5.3)SYSTEM IMPLEMENTATION
System Implementation
The system must be tested
and documented carefully , users must be trained, and existing data must be converted.
System Installation & Evaluation
The new system now is ready to go to work.
5 steps in systems implementation:
Perform data conversion and system changeover
During data conversion , existing data is loaded into the new system.
System changeover is the process of putting the new information system online and retiring the old system.
The four changeover methods are
Parallel operation
Easier to verify that the new system is working properly under parallel operation than under direct cutover
Pilot operation
The group that uses the new system
first is called the pilot site
Direct cutover
Involves more risk than other changeover methods
Phased operation
The risk of errors or failures is limited to the implemented module only
Carry out post implementation evaluation of the system
Perform two additional tasks:
Prepare a post implementation evaluation
Deliver a final report to management.
Provide : training for users, managers, and IT staff
System requires training for users , managers, and IT staff members.
Present a final report to management
Your report should include the following
Recap of all systems development costs and schedules
Comparison of actual costs and schedules to the original estimates
Planned modifications and enhancements to the system that have been identified
Post implementation evaluation, if it has been performed
Final versions of all system documentation
Prepare a separate operational and test environment
Specific combination of hardware and software.
