Term Definition
Financial Benefits Categories

A matrix of four quadrants that categorize the types of benefits typically yielded from projects. The categories are determined by two factors: 1) Impact to Cash (direct or indirect), and 2) Impact to the Business (tangible or intangible). The four categories are 1) Direct/Tangible Impact (e.g., increasing revenue, decreasing costs, etc.); 2) Indirect/Tangible Impact (e.g., shift headcount, accelerate cash flow, etc.); 3) Direct/Intangible Impact (e.g., avoid lost revenue, avoid additional costs, etc.); and 4) Indirect/Intangible Impact (e.g., improve customer satisfaction, compliance issues, etc.).

First Time Yield (FTY)

A measure of the % of non-defective units successfully output the first time through a process. Subtracting the result from 1.0 (or 100%) will yield the potential waste (defects) in the process that can be eliminated. It is ideally a measurement of the capability at the sub-process level contributing to Rolled Throughput Yield (RTY).
