Flow Master

A team coach who facilitates service request flow in a Kanban or continuous flow system; essentially the Scrum Master for flow-based work.

Key Points

  • Servant leader focused on smooth flow, removing blockers, and fostering continuous improvement.
  • Guides visualization of work, setting and refining WIP limits, and using explicit process policies and classes of service.
  • Teaches and uses flow metrics such as lead time, cycle time, throughput, and work item age to drive decisions.
  • Collaborates with the Service Request Manager and stakeholders to balance demand with capacity and improve delivery predictability.

Example

A marketing operations team uses Kanban. The Flow Master notices growing queues before design review and rising work item age. They facilitate a discussion to lower WIP limits, add a triage step, and clarify pull policies. Over the next two sprints worth of time, lead time drops and throughput stabilizes.

PMP Example Question

In a Kanban team experiencing frequent blockers and rising work item age, who should coach the team to adjust WIP limits, refine pull policies, and facilitate daily flow reviews?

  1. Flow Master
  2. Product Owner
  3. Sponsor
  4. Functional Manager

Correct Answer: A — Flow Master

Explanation: The Flow Master serves as the team coach for Kanban, similar to a Scrum Master, and leads practices that improve flow and remove impediments.

ICS/OT Cybersecurity Fundamentals — Security Built for Industrial Systems

Industrial control systems cannot be secured like ordinary IT. A forced reboot, aggressive scan, or incompatible patch can interrupt production and create real safety consequences. Effective OT security begins with understanding the systems, constraints, and risks unique to industrial environments.

This course gives IT professionals, engineers, operators, and security practitioners a practical foundation in ICS threats, zone and conduit design, risk assessment, passive asset visibility, and vendor evaluation. You will learn how IEC 62443, NIST CSF, and MITRE ATT&CK for ICS apply where availability and safety come first.

Eight reconstructed incidents—including Stuxnet, Triton, Ukraine 2015, Colonial Pipeline, and PIPEDREAM—show how attackers move through OT environments, what they target, and which defenses could have changed the outcome.

Watch the course preview, then build the vocabulary, frameworks, and judgment needed to take credible first steps in ICS/OT cybersecurity.
