“Sixty-one percent of managers and 72% of workers do not trust their organizations’ performance management processes, according to Deloitte Insights 2025 (2025).” This lack of trust explains why so many business problems recur: root causes are not addressed and effective methodologies are not applied to solve them. Solving a problem is not about putting out a fire, but about building sustainable solutions that drive continuous improvement.
In any organization, from operations to quality and processes, the real challenge is not the lack of tools, but knowing which one is right for each situation. Choosing the wrong one can mean wasting time, money, and effort, as well as creating frustration among teams.
Below, we explore the main problem-solving methods, their advantages, limitations and the scenarios where they actually work.
Why is it so important to choose the right method?
Not all problems are the same. Some are simple and obvious; others are complex, multifactorial, or recurring. A poorly chosen approach can lead to spending weeks on an ineffective analysis or, worse, to wrong solutions that worsen the problem.
The key lies in identifying the level of complexity and choosing the most suitable tool.
