Software Development Models:

A software cycle deals with various parts and phases from planning to testing and deploying. All these activities are carried out in different ways, as per the needs. Each way is known as a Software Development Lifecycle Model (SDLC).
Software life cycle models describe phases of the software cycle and the order in which those phases are executed. There are lots of models, and many companies adopt their own, but all have very similar patterns.

Incremental Model

An incremental model is an intuitive approach to the waterfall model. Multiple development cycles take place here, making the life cycle a ” multi – waterfall cycle. Cycles are divided up into smaller, more easily managed iterations. Each iteration passes through the requirements, design, implementation and testing phases.

A working version of the software is produced during the first iteration, so you have working software early on during the software life cycle. Subsequent iterations build on the initial software produced during the first iteration.

Advantages of Incremental model:

  • 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 iteration is an easily managed milestone.

  1. I do agree with all the ideas you’ve presented on your post.
    They are very convincing and will definitely work.
    Nonetheless, the posts are too short for starters.
    Could you please prolong them a bit from next time? Thanks for the post.

  2. Hello there I am so excited I found your site, I really found you by error, while
    I was researching on Digg for something else, Nonetheless I am here now and would just like to say thanks
    a lot for a fantastic post and a all round entertaining blog (I also love the theme/design), I don’t
    have time to read it all at the minute but I have saved it and also included your RSS feeds, so when I have time I will be back to read
    more, Please do keep up the great work.

  3. Woah! I’m really digging the template/theme of this blog.
    It’s simple, yet effective. A lot of times it’s hard to
    get that “perfect balance” between user friendliness and appearance.
    I must say you’ve done a great job with this. Additionally, the blog loads
    super quick for me on Safari. Outstanding Blog! adreamoftrains website hosting companies
