This is how Voyager was written.
The producer decides who gets to be the star of each episode for half a season. Rings a mate, asks for a pitch, and then puts their name on the white board that Writer X is going to write a character Y story that will be be delivered in the next 1 to 2 months. The producer makes 12 of these phone calls or has actual lunch meetings in the course of a week or two. So you have half a season being written by 8 to 10 different writers who are completely isolated from each other and have no idea what the others are doing.
When all those scripts are finally handed in, it's the Producer and the writers room job to rewrite those scripts so that they appear to have a consistent linear progression, while in general, just making them "better" and risen to the Berman standard of excellence.
A lot of good TV was made like this.
And I'm not saying that a good producer can't create the illusion of continuity from a hodge podge, but you know my feelings on this subject.
