System analysis involves studying activities mathematically to define goals and procedures to accomplish them efficiently. A system has interconnected parts that form a complex whole with organization, interaction, interdependence, and integration toward a central objective. Key drivers of system analysis include business needs like growth, acquisitions, or productivity. Analysts use development lifecycles like waterfall, spiral, or rapid application modeling along with tools like prototyping to plan and implement new efficient systems.

2. • The act, process, or profession of
studying an activity typically by
mathematical means in order to
define its goals or purposes and to
discover operations and
procedures for accomplishing
them most efficiently.

10. Developmental tools and techniques
•System analyst must know how to use a variety of
techniques such as modeling, prototyping, and c
computer-aided, and implement formation system.
•System analysts work with these tools in a team
environment.

11. Benefits of a system analysis (SA)
•Learning to use system that somebody else created
•Planning new system
•Reducing errors when problem solving
