Identify and define control variables
Identify and define the variables that will be used to control the process and ensure its quality. These variables could include factors such as temperature, pressure, or humidity. Consider the impact of these variables on the overall process and the desired results. Determine the appropriate control limits for each variable and identify any potential challenges that may arise. Additionally, specify the required resources or tools needed to monitor and control these variables.
