In the Netherlands, almost all people have dinner around 5:30pm. As a foreigner in that country, it is almost impossible to plan a (working) meeting around this time, which would be a `normal' time in many other countries. On the other hand, having dinner that early is not an obligation. No one will be ofended or would even care if you choose to eat later. This is an example of a shared strategy, i.e. an institutional arrangement where different actors have the intention of performing the same task at a certain time or setting. InMAS research, shared strategies can be a new way of expressing conventions that cannot easily be fitted into norms, individual plans or collective intentions, while sharing some elements with all of these.
