The DECIDE framework was designed in 2008 by Professor Kristina Guo. It consists of six steps: defining the problem, establishing the criteria, considering the alternatives, identifying the best alternative, developing and implementing a plan of action, and evaluating the solution.

As you can see, it’s ironically very close to the scientific method, but it’s more practical and takes into account more complicated but equally interesting solutions before making a decision.
The DECIDE framework has in fact been originally designed for healthcare managers to make effective decisions in an increasingly complex work environment, where they need to juggle numerous medical, ethical, economic, legal, technical, and organisational concerns.
This is why using decision-making strategies can be helpful to guide our choices in a more rational way.
