Choose a problem you want to understand. Start learning where it connects to your life or work.
Six free courses are available now, one in each subject area. Each is self-paced, includes practical examples and self-checks, and needs no previous improvement training. Completion shows that you finished the course. It is not a professional certification.
See what the customer or next person needs, follow the work and identify avoidable waste. Choose a small improvement and check the whole result, including quality and effort.
Learn to ask why results vary and what evidence would help. Lean and Six Sigma can work together; the problem should guide the tools you choose.
