TOPIC 5.3 SYSTEM IMPLEMENTATION
System Installation & Evaluation
You developed and tested programs individually,
in groups, and as a complete system.
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. Present a final report to management
5 report you should include:
• Final versions of all system documentation
1 more item...
A post-implementation evaluation should examine all aspects of the development effort and the end product --the developed information system.
2 additional tasks:
Prepare a post-implementation evaluation
Deliver a final report to management.
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.
there are 4 changeover methods
1. direct cutover
2. parallel operation
2 more items...
– Involves more risk than other changeover
methods
6 types of training:
Webinars, Podcasts, and Tutorials
Outside Training Resources
Vendor Training
Training Tips
Training plan
Interactive Training
The environment for the actual system operation is called the operational environment or production environment.
The environment that analysts and programmers use to develop and maintain programs is called the test environment.
System Implementation
The initial task is application development, which requires systems analysts and programmers to work together to construct the necessary programs and code modules.
