Research the lean culture further. Explore the theoretical aspects, as well as the practical side. With a grasp of the origins of the lean culture, deciding how the philosophy will evolve will be easier. Indeed, according to The Interdisciplinary Committee on Organizational Studies, a big part of the lean culture as forged by Toyota is "kaizen," or continuous improvement, and your research process is an example of that principle. Read the books on lean culture from the past, then visit as many assembly lines and workplaces as you can to gather the widest frame of reference you can.
Analyze your data to shape your personal lean culture philosophy. This is, after all, the reason readers will choose your book. Decide what will help your readers the most while creating a philosophy that will bring your book the greatest attention. The concept of "lean culture" is a refinement of traditional business philosophy. Managers have always tried to eliminate waste, but, as the Wall Street Journal pointed out, the "Six Sigma" and "Toyota Way" philosophies created a framework through which both worker and boss could improve efficiency. Six Sigma is a methodology for measuring and improving a company's operational performance.
Introduce your unique lean culture philosophy to as many professionals and workplaces as you can. Even if you must serve as a pro bono consultant, putting your philosophy into practice will likely give you important examples for your book and show you where you must adjust your thinking. Creating a book can be an isolating experience. Business is a collaborative effort, and refining your philosophy in this manner can provide you with what the Toyota Way calls "hansei," or relentless reflection.
Compose your book, writing each section one at a time. This will keep you from feeling overwhelmed by the task of writing a book. Alluri Raju of Steelwedge Software reminds you that collaboration is a vital part of a lean philosophy, so submit your first drafts to friends and colleagues for their suggestions. A book forged in the fire of the lean philosophy has a good chance of reflecting that philosophy.
Verify that your personal take on the lean culture is present in the draft you have written. There are many existing books about becoming "lean," and most businesspeople intuitively want to reduce waste. What will likely make the difference is the new, creative and powerful way you teach people to think, act and work "lean."
