Quality In, Quality Out

What Does Quality In, Quality Out Mean?

Quality in, quality out (QIQO) is a phrase that refers to the fact that the value of the inputs usually influences the value of the output. Quality in, quality out is a more optimistic take on the concept of garbage in, garbage out (GIGO). In practice, it means that as long as the data going into an application or analytical model is good, the resulting work done by the application or model will be accurate.

Techopedia Explains Quality In, Quality Out

Many important applications rely heavily on the quality and accuracy of the data being fed into them to produce accurate outputs. These include risk modeling software, cost projection software, resource management software, and so on. If an application is inherently flawed, it is the developer's fault. However, even if an application is working properly and the customer’s data is flawed, the developer still gets the blame. QIQO and GIGO both express the frustrations of application developers with the end users of their work. QIQO is the more polite, customer-friendly way of explaining why an output isn’t accurate.
