Types of Change
Changes might be technical or contractual as shown in the following figure.
Technical changes. Technical changes result from the implementation of the solution. Normally, the changes are generated internally and are within the scope of the project. An example of a technical change is implementing a program that automates test cases. This program helps improve the quality of the testing.
Contractual changes result from changes in the terms and conditions, the scope of work, the requirements, schedule, and costs. Normally, contractual changes are externally generated and out of the project scope. For example, the sponsor might ask IBM to include maintenance of a system as part of a purchase agreement for the system with IBM.For both technical and contractual changes, a formal change management procedure must be established.
