Doing weekly checks to make sure processes are followed is a countermeasure to a problem. Lean orgs start with the problem. They take the time to assemble the people closest to the work to understand the root cause and to test the countermeasures before calling them solutions. I’ve made some inferences based on your question about not following procedures, and built an example to illustrate:
PROBLEM STATEMENT: From January through March, there were 20 instances of unsuccessful service tickets requiring a second service ticket (re-do), resulting in 60 non-billable hours, 10 unhappy customers, and the potential for loss of confidence in our company. (Note: a quantified problem with the negative impact to the organization)
CHAIN OF CAUSALITY: Why were there 20 instances of unsuccessful service tickets?
Because the techs worked on the wrong things.
Why did the techs work on the wrong things?
Because the techs made incorrect assumptions about the problem.
Why did the techs make incorrect assumptions about the problem?
Because the service ticket did not contain the problem specifics.
Why didn't the service tickets contain the problem specifics?
Because the service tickets were not fully completed.
Why weren't the service tickets fully completed?
ROOT CAUSE: Because we have no system for reinforcing service ticket completion.
HYPOTHESIS: IF the service ticket is fully completed, THEN the right problem will be solved the first time and a re-do will not be needed.
EXPERIMENT: From May through July, we will fully complete service tickets. We will track the number of re-dos needed and assign a reason for the re-do. From Jan-Mar, 20 re-dos were needed due to incomplete information. From May-July we expect less than 3 re-dos due to incorrect information.
COUNTERMEASURES to support the experiment.
