Contingency school

I had a question related to the contingency school. The idea behind the contingency school is that there is no best way to solve a management problem. Depending on the situation, people who subscribe to the contingency will change their approach. In other words, this chool promotes two things:

a) an awareness that adapting to a changing business environment is very important

b) a flexible mindset

For example, imagine a company that is involved in on-line advertising. Maybe, their approach is very process-orientated. However, as the company grows bigger, the CEO realises that there is less and less communication between the workers. This new situation (a bigger company) requires the CEO to use a new approach (for example, more team building activities) that the company never did in the past.
