Checklist items: worksheets (4) 7/12
Session Links
  • User-defined names use standard abbreviations
  • All numeric constants are held in named cells, and referred to by name, except possibly cells containing 0
  • All total cells sum the “correct” ranges
  • Array formulas are used where possible
  • There are no defined names that no longer exist (#REF!)
  • There are no circular reference errors

Here are some checklist items that encourage practices that reduce costs. Using standard abbreviations reduce the need of maintainers to refer to internal documentation. Checking that totals are correctly computed guards against a problem that arises when a row is inserted above a summing cell. Using array formulas reduces the chance that some cells fall out of sync with others. And of course, we want no circular references.

#REF! is one of Excel’s many error values, which are values cells can post when they cannot complete the evaluation of their formulas due to a calculation error. For more about Excel’s error values, see on-line help.

Inspect Your Project Early

Many believe that the main benefit of spreadsheet inspections is that they locate issues so they can be fixed. Certainly they do accomplish that. But spreadsheet inspections, when performed early enough and often enough, can actually prevent problems. And preventing problems is certainly more valuable than locating them.

We hope that you’ll apply what you learn about spreadsheet inspections when you work on your projects. If you’re working in a team, review your project schedule and decide when would be advantageous times to insert an inspection or two. If you’re working alone, ask someone else who’s working alone if they would be willing to inspect your project in exchange for your inspecting theirs.

Since we don’t grade on a curve, helping someone else doesn’t hurt you. Inspection exchanges raise the quality of both projects — and both grades. Whatever you do, don’t wait until the end to do your inspections.
