2. Agenda:
 SDLC
 Models:
 Water Fall Model.
 Spiral Model.
 Agile Model.

3. SDLC:
 Stands for Software Development Life
Cycle.
 Standard model used word wide to
develop a software.
 Necessary to ensure the quality of the
software.
 Logical steps taken to develop a
software product.

5. SDLC:
1. Analysis.
2. Planning.
3. Implementation.
4. Testing.

6. 1-Analysis:
 The first and the most important phase
in the SDLC.
Determine where the problem is.
 Breaking down the system.
 Requirements.
Must be done carefully.
Any error in this phase will cost a lot !!

7. 2-Planning:
Determine who will do what !
 Tasks are assigned to team members.
 It all starts here.

8. 3-Implementation:
-The most expensive phase.
 Also the longest one!

9. 4-Testing:
 The never ending phase.
 In this phase we TEST, TEST, TEST,
and TEST.
 Very important phase.

10. SDLC Models:
 Water Fall Model
 Spiral Model
 Agile Model

11. Water Fall Model:
The waterfall model is
the oldest and most
widely used model in the
field of software
development.

12. Advantages & Disadvantages:
 Advantages:  Disadvantages:
 Linear model.  Unidirectional.
 Documentation.  Unclear requirements
lead to confusion.
 Testing (software
coding).  Client’s approval is in
the final stage.

13. Spiral Model:

14. Advantages & Disadvantages:
 Advantages:  Disadvantages:
 Large and complicated  Works on complicated
projects. projects only.
 Adaptability with  An experienced and
changes. skilled team are
required.
 Testing at each phase.

15. Agile Model:
Requirements
Design
Implementation
Prioritize
Verification

17. Key Features of Agile Software
Development:
 Iterative.
 Active Customer involvement.
 Fixed Time.
 Priority based delivery.

18. Key Features of Agile Software
Development (cont’d):
 Adaptive.
 Empowered Teams.
 Rapid development.
 Simplicity.

19. Agile working flow STORY BOARD:

20. Advantages & Disadvantages:
 Advantages:  Disadvantages:
 Customer Satisfaction.  Not suitable for handling
complex dependencies.
 Saves Time.
 More risk of
 Testing.
sustainability,
maintainability and
extensibility.
 Suitable for fixed or
changing requirements.  Strict delivery
management dictates
. the scope, functionality
to be delivered, and
adjustments to meet the
deadlines.

21. Summary:
 SDLC
 SDLC Models:
 Water Fall Model.
 Spiral Model.
 Agile Model.
