Two teams build the same app. One plans everything first. The other builds in small pieces.
Both ways have good and bad points.
Compare the two models, then prepare a project.
A methodology is a structured way to prepare, build and manage a project. It makes the work systematic, efficient and high in quality.
A software process model is an abstract picture of the SDLC steps.
It gives three things: predictability, efficiency and quality.
Waterfall is linear and sequential. Each phase ends before the next begins. No going back.
Phases: requirements, design, implementation, testing, deployment, maintenance.
Benefits: simple, one phase at a time, good for small projects with fixed requirements.
Limits: inflexible, weak for complex projects, risky if new needs appear.
Agile is flexible. It delivers small working parts quickly, in short cycles called iterations or sprints.
Practices: continuous integration (merge code often), test-driven development (write tests first), pair programming (two developers, one computer).
Benefits: high flexibility, happier customers. Limits: hard to scale, needs stakeholders, less predictable timeline.
The Agile circle in the book has six steps: requirements, design, development, testing, deployment, review.
Planning a project is like planning a trip. You need to know where you are going, how long it takes and what it costs.
The book shows five phases: initiation, planning, execution, performance monitoring, project closure.
Cost depends on: the team, the technology stack, project duration, risk management and quality assurance.
Risk management has four steps: identify risks, analyse them, steps to reduce them, then monitor and review.
Execution is where the team writes code and builds the software. Quality assurance uses testing, code review, stakeholder feedback and progress checks.

Q1. Book long question 2 (part): how would Agile suit a simple mobile app?
Work in short sprints. Each sprint delivers a small working part. Users give feedback often. Changes are allowed after development starts. Merge code often and write tests first.
✗ “Agile has no planning.”
✓ It plans in short cycles. Its limit is that the exact timeline and scope are harder to predict.
