Adoption of Inventory Information Systems and Warehouse Performance: Empirical Evidence from the Medical Stores Department, Tanzania

Abstract

Purpose: This study examined the influence of inventory information systems on warehouse performance at the Medical Stores Department (MSD), Tanzania. Specifically, the study assessed user efficiency, error reduction, and system integration as key dimensions of inventory information systems affecting warehouse operations. Methodology: The study employed a quantitative approach and descriptive research design. The target population consisted of 100 employees from the Procurement Management Unit and warehouse departments at MSD Headquarters and Mabibo Zonal Office. A sample of 80 respondents was selected using stratified and simple random sampling. Data were collected through structured questionnaires using a five-point Likert scale and analysed using IBM SPSS Version 28. Multiple regression analysis was applied to determine the effect of inventory information systems on warehouse performance. Findings: The findings revealed that inventory information systems had a positive and statistically significant effect on warehouse performance (β = .360, t = 3.326, p = .001). Effective system utilization improved transaction speed and accuracy, reduced manual recording errors, strengthened stock accuracy, and enhanced information flow between procurement and warehouse functions. System integration also supported real-time stock tracking and inventory monitoring. Unique Contribution to Theory, Practice and Policy: The study recommends strengthening user capacity, improving automated inventory controls, and enhancing integration between EPICOR-10, eLMIS, procurement, warehousing, inventory control, and distribution functions. These measures are expected to improve inventory visibility, reduce stock discrepancies, strengthen coordination, and enhance warehouse performance at MSD.
