Lack of comprehensive and authoritative analysis of systems and management processes often leads to less effective implementation and the reduced efficiency of the entire organization. An essential part of this analysis is to identify the most important factors affecting the basic parameters and their measurement processes. The paper presents basic issues in identifying complex organisational systems, particularly measuring phenomena that occur in them. It includes both static (state identification) and dynamic (the identification of changes and processes) measurement factors. It also examines requirements for the scales of measurement used to characterise systems and management processes.
