System Analysis and Design
- System Analysis – This involves studying the requirements of either the existing system or a new system in order to design an effective system.
- System Design – Involves the process of creating a well-structured system with careful consideration of objectives and requirements.
Approaches to Development
Attempts to make system development less of an art and more of a science usually referred to as engineering techniques, are applied to system development. Techniques are:
- Prototyping – Designing and building a scaled-down but fundamental version of a desired system is known as prototyping.
- Joint Application Design(JAD) – Users, managers, and system developers are brought together for a series of intensive structured meetings run by a JAD session leader.
- Participatory Design(PD) – Each user has an equal share in determining system requirements and in approving system design
System Analysis and Design Interview Topics for Freshers
System Analysis is the “what” before the “how” in system design. It provides the essential roadmap for crafting a system that is both effective and efficient in solving the intended problem. “Imagine you’re building a dream house. You wouldn’t start hammering nails without a detailed blueprint, right?”The same goes for software development.”
System analysis is the blueprint, while system design translates it into the actual system.
