IMHO big difference now is that management initiatives and technology deliver much more immediate feedback as to which strategies work and which don't. Today something like "Leadership 7.5" would never happen, due to the immediacy of both feedback channels and the Company's ability to pivot more quickly due to technology-enabled management techniques. These schedule disruptions are costly to DL in terms of money and reputation, but the solution has to account for current constraints in the supply chain and staffing and optimizing speed of implementation vs. investment.
