When you want to encourage people to think about significant progress.

Ask them a set of structured questions which get them thinking (and possibly acting too).

1. Get the people into a workshop. Create four columns on the wall, in a document, or in a virtual whiteboard: "G","R","O" and "W".
2. As the facilitator, ask lots of coaching style questions. Ensure the workshop participants brainstorm each area fully, in sequence.
3. Goals = get them to consider what they want to achieve.
4. Reality = get them to consider where things are now.
5. Options = get them to consider what the options are.
6. Will = get them to consider what they will do.
