I worked at a company where the owner started a program where everyone in the company started learning and understanding how the business profited and actually made or loss money.We would also learn about how we cost more to the company than just our rate of pay.We also had started a bonus program per job, so that everyone got paid a certain of the bonus of the job(whoever worked on it)as long as the job made money.This bonus wasn't paid out until the entire job was fully paid by the customer, which was only after all the problems or bugs were worked out.This keeps the quality level high and the time on the job more productive.To keep installers happy you need to feed our egos and tell us how great of a job we did and we will always be happy!!!
