We don't have a church program but our order of service usually flows something like this:
Announcements
Praise & Worship (1 or 2 songs)
from there, it's a free for all...but generally from there it'll go from P&W to
Harvest Time (most churches call this Tithes & Offering) (song)
Choir Selection
(if the choir is really good that day, this is the part where the usher that looks like Carl Winslow from "Family Matters" will get his first Shoutin' Lap in around the sanctuary)
Altar Call/Sermon (the order in which this happens varies from Sunday to Sunday...sometimes with more than one praise break sprinkled in there somewhere...and the Carl Winslow usher will get Shoutin' Lap #2...#3-#5 also if necessary)
Invitation
Visitor Recognition
Benediction
