4. Introduction
 The Software Development Life Cycle (SDLC)
is a structured and systematic approach to the
development, maintenance, and management
of software applications.
 Aimed at ensuring the successful delivery of
high-quality software products.
 Ensures efficient development, high-quality
products, and customer satisfaction.

5. Phases of SDLC

6. Planning Phase
 Define project scope, objectives, timelines, and
resources.
 Requirement gathering: Engage with
stakeholders to Identify and document project
requirements, including
-Functional
-Non-functional,
-Technical specifications.

7. Planning Phase(cont.)
 Feasibility study: Assess the technical,
financial, and operational feasibility of the
project to determine its viability.
 Project planning: Develop a comprehensive
project plan outlining tasks, milestones,
schedules, and resource allocations.

8. Analysis Phase
 Understand end-user requirements and system
functionalities.
– Requirement analysis: Analyze and refine the
gathered. Requirements.
– Creating system specifications: Document detailed
system requirements..
– Prototyping: Develop prototypes to visualize and
validate the proposed solution with stakeholders.

9. Design Phase
– Architectural design: Define the overall structure
and components of the software system.
– Database design: Design the database schema,
tables, relationships etc.
– UI/UX design: Design the user interface and user
experience to ensure usability, accessibility.
– Algorithm design:To implement the system's
functionality efficiently.

10.  Build the software based on the design
specifications.
– Coding:
– Unit testing
– Integration testing
Development Phase

11. Testing Phase
Ensure the software meets quality standards and is
free of defects.
– Functional testing: Verify that the software meets the
specified requirements
– Security testing:data breaches, unauthorized access, and
system vulnerabilities.
– User acceptance testing: Involve end-users to validate
the software's usability, functionality, and compliance with
their needs.

12. Colour - Good
 Release the software for production use.
– Installation: Deploy the software to production
environments
– Data migration: Transfer data from existing systems
or sources to the new software solution
– User training: Provide training and support to end-
users.

13. Maintenance Phase
 Provide ongoing support, updates, and
enhancements.
– Bug fixing: Identify, prioritize, and resolve software
defects and issues
– Feature enhancements: Implement new features,
functionalities, or improvements
– Performance optimization: Optimize the software's
performance, efficiency, and reliability.

14. Conclusion
 The SDLC is the backbone of effective
software development, providing a structured
approach from planning to maintenance.
 By following SDLC principles, we ensure that
our projects are delivered efficiently, meeting
the needs of our clients while driving innovation
in technology solutions.
