Method of movement? Is that different from time and motion?
#1 - Routing to minimize drive time. Sometimes this means not taking a twenty mile drive even if you have an opening on the schedule. If you want to take that drive, book it far enough out so you can schedule other jobs in that direction on the same day. Exception: $2,000 job.
#2 - Buy some self-help books to build your self-esteem so you can skip "four to the door" or any other time-wasting goofiness that only you think makes a difference to your customer. Remember that the less time you feel have to spend building trust, the more the customer trusts you. Be professionally friendly, do the job and let them get on with their day. Exception: $2,000 job. Spend the day. Wash and put away the dishes while you're there.
Before you get to the house let the customer know how to be ready for cleaning. You may find that offering a discount if the customer moves small stuff will be your best investment.
As you drive up decided how to park and your layout to the house. As you walk up the first time, carry something and look for the water hook-up. Bring everything you need to the house (airmovers, rotaries) as this beats stopping your work to run out to the truck. Move furniture out, clean, move back, tab, clean the open areas.
