The big picture is we have a weekly "experience exchange" in our development team. Each week we offer a topic we are prepared to teach for 3/4 of an hour. Then at the appointed time we pair up as teacher/learner for our weekly session. Over time it is expected that we spend about as many sessions teaching as learning.

At present the process is mediated by post it notes stuck to a wall. The script is intended to replace the post it note scrum and help ensure everyone gets a more or less equal opportunity to teach and learn.

So, a person can only be in each session once. For any session a person may be a teacher or a learner. There will only ever be teacher and learner roles. Each session includes everyone who is available.

The query at the heart of the issue is to find all pending session pairings an individual or group of individuals are involved in.
