The environment may be so dynamic in such a way that the system is rendered less meaningful than it should have been just the moment it is introduced. However, this card be due to a number of factors namely:

1. The process system development is so lengthy and complication such that along time period such that the completion of the system, user needs may have changed or new and better systems may be available.
2. Due to the complexity of the system development life cycle lack of adequate expertise may render the system developed less meaningful and insensitive to its intended use.
3. User resistance may also act as a stumbling block to the proper use of the new system thus rendering it obsolete.
