.Rolled Throughput Yield (RTY) and First Time Yield (FTY) are both important metrics used in the context of process improvement and quality management. While they are related, they represent different aspects of quality performance.

First Time Yield (FTY):

First Time Yield (FTY) is a measure of the effectiveness of a process in producing defect-free output on the first attempt. It calculates the proportion of units or products that pass all quality checks and meet the required specifications without any rework, repair, or rejection. FTY is typically expressed as a percentage, ranging from 0% (no units pass) to 100% (all units pass).

For example, if a manufacturing process produces 900 units and 800 units pass all quality checks without any need for rework or repair, the FTY would be 800/900 or approximately 88.9%.

Rolled Throughput Yield (RTY):

Rolled Throughput Yield (RTY) is a measure of the overall effectiveness and efficiency of a process in producing defect-free output, considering all process steps or stages. It takes into account the yield at each stage of the process and calculates the cumulative yield or the probability of producing a defect-free unit from the beginning to the end of the process.

RTY is calculated by multiplying the individual yields of each process step. For example, if a process consists of three stages, and the yields at each stage are 90%, 95%, and 85%, the RTY would be calculated as 0.90 * 0.95 * 0.85 = 0.7275 or 72.75%.

RTY considers the cumulative impact of each process step on the overall quality performance, including the potential for defects introduced at any stage to propagate through subsequent stages.

In summary, FTY focuses on the proportion of units that pass all quality checks on the first attempt, while RTY provides an evaluation of the overall effectiveness and efficiency of a process by considering the cumulative impact of each stage's yield on the production of defect-free output.

Please check your description on your post. FTY and FPY are two difference indexes. FTY is the the yield of good part leaving the process line with and without the need of rework/repair. FPY is the yield of good part leaving the process line without the need of rework. But what your mentioned in your video is correct...:)

Rolled Throughput Yield (RTY) & First Time Yield (FTY) (2024)

FAQs

How do you calculate RTY and FTY? ›

First Pass Yield (FPY) and Rolled Throughput Yield (RTY)
  1. FTY = (entering units - scrapped units) / total entering units.
  2. FPY = (entering units – scrapped - reworked units) / entering units.
  3. RTY = (entering units – number of all defects) / entering units.

What is first time yield and rolled throughput yield? ›

The key difference between Rolled Throughput Yield and First Time Yield is that RTY considers the total number of defects in a multi-step process, while FTY only focuses on the defects in the first step.

How is first time yield (fty) calculated? ›

FTY is unit sensitive, meaning it does not take into account whether the output unit is defective, and is calculated by dividing the number of units produced from a process by its inputs. It does not capture how many defects were found and corrected within a single unit.

What is the difference between throughput yield (ty) and rolled throughput yield (rty)? ›

You can multiply the individual throughput yields at each process step to obtain the overall, rolled throughput yield. When you calculate throughput yield, you count only the units that make it through the process without rework or scrap.

How is first pass yield FPY calculated? ›

First pass yield = (number of good units produced / total number of units produced) x 100First pass yield refers to the turnout of a production cycle or the number of goods a company can actually sell to customers after the production process.

What is an example of a first time yield? ›

First Time Yield (FTY):

FTY is typically expressed as a percentage, ranging from 0% (no units pass) to 100% (all units pass). For example, if a manufacturing process produces 900 units and 800 units pass all quality checks without any need for rework or repair, the FTY would be 800/900 or approximately 88.9%.

What is a good rolled throughput yield? ›

Rolled throughput yield is the probability of a product or service making it through the entire process without having a single defect. Ideally, you want this value to be 100%, but that can only happen if all products pass each process step 100% of the time.

How to calculate film yield? ›

To calculate the yield of a square inch of film, multiply the thickness (gauge) by the density, then divide by 27.68.

How do you calculate yield? ›

For stocks, yield is calculated as a security's price increase plus dividends, divided by the purchase price.

What is the FTY score? ›

First Time Yield (FTY): The ratio of the number of good “units” coming out of the process to the number of “units” going in. Rolled Throughput Yield (RTY): The probability that the process produces a good “unit” the first time through.

How to calculate right first time? ›

First time right defined

It boils down to this formula: FTR = (number of usable products divided by the total number of products) x 100.

What is the difference between throughput and throughput time? ›

The term throughput time comes from the measure of throughput - or the business process flow rate. Throughput is the measure of inputs and outputs within a process and is an important aspect of business process management.

What does the throughput ratio tell us? ›

Throughput rate calculations can help a business determine the rate at which deliverables reach consumers. Sometimes referred to as flow rate, this information can help a business make knowledgeable decisions about the production process from investment to production to revenue.

What's the definition of rolled throughput yield quizlet? ›

Rolled Throughput Yield (RTY) is the probability that a single unit can pass through a series of process steps free of defects. If you will remember, the First Time Yield calculation we did (FTY) considered only what went into a process step and what went out. Rolled Throughput Yield adds the consideration of rework.

How to calculate final yield? ›

It is obtained by counting the defect-free units that successfully complete the entire process divided by the total units entered the process. In other words, if the number of units at the end of the process equals to what they were at the beginning, then the final yield would be 100 percent.

How to calculate RTY from DPU? ›

RTY: Using an Estimate of Yield

It is also possible to “estimate” Yield by taking the inverse of DPU or simply subtracting DPU from 1. Referring to the table above, let's run a quick yield estimation. RTY using the Yield Estimation Method = 0.89*0.91*0.99*0.98*0.97 = 0.76 or 76% very close!

What is the formula for total yield? ›

You can follow these steps to calculate yield: Determine the market value or initial investment of the stock or bond. Determine the income generated from the investment. Divide the market value by the income.

What is the formula for yield factor? ›

The formula is EP weight ÷ AP weight × 100 = yield %. Yield percentage is important because it tells you several things: how much usable product you will have after processing; how much raw product to actually order; and the actual cost of the product per dollar spent.
