Alright, let’s talk about Kanban vs. Scrum because deciding how to organize work can be as overwhelming as choosing a coffee at a fancy café. Do you go for a structured, predictable system like following a detailed recipe for a caramel macchiato (Scrum), or do you prefer a more adaptable approach like a barista adjusting a pour-over based on the grind and water temperature (Kanban)? Both are great, but picking the right one depends on how your team works best. And just like coffee, your team’s preferences may change over time, meaning the best approach today might not be the best approach six months from now.
What is Kanban?
Kanban is an approach that helps teams manage work visually. Think of it as running a café where orders come in unpredictably, and baristas handle them as efficiently as possible while making sure no one gets overloaded. Instead of rigid schedules, the team keeps things moving by focusing on what’s most important at any given moment.
How Kanban Works
Visual Boards: Tasks are displayed on a board, similar to a coffee shop menu where baristas see all pending drink orders.
Work-in-Progress Limits: No overloading. Just as a barista can only make a few drinks at a time before quality suffers, teams focus on a set number of tasks at once.
No Fixed Timeframes: Work is completed as soon as it’s ready, much like when customers pick up their drinks instead of waiting for a full batch to be finished.
Adjustable Process: Teams tweak their workflow as needed, just as a coffee shop might adjust their menu based on demand.
Pull System: New work starts only when space is available, keeping everything in balance. A barista doesn’t start making a drink until they’ve finished the previous one.
Better Efficiency: By reducing delays and optimizing workflow, teams can improve productivity. Like a well-organized café, everything moves smoothly, and customers (stakeholders) stay happy.
Pros of Kanban
Provides continuous progress rather than waiting for fixed cycles.
Helps teams visualize workflow and identify where bottlenecks occur.
Works well in environments where priorities change frequently, just like a café adjusting to rush hour.
Great for teams managing incoming requests or support tasks.
Cons of Kanban
Without clear limits, teams might take on too much at once, leading to inefficiencies.
Doesn’t provide built-in time frames, which can make long-term planning harder.
Measuring long-term progress can be tricky compared to structured methods.
What is Scrum?
Scrum is a structured approach where work is divided into short cycles called sprints, usually lasting between one and four weeks. Imagine running a coffee shop where every shift is planned in advance: the team knows exactly what drinks will be made, who’s responsible for what, and when each order will be completed.
How Scrum Works
Sprints: Work is planned and completed in short, predictable cycles, like a pre-scheduled coffee brewing shift.
Clear Roles: Just as a coffee shop has a manager, baristas, and cashiers, Scrum has defined roles: the Scrum Master (keeps things running smoothly), Product Owner (prioritizes work), and Development Team (does the actual work).
Daily Meetings: Quick check-ins ensure everyone knows what’s happening, much like a morning huddle before the café doors open.
Goals for Each Sprint: The team commits to achieving a goal within the Sprint, but the specific tasks to reach that goal can be adjusted as needed, similar to how a café might set a goal to serve 100 drinks in a shift.
Step-by-Step Progress: Instead of launching a huge project all at once, Scrum teams build their product piece by piece, refining it along the way.
Review and Improve: After each Sprint, teams analyze what worked well and what didn’t, just as a café might adjust processes after a busy weekend.
Pros of Scrum
Provides structure and clear deadlines.
Encourages regular feedback and improvements.
Helps teams stay aligned with business goals.
Works well for teams building new products or features.
Cons of Scrum
Less flexibility if priorities change mid-Sprint.
Requires commitment to Sprint deadlines, which can sometimes be rigid.
Meetings and planning sessions take time, which can feel excessive.
Kanban vs. Scrum: Key Differences
Feature | Kanban (Dynamic Coffee Bar) | Scrum (Structured Coffee Shop) |
Work Style | Continuous flow, work as needed | Planned cycles (Sprints) |
Roles | No set roles | Clearly defined roles |
Planning | Ongoing, task-by-task | Planned at the start of a Sprint |
Work Limits | Limits on work in progress | Sprint backlog defines work scope |
Delivery | Tasks completed individually | Work delivered at the end of each Sprint |
Flexibility | Very flexible | Moderately flexible |
Meetings | Few, as needed | Frequent, structured meetings |
Best For | Teams with shifting priorities | Teams needing structure and predictability |
When to Use Kanban
Kanban is best when:
Work arrives unpredictably, like coffee orders during peak hours.
Teams need flexibility and prefer adjusting work as they go.
There’s no need for strict roles—everyone works together as needed.
Continuous delivery is better than waiting for everything to be finished at once.
The team environment is more like a dynamic coffee shop rather than a structured production line.
When to Use Scrum
Scrum is a better choice when:
Work requires clear structure and step-by-step planning.
Teams need well-defined roles to stay organized.
Goals require a predictable process with set deadlines.
Regular check-ins help the team refine how they work.
The work environment is more like a highly structured café where consistency is key.
Can You Mix Kanban and Scrum? (Scrumban)
Yes! Some teams use Scrumban, which combines Scrum’s structure with Kanban’s flexibility. Think of it as a café where there’s a structured menu, but customers can customize their drinks. Teams can use Kanban boards to track work while still operating in time-boxed Sprints. This method allows for more flexibility without completely losing structure.
Final Thoughts
Both Kanban and Scrum have their strengths, just like different coffee-making styles. Kanban is great for teams that need flexibility and adapt frequently, while Scrum works well for teams that require clear goals and a structured process. If you’re unsure, try both and see which one fits your team’s needs best. Or mix them together, sometimes, the best coffee comes from a little experimentation.
