You can learn a lot about productivity from a home renovator. We had some work done in our basement recently. It’s the kind of work that anyone might do. We wanted to fix up an unfinished room, the size of a bedroom. We needed it because we rented out our house for the summer. We would be travelling to Europe, visiting museums, exploring cathedrals and remotely conducting our time and motion study projects. In the basement a small brick wall needed to be taken down – because of some previous renovations, it was redundant. And the ceiling needed new drywall to make it into a serviceable guest bedroom.
A while back, we met the contractors, agreed to a quote, and set a date for them to begin. It was a month out because they had another job to finish. That was fine with us. It seemed like good scheduling when they had a window to do our relatively small job. Maybe a week beginning to end.
But the job ended up stretching out over three weeks. On this basic productivity measurement, the contractor failed. His company had another job, and needed to give it priority. So someone showed up at our house for two or three hours to do some work, and then poof! They were gone.
The contractor thought he was being efficient by booking two jobs at once. Do a bit of work here, wait for something to be ready, then off to the other place to nail some studs, and then back to the first place again for the next bit. Two clients at once! Busy, busy.
Waste, waste is more like it. There is a huge productivity inefficiency to starting and stopping a project. First is travel time. If a job extends out for ten days instead of five, then that’s ten extra trips (there and back) for each extra day. Most trips are at least a half hour, so there’s an extra five hours of time right there. Also, most contractors clean up at the end of each day. So that means more clean up time. And more set-up time at the beginning of the next day. All those tools that were put away have to be brought out again.
And then there is reset time. All of us need time to get refocused after an interruption. Contractors are no different.
We know another contractor who is much more productive. He shows up early in the morning and works right through until the end of the day, rarely taking a break. If something has to wait – concrete drying for instance – he schedules that towards the end of the day. If it has to be in the middle of the day, he always finds something else to do. He plans out his work using basic project management techniques. As a result he finishes on time with little waste.
So the next time a contractor quotes you – ask how many other jobs he is doing, and what he does to minimize waste. Ideally, ask for a completion date, and build in a penalty clause for every day he goes over what didn’t result from a change you requested.
Your time is worth it.
