IT Re-engineering - BPR

Any IT System re-engineering or a Business Process Re-engineering can be done following ways :

1. Big-Bang Approach : This approach is the once where the current system is replaced with NEW SYSTEM and NEW PROCESSES all at once. Eg: Current systems A1 ...Z1 is being replaced with A2....Z2 with change in systems and processes.

2. Incremental Approach : This approach is to improve or replace the existing system one small piece at a time.

3. Modular Infrastructure Approach : In this approach, the modular infrastructure that at first would function in parallel with but eventually would supersede the current infrastructure
