A System Development Life Cycle is the process of developing a system or software. Prototype is the process of creating examples of software applications,
When business organization facing a keen (鋒利的) competition in the market, rapid change of technology and fast internal demand, system development is necessary. In the system development, a business organization could adopt the systematic method for such development. Most popular system development method is system development life cycle (SDLC) which supports the business priorities of the organization, solves the identified problem, and fits within the existing organizational structure.

SDLC is software development life cycle and system analysis & design is one of the step in the cycle. Other steps being: 1. Requirement analysis 2. System analysis & design 3. Coding 4. Testing 5. Installation & maintenance
Adjusting scope during the life cycle can kill a projectNo working software is produced until late during the life cycle.High amounts of risk and uncertainty.Poor model for complex and object-oriented projects.Poor model for long and ongoing projects.Poor model where requirements are at a moderate to high risk of changing.from http://www.phonemania.com.pk/
*Each phase of an iteration is rigid and do not overlap each other. * Problems may arise pertaining to system architecture because not all requirements are gathered up front for the entire software life cycle.
advantages and drowbacks of following a life cycle approach to information system development?
Advantages of system development life cycle in terms of waterfall model it only requires minimal resources in implementing this method. But it is hard to go back and change.
No, that is false.
False.

A System Development Life Cycle is the full sequence of events in the creation, use, maintenance and retirement of a computer system. Different service providers use different methodologies, with different naming conventions to describe the cycle.

During the DESIGN PHASE of the SDLC or "System Development Life Cycle" is where a detailed plan for programmers to follow is developed.
