    Assessment of supplier appraisal and rating in procurement entities in Ghana
    (2014-08-22) Inkoom, Kofi
    Previously commonly used supplier appraisal criteria have solely focused on quality, service or delivery and price. Literature have in recent years suggested that some instruments or criteria for appraising suppliers were just about measuring quality and other quantitative measures such as price and service at the very most (Doney and Cannon 1997; Wilson 1994). As a matter of fact many existing appraisal measures fail to consider other important factors in appraising suppliers which are mostly qualitative in nature. The purpose of the research is to identify how buying organizations appraise suppliers and to identify the key supplier competencies (criteria) currently appraised on. The study also pinpoints those variables that have been identified by research as crucial elements of a buyer-supplier relationship but have been frequently omitted in the supplier appraisal processes. Findings however reveal that only few of responding firms have a formal supplier appraisal process in place and that other factors were not predominantly considered in the supplier appraisal process.The study also makes use of both qualitative and quantitative approaches for methodology where interviews and questionnaire will be used as data collection instruments. It also sought to identify challenges and weaknesses in the appraisal processes as well as its strengths with the view of suggesting recommendations that could be used to reinforce the processes. Recommendations included proper reviewing of weighting criteria, supplier rewards, short courses or training, debriefing, Reinforcement of Institutional structures and frequency of assessment.

    Evaluating the causes of delays in construction projects, case study: Ghana Ports and Harbours Authority
    (2021-06-15) Inkoom, Kofi;
    The issue of construction project delays is commonplace in Ghana. Major infrastructure projects undertaken by Ghana ports and Harbours Authority experience the issue of delays. Port expansion and other infrastructure improvement projects undertaken by GPHA, have all exceeded their proposed completion dates. This research sought to evaluate the causes of construction project delays using Ghana Ports and Harbours Authority as a case study. The study aimed to find the important causes of delay in construction projects and to identify the critical negative effects of the delays on construction projects undertaken by GPHA. A questionnaire survey was conducted among purposively sampled respondents who have collaborated with GPHA on different construction projects. Quantitative method of research was adopted for data gathering. Using the Relative Importance Index (RII) technique. The findings revealed that the important causes of project delays were, Political interference; Insufficient data collection and surveys before designs leading to errors; Inadequate cash flow due to non-payment; Unexpected ground conditions. Again time overruns, cost overruns and disputes between contracting stakeholders were established to be the critical negative effects of delays on construction projects undertaken by GPHA
