Ignorance, mediocrity, and mistakes run rampant when organizations fail to link the right people to the right information at the right time. But, if your organization has a bit of excellence, a "pocket of goodness," how do you spread it to others?
The short answer is: teach a class, coach key managers, "infect" a few colleagues and a new positive culture will spread.
A pocket of excellence is developed or uncovered, the people who know how to do it are connected to people who need to learn it, and new and presumably better ways to "cascade" throughout the system.
Making a core team accountable for ensuring that the right links are made and that the right facts and feelings are kept flowing through the right connections can make all the difference between success and failure. Performance coaching by a core team keeps information, guidance and motivation flowing in the network. The team continues to find and groom dedicated helpers so that they aren't burdened with every detail of the "connect and cascade" process.
No matter how much time and money a team has, scaling depends on a chain reaction where the core team doesn't have to go in and personally push over each tile in the chain of domino's. Think bad to great, not good to great; for excellence to spread.
