Laura Nash's 12 questions

The method works a problem or a decision through ethically.

It lets you judge whether a decision being introduced is sound, or prepare your own position and the arguments for it.

When to use it

1. When a decision has been taken, or is about to be, and you are one of the people it affects.
2. When you are taking a decision and want to think about how the people it affects will take it.

When not to use it

1. When the decision has to be taken anyway — because the organisation's survival depends on it, say.
2. When the decision reaches one person, or a handful.
3. When the decision has nothing to do with changing how people behave.
