A Dissertation Submitted to the Mzumbe Dar es Salaam Campus College in partial fulfillment of the requirements for the award of Master of Science in Procurement and Supplies Chain Management (MSC.PSCM) Degree of Mzumbe University.This study attempted to establish the Adoption of Procurement Best Practices in the Private Sectors. The objective was to investigate if private sectors recognize the presence of both the procurement regulations and its authority and determine whether they adhere to Best Procurement Practices and investigate its operational performance. The researcher selected Banking Industry as the case study whereby questionnaires, interviews and direct observations were used in collecting data in Dar es Salaam City. Dar es Salaam City was selected because it is where the Head offices of the Banks are located. This is because almost all procurement functions are centralized to Head offices of the respective Banks. Both probability and non - probability sampling techniques were employed in selecting 25 respondents. Microsoft word was employed to analyzing data and the study revealed the following. Firstly, the findings revealed that majority of the supplies officers recruited for the procurement activities in Banks are not procurement professionals. Generally, they are accounting professionals, but they are given short courses to acquire the necessary skills regarding procurement. Secondly, it was revealed that, Top Management and other departmental heads do interfere with the procurement process before the end. This is contrary to the guidelines. But again it was revealed that the organization structure of Banks does not have the Procurement Management Unit, hence technical advice is normally requested from other departments such as marketing department, human resources, information and communication technology. Lastly, the study recommends to the Bank’s management to develop the Financial Regulations that are comprehensible and deploy a big part of the sections from the Public Procurement Act and should leave the procurement officers independent.
