Beginning at the end.

When a particular solution state is clearly defined, a problem can often be more easily solved by starting with the solution and working backwards toward the problem, filling in the necessary steps along the way.

The classic example is the problem:

Divide a triangle into three parts so that the parts can be put together to form a square. Thatâ€™s very hard. But if you start from the solution end, with a square, itâ€™s easy to divide it into three parts all of which form a triangle.

How do you count the number of people in a stadium thatâ€™s over ninety percent full? Count the number of empty seats and subtract from the number of seats in the stadium. Easier than counting people.

Start at the end, with the solution, envision how you want the relationship to be and work backwards toward a discovery of the problem.

Whenever the solution or goal state is clearer than the problem, then changing the entry point to the end may be the best approach. Start with the goal or solution and look for ways to work back to the problem.

For our example starting at the end could mean you envision how you want the teamâ€™s performance to improve or how you want the team to play in the upcoming match, this could give you the timeline needed to form a strategy.
