Scrum Framework, Scrum Artifacts, Meetings, Roles, Sprint Planning, Burndown Chart and Scrum Case Study

Unit 3

๐ŸŽฏ Unit 3 Overview

Unit 3 focuses on Scrum. Scrum is an Agile framework used to develop software in short iterations called sprints. This unit covers Scrum framework, artifacts, meetings, activities, roles, sprint planning, daily scrum, sprint review, retrospective, user stories, acceptance tests, burndown chart and Scrum case study.

Exam Tip: Scrum framework, Scrum roles, Scrum artifacts, sprint planning, daily scrum and burndown chart are highly important for RGPV exams.

๐Ÿ“˜ Introduction to Scrum

Scrum is an Agile framework used for managing complex software projects. It divides development work into small time-boxed iterations known as sprints.

Features of Scrum

๐Ÿ—๏ธ Agile Scrum Framework

Scrum framework consists of roles, artifacts and events that help teams deliver software incrementally.

Scrum Element Includes
Roles Product Owner, Scrum Master, Development Team
Artifacts Product Backlog, Sprint Backlog, Increment
Events Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective

๐Ÿ‘ฅ Scrum Roles

Product Owner

Responsible for product vision, product backlog, priority and business value.

Scrum Master

Helps the team follow Scrum, removes blockers and supports continuous improvement.

Development Team

Cross-functional team that designs, develops, tests and delivers working software.

๐Ÿ“ฆ Scrum Artifacts

1. Product Backlog

Product backlog is a prioritized list of all features, requirements, bug fixes and improvements needed in the product.

2. Sprint Backlog

Sprint backlog contains selected product backlog items that the team commits to complete in a sprint.

3. Increment

Increment is the working software produced at the end of a sprint.

๐Ÿ—“๏ธ Scrum Meetings / Events

Meeting Purpose
Sprint Planning Select work for the sprint and define sprint goal.
Daily Scrum Short daily meeting to discuss progress, plan and blockers.
Sprint Review Demonstrate completed work and collect feedback.
Sprint Retrospective Discuss what went well, what went wrong and improvements.

โš™๏ธ Scrum Activities

  1. Create product vision.
  2. Prepare product backlog.
  3. Prioritize backlog items.
  4. Plan sprint.
  5. Execute sprint.
  6. Conduct daily scrum meetings.
  7. Review completed work.
  8. Conduct retrospective.
  9. Deliver product increment.

๐Ÿงช Scrum Team Simulation

Scrum team simulation means practicing Scrum process in a project-like environment. It helps students understand team roles, sprint planning, backlog handling and sprint review.

Example Simulation

๐Ÿ“ Scrum Planning Principles

๐ŸŽฏ Product and Release Planning

Product Planning

Product planning defines product vision, goals, features and roadmap.

Release Planning

Release planning decides which features will be delivered in a particular release and when.

Product planning gives long-term direction, release planning decides delivery schedule.

๐Ÿƒ Sprinting: Planning, Execution, Review and Retrospective

Sprint Planning

Team selects user stories from product backlog and creates sprint backlog.

Sprint Execution

Team develops, tests and integrates selected work during sprint.

Sprint Review

Team demonstrates completed work to stakeholders and receives feedback.

Sprint Retrospective

Team discusses improvements for next sprint.

๐Ÿงพ User Story Definition and Characteristics

User story is a short requirement written from the user's point of view.

As a [user], I want [feature], so that [benefit].

Characteristics of Good User Story

โœ… Acceptance Tests and Verifying Stories

Acceptance tests define conditions that must be satisfied for a user story to be considered complete.

Example

User Story: As a student, I want to download PDF notes.

๐Ÿ“‰ Burndown Chart

Burndown chart is a graphical representation showing remaining work in a sprint over time. It helps track progress and predict whether sprint work will be completed on time.

Uses

๐ŸŒ… Daily Scrum

Daily Scrum is a short daily meeting, usually 15 minutes, where team members discuss progress and blockers.

Three Common Questions

๐Ÿ“Œ Scrum Case Study

Suppose a team is developing an online RGPV notes website.

  1. Product Owner creates backlog: homepage, semester page, subject page, PDF download page.
  2. Team selects homepage and subject page for Sprint 1.
  3. Daily scrum is conducted to track progress.
  4. At sprint review, working pages are shown to stakeholders.
  5. In retrospective, team decides to improve mobile responsiveness.

โš–๏ธ Product Backlog vs Sprint Backlog

Product Backlog Sprint Backlog
Complete list of product requirements. Selected work for current sprint.
Managed by Product Owner. Managed by Development Team.
Continuously updated. Fixed during sprint as per sprint goal.
Long-term product work. Short-term sprint work.
