Aw come on you guys, I know it's tough but you can do it!
I know that it might be really hard for some teams to express all that they need to in four pages, but it can be done. You may start off with ten pages. However, with the right editing you will be able to make a very powerful statement if you can get your point accross with fewer words.
A lot of professional writers have this problem when they make their first submissions. Their books are often several hundred pages too long. They have to cut, cut, cut, until they have a product that won't lose the interest of the reader (or the editor). (Not that I'm any kind of example with some of the log posts I've made.
)
Once you get the hang of it, you will figure out what is really important to get accross to whomever is reading your pages.
This could really become an excellent opportunity to sharpen your communication skills.
