“…Consultant qualification selection and selection based on consultant’s qualification are similar methods in which the borrower requests expressions of interest from eligible companies and selects the one with the best qualifications and experience for further negotiations. These methods are appropriate for small-scale or emergency contracts, where the preparation and evaluation of competitive bids are of concern (Ng and Chow, 2004; Nomir, 2021).…”

Purpose International development projects are a dominant means by which aid is distributed to countries. Over the past 70 years, the distribution of trillions of dollars of development aid has been mediated by the United Nations (UN). However, most of this aid has failed to deliver the expected outcomes for which it was assigned. Nevertheless, a significant proportion of projects can be considered successful. Despite the glaring question as to which factors contribute to the success or failure of projects, no study has comprehensively documented the relationship between procurement mechanisms invoked to deliver aid projects and project outcomes. This study aims to assess this relationship. Design/methodology/approach Leveraging network analysis methodology, this study examines the World Bank data set of over 247,000 developmental contracts worldwide granted over the past 20 years. It identifies the range of procurement practices used and interrogates their ability to deliver satisfactory project outcomes. Findings Eleven prevalent practices are identified covering aid projects across twelve sectors. As might be expected, Africa is the largest recipient of aid, while the Middle East is the least. Overwhelmingly, international competitive bidding (ICB) is the leading procurement procedure, both in terms of contract number and total dollar value. However, ICB does not always deliver the best outcomes, with other, more boutique approaches sometimes doing better. Social implications The breadth of this study, encompassing such a vast data resource, and generating such a rich pool of findings will now empower researchers to take the next important step, which is to progress this study in exploring why it is that certain procurement strategies have worked for some sectors, but not others. Countries, financial institutions, the UN and construction enterprises alike will be very interested in the results. Originality/value The spectrum of outcomes identified will be of interest to academics and practitioners alike wishing to investigate further the drivers behind the results described here.

In today's challenging industry conditions, where being good is not enough to be successful, companies trying to be the best, need consultancy in different fields. Consulting firms provides consultancy services to businesses, and they need to determine the most appropriate one for them. Fuzzy MCDM (Multi Criteria Decision Making) methods are appropriate to solve consulting firm selection problem. In this study, consulting firm selection problem of a textile company operating in Istanbul, Turkey is handled by using a novel combined fuzzy MCDM method based on IMF-SWARA (Improved Fuzzy Stepwise Weight Assessment Ratio Analysis) and F-CODAS (Fuzzy COmbinative Distance-based Assessment) methods. The importance weights of the criteria are calculated with IMF-SWARA method. Findings indicate that the top three important criteria are respectively, experience, references, and reliability. Then, F-CODAS method is used to rank the consulting firms and the best one is presented to the Human Resources department of the textile company. This study contributes to the existing literature in various aspects. It suggests a novel combined fuzzy MCDM method to solve consulting firm selection and a new Fuzzy CODAS based on TFNs is proposed. Moreover, HR managers can use the findings of this study to evaluate consulting firms.
