The V.A.I.Y.L. Framework

A structured way to examine variations in operator experience.

The V.A.I.Y.L. Framework is a lightweight method for examining variations noticed by operators during normal work in complex operational systems.

It provides a simple structure for capturing operational observations, examining them through the V.A.I.Y.L. sequence, and developing insights about system behavior.
