This study examined supplier relationship management and Non-Government Organization’s performance in Uganda. Its main aim was to assess the relationship between tailored vendor relationship, strategic material sourcing and collaborative specification development on NonGovernment Organizations’ performance. A descriptive research design was used to obtain information from a sample of 89 people. Statistical Package for Social Scientists was used to analyse the data and thereafter a Pearson correlation method was applied to test the relationship between supplier relationship management and the performance of Non-Government Organizations.

The results revealed that there was weak positive relationship between tailored vendor relationship and performance of Non-Government Organizations at Pearson correlation coefficient value ofr =.218 at significance value of .040. The findings further revealed that there was moderate positive relationship between strategic material sourcing and Non-Government Organization performance at Pearson correlation coefficient of r = 0.411 at .000 value of significance. Furthermore, the findings also revealed that there was a weak positive relationship between collaborative specification development and Non-Government Organization performance at Pearson correlation coefficient calculated value of r = 0.223 at .036 value of significance. Therefore, the study concludes that there is positive relationship between supplier relationship management and Non-Government Organization performance.It recommends that Non-Government Organisation should strengthen, promote and preserve their good relationship with their suppliers.

This would motivate the suppliers to perform their tasks without any inconvenience to the organization. Non-Government Organisations should also maintain and improve the involvement of suppliers in the development of specifications in order for their suppliers to reduce their cost of doing business.
