I have been given the task of upgrading/updating our current flat rate manual. The manual was done in house, and I'm not sure how they figured job time. I think they got together and decided among themselves how long a job should take. I need to know if there is a guide for job time. I thought there was a national average done as far as how long each task should take by an "average" tech. I am ok as far as the "hourly" rate and mark up on parts. Thanks for your help.
