To implement kaizen in biotech, you need to follow a systematic approach that involves four steps: plan, do, check, and act (PDCA). This method of problem-solving and continuous improvement allows you to test and evaluate your ideas and actions. To use the PDCA cycle in biotech, start by defining your problem, goal, and customer value proposition. Analyze your current situation and identify the root causes of the problem. Brainstorm possible solutions and select the best one. Prepare a plan of action with a timeline and metrics, then execute it and collect data on the results. Compare your results with your goal and metrics to evaluate the effectiveness of your solution. If there are gaps or errors, identify their causes. Based on your evaluation, decide whether to adopt, adapt, or abandon your solution. If you adopt it, standardize it and communicate it to others. If you adapt it, modify it and repeat the cycle. If you abandon it, discard it and look for another solution.
