Understanding of Technical Documents
In-depth study of Technical documents helps the re-engineering team to understand the rationale and considerations behind original development effort. It helps the team to place the re-engineering effort in a continuum with existing application. Such analysis helps optimization of cost and development effort to execute reengineering tasks.
Understanding of Business Application
With System analysis, the re-engineering team gauges current state of the Business application. The team thus, understands the implementation of business flow and the problems associated with it. Further, the functionalities are compartmentalized into problematic and non-problematic. Moving forward, we strive to imbibe existing non-problematic functionalities, seeking to make best use of existing knowledge and experience while work on problematic areas. Such reengineering approach optimizes systems, proving much more effective and efficient than new development.
While ‘Understanding business’ defines current state, gap analysis envisions the next level. New business requirements are carefully scrutinized and matched with what the existing system can offer. The space between the business expectations and current system potential is highlighted, and scope of re-engineering is defined.
