We stop pushing things as they are and focus on how things can develop. These questions are concerned with how to get from the present situation towards a more ideal situation. As future alternatives take form, they are examined. Often the vision is partial but people are able to identify pieces that need to change. Later these specifics can be worked into a cohesive whole.
Some people prefer a visioning process before asking specific change questions.
These questions examine the alternatives that come from the vision and ways things need to change. There are many ways to get to any goal. If a person is only examining two alternatives maybe more feeling work needs to be done. Be sure not to give more time, enthusiasm, or focus to any one alternative even if you think it is the best. Also search out alternatives that seem on first glance to be odd or unusual.
