"Ready, fire, aim" is the more fruitful sequence if we want to take a linear snapshot of an organization undergoing major reform.
Ready is important; there has to be some notion of direction, but it is killing to bog down the process with vision, mission and strategic planning before you know enough about dynamic reality.
Fire is action and inquiry where skills, clarity and learning are fostered.
Aim is crystallizing new beliefs, formulating mission and vision statements and focusing strategic planning.
