Team members don’t receive the same message. Customers are contacted twice for surveys by different teams. The situations for lack of co-ordination are legions.
The same solution for all these issues: evaluate and share the impact.
When a message is delivered, ask the receiver to acknowledge and reformulate a summary. Store and share this summary acknowledgement through the company repositories.
Transform the direction in a measure allowing self-evaluation. Infuse company objectives into department directives and key indicators. Allow departments to participate in the realization of common goals. Cancel objectives for which the implementation is detrimental to other department.
