【ICT】Exam Question/Practice🌟 SEM 3
STPM Trial Question
7. Every project should carry out five phases of systems
development life cycle (SDLC) which are planning, analysis, design,
implementation and maintenance.
a) Explain why the planning phase is important in SDLC.
The aim of planning phase is to determine the needs of
developing a new information system. In this phase, the system analyst (with
the cooperation of the customer) investigates the current or existing system to
get right information. It is because without right information it is not possible
to develop a good system.
b) Briefly explain five documentations delivered from the
planning phase in SDLC.
1. Economic feasibility – measures whether the lifetime
benefits of the proposed information system will be greater than its lifetime
cost.
2. Technical feasibility – measures whether the company has
or can obtain the hardware, software, and people needed to deliver and then
support the proposed information system.
3. Operational feasibility – measures how well the proposed
information system will work.
4. Social feasibility – measures whether the proposed system
can be accepted by the society.
5. Legal feasibility – measures whether the proposed system
violate the laws of the country or not.
6. Schedule feasibility – looks at how long the system will
take to develop, or whether it can be done in a desired time-frame.
