5.3 SYSTEM IMPLEMENTATION
Involves application development, testing, documentation, training, data conversion, system changeover, and post-implementation evaluation of the results
System Installation & Evaluation
5 Steps in systems implementation
1) prepare a separate operational and test environment
2) provide training for users, managers, and IT staff
3) perform data conversion and system changeover
4) carry out post-implementation evaluation of the system
5) prsent a final report to management
Operational & test environment
the environment that analysts and programmers use to develop and maintain program is called the test environment
a separate test environment is necessary to maintain system security and integrity and protect the operational environment
Training
no system can be successful without proper training, whether it involves software, hardware, or manufacturing
training plan = the three main groups for training are users, managers, and IT staff
vendor training = includes the purchase of software or hardware, then vendor-supplied training is one of the features you should investigate in the RFPs (requests for proposal) and RFQs (requests for quotation) that you send to potential vendors
webinars, podcasts, and tutorials = many vendors offer Web-based training options, including Webinars, podcasts, and tutorials
Outside Training Resources = look into an independent training firm to provide in-house hardware or software training
training tips = train people in groups, with sepsrate training programs for distinct groups
interactive training = relationship exists between training methods and costs
Data conversion
existing data is loaded into the new system
depending on the system, data conversion can be done before, during or after, the operational environment is complete
System changeover
direct cutover is similar to throwing a switch that instantly changes over from the old system to the new
parallel operation requires that both system run simultaneously for a specified period, which is the slowest method
Post-implementation task
2 additional tasks
1) Prepare a post-implementation evaluation
2) deliver a final report to management
