Sharing perspectives, quality and KJ-technique

by Lilia Efimova on 12 May 2004

Why blogging is about quality? Because perspectives are shared:

Back in the late 1970’s, the US government commissioned a study to look at effective group decision making. In the study, they asked 30 military experts to study intelligence data and try to construct the enemy’s troop movements.

Each expert analyzed the data and compiled a report. The commission then “scored” each report on how well it reported the actual troop movements. They found that the average military expert only got 7 out of a 100 elements correct.

Each expert then reviewed all of the other experts’ reports and rewrote their initial assessment. The average accuracy for these revised reports was 79 out of a 100.

What was different between the first report and the second? The experts didn’t have any new information. All they had were the perspectives of the other experts. When they added those perspectives to their own, their accuracy increased ten-fold.

The quote is from The KJ-Technique: A Group Process for Establishing Priorities found by James Robertson. This technique seems to be interesting to consider in a combination with Open Space method for BlogWalk meetings (pinging Ton and Sebastian).

We’ve developed a webapp that allows teams to perform K-J techniques – live brainstorming, and I thought it might be relevant for you and your readers if they wanted to try it out with their teams. Let me know if its useful!
