Pull Schedule - everything?

So its commonly accepted that pull scheduling is efficient, quite a lot more than push scheduling. If we look at it from the information network perspective as I brought up here http://gamesartdesign.blogspot.com/2009/02/productivity-as-information-network.html previously it appears as if there is a general trick to it.

User Value and its derivates pulls development from the team. The derivates of user value is in this case stuff like product vision, strategy, audience, test feedback and such.The whole team process the User Value requests as a unit. Each team member is always ready to have information pulled on request from the team.

To avoid getting interference from management the team is likely to benefit from keeping track of progress towards the User Value derivates. Post it on a wall and update continously so this information dosnt become a burden to deliver.
