The paper examines the adoption of the Supply Chain Management practices on the performance of Banks in Kenya. This research conceptualizes and develops four dimensions of SCM practice (outsourcing of goods & services, information & communication technology, strategic supplier partnership, and globalization) and tests the relationships between SCM practices, and organizational performance. The study employed descriptive design. Data for the study was collected using a self-administered questionnaire procedure, where the questionnaires were administered to the selected respondents through drop and pick later technique. A sample size of 33 respondents was drawn from the sample frame using simple stratified random sampling technique to promote the needs for efficiency and representativeness from various branches and outlets of Postbank as an organization in Nairobi County and the relationships proposed in the framework was tested using Chi-square, T-test among other statistical tools. Data was analyzed by aid of Statistical Package for Social Sciences (SPSS). The study will be useful in the academic circles as it will contribute immensely towards filling the gaps in knowledge in the area of service industry. The study found that outsourcing was important to the banks only when the appropriate methods are employed. It also found that ICT had a major role in determining the performance of banks as it dictated the mode of transaction and data they displayed to clients. Strategic partnership was also important based on what it intended to achieve in enhancing the performance of banks. Lastly, globalization is equally vital as it increases competition and exposes local banks to global scene to experience how performance of banks can be improved. The study recommends that correct ICT methods should be applied to promote the competitiveness of banks and improve performance. Also it recommends that outsourcing be done only if they promote the objectives and goals of the banking institute.
