01 What are the stages of the System Development Life Cycle?
The stages are:
• Recognition of need
• Feasibility study.
• Analysis
• Design
• Implementation
• Post-Implementation
Recognition of need :
One must know what the problem is, before it can be solved. Then
the required information is improved.
Example: A supervisor may want to investigate the system flow in
purchasing.
R Report on Recognition of need
• Introduction :
• Problem :
• Necessity :
• Economic Value :
Conclusion
Feasibility study and Report on it :
Depending on the results of the initial investigation, the survey is
expended to a more detailed feasibility study.
A feasibility study is a test of a system proposal according to its
workability, impact on the organization, ability to meet user needs
effective use of resources. It focuses on three major questions:
• User’s demonstrable needs
• Resources available to solve problem
• The procedure to fit it within the organization’s master MIS

plan.
Result of the feasibility study:
The result of the feasibility study is a formal proposal. This is
simply a report. The proposal summarizes what is known and what is
going to be done. It consists of the following.
• Statement of the problem
• Summary of findings and recommendations
• Details findings (with raw materials, users of finished good
• Recommendations and conclusions.
Analysis :
Analysis is a detailed study of the various operations performed by
a system and their relationships within and outside of the system.
Once the analysis is completed and depending on this analysis
we/it moves to the design phases.
Report on Analysis :
Introduction :
• Category of user :
• List of product :
• Raw Materials
• Making Process
• Conclusion :
• Design phase :
The most creative and challenging phase of the system life cycle
is system design. The term design describes a final system and the
process by which it is developed. Graphically design phase can be
explained as follows.
