study case: Select the process you want to examine in the hospital $]$ laboratory. Define the scope $($be specific and include a

clear definition of the process, control materials, reagents, calibrators, system, or equipment to be studied$).$ Narrowing the

scope or focus is important because of human factors that could contribute to the process or

system vulnerabilities. Examples include communication errors, inadequate training, staffing

concerns, shift and shift change issues, and other barriers such as unclear rules, policies,

and$/$or procedures.
