For Kanban to be effective, the team needs to visualize the workflow. This involves breaking down the process into distinctive steps and tracking the flow of work going through them on a Kanban Board. Kanban Boards act as information radiators that clearly communicate the status of the current work to the entire team, fostering communication and team collaboration.
It doesn’t benefit anyone to have lots of work in progress but not to accomplish anything at the end of the day. Kanban allows one to control the work in progress to ensure the maximum flow of an item from start to finish, from the idea into the hands of the customer.
You can’t manage what you don’t measure. Kanban focuses on ensuring a smooth and high flow of work, and it also gives you the tools to measure it and identify bottlenecks.
There is a known principle in project management that quality should be built into the process and not later inspected into. You can reduce defects and improve the flow of work by ensuring that process policies are explicit and known to everyone.
Once you make the policies explicit and continuously measure the performance of your workflow, you can focus on identifying bottlenecks and introducing gradual improvements to the whole process. Kanban leverages a number of scientific models, such as the Theory of Constraints, which teaches us how to identify the constraint and then elevate or exploit it.
