Reasons why changes to a system are so necessary after they become operational
Amendments to the original system will almost inevitably occur in addition to the computerisation of additional company activities. 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.
Reasons why changes to a system may be so necessary after it becomes operational.
1. The technology today is still considered to be at infancy and so as technology grows, there is the need to incorporate new and superior ideas into the system.
2. The external environment such as government policies, consumer behaviour and suppliers expectations brings about changes in the external policies and requirements resulting to the adjustment of the existing system.
3. Internal users expectations and requirements arising from management policy considerations could also result to changes of the existing system.
4. The business industry to which a particular company belongs obviously consist of a number of players and so each will develop his own strategies to outwit the other. This battle for competitive advantage will result to adjustments and changes to the existing system.
5. The existing system may develop internal control weaknesses such as the input, output, processing, storage and security limitation or a general dissatisfaction of the current system.
6. The management may desire to obtain modern technological facilities or management advancement acquiring new pieces of hardware for software which would result to efficiency and effectiveness of the current system.
