Transcript

  • 1. CHAPTER 5 Requirements analysis
  • 2. = Systematic requirements analysis is also known as requirements engineering
  • 3. =>The term requirements analysis can also be applied specifically to the analysis proper, as opposed documentation of the requirements, it is also a critical to the success of a development project
  • 4. Stakeholders – are persons or organizations (legal entities such as companies, standards bodies) which have a valid interest in the system.
  • 5. It is increasingly recognized that stakeholders are not limited to the organization employing the analyst.
    • Other stakeholders will include:
    • anyone who operates the system (normal and maintenance operators)
    • anyone who benefits from the system (functional, political, financial and social beneficiaries)
  • 6.
    • anyone involved in purchasing or procuring the system. In a mass-market product organization, product management, marketing and sometimes sales act as surrogate consumers (mass-market customers) to guide development of the product
    • organizations which regulate aspects of the system (financial, safety, and other regulators)
    • people or organizations opposed to the system (negative stakeholders)
    • organizations responsible for systems which interface with the system under design
  • 7. System Context Diagram A System Context Diagram (SCD) in software engineering are diagrams that represent the actors outside a system that could interact with that system
  • 8. System context diagrams are related to Data Flow Diagram, and show the interactions between a system and other actors with which the system is designed to interface and it can be helpful in understanding the context which the system will be part of.
