Successful groups have great power, power to identify, understand the causes and implications of problems and opportunities, and come up with creative responses, and once moving can gather great momentum. Most workplaces are now actively seeking to harness the intellect and creative power of their employees and other stakeholders, and those that do it well create great opportunity.
The flip side is that groups also have inertia, they are much harder to get rolling than just an individual, and once rolling, have a tendency to take unpredictable excursions.
It is easy to underestimate the effort, leadership, and capacity to connect that is required to overcome this inertia, and to manage the momentum constructively, leading a group in a consistent direction, focusing on the important issues, and consistently delivering outcomes.
