Is there a more effective framework for teaching writing?

There is a program in elementary schools is called 6 Trait writing developed by NorthWest US educators (see: http://www.thetraits.org/about). It was developed to replace a simple grading system and provide teachers with a more effective method for evaluating and giving feedback on student writing.

The traits are: idea development, organization, word choice, voice, and sentence fluency. Here you can find definitions: http://www.nwrel.org/assessment/definitions.php?odelay=0&d=1

I am just now looking into this system to figure out how I might use it as a framework for my own training of business and legal professional.

But I want to share it with other trainers and perhaps generate some conversation on this.
