Why should the tasks of systems development and maintenance be segregated from operations?
What will be an ideal response?
The segregation of systems development (both new systems development and maintenance) and operations activities is of the greatest importance. Systems development and maintenance professionals acquire (by in-house development and purchase) and maintain systems for users. Operations staff should run these systems and have no involvement in their design and implementation. Consolidating these functions invites fraud. With detailed knowledge of an application's logic and control parameters along with access to the computer operations, an individual could make unauthorized changes to application logic during execution. Such changes may be temporary (on the fly.) and will disappear with little or no trace when the application terminates.
