A one hundred years arc of the evolution of effectiveness and success paradigms is introduced; starting with the Industrial perspective focused on Scale, giving place to the Financial effectiveness era, focused on Profitability, creating the innovation and funding fertile grounds for the Technology and Customer era, based on Differentiation, personalization and customization, which still is going on, but generation-defining disruptions gave place to a new era, the era of Purpose, where the imperative is to understand how we make our companies and ourselves resilient and prepared for disruption. In this environment, companies have been in trial-and-error mode, figuring out ways to be effective and win in an environment that is still fluid. Leading Success is a navigation map and a response to the challenges of effectiveness and success in this era. One where employees care for what companies stand for, and where they can affect change in the world to make it better while we make it profitable, to make it safer and cleaner as we succeed. They look at companies as places where the intersection of our values, our achievements, and the interests of future generations can coexist.
