Full Factorial Design

Full Factorial Design Full Factorial Design allows for experiments to include at least one test in all combinations of variables and levels. It is impossible to miss interactions with this exhaustive approach since all interactions between factors are taken into...

First Pass Yield (FPY)

First Pass Yield (FPY) This is the result of dividing the number of units that go into a particular process by a certain period of time. This is a key manufacturing metric for measuring quality and production performance. This relates to the efficiency of a particular...

np Chart – Monitor Number Defectives

An NP chart, also known as a number of defectives chart, monitors the actual count of defective items in samples of constant size. Unlike its cousin the P chart, which tracks the proportion of defects, the NP chart focuses on raw numbers, making it intuitive for...

One factor at a time (OFAT)

What is One factor at a time (OFAT)? One factor at a time (OFAT) is an effective problem-solving technique that identifies the most critical causes of an effect. Ceteris paribus, the approach is to change only one factor. All other factors (causes) are kept...

Overall Equipment Efficiency (OEE)

What is Overall Equipment Efficiency (OEE)? OEE (Overall Machine Effectiveness) is a gold standard in measuring manufacturing productivity. It is a simple way to determine the percentage of time spent manufacturing that is actually productive. A score of...
