Risks in changing the IS of an organization reflects the events that can affect the flow of business.
Based on what I have read and understood, these are some of the risks associated with changing the IS/IT:

Inconsistency of data
- Variations in the way data is collected may affect the consistency of the information being gathered and thus, affects the operations in an organization.

Incomplete system
- unfinished or incomplete systems can greatly hinder the progress of an organization.

Irrelevance of information
- Information that is inappropriate, unnecessary, or too detailed for effective decision making has
no value.

In addition to that, poorly programmed or systems lacking in proper security can be easily manipulated and it may disrupt the flow of work that will lead to incorrect decisions or impaired planning.

Having new or changing the information system can be a tasking job. But then, if used properly and accordingly, the organization can benefit from it. The success of implementing new or changing the system depends on the accuracy of the technical deployment and also the people's acceptance of the change. As always, proper education and communication are the keys in helping the implementation of the change in the information system in an organization.
