Introduction & Learning Objectives

Learning Objectives Define Agile methodology and contrast it with traditional project management. Explain the purpose of key Agile concepts like Sprints, User Stories, and Backlogs. Identify the core responsibilities of roles like Product Owner and Scrum Master. Create a simple user story for a given project feature. Outline the steps for planning a short project using an Agile approach. Describe the importance of iterative development and customer feedback in the Agile process. Have you ever started a big school project and realized halfway through that you needed to change your plan? 🤔 What if there was a way to build projects that welcomes change? In this lesson, you'll learn about Agile, a popular and modern way to manage computer science projects. We'll expl...

Key Concepts & Vocabulary

TermDefinitionExample AgileA flexible approach to project management that focuses on breaking large projects into small, manageable tasks and delivering work in short cycles.Instead of building an entire video game in one year, an Agile team might build one playable level in two weeks to get feedback from players. SprintA short, time-boxed period (usually 1-4 weeks) during which a team works to complete a set amount of work.A team building a social media app might have a 2-week sprint focused only on creating the user login and profile page. User StoryA simple, plain-language explanation of a feature written from the perspective of the end-user. It follows the format: 'As a [type of user], I want [some goal] so that [some reason].'For a school library app: 'As a student, I...

Core Syntax & Patterns

Iterative Development Plan -> Build -> Test -> Review -> Repeat This is the core cycle of Agile. Instead of building the entire project at once, you build and release small, working pieces. Each cycle (or iteration) adds more features and improves the product based on feedback. Timeboxing Fix the time, flex the scope. Use this to maintain a predictable rhythm. Sprints have a fixed length (e.g., 2 weeks). The team commits to completing a certain amount of work in that time. If they can't finish everything, the unfinished work is moved to the next sprint, rather than extending the current one. User Story Format As a <user role>, I want <goal> so that <benefit>. Use this pattern to ensure every feature is focused on providing value to...

Sample Practice Questions

Challenging
After the first sprint for the 'To-Do List' app, user feedback indicates the 'Add Task' button is too small. How would an Agile team most likely respond?
A.Ignore the feedback because the feature is already 'done'.
B.Start a new, separate project just to fix the button.
C.Create a new user story or task for fixing the button, add it to the Product Backlog, and prioritize it for an upcoming sprint.
D.Tell the user that the design cannot be changed.
Challenging
A team consistently skips their Sprint Retrospective meeting to 'save time' for more coding. According to the tutorial, what is the most significant long-term risk of this behavior?
A.The team will not learn from their mistakes and their process problems (like poor estimation or communication) will never be fixed.
B.The Product Owner will not know what the team is working on.
C.The project will be cancelled immediately.
D.The team will have to write more documentation to make up for the missed meeting.
Challenging
A team has the following user story: 'As a user, I want a profile page.' What is the most critical piece of information missing from this story, based on the standard format?
A.The specific type of user (e.g., student, teacher, parent).
B.The technical details of how to build the page.
C.The deadline for when the page needs to be completed.
D.The 'so that' clause explaining the benefit or reason for the feature.
