Hi, I have used excel for a project plan at work recently.
Unfortunately I can't send you across the document because tis work related but basically had first column with action points i.e. 1.0 and sub actions. Then The actions themselves in another column, then by column, responsibility, date to start, date to end, % complete, milestone y/n, comments. Once actions were complete I would shade in the row.
However as excel won't allow you to create a dynamic spreadsheet it only works if there aren't too many dependencies and you aren't adding in lots of additional actions.
