Process Oriented Holonic Modelling Methodology

A community of systems thinkers

The website has been established as the definitive source on PrOH Modelling for PrOH Modelling Methodology users.

The website contains tools, case studies, links to academic works and games based on the PrOH Modelling Methodology. It also contains an application to assist users to process data and draw PrOH Models. is a not-for-profit community founded to benefit the use and development of PrOH Modelling, PrOH Modellers, the beneficiaries of PrOH Modelling applications and to further systems thinking and action research theory.

‘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 type of soft systems methodology that is used to enquire into and improve complex systemic organizational process problems. As a soft systems methodology PrOH Modelling emphasizes understanding, definition, consensus building and action taking to solve problems. It is particularly useful in processes that are dependent on lots of human activity and decision making, have a high degree of subjectivity and have numerous different stakeholders with diverse backgrounds and opinions. PrOH Modelling is best used in an action research or intervention based context where a researcher is an active participant in organizational strategy and operations and is able to maintain an independent and objective perspective.

The website exists for the community of PrOH Modellers. This includes those who wish to use it for academic research projects such as masters dissertation or doctoral theses, those who wish to use it for change projects in their own organizations, or in a consulting capacity in other organizations. We also welcome users to develop the method and share new case study examples with the community.

How PrOH Modelling works

Play Video

PrOH Modelling works because it is a soft systems methodology that has simple rules and guidelines that can be applied to a specific type of activity: which is to investigate and resolve complex systemic process oriented challenges. PrOH Modelling give visually appealing models that have very little codification and are ready to be used in presentations to managers. PrOH Models can be easily produced in non-proprietary software although new software using artificial intelligence can be used (PrOH Modeller).

Other comparable approaches can be more conceptual and hence more difficult to comprehend, they also have wider applicability in general problem solving making them less useful to for the investigation and remediation of complex systemic process challenges.

Why PrOH Modelling

"In addition to delivering improvement projects PrOH Modelling can develop your professional and personal skills. These include: enhanced investigative skills, objectivity and rationalization of thought, increased ability to process qualitative data, better presentation skills, and more effectively dealing with people, personalities and conflict in systems. You will develop transferable skills to be able to work across a variety of sectors in manufacturing and services of all sizes.

Professor Ben Clegg


“PrOH Modelling is an advanced methodology designed to understand and enhance complex organisational systems. Using this approach, we conducted participatory action research in a variety of organisational settings which led to profound changes. PrOH Modelling encourages collaboration and inclusivity, allowing all stakeholders to actively participate and contribute to transformative efforts. PrOH Modelling is rigorous yet practicable and delivers impactful change to current organisational processes and practices”.
