Many failed systems were abandoned because analysts tried to build wonderful systems without understanding the organization.
The primarily goal is to create value for the organization.

The systems analyst is a key person analyzing the business, identifying opportunities for improvement, and designing information systems to implement these ideas.
It is important to understand and develop through practice the skills needed to successfully design and implement new information systems.

Planning (Why build the system? How should the team go about building it?)
Analysis (Who uses system, what will it do, where and when will the system be used?)
Design (How will the system work?) Implementation (System delivery)

Pros Cons
Identifies systems requirements long before programming begins
Minimizes changes to requirements asproject progresses
Design must be specified on paper before programming begins
Long time between system proposal and delivery of new system

The Systems Development Lifecycle consists of four stages: Planning, Analysis, Design, and Implementation
There are six major development methodologies: the waterfall method, the parallel development method, the phased development method, system prototyping, design prototyping, and agile development.
There are five major team roles: business analyst, systems analyst, infrastructure analyst, change management analyst and project manager.
