Overview
This lecture introduces the software development life cycle (SDLC) using a cooking analogy, guiding students through the process of building a user-focused app by examining every phase from analysis to deployment.
Introduction & Social Media Engagement
- Stay active on social media using #FNBacademy and WhatsApp for updates and prizes.
- All lessons are recorded and available on the Learning Management System (LMS).
Guardian Health App Case Study
- Success was achieved by addressing a real health problem, engaging with communities, and building credibility via awards.
- Building connections and team credibility is essential, especially when lacking industry-specific backgrounds.
Introduction to App Development & SDLC
- Apps should solve real user problems, not just exist for their own sake.
- The SDLC is compared to preparing a meal: understanding diners = knowing your app’s users.
SDLC Phase 1: Analysis
- Identify the target user (end user is often different from the paying client).
- Analyze client and user needs, pain points, core features, budget, and timelines.
- Triple your time/budget estimates to accommodate unforeseen challenges.
- Gather detailed requirements and iterate with client feedback before proceeding.
SDLC Phase 2: Design
- Translate requirements into a practical, user-friendly interface and feature set.
- Use wireframes and prototypes (hand-drawn or software) to visualize app layout.
- Menus should be visible, easy to use, and allow for future expansion.
- Focus group and client feedback are used to refine the design.
SDLC Phase 3: Development
- Develop the UI, app logic, and required integrations (e.g., maps, weather APIs).
- Ensure alignment with approved analysis and design documents.
- Maintain consistency and simplicity throughout the app for ease of use.
SDLC Phase 4: Testing
- Test for functionality, usability, and stress (performance under heavy usage).
- Iteratively fix bugs and improve based on tester and user feedback.
- Aim for an intuitive experience; users should not need instructions.
SDLC Phase 5: Deployment & Improvement
- Deploy the app after thorough testing.
- Gather user feedback and refine the app accordingly.
- Start with a Minimum Viable Product (MVP) and add features based on real user needs.
- Continually update and improve the app to keep users engaged and stay competitive.
Key Terms & Definitions
- SDLC (Software Development Life Cycle) — The structured process of planning, creating, testing, and deploying an app.
- Wireframe — A basic visual guide to suggest the structure of an app or website.
- End User — The person who actually uses the app, not necessarily the one who commissions or pays for it.
- MVP (Minimum Viable Product) — An initial app version with the minimum features required for functionality and user value.
Action Items / Next Steps
- Log in to the LMS to access instructions for building the Pine City Zoo app.
- Review past lesson recordings as needed.
- Stay engaged and share progress on social media platforms.
