Prevailing software development engagement models inject significant risks into client’s change management journey. The gap in value realization between the Client expectation vis-à-vis the prevailing approaches is very high. Exility reduces this gap significantly which translates to lower Total Cost of Ownership (TCO) for the client.
Users validate requirements by reviewing visual components as against mockups or Word documents. Users experience dynamic behavior when validating requirements.
Visual components can be changed rapidly and submitted for user validation even though the underlying backend database and programs are not developed. The impact of requirement changes emerging later in the development cycle is minimized through higher level of automation.
Visual components are built in such a manner, that upon validation by Users, they represent a deterministic requirements contract with Analysts and Developers. Developers work with “necessary and sufficient conditions” when developing the database and data access programs.
Since the product is custom built, Users are not under pressure to leverage out of the box functionality as is typical to COTS implementations. By providing better support to evolving requirements, Users are weaned away from requesting features early in the project when there is less clarity.
Induct new team members faster because the application design can be understood without having to decipher code. Impact assessment of enhancement requests is faster as clear separation of UI, business logic and database makes it is easier to localize changes.
Minimize impact of technology change on code by expressing business design using technology independent methods. Clear separation of functionality aspects such as UI, business logic and database ensures that the entire code is not affected by change in any one of them.
Developers with combination of skills are not required since clear separation of functionality is enforced.
Unlike COTS packages there is no need to perform maintenance activities that have no relevance to the implemented footprint. Additional cost of maintaining custom code is also eliminated.
Exility engagement approach accelerates how we manage risks well beyond the first production install and into the sustenance phase. Thus, it reduces the cycle time of implementing the business initiative while ensuring sustained value to clients
