What is PrOH Modelling?
‘PrOH’ Modelling is an abbreviation for ‘Process Oriented Holonic’ Modelling.
‘PrOH’ is pronounced ‘pro’ with a silent ‘h’ and rhymes with ‘show’ as in ‘show and tell’.
PrOH Modelling is a novel methodology developed from principles of soft systems methodology (SSM). It has been developed to help understand and change socio cultural technical issues in organisations, particularly issues that are holistic, systemic and complex, prone to dynamic change and impact on process performance.
Similar to other soft systems methodologies (SSMs) PrOH Modelling is used to explore opportunities for improvement that are systemically desirable and culturally feasible. PrOH Modelling enables modellers to elicit systemic success factors (SSFs) for change that will help improve process performance.
What is a holon?
PrOH Modelling produces human-centred models in holons. Holons are models of systems that are parts of larger systems and also have systems within. Holons can be joined together to form a set of models known as a holarchy. A holarchy can visualise hidden and emergent properties of socio-technical systems, subsystems and meta-systems in multiple layers.
What is a holarchy?
A holarchy of models is formed through refinement and abstraction of holons. In contrast a hierarchy of models is formed through reduction and aggregation of entities with inheritable properties. PrOH Modelling’s holonic properties makes holon-based modelling and the use of holarchies possible to build sets of models of systemic success factors in people centric organizational systems as refinement and abstraction allows for an accurate descriptions of different behaviours observed at different organizational levels that are not necessarily observed at other levels. PrOH Modelling is unique in being able to model holons and holarchies for organizational improvement.
What is the purpose of PrOH Modelling Methodology?
The PrOH Modelling Methodology works best in an action research context. When used in an action research context PrOH Modelling is able to make changes in practice to organizations, a contribution to general theory on the topics being investigated (e.g. digitalization, productivity) and a contribution to systems thinking methodology itself.
