    Software Development Life Cycle (SDLC) Software Development Life Cycle (SDLC) Presentation Transcript

    •  
    • Agenda:
      • SDLC
      • Models:
        • Water Fall Model.
        • Spiral Model.
        • Agile Model.
    • SDLC:
      • Stands for Software Development Life Cycle.
      • Standard model used word wide to develop a software.
      • Necessary to ensure the quality of the software.
      • Logical steps taken to develop a software product.
    •  
    • SDLC:
      • Analysis.
      • Planning.
      • Implementation.
      • Testing.
    • 1-Analysis:
      • The first and the most important phase in the SDLC.
      • Determine where the problem is.
      • Breaking down the system.
      • Requirements.
      • Must be done carefully.
      • Any error in this phase will cost a lot !!
    • 2-Planning:
      • Determine who will do what !
      • Tasks are assigned to team members.
      • It all starts here.
    • 3-Implementation:
      • -The most expensive phase.
      • Also the longest one!
    • 4-Testing:
      • The never ending phase.
      • In this phase we TEST, TEST, TEST, and TEST.
      • Very important phase.
    • SDLC Models:
      • Water Fall Model
      • Spiral Model
      • Agile Model
    • Water Fall Model: The waterfall model is the oldest and most widely used model in the field of software development.
    • Advantages & Disadvantages:
      • Advantages:
        • Linear model.
        • Documentation.
        • Testing (software coding).
      • Disadvantages:
        • Unidirectional.
        • Unclear requirements lead to confusion.
        • Client’s approval is in the final stage.
    • Spiral Model:
    • Advantages & Disadvantages:
      • Advantages:
        • Large and complicated projects.
        • Adaptability with changes.
        • Testing at each phase.
      • Disadvantages:
        • Works on complicated projects only.
        • An experienced and skilled team are required.
    • Agile Model: Prioritize Verification Implementation Design Requirements
    •  
    • Key Features of Agile Software Development :
      • Iterative.
      • Active Customer involvement.
      • Fixed Time.
      • Priority based delivery.
    • Key Features of Agile Software Development (cont’d):
      • Adaptive.
      • Empowered Teams.
      • Rapid development.
      • Simplicity.
    • Agile working flow STORY BOARD:
    • Advantages & Disadvantages:
      • Advantages:
        • Customer Satisfaction.
        • Saves Time.
        • Testing.
        • Suitable for fixed or changing requirements.
      • Disadvantages:
        • Not suitable for handling complex dependencies.
        • More risk of sustainability, maintainability and extensibility.
        • Strict delivery management dictates the scope, functionality to be delivered, and adjustments to meet the deadlines.
    • Summary:
      • SDLC
      • SDLC Models:
        • Water Fall Model.
        • Spiral Model.
        • Agile Model.
