According to drastic change around the world, I learned a new lesson from COVID-19: We need a new revolution approach like metaheuristics methods which are useful for NP-hard problems, for leadership as well. Now we know how huge changes can happen quickly and we need much more agility to make a sustainable management system and how the business environment can be changed and affected by some causes and create NP-hard problems for business.
Biomimicry and TRIZ are perhaps non-quantitative metaheuristic methods.
Instead of looking for more complicated problem-solving methods, we might consider solving all of the uncomplicated (but not simple) problems in the world using data, control charts, Pareto charts, histograms and Ishikawa diagrams. Agile approaches to quality improvement could make massive headway on these kinds of problems in 18-24 months. Maybe after we've taken all of the “easy shots” there won't be so many complex ones left.
The countermeasures for COVID-19 are simple and well known: wear a mask, wash your hands, stay out of crowds and get vaccinated. We don't need complicated analysis to solve this problem. But like all quality improvements, compliance with countermeasures is rarely uniform.
Thank you for your consideration and reply. I do agree with you we should focus on simple methods instead of more complicated. The concept of all meta-heuristics methods are very simple like ant colony optimization and AI or genetic algorithm, but a huge different in results. Some simple aspects can make a huge changes on business.
