Question

A Cumulative Flow Diagram (CFD) illustrates how lead time and Work-in-Process evolve over time. Which curve in the CFD primarily focuses on the items yet to be addressed?

a) Arrival curve ("to-do")
b) Departure curve ("done")
c) Combined curve ("in-progress")
d) Stagnation curve ("delayed")

Answer 1

The arrival curve in the Cumulative Flow Diagram represents the items that are yet to be addressed, capturing the accumulation of incoming or backlogged tasks over time.

Step-by-step explanation:

The curve in the Cumulative Flow Diagram (CFD) that primarily focuses on the items yet to be addressed is known as the arrival curve or the "to-do" curve. This curve visualizes how many tasks are incoming or how much work is being added to the backlog over time.

The departure curve, or the "done curve," shows the completed tasks. A combined curve shows the tasks that are currently in progress, and a stagnation curve could highlight any delays. Understanding these curves and their implications is fundamental to analyzing and managing workflow efficiently, ensuring that the CFD reflects the dynamism of the work environment and helps in predicting future performance.
