• 🧠 Development approach = how you plan and execute a project

Key Ideas:

• Some projects are hard to change once started (e.g., building a house) → changes are expensive and complex
• Some projects are easy to adjust during work (e.g., mobile apps) → changes are flexible

Main Approaches:

• 📊 predictive (waterfall) → plan everything upfront, changes are minimal
• 🔄 adaptive (agile) → flexible, frequent changes based on feedback
• 🔀 hybrid → mix of predictive and agile

How To Choose an Approach For Your Project:

• ✔️ clear requirements + stable scope → predictive
• ✔️ changing requirements → agile
• ✔️ mixed environment → hybrid

👉 bottom line: development approach is chosen based on how stable or changeable the project is.
