In my work life before home energy rating and home inspection, I was responsible for quality assurance (QA) in a food process facility. A key lesson we learn in QA is that we can only control what we can measure. If safe, enjoyable products with a long shelf life are to be produced, the manufacturer must have a detailed list of key process items (KPIs) that are closely monitored for deviation from acceptable quality limits. Homebuilding is remarkably similar to food production in this respect. The best builders use detailed procedures and best practices along with checklists to measure actual installation versus rigid quality standards. You can see the results in the improved finish detail and increasing number of amenities and features at affordable price points in new homes all over town. Visible and measurable home components improve at a rapid pace.
