I once worked for an organization known for providing good documentation. This is how it worked: They had a documentation-writing branch. And you (developer) knew that if you don't write documentation, they will. And then if will cost you _more_ time and frustration to review and correct what they wrote than to write it yourself and give to them. So you did write it (and they proofread it, corrected grammar etc.).
