The best process is one that everyone will use and improve of their own accord, because it helps them to achieve what they want:

• Agency – to make their own ‘me-shaped’ dent in the universe.
• Mastery – to learn and master new skills.
• Autonomy – to be free to choose how they make their dent.
• Purpose – to do this for something bigger than themselves, that has meaning beyond the sale.
• Community – to do all this with ‘people like us’.

The easiest way to achieve that is to involve them in its design, right from the start.
