9. The method of claim 1, which further includes additionally accumulating at least one of depth location data or sound data concerning the inspection to generate the workflow data.

10. The method of claim 1, which further includes updating the workflow rule using the workflow data.

11. The method of claim 1, further comprising:

or

preventing the inspector from continuing the inspection until the inspector satisfies the workflow rule.

12. The method of claim 1, which includes transmitting at least one of the workflow data or a report of the inadequate performance indication to an auditor.

13. The method of claim 1, which further includes displaying at least one of the workflow data or the video data of the inspector performing the inspection procedure to an auditor.

14. The method of claim 1, which further includes:

counting a number of inadequate performance violations associated with the operator; and

transmitting a message to an auditor if the number of violations exceeds a predetermined threshold.

15. The method of claim 14, which includes forming the predetermined threshold based on a type of the inspection procedure.

16. A system for monitoring an inspection workflow comprising:

inspection software configured to

(i) identify an inspector in an inspection area inspecting a vehicle,

(ii) determine an inspection procedure that is being performed by the inspector, the inspection procedure being at least a portion of a vehicle inspection, and

(iii) generate workflow data by monitoring the inspector within the inspection area using data received from at least one of a camera or a depth sensor;

rule software configured to determine a workflow rule that corresponds to the inspection procedure, the workflow rule including at least one workflow limit; and

compliance software configured to determine whether the inspector violated the workflow rule by comparing the workflow data to the at least one workflow limit of the workflow rule.

17. The system of claim 16, which further includes management software configured to generate an indication if the inspector did not adequately perform the inspection procedure.

18. The system of claim 16, wherein the compliance software is configured to determine if the inspector satisfied the workflow rule by determining if a tool authorized by at least one of the workflow limits of the workflow rule is used by the inspector.

19. The system of claim 18, wherein the tool includes an identifier that is detectable by the camera to enable the identifier to be referenced to the workflow rule, the identifier including at least one of a colored indicator or a shape.

20. The system of claim 19, wherein the shape includes a directional indicator that is used by the compliance software to determine if an action specified in the workflow rule has been adequately performed.

21. The system of claim 18, wherein

the inspection software is configured to detect an identifier on the tool and the compliance software is configured to

(i) compare the workflow data including movement of the tool to the at least one workflow limit of the workflow rule, and

(ii) determine the inspector violated the workflow rule when the movement of the tool does not match a predefined tool movement specified by the workflow limit.

22. The system of claim 16, which includes a database to store data generated by at least one of the camera or the depth sensor when the inspector violates the workflow rule.

23. The system of claim 16, wherein the inspection software further operates with a microphone positioned and arranged to detect sound from the inspection area.
