    Software Evolution Laws

    - The laws for software evolution were laid down by Lehman. He divided the software into three different categories:

    S-type (static-type)
    - This software works strictly according to the defined specifications and solutions.
    - The solution and method required to achieve it, are immediately understood before coding.
    - This software is least subjected to changes hence it is called the simplest of all software.
    - For example, calculator program for mathematical computation.

    P-type (practical-type)
    - This software consists of a collection of procedures.
    - It is defined by exactly what procedures can do.
    - In this software, the specifications is described but the solution is not obvious instantly.
    - For example, gaming software.

    E-type (embedded-type)
    - This type of software works closely as the requirement of real-world environment.
    - It has a high degree of evolution as there are various changes taking place in laws, taxes etc. in real world situations.
    - For example, Online trading software.
