What is sub optimisation
This refers to a condition of non-fulfilment of the overall goal of a system. It occurs when the
objectives of a subsystem directly conflicts with the overall objection of another subsystem.
This means that the subsystems could be meeting their goals but the whole system could be
meeting its goals in substandard.
An example of sub-optimisation is where a factory might use high technology plant in its
operations but if as a consequence employees are neither expected to use any skill nor able to
work in a group with other, the optimisation of the technological subsystem would affect the
social and psychological structure and lead to inefficiency amongst employees. For example,
low productivity or poor quality; thus sub-optimisation of the factory system results.
