Scrum & Kanban for Product Managers

As a Product Manager, you are a key player in your team's Agile process. The framework your team uses will define the "ceremonies" (meetings) you participate in, the "artifacts" (documents) you are responsible for, and the overall rhythm of your work. Understanding the nuances of Scrum and Kanban allows you to work more effectively with your development team, manage stakeholder expectations, and ensure a smooth flow of value from idea to customer. You are not just a user of the system; you are a co-owner of its success.

Comparing Scrum and Kanban:

• Scrum: A prescriptive framework with specific roles, events, and artifacts.

  Key Concepts:

  • Roles: Product Owner (that's you!), Scrum Master, and Development Team.
  • Sprints: Work is done in fixed-length iterations (e.g., 2 weeks). A potentially shippable increment of the product is delivered at the end of each sprint.
  • Artifacts:
    • Product Backlog: The master list of everything that needs to be built, ordered by priority. The PM owns this.
    • Sprint Backlog: The list of items from the Product Backlog that the team commits to completing in the current sprint.
  • Ceremonies (Events):
    • Sprint Planning: At the start of a sprint, the team selects work from the Product Backlog.
    • Daily Scrum (Stand-up): A short daily meeting for the team to sync up.
    • Sprint Review: At the end of the sprint, the team demos what they built.
    • Sprint Retrospective: After the Review, the team discusses how to improve its process.

  PM's Role in Scrum: You are the Product Owner. You are responsible for maximizing the value of the product by creating, prioritizing, and managing the Product Backlog. You are the final arbiter of what the team works on.

• Kanban: A visual workflow management method that focuses on continuous delivery and limiting work in progress.

  Key Concepts:

  • Visual Board: Work is visualized on a Kanban board with columns representing stages of the workflow (e.g., To Do, In Progress, In Review, Done).
  • Continuous Flow: There are no prescribed sprints. Work items are pulled into the workflow as the team has capacity. The focus is on a smooth, continuous flow of work.
  • Work in Progress (WIP) Limits: Each column on the board has a limit on how many items can be in it at one time. This prevents bottlenecks and forces the team to focus on finishing work before starting new work.
  • Metrics: Kanban teams focus on metrics like Lead Time (how long it takes from request to delivery) and Cycle Time (how long it takes from the start of work to delivery).

  PM's Role in Kanban: Your role is less formally defined than in Scrum but is just as crucial. You are still responsible for ensuring the team is working on the most valuable items. This means continuously prioritizing the "To Do" column and collaborating with the team to ensure work flows smoothly through the system.

Tools & Recommended Resources:

• Jira: The industry standard. It has powerful, dedicated templates for both Scrum (sprints, backlogs) and Kanban (boards, WIP limits).
• Trello / Asana: Simpler, more user-friendly tools that are great for Kanban boards and less formal Agile processes.
• Linear: A modern, opinionated tool that is gaining popularity for its speed and keyboard-driven workflow, often used by teams that practice a hybrid of Scrum and Kanban.

Example in Action: Scrum vs. Kanban for a Support Team

Scrum: A support engineering team using Scrum might plan a 2-week sprint to fix a set of 10 known bugs. They commit to these 10 bugs and work on nothing else. This is great for planned work but bad if an urgent, critical bug appears mid-sprint.

Kanban: The same team using Kanban would have a backlog of bugs. They would pull the highest-priority bug and work on it. Once finished, they would pull the next one. There are no sprints. If an urgent, critical bug appears, it can be put at the top of the backlog and be the very next thing the team works on. This makes Kanban very well-suited for teams that need to react to unpredictable, incoming work, like support and operations teams.
