To Team or not to Team?
If you look at the definition of Kanban or Lean, you wouldn’t find teams anywhere there.
If you look at the Agile Manifesto, you can find “The best architectures, requirements, and designs
emerge from self-organizing teams”
Scrum is quite clear about the topic (Quoting the Scrum Guide 2011)
"Scrum Teams are self-organizing and cross-functional. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team. Cross-functional teams have all competencies needed to accomplish the work without depending on others not part of the team. The team model in Scrum is designed to optimize flexibility, creativity, and productivity."
So, if you are a manager of an organization on the Kanban train of evolutionary improvement, what does it mean for team structure? Should you keep the current structure? Adopt the Scrum Feature Teams concept? Do something else altogether? How should you organize your people to be as effective as possible in delivering value for the stakeholders?
Teams as an emerging property?
I personally believe that even if kanban the tool doesn’t talk about teams (obviously since it’s just a visualization and process-driving tool), despite the fact that the Kanban Method for evolutionary change doesn’t talk about teams (obviously since it starts from where you are, respecting your current structure, letting changes be pulled from actual need), more effective patterns for team formation will emerge when Kanban is really used.
At their core, Teams affect communication bandwidth. They partition the organization to enable increased communication bandwidth among people in a team, while counting on the fact that communication bandwidth to people outside the teams is not that important. Since we are talking about people, not network nodes, teams also allow the communication bandwidth to increase, the longer the team is working together, due to the team formation model. I recently read “The Talent Code” where the behaviour of our brain around learning new skills using myelin to wrap neurons to increase bandwidth reminded me of how teams behave.
So it seems like teams can really increase our effectiveness, and everyone in a reasonably sized organization cannot even bear to think about getting rid of the partitioning, right?
Well some of the Kanban thinking says that since Kanban massively reduces coordination costs via hyper-visualization and the pull system, the size of teams can increase significantly. Since we advocate using classes of service to allocate capacity to demand, thereby maintaining flexibility, we shouldn’t allocate people to demand.
The main reason not to go to teams is that teams might be local optimization. If our workload/demand was certain, and the uncertainty as to what effort/speciality is needed to deliver it was low, we could build the teams that optimize our performance. If that workload/demand didn’t vary over time, we could maintain the same teams and still have optimal effectiveness. But since in most environments we are facing a complex system with uncertainty/variability in the workload/demand, as well as the implementation effort/speciality required, it seems like sustaining stable teams will cost us in some optimization.
In my recent conference talks (GOTOCPH, LKBE11, LKCE11) I provided my view on this question of team formation and Kanban. I described the following progression:
- Functional/Component Teams based on specialization
- Teams On-Demand – whenever pulling a new Feature for work, associate the relevant people with it. They will deliver that feature, and after a few weeks return to their home teams. This approach provides lots of flexibility, but typically has relatively high coordination costs. It also doesn’t really benefit from the improved communication bandwidth among the team members that you get from persistent teams. This is very similar to the Feature Driven Development team mode by the way.
- Project/Initiative Teams – whenever pulling a new Project/Initiative for work, associate the relevant people with it. They will work together as a virtual team for the duration of that project/initiative, and after a few months, return to their home teams. The benefits of this approach is lower coordination costs as the teams don’t change that often. In addition the people working towards the same business goal are working together. The communication bandwidth increases as well over time, as well as the feeling of purpose and alignment. On the other hand, flexibility goes down. It is harder to shift people into projects/initiatives. It is harder to shift people out. If there is significant variability in the specialization required along the life-cycle of the project, selecting the right team becomes hard. If you work on versatility of your people, or already have a great group of generalizing specialists, this will be less of a problem. It can also be addressed by keeping a slack of several people working outside of project/initiative teams, that can be easily shifted in and out of activities on demand. It makes even more sense if those people are your experts/heroes. I’m seeing this mode in action in several organizations.
- Teams pull work – The next mode is where you create stable work cells that are able to handle almost everything you throw at them. These work cells stay together as the main organizational unit, and pull work based on the next business option the organization wants to exercise, regardless whether it is to accelerate an existing initiative or start something new. Here the communication bandwidth grows stronger and stronger. The flexibility and agility to shift business priorities and help swarm to work in process remains quite high, but the internal team flexibility remains an issue. The same slack of people not associated to teams can help here as well. I’ve seen this specific mode in action in several organization, and it works great, assuming you are ready for the change.
- On demand teams – Wait, didn’t I mention this one? Yes, I did. The difference here is that assuming you somehow have a tightly knit group which already managed to create lots of communication bandwidths among the WHOLE group, you can have a win-win. Total flexibility and global optimization. This should be the holy grail of any manager of about 20-40 people I would imagine. A force to reckon with…
Mixing it up
You don’t have to decide on one model. Not all work is created equal, so not all teams should follow the same structure. Some interesting examples:
- 80% on-demand, 20% focused on an initiative
- 80% on-demand, 20% cross-functional work cell (A-Team)
- 80% project teams, 20% on-demand able to swarm to a team in distress and help, or join a team to teach them some new skill as appropriate.
Some organizations will jump in, create work cell teams, and start working. I’ve seen it in action, and when you REALLY have enough energy in the organization to make this maneuver, by all means go for it.
Other cases you will not have enough energy. Or you will THINK you have enough energy, but reality will hit you in the face when all the middle managers / team leads that led you to believe they are on-board are not that supportive once it is time for action and for supporting the actual new structure.
So think hard about what is your case. And if you want to go for a more evolutionary change mode, consider the following:
- Start with on-demand teams
- Pilot one initiative/project team – especially useful when you have a risky initiative with a lot of uncertainty and dependencies, that is mission critical. Assign the success of this team structure to one of your best and most trusted people, if not yourself. Whether he is the Coach, the actual Lead, or something else is secondary. The important thing is that he will be in charge of making the team structure work, and together with the team make the learning from that available to the rest of the organization
- Move to more and more initiative teams as necessary
- When a project/initiative finishes consider turning the team to a work cell to pull more features in that area, or more features in general
- Ideally, teams will have the capabilities to take almost all work on. If not, use a talent matrix showing what teams can do what and gaps to invest in. As well as talent matrix inside a team that will help teams grow some internal versatility (note not everyone on a team needs to know everything at the same level)
When creating teams be careful not to spread yourself too thin. If you have too many small teams it might be an indication you are not managing flow effectively at the Initiatives/activities level. I love teams of 4-5 people by the way.
If you find many people need to be on many teams, you have a real problem. It is ok for a minority of the people, especially specialists, to be needed by many teams. Maybe they should stay as auxiliary on-demand, while spending some of their capacity offloading knowledge to the teams. But if it’s not a minority, then you really need to work on versatility, or the on-demand might be a better fit. The whole point of the teams is to create the communication bandwidth. Without that, they’re just overhead.
I presented a couple of team modes here, as well as one way you can use them. This is really context-specific stuff, so I cannot tell what will work for your case. But I hope the modes help you relate the Lean/Kanban effectiveness principles to the options of team formation. In upcoming posts I will try to relate this to a couple of thinking frameworks I grew fond of lately (RightShifting? Cynefin?)
Thanks for this, I have two teams which fit different profiles. The one that works best is 4 people plus myself, and they are all partially allocated to other teams too. That can make things difficult, and I’m considering if we should include all their work on the team kanban, even if it’s for other projects. I’m leaning that way.

Yes I would certainly try to visualize and limit WIP everything including work/services provided to other teams. Exactly how really depends on the specific context…
A topic of interest to me, especially in the context of FlowChain. FlowChain suggests a team-on-demand model for allocation of folks to work.
BTW What’s the difference (in your mind) between your team modes 2 and 5?
– Bob @FlowchainSensei
P.S. Thanks for the #Rightshifting mention 🙂
I will look at flow chain of course…
U recently help add to my options for reading/exploring 😉
Regarding 2 and 5 I see 2 as a poor mans teams on demand with low effectiveness. 5 is the ideal on demand, done on the basis of strong organizational social connections.
I would equate 2 with the analytic mindset and 5 with maybe even chaordic. I have a draft blog post elaborating a bit more about the rightshifting link. ETA Tuesday…
Good blog 🙂
In our project, we use a team mode which has 80% feature team and 20% on demand members. The feature team is like a work cell (3 to 5 team members) and focus only on pulling work from their swim lanes. The on-demand members are specialists who switches across swim lanes.
I have one point about the mode where 80% of your team is on-demand members. Dont you think it would create more queues in your flow since the on-demand members would be switching across lanes and their availability at any point of time may not be very certain?
Hi Rajith, thank you for your interesting comment.
To clarify, in the 80% on demand most people are still allocated to a feature lane while working on the feature. After the feature is complete they are free to stay as the work crew and pull another feature or move to another lane.
Still, I fear that you are right and more queues will accumulate as people will free up in different times so the new crew might be blocked until all people free up. Or the crew will start without all te people it needs ( which I fear might be worse)
OTOH this is very similar to the approach in FDD so maybe there is a way to reduce this queueing without very expensive coordination. Will try to get David anderson to comment…

How do you scale a tech team using Kanban?…
Another option is to go for a hybrid approach. Since the backlog has component driven work as well as cross functional work I would consider creating both component driven teams and cross functional feature teams. E.g. Server team, front end team, cros…
[…] This is why “Managers Kanban” is just a temporary “Training” pattern on the way to full flow pull mode. You can consider it a kind of “Concierge MVP” – the goal here is learning about what works and is viable as a flow model. It is not a viable long-term model of managing the work. It considers the main risk of going lean/agile being the ability of the managers to think lean/agile, think flow, act according to lean/agile decision filters. When this risk is off the table, it is time to go to the next stage which is sustainable lean/agile involving the individuals with managers supporting but not necessarily involved day-to-day in the flow of work throughout the organization. The classic next step is to create stable Product Stream/Project/Feature teams that will be able to work together with Product Management on a specific value stream. These can be cross-functional, functional teams or a mix depending on the kind of work the organization is facing. Read more about those teaming options in an earlier blog post of mine. […]
