Program Plan Intro

Business Requirements:

  • The specific business requests system should meet so as to be successful.
  • The entire system development effort is driven by business requirements.
  • The business requirements are gathered through investigation.
  • The users identify all business needs of organization and take measurements for these needs.
  • The methods to gather requirements includes:
    • Conducting user interviews to determine current issues and operations.
    • Surveying employees through questionnaires for discovering issues.
    • Making observations to determine manner in which current operations are been performed.
    • Reviewing business documents for discovering policies, reports and how information is been used in organization.

Ambiguous Business Requirements:

  • An ambiguous requirement means that multiple readers may interpret the same thing in different ways.
  • It may rise due to inadequate participation of end users during design and analysis phases.
  • It may occur commonly in reports due to different mindset of developers and users.

QUESTION 3 Requirements are the “blueprints” that everyone involved on the project uses to work from. Systems development process models play very significance role in the building of information systems. However, challenges with project teams in selecting appropriate models can affect the entire project. Critically discuss why poor documentation of system requirements and poor selection of appropriate systems development process models is a challenge in systems development. NB: Appropriate referencing of works is highly required. A plagiarized work will be rejected and forwarded to academic dishonesty committee. NB: Support your justification with relevant literature with articles indexed in high reputable places such as Scopus. Use journal articles such as Journals in IEEE Xplore, ACM digital library, Association for Information Systems (AIS) eLibrary, IET library, Engineering Index of Elsevier, BCS computer Journals etc. At least 70% of the justifications should come from scientific…
