Increasing the amount of time someone spends on work does not directly result in better work. In fact, depending on the person, the opposite may be the case—spending less time at the office may improve the results. Johanna tackles myths of measuring work by time.
"Have you heard the new thing that Andrew is doing?" Gabe asked, shaking his head as he headed towards the cafeteria with Cynthia.
"No, what?" Cynthia said.
"We have to fill out time cards with our actual time on them. He wants to know how much time we really spend at work. The more time, the better."
Cynthia stopped. "Are you serious? I thought I'd seen everything, but this really takes the cake."
"Yeah. We're supposed to be about 'sustainable pace.' This crazy time card thing is going to make the pace anything but sustainable. I don't understand why he thinks he can measure our output by the time we spend here. I have good days and bad days. Sometimes, I think I spend a lot less time here on the good days and produce twice as much! Of course, sometimes, I just stop writing code on the bad days so I don't produce four times as many bugs!"
Cynthia grinned. "Well, I’ve certainly had those days. How can we make Andrew see the error of his ways? Maybe get Tina, the other director, to talk to him?"
"Maybe. Or maybe we should explain that velocity has not much to do with time spent at work. Maybe we should baseline our features per week now and measure our features per week after he does this time card thing, especially if he insists on overtime. What we have to do is make our pain his, because this is total craziness."
Time Is Not Results
I've seen managers try to reward employees by the number of hours that the employees' cars were in the parking lot. People can game that measurement easily—just leave the car in the parking lot for the week. A colleague did that and was only discovered after the snowplow plowed around his car after a surprise snowstorm. He had already gone home for the storm and had left the car. His management was quite surprised and quite angry about the employee's deception.
When you use time as a measurement for how good people’s work is, you beg them to game the system and exhibit some of this crazy behavior. Time at work does not equate to good work. It never has, and it never will. Oh, you can't work without spending time working somewhere and on the work itself, but that doesn't mean that you have to spend lots of extra time at work.
How Much Time Can People Work in a Day?
Everyone's day will be different, but there is some upper reasonable limit to how much people can work in a day. People can work about eight good hours a day on an intellectually challenging job before mental exhaustion sets in. Some people can work fewer than eight hours. This means that if you want people to accomplish more work, then you should restrict their time at work to no more than eight hours a day.
Some of you are saying, "Huh? What did Johanna just say? Restrict the time at work?"
Rank the Work
When you timebox the time people spend at work, they will start to make decisions about the work to do. They will postpone the not-important-enough work. They will start to prioritize the remaining work. That means they will start to manage their individual project portfolios. They will start to rank the project work.
They will decide to complete the strategically important work. Or, if they are not sure, they will ask you. Expect some tough questions about which projects are most important. That’s OK, because if you are a manager, you need to be able to answer those difficult questions. And, if you have decided that people are not machines and you cannot expect 100 percent utilization because that’s craziness, then you already have started to rank the project portfolio.
