The incremental model incorporates both linear and parallel process flow as you can observe in the image above.Īny iteration of the increment model can use prototyping model for the process flow.

The final product has more chances of being accurate and reassures all the requirements of the customer. This stripped-down version helps the customer to evaluate the released increment and suggest modifications which can be implemented in later increments. The initial increment is the stripped-down version of the complete system. So in this way, the incremental model delivers the project in parts. The further increment would produce features like spell check, grammar checking, mailing, and so on. In the next release or increment, the delivered functionality would include sophisticated editing tools, advanced file creation capabilities. So, in the first release, the delivered increment possess file management, document production, editing like functionalities.

Let us understand the incremental model with the help of a scenario.Ĭonsider, we have to deliver a word processor to the customer and customers want the delivery of his product by a date that seems to be impossible. The incremental model suggests that the delivered early increments should possess the functionality of customer’s interest and let the re st of the software to be delivered in a period. And soon the complete working system will be delivered to him. Receiving early delivery of the operational product (in parts) boosts the morale of customer that his requirements are being satisfied. The incremental model produces a working product (in parts) at each increment. Incremental model is a process model used by developers to develop software. Further, we will discuss the types, advantages and disadvantages of an incremental model. We will also consider the scenario when the incremental model can be used. In this section, we will discuss the characteristics of the incremental model in brief, along with its phases.
