System Integration

Perhaps the biggest factor affecting System Integration (S.I.) is the partitioning of the system at design time.  System integration is all about putting bits of a system together so how the system is split up at design time defines what bits of a system are to be put together and thus what parts of a system need to be integrated into a full system.


The basic rule of thumb, when partitioning a system, should be high cohesion and low coupling.


If you have high cohesion and low coupling between the constituent parts of a system this will lead to little communication between them, little will pass between the constituent parts.  System Integration is about bringing the constituent parts together, if there is little communication between the parts this will make the process easier.  This can all be summed up by ‘Having as few boundaries as possible and as little information crossing these boundaries as possible’.


If, at design time, the system is partitioned such that the various constituent parts exhibit high cohesion and low coupling System Integration will be easier, i.e. quicker and cheaper.
