Reference Model in Software Development – a boon for Project Manager

Jaideep Khanduja Jaideep Khanduja Profile: Jaideep Khanduja

A reference model is a non-arbitrary model of software that is to be referred to when a new software requirement comes from a customer. The reference model will suit and fit most of the requirements given by the customer. The model is the most ideal scenario befitting the technical and functional requirements. Although the new architecture built may not (and will never) match point to point with the reference model but still it has to be as near to it as possible. Infact the reference model has to be capable to address all technical issues that may arise during the software development. During the development if a new problem is encountered, it becomes the part of reference model too. For development also the different components of the repository of the reference model are picked and absorbed wherever found suitable. So the various components are picked and fixed as it is in the software or are reworked with minor changes keeping requirements in mind.

This process not only shortens the development timeframe but also brings in more accuracy and stability in the product. It also helps the project manager to present the near to exact time and cost estimations. The reference model acts as a block of utilities or functions meant for the software being built. The best suitable blocks are selected and placed as it is. The most suitable blocks are selected and placed with a little modification. This increases the reusability as well. Reference model works as an outline sketch of the new product being developed.
