Complete Guide to Scrum

1. What is Scrum?

Scrum is an Agile framework for developing, delivering, and sustaining products in a collaborative and iterative manner.

Key Features:

2. Overview of Scrum Roles

3. Scrum Artifacts

  1. Product Backlog: Ordered list of all desired work on the product.
  2. Sprint Backlog: Subset of the Product Backlog selected for a Sprint, along with a plan to deliver it.
  3. Increment: A working product slice delivered at the end of the Sprint.

4. Scrum Events

  1. Sprint Planning: Define the Sprint Goal and determine what will be delivered during the Sprint.
  2. Daily Scrum: 15-minute meeting to inspect progress and adapt plans.
  3. Sprint Review: Demonstrate the Increment and gather feedback.
  4. Sprint Retrospective: Reflect on the Sprint and identify improvements.

5. Practical Example: Developing a Library Management System

Step 1: Define the Vision

Vision: Create a Library Management System that allows users to search for books, borrow them, and manage returns.

Step 2: Create the Product Backlog

ID Feature User Story
1 Search for books As a user, I want to search for books by title or author so that I can quickly find a specific book.
2 Borrow books As a user, I want to borrow available books so that I can read them.
3 Return books As a user, I want to return borrowed books so that others can access them.
4 View borrowing history As a user, I want to see my borrowing history so that I can keep track of the books I borrowed.

Step 3: Plan the Sprint

Sprint Goal:

Enable users to search for books and borrow them.

Selected Backlog Items:

  • Search for books
  • Borrow books

Task Breakdown:

  • Design search interface
  • Implement search functionality
  • Create database for book inventory
  • Develop borrowing functionality

Step 4: Execute the Sprint

Daily Scrum:

Each day, team members discuss:

  • What they completed yesterday
  • What they will work on today
  • Any blockers or issues

Development:

Implement the features using tools such as Java (backend), MySQL (database), and React (frontend).

Step 5: Sprint Review

Demonstration:

Show the working features (book search and borrowing functionality) to stakeholders.

Feedback:

Gather suggestions for improving the search algorithm or user interface.

Step 6: Sprint Retrospective

Reflect on:

  • What went well? (e.g., effective team collaboration)
  • What didn't go well? (e.g., delay in database setup)
  • What can be improved? (e.g., allocate more time for testing)

Action Plan:

Assign a dedicated tester to improve quality in the next Sprint.

Step 7: Repeat the Process

Plan the next Sprint to include:

  • Implementing book return functionality
  • Viewing borrowing history

Continue iterating until the product is complete.
