What is meant by first pass yield?

A measure of quality in a process that reflects the percentage of product made correctly without any rework or corrective activity.

What is first pass yield in lean?

Lean Definition This is a measure of the yield that results from the first time through the process, prior to any rework. It should reflect all defective units detected since the preceding yield test point.

What does our first pass yield KPI measure?

First pass yield is a key performance indicator (KPI) that measures the successful manufacturing of a given product. It’s a great KPI for understanding how successfully a given manufacturing process is at creating functional products.

What is the importance of first pass yield to customer?

First pass yield is a good measure of the effectiveness of a process and the elimination of waste from that process. Many other measures of productivity and efficiency fail to account for the cost of rework and in many facilities rework can be a significant portion of the time and value added to final production.

What is first pass yield and why is it important?

First Pass Yield is an important manufacturing metric for measuring quality and production performance and there are many benefits to including first pass yield in the manufacturing executive’s dashboard. First pass yield is a good measure of the effectiveness of a process and the elimination of waste from that process.

What is the first pass yield of process D?

75 units go into process D, 8 are reworked, and 70 leave as good parts. The FPY for process D is (70-8)/75 = 62/75 = 0.8267 First pass yield is only used for an individual sub-process.

What is first pass yield in KPI?

KPI Details. First Pass Yield (FPY) is an indicator that gauges the production and quality performance of a Manufacturing group, based on the number of good vs. defective units produced. FPY can be a good measure of a company’s progress in continuous improvement efforts, since continuous improvement is often concentrated on the reduction of

What is the difference between first pass yield and rolling throughput?

First pass yield is only used for an individual sub-process. Multiplying the set of processes would give you Rolling throughput yield (RTY). Notice that the number of units going into each next process does not change from the original example, as that number of good units did, indeed, enter the next process.
