In the early 20th century, management theories were devoted to the idea of 'one best way' to perform tasks, designed by the manager and implemented by direct reports. Like many things that must change with the passage of time, management styles evolved.

We've already seen how this change in approach has impacted construction today, but what does it look like in the future? As we look to the next 10 years, four factors will greatly influence the future of Lean: leadership, marketing in the field, multi-generational workforce and technology.
