There are two basic models for how information gets to the people who need it: Push and Pull.
The push model is where the owner of the information contacts and shares it with those who need it. The information can be shared corporately (in a meeting) or individually (email, hallway conversation). It places more responsibility on the information owner, as he/she needs to be fairly knowledgable about what each team member does and needs in order to get the right information to the right person on time. It is essential in situations where your team is very small and things are happening in real-time. For example, if I learn that my pastor is going to invite a guest on stage with him in the greeting (which begins in 30 seconds), I quickly determine that this affects audio, lighting and video and use my com system to immediately pass that information along to those people so that they can prepare for this audible.
In a project environment, however, this model has serious shortcomings.
Pull is when all project information is put in an central location and then those who need information can go there and retrieve what they need. The location can be physical or virtual, as long as all team members can easily access it. An old school example of this would be a theatre call board. The stage manager would post information by a specific time each day and all cast and crew would check the call board each day. Notices include changed call times, rehearsal room assignments, costuming notes, etc. If it was on the call board, you were responsible for the information. The internet makes this method available to us all and in a project environment is a far superior method for the distribution of information. There are a myriad of tools: Google Groups which is free but has limited features or Basecamp which is fee based but has a great list of features are just two examples. Planning Center (which most of you already use) is an outstanding example of a Pull system. You put the information out there and anyone who needs it has access.
The Pull system has is downsides – if you used meetings as team building time, you will need to be more creative as meetings become unnecessary for the exchange of information. It also gives a level of ownership and responsibility to people who may not be accustomed to having it and that may be a learning curve as you move from one method to the other. However, the upsides to a Pull system are many.
I would urge you to look at how information flows in your team. If you are still using a push system, consider making the shift to a pull system. It empowers team members, creates less burden on leaders and once fully implemented, will lead you to a more cohesive, highly functional team.
