Software Process (PROCESS ACTIVITIES (SOFTWARE DESIGN & IMPLEMENTATION…

- - - - feasibility
      - requirement elicitation and analysis
      - requirement speccificcation
      - requirement validation
  - - - architectural design
      - interface design
      - component design
      - database design
  - - - component testing
      - system testing
      - acceptance testing
- - - - requirement analysis and definition
      - system and software design
      - implementation and unit testing
      - integration and system testing
      - operation and maintenance
    - - difficulty of accomodating change
  - - - cost of accomodating chaarging reduced
      - easier to set customer feedback
      - more rapid delivery and deployment
    - - process is not visible
      - structure tends to degrade
  - - - component analysis
      - requirement modification
      - system design with reuse
      - development and integration
- - - - to be used requirement engineering process, design process. testing process
    - - make the program easy to use
      - clients will like it more as it is closer to their ideals
      - better designs
      - easy to maintain
      - easier to be developed (save time)
    - - ADVANTAGE
        
        Only focus only one requirement at a time to have a specific feedback from the user
      - DISADVANTAGE
        
        High expectation from the end user which makes the development of the system to be misleading
  - - - Lower risk
      - Early increments act as prototype so it can help to elicit another requirements for the next increments
      - Highest priority tested frequently
    - - Conflicts with the procurement model
  - - - Each loop in the spiral represents a phase in the process
      - Reduce the risks throughout the process
    - - Development & validation
      - Planning
      - Risk assessment & reduction
      - Objective setting
    - - introduce risk-driven approach
      - help people think of iteration in software processes
