What is Kanban?
Kanban means “billboard” or “sign” in Japanese. Originally developed as a way for Toyota to optimize their assembly line flow it has since been used for numerous other industries and even in your personal life as a form of organization.
Getting started is pretty easy.
First assemble the following items:
Sticky Notes (all same color is fine)
Dry Erase Markers
Start by visualizing your workflow. This is one of the essential keys of Kanban.
Think about how you do a project, clean the house, or get tasks done. Then split your whiteboard into those sections with your markers based on that flow. Someone on twitter said “I’ve never done the same Kanban twice”. This is because it’s not rigid but extremely malleable. You grow with Kanban, not into it.
My Kanban at work consists of 4 columns (Ready, Doing Today, Doing, Done), but yours can be anything you want and named anything you want. There is no “wrong way”. For the sake of this post let start off with the simplest form – Ready, Doing, Done.
Now it’s time to pull all that psychic weight out of your head. Take your pen and put each task you want to get done on separate sticky notes. No need to go into detail, you can always revisit these and break them into more notes. So you might write down “take the car to the mechanic”, “call the landlord”, “finish the report”, or “push changes to source control”. Write out everything you can think of to accomplish your long-term or daily goal.
Once you’ve unloaded it’s time to put them on the board. The way I do this is to actually stick them off the board first in my “Backlog”. This is the area that I keep when I have new things to add. I also am constantly re-prioritizing this and the “Ready” area with new and existing tasks.
Limiting Your “WIP”
WIP stands for Work in Progress. This is the other essential key of Kanban. Limit your work in progress.
To do this you will set limits of how many items (or notes) can be in your Doing or To Do columns at one time. Think of a juggler. A good juggler can handle juggling two items, or maybe three. Only really good jugglers can handle 4 or 5.
The key to Kanban success is to find your limits. Start off small and then work up. Think about what your limit is and why. It may surprise you that your limits can change based on the project or even mid-project. It’s ok, adjust these limits as you see fit. Mine in the photo below have a limit of 1 item WIP.
Visualize a supermarket and how they stock their shelves. The customers at the end of the chain “pulling” these items. The process by which the store keeps shelves stocked is only by what gives the best profit/success and, ultimately, what is being “pulled” downstream.
Prioritize in you Backlog, move the tasks into Ready, to Doing, then Done. Watch how your WIP changes and how items flow. Tweak it where it fits your process and work flow best. This is your Kaizen or “improvement”.
Visualize your flow. Limit Your WIP. You are now ready to Kanban.

If you’re thinking about following me on Twitter:
I don’t always tweet about “X technology”. Although a big part of my life is computers, programming, SQL server, and other technology I don’t always tweet about it. I try to keep a good mix and at any given time I tweet about life, family, or just something I find absolutely hilarious (I hope you do too).
I go to conferences and tweet about them. I am a fairly active member of the SQL Server community as well as the .NET community. With that I regularly attend conferences and events and tweet about them. I know for some this may get old really quick on a Saturday afternoon. All I can say is they usually only last a few hours
My intention is never to offend. I usually try to keep twitter light and outside of the political or religious arena.
My opinions are not my employer’s. ‘Nuff said
Why I don’t follow you. Occasionally I will go through my follower list and see what others are talking about. If I see you tweeting about something that interests me I will most likely follow back. Please don’t be offended if I don’t follow right away or never follow. It could be that the timing is just wrong.
Other reasons I might not follow you:
- You seem like a spammer. Please put up a picture, stop re-tweeting news links all the time, make yourself as “real” as possible. I want to hear from you, not the latest Apple news that’s already been re-tweeted 1,000 times.
- You’re constantly negative. The world is negative. I even get negative sometimes. It happens. Given the choice I don’t prefer to see it on twitter.
- You rarely tweet. Tweet regularly and I will remain your faithful follower.
Why I do follow you
- You have some great things to say
- You’re funny. If you make me laugh. Well. Then I thank you for that.
- We’ve met in real life. Usually an instant follow.
- We’ve shared a great discussion. Of course I will follow you.
