Implementation Phase

The implementation phase involves installing approved applications into production environments. Primary tasks include announcing the implementation schedule, training end users, and installing the product. Additionally, organizations should input and verify data, configure and test system and security parameters, and conduct post-implementation reviews. Management should circulate implementation schedules to all affected parties and should notify users of any implementation responsibilities.

After organizations install a product, pre-existing data is manually input or electronically transferred to a new system. Verifying the accuracy of the input data and security configurations is a critical part of the implementation process. Organizations often run a new system in parallel with an old system until they verify the accuracy and reliability of the new system. Employees should document any programming, procedural, or configuration changes made during the verification process.


Management should conduct post-implementation reviews at the end of a project to validate the completion of project objectives and assess project management activities. Management should interview all personnel actively involved in the operational use of a product and document and address any identified problems.

Management should analyze the effectiveness of project management activities by comparing, among other things, planned and actual costs, benefits, and development times. They should document the results and present them to senior management. Senior management should be informed of any operational or project management deficiencies.
