 Before a process can be improved, it must first be standardized. This typically means detailing how the process flows (e.g., using flowcharts), along with standardized procedures, work instructions, infographics, etc. providing consistent instructions to workers within the process, and formalized training of workers (to ensure that personnel working in a process are competent to work independently). These are __all__ risk controls.  Before a process can be improved, it must first be standardized.

 +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.
 +
 +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 (2) 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).

 While most books on TRIZ focus on design, the key takeaway for modern Quality Professionals is, rather than focusing on "repairing" a process, to look at the problem and ask "What would be the ideal state?" This would often involve including Engineering personnel in the CI process.

-When radios first appeared, the signal had to be manually adjusted for optimal reception. +An example of TRIZ can be seen in the evolution of the radio. When radios first appeared, the signal had to be manually adjusted for optimal reception. 
  
 Then, during the mid-twentieth century, there was a technological breakthrough. Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), was introduced allowing the radio circuitry to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal. It was primarily used in radio receivers to keep the receiver tuned to the frequency of the desired station. Then, during the mid-twentieth century, there was a technological breakthrough.

-This takes us into a separate realm of "improvement" involving "innovation"... called TRIZ.+<WRAP center round tip 80%> 
 +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.
