Kanban is based on which concept?

• A. Predictive model
• B. Pull system of work assignment
• C. Incremental delivery approach
• D. Dynamic System Development Method

Answer: (B)

Kanban is built around a pull-based flow of work. In Kanban, work items are pulled into the next stage only when capacity is available, and WIP (work in progress) limits keep the flow smooth and visible on the board. This visualizes how work moves through the system and helps teams manage throughput and spot bottlenecks, rather than trying to forecast and fix all scope upfront. While incremental delivery can occur with Kanban, the defining idea is the pull system that drives continuous delivery and adaptive planning. The Dynamic Systems Development Method is a separate structured agile framework with its own lifecycle and timeboxing, not the core principle of Kanban.
