This study examined the productivity of the Automation of Procurement and Accounting Data Entry (APADE) system, in a before/after quasi-experimental design that measured outputs (workload, productivity), inputs (staff size, staff grade structure, usuage of overtime), and by-product social effects (annual leave, sick leave, and leave without pay) using archival data. While workload decreased , the procurement action lead time (PALT) decreased by 55% after APADE implementation. This result was obtained as the size of the staff decreased and overtime usuage declined sharply. The implementation ofAPADE streamlined the document process significantly at the test site.
