I hope someone out there can help me because I am wracking my brain trying to remember this technique used for knowledge capture.

I think it goes something like this...

After an activity participants are put through a series of interviews gathering their perspectives on what happened. This is then written up in a two column format with the  participants comments in the left column and analyst & 'manager' comments in the right.

I think this technique has the word 'history' in it's name but I cannot recall it with any certainty.

Can anyone help with reuniting me with my lost technique?!?

Thanks

Cory Banks
