⚙️ Software Development Life Cycle (SDLC) — Standard Steps

1. Requirement Analysis

Goal: Understand what needs to be built and why. Activities:

• Gather requirements from stakeholders or clients
• Define functional and non-functional requirements
• Create Software Requirement Specification (SRS)
• Identify constraints, dependencies, and risks Deliverables: SRS document, Use Case diagrams, Requirement Matrix

---

2. Planning

Goal: Define how the project will be executed. Activities:

• Define project scope and objectives
• Create project plan and timeline (Gantt chart)
• Estimate resources, cost, and effort
• Assign roles and responsibilities
• Risk assessment and mitigation plan Deliverables: Project Plan, Resource Plan, Cost Estimation Sheet

---

3. System Design

Goal: Convert requirements into a technical blueprint. Activities:

• Define system architecture (frontend, backend, database, API)
• Design UI/UX prototypes and workflows
• Define data models and schema
• Choose tech stack, tools, and frameworks Deliverables:
• System Architecture Diagram
• Database ERD
• UI/UX Wireframes
• Design Document (High-Level & Low-Level Design)

---

4. Development (Implementation)

Goal: Convert design into working code. Activities:

• Set up repositories, environments, and CI/CD pipelines
• Develop modules based on coding standards
• Perform unit testing during coding
• Version control (Git branching and merging) Deliverables:
• Source Code
• Build Scripts
• Code Documentation
• Unit Test Reports

---

5. Testing

Goal: Ensure the product meets quality standards. Activities:

• Conduct various tests (unit, integration, system, UAT, performance, security)
• Log and fix bugs
• Regression testing after fixes Deliverables:
• Test Plan
• Test Cases
• Bug Reports
• QA Sign-off Document

---

6. Deployment

Goal: Move the tested build to production. Activities:

• Prepare deployment plan
• Set up production servers or cloud environments
• Deploy code via CI/CD
• Verify successful release and rollback plan Deliverables:
• Deployment Guide
• Release Notes
• Production Build

---

7. Maintenance & Monitoring

Goal: Keep the system running smoothly post-deployment. Activities:

• Monitor system performance and user feedback
• Apply patches, bug fixes, and updates
• Perform backups and security audits Deliverables:
• Maintenance Reports
• Performance Logs
• Update/Upgrade Documentation

---

Optional (Advanced Teams Only):

8. Continuous Improvement (Agile / DevOps Loop)

• Implement CI/CD pipelines
• Collect feedback and release incremental updates
• Automate testing and monitoring for better velocity
