Install the System Components

• Installation Schedule
• Tasks, person assigned to it, time schedule
• Installation procedures and controls
• To maintain data integrity and cross check the
  old and new systems
• Contingency plan
• Old or new system fails during conversion
• Timetable for dismantling old system

Post-Implementation Evaluation

• Post Implementation Report
• Generally 2-3 months after the cutover
• System Quality
• Project Management
• Organizational Relevance

10
Evaluation Process

• Review Project Documents
• Old system, promised system, and the delivered
  system
• Plan the review
• Conduct interviews
• Prepare the report
• Submit the report to management
