I have carried out a supplier audit, on assessing their very compreshensive test protocols which were in Excel spreadsheets that did not have any security (e.g. locked cells) and the individual test steps were not individually signed-off. There was a tab in the workbook for the information of the tester.
Whilst I don't believe anything was falsified or not correct, I am used to seeing tests that are approved either by row, or by section and not 100s of lines grouped together.
Is this something that I should raise as a concern, or is it acceptable for a forward thinking software company to use uncontrolled, non-validated spreadsheets as part of official system testing?
