Can business outcomes be unrealistic or unattainable?

In certain cases the business outcome identified may never be achieved (e.g. no traffic accidents in the city).  However, focusing every person, every job, every decision, every implementation on contributing to that outcome can go a long way to improving the situation.  The service measures (e.g. the number of accidents, the severity of accidents, the occurrence of accidents) are monitored along with service levels (e.g. reduce accidents by 10%, reduce severe accidents by 10%, reduce the occurrence of accidents at certain locations by 15%).  However, the focus is still on how to eliminate all accidents.

This type of business outcome can promote collaboration between various parties (e.g. the police, the road planners, the transit authority, the EMS service, the insurance companies).
