Consider these points:

• Vehicle tracking via spreadsheet or whiteboard, while an improvement over sticky notes, is neither transportable nor shareable. In my experience, use of these tracking tools falls into disuse after a brief and energetic start.
• Misplaced vehicles can be taken out of the process temporarily while they await parts or repair authorization. The busy-ness of the day means these units are too easily forgotten about – or take time to locate again when ready to reenter the process.
• Misplaced communication between recon and the used-car manager slows repair approvals, causing delays that mount up and erode gross margin.
• Many compensation plans are based on time, not units of production

Each of these inefficient processes cost money – in time, labor and days in recon. 

The recon process should flow from point A to B in linear fashion. If that looks like an assembly line, it is. Your recon processes may not include each of the steps that this illustration shows, but running recon like a factory focuses on maximizing output and reducing cost.
