It has always been a balance between lecturing and doing research. And doing research has always been regarded as the most important part to enhance your status. The only way a lecturer who focuses on lecturing could catch up would be to deliver a lot of post-graduate students. As far as research is concerned, obviously your first priority was to get your PhD. Then do research for the rest of your academic life. And if your articles are not published in accredited international publications, they really don't mean much. Maybe one should simply apply the model of productivity suggested above and see what happens. It will soon become clear where the model should be adapted.

I've started gathering some data and hope to post something in a week or two (I'm going to a conference next week which will mess up the data slightly). Quick question: have you used any special techniques to assign the 1-10 scores for usefulness and difficulty or are they best guesses? Wow – that’s great Benjamin.

I am a Master's student and am just starting to write my thesis, so my work consists of reading, writing, research, procrastination, etc. Day 1 Task | Usefulness | Difficulty | Time | Productivity Planning | 4 | 3 | 15 | 2.4 Trying prod. formulas | 2 | 4 | 120 | 0.7 Solved math question | 1 | 8 | 135 | 0.3 More on prod. formulas | 2 | 4 | 60 | 0.8 Installed soft. imported i | 5 | 4 | 90 | 2.0 TOTAL productivity = 6.3 avg. hourly productivity = 1.3 Day 2 Task | Usefulness | Difficulty | Time | Productivity Planning | 4 | 2 | 15 | 2.7 Fixed comments, form. | 7 | 4 | 90 | 2.7 PDF settings LaTex | 4 | 3 | 45 | 1.9 Wasted time online | 2 | 1 | 45 | 1.2 Wasted more time | 1 | 2 | 30 | 0.6 Continued formulas | 7 | 4 | 150 | 2.5 Unaccounted time | 0 | 1 | 45 | 0 TOTAL productivity = 11.6 avg. hourly productivity = 1.7 Day 3 Task | Usefulness | Difficulty | Time | Productivity Email for meeting | 7 | 4 | 30 | 3.4 Wasted time online | 1 | 1 | 30 | 0.7 Planning | 5 | 3 | 45 | 3.0 Fixed intro, objectives | 9 | 6 | 90 | 3.3 Found and read manual | 5 | 3 | 60 | 2.2 Played with some data | 5 | 4 | 60 | 2.1 Unaccounted time | 0 | 1 | 135 | 0 TOTAL productivity = 14.6 avg. hourly productivity = 2.1 When I look at these results, I agree with the way the formula ranks tasks and total productivity... You can also add a a task with 0 usefulness and difficulty of 1 that accounts for the rest of a workday (wasted time that is not accounted for in these tasks); this then allows you to compute your average hourly productivity for the day. The choice of the log function is based on a few considerations. Without it, the value of productivity is a very small number, difficult to understand and compare. Also, putting work on a logarithmic scale reduces the influence of tasks that take a long time. At the same difficulty and usefulness, a shorter task should be considered more productive. At equal usefulness and equal time, a less difficult task should be considered more productive. These rankings are only achieved if I use the log function. Any thoughts on these results? Have you started collecting data? Here is a bit of data from three days of “work”… I am a Master’s student and am just starting to write my thesis, so my work consists of reading, writing, research, procrastination, etc.

Day 1
Task | Usefulness | Difficulty | Time | Productivity
Planning | 4 | 3 | 15 | 2.4
Trying prod. formulas | 2 | 4 | 120 | 0.7
Solved math question | 1 | 8 | 135 | 0.3
More on prod. formulas | 2 | 4 | 60 | 0.8
Installed soft. imported i | 5 | 4 | 90 | 2.0
TOTAL productivity = 6.3
avg. hourly productivity = 1.3

Day 2
Task | Usefulness | Difficulty | Time | Productivity
Planning | 4 | 2 | 15 | 2.7
Fixed comments, form. | 7 | 4 | 90 | 2.7
PDF settings LaTex | 4 | 3 | 45 | 1.9
Wasted time online | 2 | 1 | 45 | 1.2
Wasted more time | 1 | 2 | 30 | 0.6
Continued formulas | 7 | 4 | 150 | 2.5
Unaccounted time | 0 | 1 | 45 | 0
TOTAL productivity = 11.6
avg. hourly productivity = 1.7

Day 3
Task | Usefulness | Difficulty | Time | Productivity
Email for meeting | 7 | 4 | 30 | 3.4
Wasted time online | 1 | 1 | 30 | 0.7
Planning | 5 | 3 | 45 | 3.0
Fixed intro, objectives | 9 | 6 | 90 | 3.3
Found and read manual | 5 | 3 | 60 | 2.2
Played with some data | 5 | 4 | 60 | 2.1
Unaccounted time | 0 | 1 | 135 | 0
TOTAL productivity = 14.6
avg. hourly productivity = 2.1

The idea of multiply the attention required by a task and the time it takes (the a*h denominator) is definitely similar to the physics notion of work -- which maybe means we're onto something. It would be great to hear a bit more about your data collection and experiments too. I'm curious about the choice of the log function. Thanks for pointing that out Benjamin.

In my tests, difficulty and usefulness were ranked on a scale of 1-10 and time was in minutes. I am going to try this for a couple of days and see if the results make sense...

What about using a notion similar to the physics notion of "work" as a measure of force per distance? The "work" performed on a task is equal to the difficulty of the task (amount of brain power, concentration, attention, exertion) times the amount of time that that effort is sustained. Then you can either attenuate or amplify this figure according to the usefulness of the task. For example, running 5km and reading a journal article are tasks of the same duration and intensity, but one is (academically) productive and the other is not. Interesting post.

I haven't found any good tracking software yet (though I haven't really looked either). It would need to be fairly robust though: I'm thinking of a database model where you can enter projects and track related inputs and outputs over time at 15 minute intervals (or less?). Perhaps I'll try it next week, just with pen and paper and see where I get. But yes, defining an Atnu seems like a good first step. I think this is a job for AHP too and so we'd need to start by building up a list of tasks that can be pairwise ranked for attention requirements. Again thinking out loud, some examples might include: - Reviewing a journal article for journal <em>x</em> - Sketching out the idea for a new journal article - Preparing a journal quality figure - Preparing for a one-hour lecture If people can post these types of tasks as comments, then we can rig up a SurveyMonkey form or something to calculate some Atnu values.
