RTE Value Stream Management 2

Question 1

What is 'Lead Time' in Value Stream Management?

Accepted Answer

The total time from when a customer request is made to when value is delivered to the customer

Answer

Lead Time is the end-to-end time from when a customer need is identified to when value is delivered, and reducing it is a primary goal of Value Stream optimization.

Question 2

What is 'cycle time' and how does it differ from lead time?

Accepted Answer

Cycle time measures active work time on a specific item, while lead time measures total elapsed time including waiting

Answer

Cycle time measures only the active working time on an item, while lead time measures the total elapsed time from request to delivery including all wait states.

Question 3

What is the 'cost of delay' concept and why does the RTE need to understand it?

Accepted Answer

The economic impact of delaying the delivery of a valuable feature, used to prioritize work in the ART and portfolio backlogs

Answer

Cost of Delay quantifies the economic impact of not delivering a feature on time, helping Product Management and the RTE prioritize work based on value and urgency.

Question 4

How does the RTE use Value Stream thinking to improve ART performance?

Accepted Answer

By identifying bottlenecks, reducing WIP, eliminating handoff delays, and improving the flow of work from idea to delivery

Answer

The RTE applies Value Stream thinking by visualizing the entire delivery flow, identifying bottlenecks and waste, and facilitating improvements that increase throughput and reduce lead time.

Question 5

What is a 'bottleneck' in a Value Stream, and how should the RTE handle it?

Accepted Answer

A constraint that limits the throughput of the entire value stream, which the RTE addresses by focusing improvement efforts on that constraint first

Answer

A bottleneck is the step in the value stream that constrains overall throughput, and the RTE should focus improvement efforts there, as it limits the entire system's output.
