Checklists and audits may be one of the most basic approaches to quality but they frequently lead to problems of accurate data collection. A common issue that arises is not recording errors or defects in the field. Many trades that find an error when using checklists to review their work will correct a problem they find and not record it. They will say, yes BUT I found it, it was my fault and I corrected it, so it’s not an error! True, the checklist WORKED and the error was corrected, but by not noting it the data does not exist to show that for example this is a recurring theme on every jobsite. I have seen the same thing happen with audits, an inspector will find a problem and fix it and not record it, showing a great track record but ensuring that it will keep happening! This in turn means that a solution or fool proofing the procedure cannot be created and so the error will continue to be made. Accurate data collection, the solving of the root cause and prevention are fundamental for successful quality. Ensure that this is clearly understood and you will have a solid foundation to build on.
