| EVERY Inspection point is a "risk control". Inspections are performed because the process is not reliably producing consistent conforming products. Quite often, once an Inspection point is established in a Work Router/Traveler, it remains despite improvements in the process. Performing a Pareto analysis of the types of defects that an Inspection point is detecting will indicate which portion of the process is producing nonconformities. THAT should be the focus of a CI project. | EVERY Inspection point is a "risk control". Inspections are performed because the process is not reliably producing consistent conforming products.

| If the CI project eliminates the non-conformities, then the Inspection point can be eliminated. However, if there are "Technical Contradictions" (discussed later), then (1) Inspections should be limited to only those characteristics regularly found to be non-conforming, and (3) the Inspection point may need to be moved closer to where the nonconformities are being produced (at an optimal point in the production process flow). | If the CI project eliminates the non-conformities, then the Inspection point can be eliminated.

| There are constant advances in virtually every sector. Consequently, a review of advances in technology should be included as a part of the CI process. | There are constant advances in virtually every sector.

| | Prior to initiating a CI Project, ALWAYS check with Engineering to ensure that the current product(s) isn't about to undergo a major change/revision that would impact the production process. Similarly, ensure that existing product(s) isn't scheduled to be discontinued. |
