Maybe it’s because I’ve been swamped this week while the sun’s been shining here in the beautiful Pacific Northwest, but I’ve been doing some thinking about buffer, downtime, and productivity. I don’t think it’s a secret that projects have a tendency to come in late sometimes. Things come up, bad stuff happens, tasks are delayed…not uncommon. So how do you deal with it? You schedule in some buffer time to help offset the impact of changes to your project schedule. This isn’t rocket science, but is it the right approach?
First let’s talk about productivity. I was reading through Twitter the other day, and David Allen, who you may know as the “Getting Things Done” guy (@gtdguy), had replied to someone else about letting go/relaxing as a prerequisite for productive intensity. This got my attention. A lot of times we don’t think about buffer in terms of enhancing productivity and encouraging teams to get things done on time. Instead, we focus on buffer as one part of a realistic approach to scheduling. Well of course we do, because that’s what it is. But I think it’s important to also remember that A) there are actual *people* working on your projects, B) people tend to be more productive when they feel relaxed, and C) if a project has buffer scheduled in, the people working on that project are bound to feel less stressed than if the project had no buffer. That’s all I’m saying…you do the math.
So there’s the productivity aspect, but what else? Well after I replied to @gtdguy’s tweet, another fellow Twitter-er replied to me, suggesting that maybe some PMs aren’t doing proper risk response planning. Instead, they’re including buffers, with risk as the justification. Interesting idea. On the one hand, hey, at least they’re including buffer, but on the other hand, it’s important to remember that risk management isn’t just some kind of lightweight throwaway work. I mean, PMI’s got an entire certification for Risk Management Professionals. This is serious business. It also could be the reverse…that some organizations have full-on risk management happening, but it’s happening outside of the project schedule, so buffer in the plan itself is being overlooked. And then we’re back to that productivity discussion again. It seems to me that the right answer is a combination of both. Risk management *includes* scheduling buffer. With both in place, you’ve really got a handle on those what-if scenarios, and your team feels supported because you’ve recognized the reality of schedules slipping for one reason or another.
I’m wondering what the reality is out there. Do you include buffer in your project plans? Where, as separate line items, or as padded work estimates? If you don’t include buffer, why not? How do you implement risk management in your project schedules?
