As you plan an event, it is important that lines of communication be kept open between leaders, between leaders and servants, between leader(s) and the church office, between leaders and the guest speaker/worship leader, and between leaders and the contact for the venue where the event will be held.
In this day and age, we need to find the method of communication that works best in each of those scenarios. Do you need to communicate by email with your church office and the venue? Do your leaders respond best to text, phone or email? When is a face-to-face meeting best? Do you need a paper trail? Do you need to communicate the same message to a number of people?
I guess I’m old-school because I still like email–I like the written letter or message, where I can print it out if necessary, and look back at what was actually said easily. But I have young women I contact who look at their email very infrequently, and if I need to get a quick response from them, I need to text them.
Make sure there is a meeting of the minds when it comes to communication. Retreats (and other events!) require reliable communication.
