The world of the manager is one of problems and opportunities. Problems are to be managed; one must understand the nature of the problem, amass resources adequate to deal with it, and "work the problem" on an ongoing basis.[...] But what if the problem can be fixed? This is not the domain of the manager.

An engineer believes most problems have solutions. The engineer isn't interested in building an organisation to cope with the problem. [...] And yet the engineer's faith in fixes often blinds him to the fact that many problems, especially those involving people, don't have the kind of complete permanent solutions he seeks.
