User Training User Training
Need to consider the same 2 groups: End users
Use the system to achieve the business purpose Creating, modifying, deleting records Generating reports Querying the data
System operators Perform administrative functions and routine
maintenance to keep the system operating Starting and stopping the system Running backup and recovery

Training Methodologies Determine best training method
given end-users and system: Instructor Led One-on-One User-Led External sources

Training the end-users What do users want?
Training early on Training manual Straightforward teaching techniques
1. How to get started 2. Where to turn for help 3. Who to see when they want to learn
more about the features and functionality

Maintenance Phase Maintenance:
Changes made to a system to fix or enhance its functionality
Why is this needed? Corrective Perfective Adaptive Preventive

Maintenance Steps Obtain maintenance requests
SSR, SMR, CR Controlling maintenance requests
How is decision made on which maintenance requests to work on?
Planning steps Secure resources
Transform requests into formal changes Develop test criteria and a test plan

Maintenance Phase/Testing Start with “production copy” of modules
to be changed Check out production version of source code Unit testing REGRESSION testing
To ensure changes have not created new problems in the system
Accomplished by running a subset of previously executed integration and system tests
Smart IS shops keep a regression “test bucket” of selected test cases to run on a system when changes are made to any module in that system

Other things to consider Cost of maintenance CASE tools to aid in maintenance Cost factors Who does maintenance in an
organization
