Error-Proofing Made Simple

leave a comment »

Error-proofing is preventing errors rather than just warning about them.

With compiler warnings, that means setting warnings-asCannot throw away fast-food tray by mistake says Mark Graban-errors in your compiler so you cannot complete your build. Yes, you also need tests that can fail and a source control system that refuses promotion of versions that fail test. And code review to ensure that code changes to address compiler warnings only improve the code. But the key is warnings-as-errors.

While error-proofing is simpler with fast-food trays, the idea is the same. Read “Simple, Brilliant, Error Proofing at the Amazing In-N-Out Burger” (Mark Graban  |  04/11/2011  Quality Digest) and look for where else you can error-proof your process.
