Interconnections - the Bane of Complexity

Many software systems are complex not because they are large, but because they have many interconnections.

The inability to cleanly separate out components makes it difficult to divide a task between several programmers.

Complexity can only be managed by means of abstraction, by eliminating information that a programmer must know.
