In DEPTH Cause Analysis for Equipment Problems
Equipment degrades, malfunctions, or fails outright... hopefully not too frequently, but every breakdown can be painful. So, of course, you will want to figure out exactly what happened, how it happened, and why (in hardware/software terms). You may want to dig a little deeper, though; every equipment malfunction or failure that you have is a valuable datapoint for gauging the health of your overall equipment program. That's why I've started creating a tool that should be able to help find programmatic causes underneath the more easily observable equipment performance issues. Since it is intended to be a Diagnostic for Equipment Programs, and uses Tabulated Heuristics, I call it DEPTH.
An early alpha release of the DEPTH tool is linked below, and you are free to download it and review it, try it out, share it, etc. However, I've got a couple of important notes and requests I'd like you to read before downloading the tool.
- This is an early alpha release, and it is incomplete. For instance, definitions or explanations for the "codes" are not provided. (You'll know exactly what I mean when you open the file.) Your use of this tool is at your own risk.(And mind the disclaimer!)
- While I'm giving this away, I'm not releasing it to the public domain, or even distributing it as open source yet. Treat it like an article published in an industry journal; you wouldn't just go and claim something like that as your own, but you could share it, use it, reference it, etc.
- Please Please PLEASE give me feedback. The URL for this article is provided on the tool itself... please leave comments here and tell me what you think about the tool, what you would like to see changed, etc. I'll keep trying to improve the tool on my own, but your feedback is extremely valuable.
Alright... here it is. Download, review, use, and then COMMENT. (Note: I found a stupid error on the first version I posted; the error has been fixed and a new version uploaded.)
Finally, remember the wise words of George E. P. Box: "All models are wrong, but some are useful."
