Good philosophy for running meetings:

You have to be careful if you don't know where you are going,
because you might not get there.

Time, Interaction, and Performance (TIP): A Theory of Groups

Grath, Joseph E. Time, Interaction, and Performance (TIP): A Theory of Groups. In Small Group Research 22 (2), pp. 147-174. May 1991.

The main point as I see it is that studying group behavior is hard. Most traditional studies are invalid because group dynamic studies that hold some activities constant influence the study because group activities are interdependent and concurrent. In other words, taking a group activity out of the context provided by the rest of the group activity context invalidates any observations about that activity.
            The paper explicity states this as "Most systems of observing and coding interaction processes ... are built on the implicit assumption that a given act has the same meaning (in terms of the coding system being used) no matter who performs it and no matter where it occurs in the group's activity. " ...and this paper is just as guilty as it ignores all lobbying that goes on before and after meetings happen in my NSHO...
             Of the eleven propositions presented, proposition 7 seems to have the most insight: "One major form of temporal patterning is social entrainment. Entrainment refers to synchronization (temporal
condition) of phase and periodicity of two or more processes." Think of this as the "cue ball"effect. Events on a pool table are synchronized when the cue ball is hit such that some rebounding ball will sink another ball into a pocket (hopefully). Group behavior in this paper is viewed much the same way, where the focal point of the meeting is "sinking a ball in the pocket" and the various "ball collisions" are the temporal events deliberately synchronized to obtain this event. In this light, sinking a ball with many balls on the table will require a completely different shot than if only one ball is on the table. This is the idea behind TIP, social entrainment, and the importance of including context in group behavior studies.

Communication Modes and Task Performance

Short, John, Williams, Ederyn, and Christie, Bruce. Communication Modes and Task Performance. In The Psychology of Telecommunications, pp. 77-89. John Wiley & Sons. 1976.

Key insight from this paper, in my opinion, is that problem solving for telephone conversation and other media "at the level of the processes leading up to the final solution, effects can be observed ... [but] no effect on the [final solution] will be observed." This is in agreement with the above mentioned TIP theory where paths to goals will change as group dynamics change, but people will learn new "entrainment" processes to achieve the final result.
          However, it was pointed out in class there are certain kinds of visual problems which are not solvable over the phone. This is in agreement with what I suppose is the leit-motif of the paper:  tasks which are best suited (and least sensitive) to multi-media are "tasks which would be insensitive to medium of communications (tasks with little need for rapid feedback about the other person's reactions). "
          The paper observed "the usefulness of a strange system such as a closed-circuit television might therefore be expected to increase with experience." In accordance with their theme they also observe when "Information transmission does not require a close interpersonal relationship to be succesful, then we will find no effect of medium of communication for such tasks is likely to be confirmed."
           There are also dramatic tradeoffs with using different mediums (supporting the notion of learning new entrainment per new medium). The salient supporting fact was "despite observations that the impact of the spoken word is as great or greater, comprehension is generally found to be greater with the written word."
