A change request is a formal proposal to change a system, product, service, document or project baseline. It is typically submitted using a tool or document that captures requirements and meta information that can be used to assess and prioritize the change. The following are illustrative examples of change requests.
Data
A bank's customer service team discovers that customers are accidentally paying the wrong bill. The business team responsible for the site investigates and finds that two companies have similar descriptions and billing account formats. They submit a change request that the merchant descriptions be changed in the database reference table to make a clear distinction between the two companies.
Functionality
An air conditioner manufacturer is in the middle of a product development project when they realize that a new air purification function can't be controlled properly from the remote control unit. They submit a change request to include new buttons on the remote control.
Documentation
A train manufacturer determines that a procedure for tuning brakes is incorrect and leads to malfunctions. They issue an urgent communication to maintenance teams and submit a change request to update the procedure in equipment manuals.
Non-Functional
The non-functional requirements for a particular part in a communications satellite state that the part should be resistant to temperatures up to 90 degrees celsius. Risk identification processes identify this as a risk. As part of risk management, a change request is submitted to increase this requirement to 120 degrees celsius, or 248 degrees fahrenheit.
