The classic theories are based on the scientific and rational view of the companies, of management systems and on the scientific organisation of the work, premises under which it is assumed that employees are passive subjects whose performance may be totally controlled by formal mechanisms. Contingency theory is based on the premise that no control system is applicable to all organisations and all circumstances, but rather that it depends on each organisation’s specific circumstances, whether in relation to its environment, technology used, type of organisational structure, competition, management style, etc. Furthermore, it has been proven that mechanistic systems are characterised.
