Checklist Phoenix: Método que utiliza la CIA para resolver cualquier problema

Saliéndome un poco de la temática del blog, quería hacer alusión a algo que encontré hace poco navegando por la Red.

Se trata del método de la "Checklist Phoenix", o cómo afronta la CIA cualquier problema.

Realmente se trata de aplicar algo de lógica y orden ante cualquier problemática a la que tengamos que hacer frente de manera genérica, y bastante aplicable para los problemas informáticos a los que nos podemos tener que enfrentar los "IT Pros".

Extraido de http://bbh-labs.com/how-the-cia-define-problems-plan-solutions-the-phoenix-checklist

THE PROBLEM

Why is it necessary to solve the problem?
What benefits will you receive by solving the problem?
What is the unknown?
What is it you don’t yet understand?

Can you see the result? How many different kinds of results can you see?
How many different ways have you tried to solve the problem?
