UNIT–II (Agile Projects)

 

✅ UNIT–II (Agile Projects) – SIMPLE NOTES

⭐ 1. Planning for Agile Teams

Agile teams are small, flexible, self-organizing groups.

A. Scrum Team

Very simple:

  • Product Owner (PO) – decides what to build

  • Scrum Master (SM) – removes problems, supports team

  • Development Team – builds the product

👉 Remember: PO → SM → DEV

B. XP Team

XP team focuses on quality & coding practices
Members:

  • Customer

  • Developers

  • Coach

  • Tracker

  • Tester

👉 Easy trick: C–D–C–T–T

C. General Agile Teams

All normal Agile teams have:

  • 5–9 people

  • Cross-functional

  • Self-managing

  • Communicate daily

D. Team Distribution

How teams are located:

  • Co-located: in one place (BEST for Agile)

  • Distributed: team in multiple locations → needs online tools

⭐ 2. Agile Project Lifecycle (Simple Explanation)

Agile project lifecycle = build in small cycles called iterations/sprints.

Typical lifecycle:

  1. Plan – create vision, backlog

  2. Design – simple design

  3. Build – develop features in small pieces

  4. Test – test continuously

  5. Review – show to customer

  6. Improve – take feedback and improve

  7. Repeat – next iteration

👉 Trick: P–D–B–T–R–I (Plan, Design, Build, Test, Review, Improve)

⭐ 3. Phase Activities in Agile

Each iteration has:

  • Planning (what to do)

  • Development (coding)

  • Testing (continuous testing)

  • Review (show to customer)

  • Retrospective (improve team work)

⭐ 4. Product Vision (VERY SIMPLE)

Product Vision =
👉 A short statement describing what the product will achieve.

Example:
“Build a fast, secure online shopping app.”

Purpose:

  • Gives direction

  • Helps team stay focused

⭐ 5. Release Planning (MOST IMPORTANT)

Release planning = deciding what features to deliver in the next release.

Steps:

1. Create Product Backlog

Product backlog = list of all features, tasks, ideas.

Example:

  • Login

  • Payment

  • Search

  • Cart

2. User Stories

User story = a simple requirement written from user's view.

Format:
👉 “As a user, I want feature, so that benefit.”

Example:
“As a shopper, I want to add items to a cart so I can buy later.”

3. Prioritizing

Deciding which features are most important.

Methods:

  • High / Medium / Low

  • MoSCoW (Must, Should, Could, Won’t)

4. Estimating

Estimating how long each story will take.

Ways:

  • Story points

  • T-shirt size (S, M, L)

5. Creating the Release Plan

Release plan =
👉 What features will be included in the upcoming release.

Example:

  • Release 1: Login, Search

  • Release 2: Cart, Payment

⭐ 6. Monitoring and Adapting (VERY SCORING)

A. Managing Risks

Risk = a problem that might happen.

Agile reduces risk by:

  • Short iterations

  • Daily meetings

  • Frequent testing

  • Customer feedback

B. Managing Issues

Issue = a problem that already happened
Team fixes issues quickly in daily meetings.

C. Retrospectives

Retrospective =
👉 A meeting at end of iteration to improve team performance.

Team discusses:

  • What went well

  • What didn’t

  • What to improve next time

Goal: continuous improvement

🎯 Super-Short Memory Sheet (For Exam)

  • Scrum Team = PO + SM + Dev Team

  • XP Team = Customer + Developers + Coach + Tester

  • Agile Lifecycle = Plan → Build → Test → Review → Improve

  • Backlog = list of all features

  • User Story = As a user, I want…, so that…

  • Prioritizing = Must/Should/Could

  • Retrospective = improve next iteration

✅ SOLID Principles (Super Simple Meanings)

SOLID = 5 important object-oriented design principles used in Agile.

⭐ S – Single Responsibility Principle (SRP)

A class should have only one job.

👉 Meaning: One class = One purpose

⭐ O – Open/Closed Principle (OCP)

Software should be open for extension but closed for modification.

👉 Meaning: Add new features without changing old code.

⭐ L – Liskov Substitution Principle (LSP)

A child class should be usable wherever the parent class is used.

👉 Meaning: Subclasses must behave like their parents.

⭐ I – Interface Segregation Principle (ISP)

Don’t force a class to use methods it doesn’t need.

👉 Meaning: Small interfaces > Big interfaces.

⭐ D – Dependency Inversion Principle (DIP)

Depend on abstractions, not concrete classes.

👉 Meaning: High-level code should not depend on low-level code.

  ⭐ UNIT – 3 (Easy Notes + PDF References) Wireless LAN • MAC Problems • Hidden/Exposed Terminal • Near/Far • Infrastructure vs Ad-hoc • IEEE 802.11 • Mobile IP • Ad-hoc Routing I have rewritten everything in easy school-level English so you can understand quickly. 🔵 1. What is WLAN? (Wireless LAN) (Page 1 U-3 Wireless & mobile computing ) WLAN = Wireless Local Area Network. It allows devices to connect without cables using radio, infrared, or microwave signals. Why WLAN? ✔ No wires needed ✔ Quick installation ✔ Can attach to existing wired network ✔ Useful in disasters or old buildings where wiring is impossible 🔵 2. Design Goals of WLAN (Page 2–3 – Table shown in PDF U-3 Wireless & mobile computing ) ✔ Simple to use Users should easily connect. ✔ Low power use Mobile devices need long battery life. ✔ No license needed Using license-free bands reduces cost. ✔ Handle interference There is a lot of radio noise; WLAN must work even in interference. ...

UNIT–5 (Simplified & Easy Notes) Software Architecture Documentation

  UNIT–5 (Simplified & Easy Notes) Software Architecture Documentation ✅ What is Software Architecture Documentation? It explains how the software system is structured . Helps developers understand system components , modules , and design , without reading code. Works as a communication tool between architect, developer & stakeholder. ⭐ Goals of Documentation (Very Important) Knowledge Sharing Helps new developers understand the system quickly. Communication Architects share design ideas with developers. Analysis & Review Used to check if architecture meets requirements. ⭐ Two Ways to Create Architecture 1. Top-Down Approach Start from big design → break into smaller parts. Used when system requirements are clear. 2. Bottom-Up Approach Start from small components → combine to form system. Used when building systems step-by-step. ⭐ Principles of Sound Documentation (Super Important – Exam Repeated) Princ...

 Here's a breakdown of the Software Engineering Institute's (SEI) Capability Maturity Model Integration (CMMI) framework elements, particularly relevant to the Unified Process (UP) and other structured methodologies: Framework Elements: Life Cycle Phases: Inception: Focuses on establishing the project's vision, scope, business case, and feasibility. Elaboration: Defines the architecture, refines requirements, and plans the remaining project. Mitigates high-risk elements. Construction: Iteratively develops and integrates the bulk of the software, building working versions. Transition: Deploys the software to the user community and ensures operational readiness. (Note: Your request mentioned "training phase" which often aligns with Transition activities.) Artifacts of the Process: The Artifact Sets (Categories): Management Artifacts: Pertain to project planning, tracking, and control (e.g., business case, project plan, risk list). Engineering Artifacts...
