    A model for indertaking business process re-engineering (BPR) to improve construction project performance in Tanzania
    (University of Dar es Salaam, 2019) Mwishwa, Yazidi Hassan Bakari
    The performance of construction projects in Tanzania is commonly plagued with time overrum, cost overrun and poor quality. These problems are deeply rooted in weaknesses of project processes. This thesis improve the project processes and project performance through BPR philosophy. The BPR model was developed based on the concepts of process performance measurement and BPR philosophy. Data used to develop the model was obtained through interviews and questionnaire surveys from 33 selected organizations. Data from a case study of a road construction project together with the critical comparative analysis of a BPR model against other models were used to validate the model. The dimensions of the developed model include: BPR foundation; Understand Current Process; Weaknesses of Current Processes; Desired (To-Be) Processes and Continuous Improvement. The model considers design, procurement and construction management as core project processes. The Model also analysed indicators for identifying weaknesses and for driving improvement. The thesis has established forty (40) indicators to identify process weaknesses and fourteen measures to identify desired project process. With regard to strategies to enable continuous improvement, the study proposes continuous learning, benchmarking, use of IT technology, plan resources and adopt Capability Maturity Model. Model was validated to identify weaknesses, identify desired (To-Be) process, enable improved project processes, identified weaknesses of traditional processes and compared with the other models. The study concludes that forty established indicators are appropriate to identify process weaknesses; fourteen measures are useful to design To-Be process. They can be deployed through using of the proposed strategies for improvement. Suggestion is made for each contracting party in the country to use the model to undertake BPR to improve performance of core project processes.
