I used this fairly basic but highly effective method of project management to work out how to get a rather large website live within a few weeks. It was a daunting prospect but once it was all on the wall it was suddenly manageable.
This is also a great way of flowcharting processes that you’re developing. In fact, I once used it to flowchart the entire production and sales processes of a web firm.
Just move the sticky to a different location. You’re really only limited by your imagination for the uses of this method.
