According to the Law of velocity, what relationship does process speed have with work in progress (WIP)?

The correct choice highlights that the speed of motion is inversely proportional to work in progress (WIP). This concept is key in Lean practices and emphasizes that as WIP increases, the overall speed of the process tends to decrease. When there is excessive WIP, it can create clutter and complexity within the process, leading to longer cycle times and potential bottlenecks.

This slowing down occurs because more items in progress can complicate workflow, making it harder to identify and resolve issues quickly. As a result, the focus shifts from accelerating the flow of the process to managing and coordinating a larger amount of work, which ultimately hampers efficiency. Lean principles advocate for limiting WIP to enhance speed and responsiveness in the process, thus aligning with the idea that effective flow depends on managing WIP levels effectively.

It’s important to recognize that while other choices may seem to suggest relationships between WIP and process speed, they either misrepresent the fundamental relationship or overlook the core principle established by Lean methodologies.
