Second strategy: negotiation

But in some cases, it is not always possible to predict and trying to plan can lead to an inefficient strategy. Henry Ford used to say: "People can choose any color for the Ford T, as long as it's black". But nowadays people choose in more diverse ways and it becomes difficult to make choices after the event.A second strategy was developed to treat poorly predictable situations where resources are scarce. It's negotiation. The choice is then made in the present. It is the case for example of market economy which understanding was widely developed 150 years ago. The biding of a price occurs during the negotiation between supply and demand.

There is great debate as to whether it is better to choose the planning or the market economy, not only within states but also in the functioning of communities or businesses. Is it better to predict or choose every moment according to a negotiation? The best strategy depends on the conditions in a given situation and it may be interesting to have a thorough knowledge of the different possible strategies to choose the most efficient for a given situation.
