More simply: don't outsource activities that have a complex interface to your organisation. Having to write complex specs for an outside organisation to implement is an anti-pattern, because: - the more complex a spec the harder it is to write and understand - there's potential for endless disagreements / lawsuits on what was actually promised and delivered - the overhead of having a complex spec that must be understood by people in both orgs.
