Your inputs are processed here and are not sent to VYRCO. There is no autosave: download your project before closing or switching languages. Opening JSON reads a local file; it does not upload it. CSV includes inputs and results. For PDF, use Print / PDF and select Save as PDF.

How to use it

Describe a specific observable problem.
Add one to five links; attach evidence to each explanation.
Define an action, an owner and how to check the result.

Fictional example

Fictional example about a hard-to-find file; names and records are invented.

Method

Original worksheet inspired by five-whys questioning. It preserves your statements and flags undocumented evidence or follow-up. The number of whys does not establish that a root cause has been reached.
