The scientific method is a process of research where a problem is identified, relevant data is gathered, a hypothesis is formed based on the collected data and the hypothesis is tested. If the theory proves to be false the cycle repeats. This method is the foundation for both continuous improvement methods PDCA (Plan-Do-Check-Act) and DMAIC (Define, Measure, Analyze, Improve and Control) with the addition of countermeasures to improve the designated process.
