Software is considered to be a collection of executable programming code, associated libraries and documents. Software when made for specific requirement is called software product. Engineering on other hand , is all about developing products, using well defined , scientific principles and methods. Software engineering  is an engineering branch associated with development of software product using well-defined scientific principles, methods and procedures. The outcome of software engineering is an efficient and reliable software product. Software Evaluation is the process of developing a software product using software engineering principles and methods. Software Evaluation LAWS: Lehman devided software into 3 categories. 1.s-type : static type    works strictly according to defined specifications and solutions.Ex : calculator program 2.p-type
