SDLC
- 1. SDLC Software Development life cycle Presented to : Mr.Junaid Present by: MUHAMMAD ROBEEL
- 2. Agenda: • Introduction • SDLC Phases • Advantages
- 3. Introduction: • The SDLC is a framework that describes the activities performed at each stage of a software development project. • SDLC process is used by the software industry to design, develop and test high quality software. It aims to produce the quality software that meets or exceeds customer expectations, reaches completion within time and budget.
- 5. SDLC Phases: 1. Planning and Requirements Analysis 2. Defining Requirements 3. Designing the Software 4. Building or Developing the Software 5. Testing the Software 6. Deployment and Maintenance
- 6. 1.Planning & Requirement Analysis: 1. Requirement analysis is the most important and fundamental stage in SDLC. 2. It is performed by the senior members of the team with inputs from all the stakeholders and domain experts or SMEs in the industry. (small-to-medium- enterpise ). 3. Planning for the quality assurance requirements and identification of the risks associated with the project is also done at this stage.
- 7. Requirements Analysis 1) Business Requirements 2)Stakeholder Requirements 3) Solution Requirement a. Non-functional Requirements b. Functional Requirements 4) Transition Requirements
- 8. 2. Defining Requirements Once the requirement analysis is done the next step is to clearly define and document the software requirements and get them approved from the project stakeholders. This is done through ‘SRS’ – (Software Requirement Specification ) document which consists of all the product requirements to be designed and developed during the project life cycle.
- 9. Defining Requirements • Enterprise Analysis • Business Analysis Planning & Monitoring • Elicitation • Requirements Analysis • Requirements Management &Communication • Solution Assessment & Validation
- 10. 3. Designing the Software • Based on the requirements specified in SRS, usually more than one design approach for the product architecture is proposed and documented in a DDS. –( Design Document Specification). • This DDS is reviewed by all the stakeholders and based on various parameters as risk assessment, design modularity , budget and time constraints , the best design approach is selected for the software.
- 11. 4. Developing the Software • In this stage of SDLC the actual development starts and the product is built. The programming code is generated as per DDS during this stage. • Developers have to follow the coding guidelines defined by their organization and programming tools like compilers, interpreters, debuggers etc are used to generate and implement the code.
- 12. 5. Testing the Software • This stage is usually a subset of all the stages assign the modern SDLC models, the testing activities are mostly involved in all the stages of SDLC. • However this stage refers to the testing only that stage of the software where defects are reported, tracked, fixed and retested, until the software reaches the quality standards defined in the SRS.
- 13. 6. Deployment and Maintenance • Once the software is tested and no bugs or errors are reported then it is deployed. • Then based on the feedback, the software May be released as it is or with suggested enhancements in the target segment. • After the software is deployed then its maintenance starts.
- 14. Advantages of Choosing an Appropriate SDLC • Increased development speed • Increased product quality • Improved tracking & control • Improved client relations • Decreased project risk • Decreased project management overhead
