Explicit Process Rules in Kanban: Organizing, Owning, and Continuously Improving Workflow Rules

The article introduces the second practice of the Kanban method – making process rules explicit – which is essential yet often underestimated, affecting the overall effectiveness of Kanban implementation.

Team operations rely on various rules such as demand entry criteria, prioritization, handling emergencies, quality standards before testing, and scheduling frequency. Making these rules explicit provides clear decision criteria, requiring shared understanding and commitment from all team members.

4.1 Organize and Clarify Process Rules

Process rules are categorized into three types: (1) Value‑flow rules that define standards for moving work items between stages; (2) Rules related to periodic events like planning meetings; (3) Other collaboration rules covering daily practices.

4.1.1 Explicit Value‑Flow Rules

Value‑flow rules are linked to the visualized value stream. Examples include the criteria for a demand to enter analysis, become ready, be coded, move to testing, be accepted, and be released. The article shows how a team defines a “Definition of Ready” by discussing business, dependency, and technical risks, and by ensuring work is small enough for thorough discussion.

4.1.2 Explicit Rules for Periodic Events

Typical periodic events in Kanban include daily stand‑ups, ready‑queue filling meetings, release planning, and improvement activities. Teams must define the frequency, format, selection criteria, and exception handling for each event, ensuring everyone shares the same expectations.

4.1.3 Explicit Other Collaboration Rules

Remaining rules cover daily collaboration such as board update policies, work‑in‑progress limits, measurement and feedback mechanisms, and improvement action tracking. Teams should start with the most impactful rules and refine them over time based on feedback.

4.2 Team Ownership of Rules

Explicit rules become alive only when the team adopts and applies them autonomously. Examples include selecting the next ready demand without external assignment or prioritizing bug fixes during stand‑ups. Shared ownership empowers self‑organization and embeds quality into the workflow.

4.3 Continuous Improvement of Rules

Process rules are not static; they evolve as the environment and team maturity change. Explicit rules serve as a baseline for objective, rational improvement discussions, preventing subjective blame. Improvements must be codified back into the rules to create a new, reliable baseline.

Summary

Explicit process rules are the natural extension of visualizing value flow; they form the DNA of team behavior, must be organized, collectively owned, and continuously refined to maintain adaptability and built‑in quality.
