Experimental Design and Observational Studies in the Impact of Irrelevant and Misleading Information on Software Effort Estimation

Nowadays software manufacturers are faced with a bewildering task with regard to development software meeting customer requirements and expectations, achieving the desired level of quality, and making development within the budget and schedule. Although there are many estimating tools available that can be used for software development, many projects still suffer from late completion time and exceed budgets. A great number of software applications fail to meet user requirements and quality requirements and result in unacceptable maintenance costs. So we reduce the length of specifications without changing the main content. Existing projects drawbacks are listed out. Avoid short development period. And create the awareness about the irrelevant contents in the project requirements. To do that, we developed the project in laboratory environment. Laboratory settings can be useful to demonstrate the existence of an effect and better understand it.
