A project team is using Kanban. What is the primary mechanism for managing workflow?

Correct answer: Work-in-progress (WIP) limits

Option B is correct because in Kanban the primary flow-control mechanism is Work-in-Progress limits, which cap the number of items allowed in each workflow stage, preventing bottlenecks, exposing constraints, and creating a pull-based system that optimizes throughput. Option A is wrong because daily standups are a Scrum ceremony; Kanban has no prescribed cadence for standups and they are not its core control mechanism. Option C is incorrect because burndown charts are associated with Scrum sprints and measure work remaining over a fixed timebox, a concept that does not exist in pure Kanban. Option D is wrong because sprint planning sessions are a Scrum artifact tied to fixed-length iterations, which Kanban does not use.
