Kanban

Toyota Production System“The two pillars of the Toyota

production system are just-in-time and automation with a human touch, or autonomation. The tool

used to operate the system is kanban.”

Taiichi Ohno, Toyota Production System (adopted 1962)

Throughput

Teamwork

• Enhances Teamwork– Team focus on goals that add

value not individual tasks• Encourages Swarming

When Blocked…

• Lower priority work…– Spikes– Analysis

• Production Capability Improvement work…– Tool Automation– Refactoring– Personal Development– Innovation

• But NOT– Anything which will create

work downstream

NOTE: This doesn’t mean you should ONLY “sharpen the knife” when Blocked!!!

When should I use Kanban?Extend Scrum to the whole

value stream– Upstream - Manage the

Backlog process - All the steps preceding the actual development sprints

– Downstream – Manage system testing, packaging, deployment

When should I use Kanban?

• During hardening sprints• For the support/helpdesk teams/activities• For periods of heavy R&D

When should I use Kanban?

• Another angle to start your transition from– Add visibility and WIP controls to current

workflow– Inspect the constraints/bottelenecks– Adapt the workflow, resources, processes – Scrum

It if it makes sense!– Drive for maximum throughput and fastest time to

delivery– Repeat
