I often get asked how many drafts a writer needs to do when writing a
 book. This is somewhat of a difficult question because writing is not 
about quantity but quality. However, no serious writer gets it right in 
just one take. You have to have the patience to review your work several
 times. Some authors suggest 10 drafts or more. I'm not sure that's 
really necessary, but it on your process and how you work.
When I'm writing for myself this is my process:
First draft: Just write to get it all down.
Second draft:
 Go back and smooth it out, add layers such as descriptions of people 
and places, personality traits, if it's in a real place maybe add names 
of landmarks, perhaps develop a subplot or side story, take a second 
look at dialogue, make it more believable or real.
Third draft: Let
 a writing group or trusted friend see a copy of the second draft and 
give constructive criticism. Remember that this is something you 
probably don't want your mom or significant other to do because the 
point of constructive criticism is not to hear 'that's nice dear," it's 
to get an objective viewpoint and make your work stronger. If your 
reviewer doesn't give you anything but praise, you haven't had an honest
 review. They don't need to be nasty or mean about it, but your reviewer
 should be willing to point out things that maybe weren't clear, 
dialogue that didn't make sense or sound real, or anything else that 
might occur to them. These people are not necessarily proof readers, but
 if they catch an error or two let them. Remember, don't get defensive, 
you are free to take or leave what they tell you. The point is to make 
your manuscript better. Then take the feedback and incorporate it into 
the book.
Fourth draft: Go over the book again 
with a critical eye. Make sure subplots are tied up as well as the main 
plot. Have you answered all hanging questions? Refine the dialogue 
again. Read it out loud to make sure it sounds real. Ask yourself if 
your characters would really react and act the way you've written them. 
Is the story believable? Editors have often told me the truth is no 
defense in writing. In other words, just because it happened in real 
life doesn't make it believable. Sometimes there are things that are 
just so crazy, that they are difficult for the reader to believe. In 
this case, you may have to do a little extra explaining to make 
something work. For example, if you're telling a story in which someone 
flies, they can't just start flapping their arms and take off. You must 
explain that they took a special potion or were genetically engineered 
to do it, or that just the way everyone on their planet is, etc. 
Fifth draft:
 Run your manuscript past another reviewer or set of reviewers. Listen 
to their comments and make any needed changes. Let it sit for awhile 
just to give yourself some distance.  Maybe a week or two, then come 
back, look it over again and fine tune it. Do a spell check, run it by 
your proofreaders. At this point, you may be ready to submit it. If not 
take more time to make needed changes.
When you finally
 become lucky enough to catch the eye of a publisher or agent, 
understand that while your manuscript is the best it can be at this 
point in time there will be more rounds of editing and drafts. The 
powers that be might want a new character added, or a few new scenes. 
Maybe they'll decide that it should be set at the beach instead of in 
the mountains. If it's non-fiction, they might want more explicit 
details in places or an extra scene to bridge a time gap. Sometime they 
want to change the title, which means key points in the book must be 
changed. You never know what they might want. Just be prepared to do 
additional drafts.
When I write for clients, I still 
use the same process. The only difference is they are not aware of it 
because I am not giving each draft back to them. My job is to make 
writing a book easy for them. They don't need to do the heavy lifting, 
so I don't bother them with every little detail. They don't need to see 
my first rough note marked up draft--which might not make a lot of sense
 to them anyway. Instead, they see things at the reviewer stages. When 
writing for others keep the process clean, simple and as streamlined as 
possible.
Finally, no matter if you're writing for 
yourself or another, always work from the same file. Don't pass multiple
 copies out to multiple reviewers or you will create a nightmare. You'll
 not only have to try to combine all the corrections, comments into one 
and inevitably miss something, but you'll drive yourself crazy thinking 
you've made a correction only to find out it's not there.  It wastes 
valuable time and energy. So work from one copy and give each generation
 of the draft a distinct new name to avoid mix-ups.
