Incremental lifecycle model

Incremental model is an evolution of waterfall model. The product is designed, implemented, integrated and tested as a series of incremental builds. It is a popular model software evolution used many commercial software companies and system vendor.
Incremental software development model may be applicable to projects where:
  • Software Requirements are well defined, but realization may be delayed.
  • The basic software functionality are required early

    Advantages
    Disadvantages
     
    • Generates working software quickly and early during the software life cycle.
    • More flexible - less costly to change scope and requirements.
    • Easier to test and debug during a smaller iteration.
    • Easier to manage risk because risky pieces are identified and handled during its iteration.
    • Each phase of an iteration is rigid and do not overlap each other.
    • Problems may arise pertaining to system architecture because not all requirements are gathered up front for the entire software life cycle.
     
       
    Software Lifecycle Selector  

    Lifecycle selector saves your time and money!

    Success or failure of the software projects greatly depends on right chose software development lifecycle model. Many software developers make the big mistake of using only one software development lifecycle model (SDLCM) for all software projects. Our tool helps avoid this problem.
    Lifecycle Selector is a absolutely free, very useful and easy to use software engineering and software project management tool. Only answer Yes or No for some questions you can to select Software Lifecycle model maximally preferable for the project. more
