Managing cultural change involves the hard of building what David Lax and Tim Sebenius call “winning coalition” —coalitions whit the power to take action and the robustness to survive inevitable opposition and crises. —often leaders must also forestall the formation of blocking coalitions by those seeking to seeking to protect the status quo or lead the organization quo or lead the organization down a different path . Inevitably, there will be preexisting coalition that came into being to supper the old leaner or to resist change during the old regime. All these challenges require figuring out who will offer support and who will raise opposition. This task in turn is inseparable from one’s efforts to learn, gain early wins, and develop a compelling personal vision. Coalition building should be well under way by winning coalitions to help achieve the goals of the first era.
