Visualizing the workflow
Kanban is a method to manage work by visualizing it on a board with columns (for example: To do → In progress → In testing → Done). Its goal is to improve flow and reduce half-finished work.
WIP limits
Kanban's central concept is the Work In Progress (WIP) limit: a maximum number of tasks in each column at once. Limiting WIP prevents overload, reveals bottlenecks and speeds up delivery.
If the 'In testing' column piles up and exceeds its WIP limit, it signals a QA bottleneck: the team should help clear it before starting new work.
