摘要:The various activities that are undertaken when developing software are commonly modeled as a software development life cycle. It begins with identification of requirements of software and ends with retirement of software .The SDLC is the progression of high level task that are used to develop software. It is the first step in project planning process. There are no. of different models of software development life cycle like, waterfall model, prototyping, Spiral, Iterative, and so on. The prototype model imitates effort to increase the flexibility of the development process by permitting the customer to interact with a working model of the product. The major problem to be faced that the management some time consider the prototype as final model. This will lead to a problem as prototype is not complete and no one can measure the reliability, complexity and efficiency. Through the Pareto principal, we can minimize this problem up to certain extent. A principle named after Vilfredo Pareto that specifies an unequal relationship between inputs and outputs. The principle states that for many phenomena, 20 % of invested input is responsible for 80% of the results obtained. Put another way, 80% of the consequences stem from 20% of the causes. It is also referred to as the “Pareto Rule” of the “80/20 Rule”.
