About Separate Writers Strategy

It was noticed at the lecture that many use for example Word document in groupworks
document writing. In my case, many of the documents that are done in groupworks, are written so that the group decides what and who writes and then the actual writing is done individually in different places and time. In Posner's paper [1] this is called separate writers strategy. Here I'm going to discuss a little about the separate writers strategy in a situation where the document isn't handled in one place and time.

Good side in separate writers strategy in my opinon is, that everyone can write what is agreed when ever they wan't (of course keeping in mind the deadlines). That's also sometimes a bad side, since the written text is often depended on earlier text. Waiting for others might not be nice...

After everyone have written their part of the document, someone should review the text. It is sometimes hard to follow which text part should be where and it is someones duty to add all the text together and make everything sound fluent (different writing styles often occur..). This problem with lacking uniform style was noticed in Posner's study [1]. It is said in the paper that "Following the separate work there still remains the need to unite the resulting segments in order to create a uniform style.". That creates more work and who should do the uniting?

I think that the relationships between the writers has an influence in the writing style.  Posner's study also says that separate writing can be effective when writers understand one another. Posner's paper presents an example of a pair of researchers who had a long history of working together. They had all details clear when they started to write and they send the document back and forth and gave feedback to each other. I think that it shows how the document shaping can happen fluently when writers know each other and have a history together. Giving feedback might be easier.  I have also noticed that writing a document with people I have worked with earlier, is more fluent and maybe the sharing of work is more easier to decide.

Here are some of my thoughts, what are yours?
