What's Your Distraction Factor?
I am thrilled to announce that I have a new acronym to add to the Project Management lexicon. Let’s squeeze some more space into PMBOK to make room for:
“DF” - the Distraction Factor!
(You can contact me through the blog if you’re interested in ordering t-shirts…)
In a recent blog post, Jennifer Russell discusses the idea of work effort vs. work duration. These two things can be very different. Work effort is the number of hours it would take to complete a task and work duration is the number of work days that will pass until the task is complete. So, if a team member tells you that his task will take 8-16 hours to complete, that's the effort. If he is able to spend only half his day on your task, then its duration is 2 - 4 workdays.
This is always a big disconnect between upper management and the project team.
"The task is 8 hours? So he'll finish it today!"
The first problem here is that upper management will ignore the fact that you provided your estimate in a range, and then they will assume your team member is both 100% allocated and 100% efficient. Factoring in resource allocation is easy to do when using effort to come up with duration. You've only got that guy on your project 50% of the day? Ok, assume the 8-16 hr task is now stretched to 2 - 4 days. But that’s only the beginning.
What about productive working hours? This is where things get interesting. Let's assume the team member is required to be at his desk and 'working' for 8 hours. We're all human--is it realistic that he’ll get 8 productive hours of work done? As project managers, our job is to minimize distractions, but some are inevitable.
Maybe what we need is a term to describe this “leak” of productive working time – this is where my new term ‘The Distraction Factor’ comes in. I propose the following strategy to come up with the distraction factor for each of your team members:
1. Spend the day watching him work. Make up some bogus reason why you need to, and I’m sure he won’t mind. I mean, who doesn’t enjoy having someone look over his shoulder all day, right??
2. Log the time he spends working on his task, and the time spent doing ‘alternate activities’, i.e. time being distracted.
3. Be sure to label each distraction. You will probably notice a pattern among your team members: some like to shop online, some are Facebook addicts, some instant-message with their friends all through the day, some tweet. You can come up with code names for your team members, like ‘The Facebooker,”or “The Shopper.”
4. What about distractions away from his desk? Once he gets up, follow a few steps behind him and go see what he’s doing!
a. Smoke break?
b. Phone call to his wife?
c. Long argument over the phone with his contractor?
d. Extended visit to the bathroom?
All of these distractions must be noted.
5. Then there are those coworker distractions…chatting with a coworker, gossiping about his boss, helping someone recover a crashed document, lending a hand while the office manager cleans all of the science experiments out of the office fridge.
We don’t really care here about what’s ‘ok’ and what’s not, we are accepting the reality of your team member’s habits and tracking them as closely as possible. One idea is to spend a week monitoring each of your team members, so that you can get a low/high range estimate of each of their distractions. We like ranges here, as you know. Once the monitoring is complete, (assuming you still have a job and your team members haven’t all quit on you or firebombed your house) you should be able to come up with a formula that looks something like this:
True Availability = (Hours per day resource allotted to you) – (Distraction Factor)
Where Distraction Factor = (FB + AIM + SMOKE + SHMOOZE + UNNECCESARY MEETINGS) [in Hours Per Day]
This is just one example of the Distraction Factor formula, but of course you’ll be able to come up with a unique formula for each of your team members. Now, with LiquidPlanner you can apply this new knowledge to the “Availability” area and enter in the number of hours that the team member is really available to work. This will allow the LiquidPlanner schedule to be even more accurate than it was before!
Be sure to repeat this process every few months or so. As personal life and other situations change for your team members, distraction factors will of course fluctuate.
Happy calculating!
*Obviously, this is a bit of a joke. But accounting for overhead in order to understand the true number of hours people have to spend on project work per day is no joke. It’s a critical part of building an accurate schedule. Just a friendly reminder.

Love the DF idea!
It reminds me of a small organization I know in the Chicago area. The top exec was concerned that people weren't using their time well. All his directs were asked to keep a time log of their activities for a week. One of his directs submitted a log that included "Waste time on Internet: 90 minutes".
Points for transparency, I suppose, but he might have looked wiser if he could have thrown in a little DF obfuscation! :)
Dear Dina,
I like your article. I am quite happy to take the DF on board and to refer to it. However, instead of taking it as a value to subtract I would prefer to use a ratio (%). This is because the 'D' can occur at any time during a task - any hour, any day, or any week.
Example: a task nominally requires an effort of 14 hours of work (i.e. 14 wh - work.hour). I'll assign it to one person who has a DF at 25%. Therefore I should plan for 14 wh /.75 that is 19 wh (from 18.67 wh by benevolence).
Also, bearing in mind that your observations are very pertinent, we have to accept that there is always an uncertainty about the 'D'. Depending about the individual, we need to dream the task before think about it, we need to think the task (planing) in our head before acting, then we act. Then we need to peer-review or test. Then we need talk to about it around before delivering. Some of these activities may be done while chatting at the coffee-machine and only the 'act' part maybe visibly considered as 'work'. But of course, you were emphasizing the external events in your example.
Also, there is often confusion between 'duration' and 'effort'. Value is in the non-wasted 'effort' and not in the 'duration'.
