📘 Application Lifecycle Management (ALM) & Methodologies

🔄 What is ALM?

  • ALM = managing the entire life of an application → from ✍️ design → 💻 development → 🧪 testing → 🚀 release → 🔧 maintenance.
  • Provides a framework for bug fixes, enhancements, and smooth delivery.
  • Stages:
    1️⃣ Plan Release
    2️⃣ Develop
    3️⃣ Test
    4️⃣ Build Release
    5️⃣ Test Release
    6️⃣ Release

✨ Benefits:
✅ Efficiency & productivity
✅ Avoids defects (quality assurance)
✅ Predictable & consistent releases
✅ Faster delivery
✅ Lower cost
✅ Long-term stability & maintenance

⚙️ Development Methodologies

💧 Waterfall

  • 📏 Linear steps → each must finish before next.
  • Good for: stable requirements, compliance-heavy projects, fixed deadlines.
  • Pros: predictable cost/time, strong docs, structured process.
  • Risks: ❌ inflexible, ❌ little feedback, ❌ slow to adapt, ❌ risk of dissatisfaction.
  • Governance:
    • 📋 Change Control Board (CCB)
    • 📅 Milestone reviews

⚡ Agile

  • 🔄 Iterative, flexible approach (sprints = 2–4 weeks).
  • Requirements evolve → continuous delivery & stakeholder input.
  • Pros: adaptability, collaboration, early value delivery.
  • Risks: ⚠️ scope creep, ⚠️ quality trade-offs, ⚠️ integration challenges, ⚠️ weak docs.
  • Governance:
    • 🗂 Backlog prioritization
    • 📣 Daily stand-ups
    • 🔍 Sprint reviews & retrospectives

🏉 Scrum (Agile framework)

  • Core values: 💪 Commitment, 🦁 Courage, 🎯 Focus, 🔓 Openness, 🙏 Respect
  • Roles: Product Owner, Scrum Master, Dev Team
  • Meetings: planning, daily stand-ups, reviews, retrospectives
  • Artifacts: backlog, sprint backlog, burndown chart, increments

🍃 Lean (Agile framework)

  • ✂️ Eliminate waste, ♻️ continuous improvement, 📈 efficiency + quality
  • Principles: Identify value → Map value stream → Create flow → Establish pull → Seek perfection

📋 Kanban (Agile framework)

  • 👀 Visual board → cards flow left → right
  • 🔢 WIP limits → avoid overload
  • ⏱ Metrics: cycle time & throughput
  • Flexible → embraces small, incremental changes

🔀 Hybrid

  • 🧩 Mix of Waterfall (structure, upfront docs) + Agile (flexibility, feedback)
  • Good for: complex integrations, mid-sized companies balancing old & new.
  • Risks: ⚠️ confusing rules, ⚠️ high overhead, ⚠️ resource strain.
  • Mitigation: 🎓 training, 📢 clear scope, ⛳ phase-gate reviews

🛡 Governance Strategies

Governance = structure to control changes, align priorities, ensure security/compliance.

  • Waterfall: CCB + Milestone reviews
  • Agile: backlog priority, daily stand-ups, sprint ceremonies
  • Benefits: ✅ efficiency, ✅ transparency, ✅ compliance, ✅ resource optimization
