Appropriate change management in an organization information system as well as in other areas allows organizations to lower the risk of those changes impacts. The right estimation of the change effect demands a lot of experience. CorSet contains a type list of critical factors of a change (in the structure of assumptions and impacts both inside and outside the organization). The target board of changes is adjusted to the conditions in the organizations within the public sector.

The use is for such changes connected with:

• New information technology implementation
• Legislative changes
• Process changes
• Other areas

The Procedure – use of CorSet

1. Use of the type list of impacts and assumptions of a change
2. Use of principles of requirement management
3. Use of the Map of processes to identify the requirement management
4. Use of the type information architecture to identify the impacts on the information system.
