Proper inventory management has a significant effect on project performance. Construction companies play a major role in setting up and completing projects that contribute to the overall growth of an economy. Over the past years, the construction companies in Nairobi have been experiencing performance-related challenges in their projects. At times, inventory costs run beyond the estimates, which eventually results in losses for the firms. Some of the large construction companies have many projects with fixed prices based on the contracts, and they sometimes bear the risk of cost overruns. The companies sometimes experience interrupted operations because the inventory runs out of stock. However, most of them have insufficient inventory management approaches.
