- Are clients complaining/leaving as a result of efficiency points?
- Does the workforce use any efficiency testing instruments at present?
- How is DevOps concerned with efficiency testing? (At some firms, QA does not do efficiency testing, however DevOps will!)
- Do you count on efficiency testing to be completed in manufacturing or in non-production environments? (This lets you decide the extent of danger they’re prepared to just accept!)
- Are you prepared to pay for instruments to assist with efficiency testing?
- Are there any monitoring instruments setup to log or alert on efficiency points in manufacturing?
Hopefully, this helps for subsequent time you encounter this query. And, factors you in a path to be taught new expertise!
