High Voltage Test Data Gone Wild?

Nothing spurs data collection faster than a problem occurring in the Production line. As a company, we’ve gotten really good at gathering high voltage test data, product yields, process parameters, and all sorts of really good things.  The collection process continues to evolve in ease of use and sophistication. 

Having relevant data on hand helps to make informed decisions.  Without a doubt, it is a step in the right direction.  We analyze the data, make reports, create graphs, discuss it in meetings, formulate solutions, and implement plans until the problem either goes away or gets fixed.
Everyone knows how hard, if not impossible, to make good decisions without data.

The problem is, sometimes we forget to turn the data collection spigot off. As engineers, we move on quickly to the next project, and only look back when something catches our attention.

Finding the right balance between collecting data for its own sake (as in, “just-in-case something happens and we need traceability”), and discontinuing data collection because the issue has been resolved, is difficult to achieve.

Something else to consider – how important is data collection if no one looks at the data? Collecting, analyzing, and reporting all consume expensive resources. Sometimes these resources could be better spent somewhere else.

How do you determine when, if ever, to stop data collection?
