Why did the Roman Empire grow so large and survive for so long? The Roman Empire lasted for 500 years in the west and then continued as the Byzantine Empire for another 1000 years in the east. At its peak the Roman Empire controlled approximately 6,500,000 square kilometers. There are few businesses today that could manage such a sprawling and diverse undertaking for so long without collapsing under their own weight.
From In Search of Excellence: "One reason the Roman empire grew so large and survived so long - a prodigious feat of management - is that there was no railway, airplane, car, radio, telephone. Above all, no telephone. And therefore you could not maintain any illusion of direct control over a general or provincial governor, you could not feel at the back of your mind that you could ring him up, or he could ring you, if a situation cropped up which was too much for him, or that you could fly over and sort things out if they started to get into a mess. You appointed him, you watched his chariot and baggage train disappear over the hill in a cloud of dust and that was that ... There was, therefore, no question of appointing a man who was not fully trained, or not quite up to the job: you knew that everything depended on his being the best man for the job before he set off. And so you took great care in selecting him; but more than that you made sure that he knew all about Rome and Roman government and the Roman army before he went out."
The key, it seems, was pushing autonomy to the lowest practical level. There is evidence that organizations that do this are able to be big but act small at the same time. Furthermore, people thrive when they perceive themselves as somewhat autonomous and demonstrate greater commitment when they are given discretion in how they do things. However, simply pronouncing that individuals have been granted autonomy is a formula for chaos, as the failure of many workplace empowerment initiatives have demonstrated. So how are we to give people practical autonomy?
The most important pre-requisite is a rigidly shared value system. Everyone must understand and be aligned with the organization's purpose and goals - why the organization exists and what its priorities are. Once the why and the what are clear, individuals should be allowed to exercise judgment and creativity in how things are done. Discipline around shared values provides a framework and gives people confidence to experiment based on stable expectations about what really counts.
Managers also need to demonstrate tough-minded respect for individuals by establishing clear accountabilities and mutually high-expectations. The organization should support this though frequent peer-reviews and a willingness to train, open dialogue and the sharing of goals, targets and performance measures, and by eliminating unnecessary complexity from centralized processes, systems, and organization structures.
The most difficult step for many managers is then giving-up the illusion of control by allowing individuals the freedom to do their work as they see fit, and then accepting the resulting messiness, overlap, and duplication.
The Romans may not have had much choice in how they managed given the practical constraints of the time. Today, we do have a choice. By establishing shared values and clear expectations we can provide the framework in which practical autonomy can be effective.
