Sure the problem solving success come from the complexity of the problem. This count for 50% of the solving process. So, if people could master the remaining 50% of the solving process, they would have the feeling and motivation to be able to solve all the problems. That is possible with a clear guidance on: 

• How to approach, understand the problem  
• How to describe, interpret its possible/potential consequences 
• How to build responses to each consequence to minimise the risks 
• How to definite alternative solutions 
• How to implement and control the application of the solutions.
