Information Systems Development Process
• Phase 1 – Feasibility Study• Phase 2 - Requirements Gathering• Phase 3 – Software Design• Phase 4A – Development (only for bespoke software, not
relevant for ERPs)• Phase 4B – Configuration (only relevant for ERPs not for
bespoke software)• Phase 5 – Testing• Phase 6 – Implementation• Phase 7 – Post Implementation Review
