Software-Development-Cycle-SDLC and its phases.pptx

The Software Development Life Cycle (SDLC) is a structured approach to software development that defines phases such as planning, design, development, testing, deployment, and maintenance. It provides a framework for efficiently and effectively building high-quality software, ensuring that requirements are met, risks are managed, and deadlines are achieved.

3. Introduction Software Development Life Cycle SDLC, or Software Development Life Cycle, is a structured and systematic approach to developing software products. It includes a detailed plan for the entire process, from initial concept to finished product.

4. Phases of SDLC 1 Planning 2 Defining 3 Designing 4 Building 5 Testing 6 Deployment

5. Planning Understanding Needs Identifying and analyzing project requirements and objectives in detail. Feasibility Study Evaluating if the project can be implemented within the available resources. Cost Estimation Calculating the estimated cost to develop the software product.

6. Defining In this stage, all the requirements for the target software are specified. These requirements get approval from customers, market analysts, and stakeholders.

7. Designing 1 Architectural Design The high-level design that explains how the different parts of the system will interact. 2 Database Design Designing the database structure and relationships. 3 User Interface Design Creating the interface through which the user interacts with the software.

8. Building Coding Writing the code for the software product according to the design. Testing Performing various testing methods to ensure quality. Integration Combining all the modules into a complete system. Implementation Deploying the software for actual use by end-users.

9. Testing Unit Testing Testing individual units or components of the software. Integration Testing Verifying the interactions between different software modules. System Testing Testing the complete and integrated system as a whole. Acceptance Testing Evaluating if the system meets the acceptance criteria.

10. Deployment 1 Release The product is released to the market. 2 Installation Installation and configuration of the software at the customer's end. 3 Maintenance Ongoing support, bug fixes, and updates.

11. Life Cycle Models 1. Waterfall Model 2. Agile Model

12. Waterfall Model It is the fundamental model of the software development life cycle. This is a very simple model.In the waterfall model, once a phase seems to be completed, it cannot be changed, and due to this less flexible nature, the waterfall model is not in practice anymore.

13. Agile Model The agile model was mainly designed to adapt to changing requests quickly. The main goal of the Agile model is to facilitate quick project completion. The agile model refers to a group of development processes. These processes have some similar characteristics but also possess certain subtle differences among themselves.

14. Agile vs Waterfall

15. Advantages of SDLC 1. Enhances Product Quality Systematic and constant testing at every stage of software development. 2. Improves Project Management Continuous Monitoring and Tracking 3. Manages Risks Effectively Risk assessment and analysis 4. Enhances Product Quality Documentation & Reporting

16. Conclusion Evaluation Analyzing the success and scope for improvements in the SDLC process. Ongoing Improvements Identifying areas for enhancement and innovation in future projects. Lifecycle Cost Consideration Lifecycle Cost Consideration in SDLC involves factoring in the total expenses associated with software development, including initial development etc..
