If I could restart my product career from several years ago, this would be my chosen starting point. Forget Agile and Scrum for a moment (though they're important); we need a foundation.
If I were starting in product today, I wish someone had explained the Software Development Life Cycle (SDLC) to me.
So, what is the SDLC? It's a process for producing high-quality, low-cost software in the shortest time possible. Before I begin any project, whether it's a new feature or an enhancement to existing functionality, this is the process I follow.
Every product has a lifecycle, whether it's a new iPhone/Android iteration, a new car model, software update, or even garden furniture. Ignoring the need for iteration and enhancements would be misguided; products need improvement to stay relevant. The SDLC provides a repeatable process for this.
Planning:
Objective: Define the scope, purpose, and objectives.
Activities: Feasibility study, resource allocation, scheduling, risk analysis, goal definition. Output: Project plan, cost estimation, timeline.
Requirement Analysis:
Objective: Gather and analyse business requirements.
Activities: Stakeholder meetings, interviews, surveys, document analysis.
Output: Requirement Specification Document (SRS).
Design:
Objective: Create system architecture and design.
Activities: System design, database design, UI/UX design, prototyping.
Output: Design Specification Document, prototypes, design models.
Implementation (Coding):
Objective: Translate design into code.
Activities: Writing code, developing modules, unit testing, version control.
Output: Source code, libraries, build scripts.
Testing:
Objective: Ensure the software meets requirements and is defect-free.
Activities: Writing test cases, unit tests, integration tests, system tests, user acceptance tests (UAT).
Output: Test plans, test cases, bug reports, test summary reports.
Deployment:
Objective: Release software to production.
Activities: Deployment planning, environment setup, code deployment, review.
Output: Deployed application, release notes, user manuals.
Maintenance:
Objective: Provide ongoing support and updates.
Activities: Bug fixing, performance tuning, software updates, technical support.
Output: Updated software versions, patches, maintenance reports.
Evaluation (Optional):
Objective: Assess project's success and gather feedback.
Activities: Post-implementation review, feedback collection, performance evaluation, documentation of lessons learned.
Output: Evaluation report, feedback analysis, future project recommendations.
Importance of Each Stage:
Planning: Ensures the project meets goals and stays on schedule and budget.
Requirement Analysis: Ensures the product meets stakeholder needs, avoiding costly overruns.
Design: Provides a solid foundation for a good user experience and efficient performance.
Implementation: Correctly translates design into functional code.
Testing: Catches defects before production, ensuring quality.
Deployment: Ensures a smooth release without disrupting production.
Maintenance: Keeps the software functional and user-friendly.
Evaluation: Provides insights for improvement in future projects.
Fail to follow these stages, and you risk project overruns, increased costs, poor user experience, and lower ROI. Each stage of the SDLC is crucial for delivering successful projects.
