BCS debate focuses on complex systems  The UK engineering
population is currently unprepared for large-scale, complex IT
projects, Stuart Jobbins from Rolls Royce told attendees at a
recent BCS Thought Leadership debate.  Definitions of complex
systems have to incorporate the numbers game. The higher the
number of technical parts and people involved, the more likely a
system is to be complex. With complex systems, one can see the
final result, but it is becoming increasingly difficult to see
or understand the inner workings of such a system, attendees
heard.  From a real-time-controls perspective, complexity jumped
in the move from linear (continuous) systems, with their
inherent constraints, to the realisation of these systems by
digital construction, which allowed us arbitrary and
discontinuous relationships. This was the liberating step for
flexibility - but the precipice with regards complexity.  There
is complexity in requirements, as well as within the IT systems
themselves. Therefore, there is a need t
