    Communication
    - This is the first step where the user initiates the request for a desired software product.
    - He contacts the service provider and tries to negotiate the terms.
    - He submits his request to the service providing organization in writing.

    Requirement Gathering
    - This step onwards the software development team works to carry on the project.
    - The team holds discussions with various stakeholders from problem domain and tries to bring out as much information as possible on their requirements.
    - The requirements are contemplated and segregated into user requirements, system requirements and functional requirements.
    - The requirements are collected using a number of practices as given -

    1. studying the existing or obsolete system and software,
    2. conducting interviews of users and developers,
    3. referring to the database or
    4. collecting answers from the questionnaires.

    Implementation
    - It means installing the software on user machines.
    - At times, the software may need post-installation configurations at user end.
    - Software is tested for portability and adaptability and integration related issues are solved during implementation.

    Disposition
    - As time elapses, the software may decline on the performance front.
    - It may go completely obsolete or may need an intense upgrade.
    - Hence a pressing need to eliminate a major portion of the system arises.
    - This phase includes archiving data and required software components, closing down the system, planning disposition activity and terminating system at appropriate end-of-system time.
