational measurement systems for recording rework occurrence and its associated costs. It is by determining the frequency and costs of rework that effective strategies for its containment and reduction can be identified.
