What's the best way to divide responsibilities when it comes to planning services?

We currently have a Worship Coordinator.  (Job Description available if you email me.)   Her job is to "coordinate" the myriad of tasks and teams related to worship.  E.g. She organizes the music team, but does not regularly play or sing.  She finds readings/prayers/litanies AND finds a variety of people in the congregation to do them.  She gathers the trumpters, violins, flutes when various songs demand those sounds.  She schedules the regular musicians, e.g. band, piano, organ.  She makes the weekly powerpoint.  She lays out the worship order.  She leaps tall buildings in a single bounce!  You get the idea.

The Worship Coordinator is an integral part of our small staff (6 total).  She meets regularly with the Pastors to understand the needs of the congregation and the upcoming plans for preaching.  She meets and emails several times each week with the preacher of the week to coordinate the details of the service.  Song choices are essentially up to her, but are often made in collaboration with preacher and musicians. 

We used to have 3-4 teams of worship planners who met with the preaching pastor every 6 weeks to get a sense of upcoming services.  Then they divied up the services among the teams.  Each team was responsible for selecting songs and other worship parts.  This had the benefit of using more people in leadership, but the problem of no consistency and no one to look after the ongoing administration of worship, e.g. CCLI licensing, piano tuning, worship bulletin, etc.

Seven years ago, the church made an overhaul of the entire leadership system and, as part of those changes, they decided to hire a part-time Worship Coordinator.   My opinion is that we have the best of both worlds:  a single point person for many of the tasks of worship planning, but a person who invites communal participation and honors the ideas of others in the planning process. 

I've been part of five different churches worship systems and this is by far the best experience.  Trouble is, it's only partly due to the system.  It is mostly due to the integrity, intelligence, abilities and spiritual maturity of the person God provided to be our Worship Coordinator.  (P.S.  She is NOT available for hire!)  

Joy, our worship director just left and I'm intrigued by what you describe.

So far, our worship leaders have led the praise band and led our worship during the services, as well as coordinated the planning, etc., that you describe above. I can see where it can be difficult to find that creative musician-praise-team-leader who is also good at planning and organizing. But we want both -- of course. :)

I'm wondering: What about the person who actually leads the worship during the service? Is that your pastor in your church, or is there someone in the praise team who introduces the songs and makes the transitions during singing, readings, etc.?  Is that praise team leader a paid position?

There are sample job descriptions on the CRCNA site.  Connect here and go down about 2/3 to the section "Employment Issues: Job Descriptions."  There are two specifically for Worship staff positions.  

Thanks, Joy!
