2. INTRODUCTION TO SDLC
 SDLC Stands for System Development Life Cycle.
 The system development life cycle (SDLC) is
a framework defining tasks performed at each step in
the software development process.
 It consists of a detailed plan describing how
to develop, maintain and replace specific system.

3. OBJECTIVE OF SDLC
 SDLC has Three primary objectives:
 Ensure the delivery of high quality systems.
 Provide strong management control.
 Maximize productivity.

4. SDLC PHASES

5.  Determine if a new system is needed
 Three primary tasks:
 Define the problem.
 Suggest alternative solutions.
 Prepare a short report.
Phase 1: Planning

6. Phase 2: System Analysis
 In depth study of the existing system to
determine what the new system should do.
 In addition to observation and interviews,
examine:
 Formal lines of authority (org chart)
 Standard operating procedures
 How information flows
 Reasons for any inefficiencies

7. Phase 3: System Design
 It takes the initial input
 For each requirements design elements will be
produced
 It describes the software features and includes
hierarchy diagrams , screen layout diagrams
 The output of the stage describe the new
system as a collection of modules or
subsystems.

8. Phase 4: System Development
 Build the system to the design specifications
 Develop the software
 Acquire the hardware
 Create manuals for users and operators

9. PHASE 5: SYSTEM TESTING
 Test the new system
 Module (unit) test - tests each part of
system
 Integration testing - tests system as one
unit

10. Phase 6: System Implementation
 Convert from old system to new system.
 Train users
 Compile final documentation
 Evaluate the new system
 User Training

11. Phase 7: System Maintenance
 Physical repair of the system.
 Correction of new bugs found.
 System adjustments to environmental changes.
 Adjustments for users’ changing needs
(adaptive).
 Changes to user better techniques when they
become available (perfective).
