A checkpoint intentionally impedes progress to allow for adequate inspection. If progress is not impeded enough, the inspection is inadequate; if progress is impeded too much, those being inspected become angry.

For each of the following types of inspection:

1. Make sure no one / nothing bad gets onto a commercial flight

2. Make sure only authorized users gain access to an application

3. Make sure the software development organization is improving

4. Make sure a prototype application is acceptable to the users

5. Make sure an application meets requirements

6. Make sure infected persons are prevented from entering a lecture hall

Examine and report on each of the following issues:

a. How will flow be impeded to support adequate inspection?

b. What automated tools can be used to facilitate achieving adequate inspection while maximizing flow?

c. What metrics can be collected/analyzed for ensuring that progress is impeded by just the right amount?, and how can they be collected/analyzed automatically?

d. What are the drivers of cost?

e. How can the inspectors prove that the checkpoint is worth it (i.e., benefit > cost)?
