Our reports always have a section on things we looked at or for. Doing so takes a majority of the time it takes to write the report. Since it adds to the cost, firms that don’t do this can underbid the ones that do. For slimmed down reports that are published/given to third parties (given to the customer’s customer) it’s extremely important that the scope of the test is detailed in that letter. The charlatan firms will be happy to omit the fact that they only tested the “about us” page while blind-folded. So if you are reading a “letter of assessment” for something you are thinking of adopting, just look for the scope of the test, and if it sounds reasonable they potentially had a good test. If it’s missing, the test wasn’t worth the electrons in that letter.
