To date we've been creating site plans, wireframes, copy outlines and
functional specs across a range of different document types (word,
Excel, Illustrator, Omnigraffle).
This has generally worked ok over the years, but we're trying to up
our game and rationalise the tools we use - specifically site plans
and copy outlines.
We were thinking that a simple content plan created in Excel listing
section, pages and metadata along with project status is flexible and
team friendly (anyone can update without specific software), but not
particularly client friendly regards an aesthetic site plan.
