Critical System Heuristics

What is Critical System Heuristics?

Critical Systems Heuristics (CSH) is an approach within evaluation theory that focuses on making boundary judgements explicit, or the assumptions that determine what is considered relevant within a study. CSH thus serves as a framework for reflection with which you can ask critical questions about the boundaries and assumptions within a system.

The goal of CSH is to make these assumptions transparent and open to criticism, so that different perspectives can be better understood and discussed. This is done through a set of twelve critical questions that examine the main sources of motivation, power, knowledge and legitimation within a system (e.g. healthcare system) or a single project. Answering these questions offers insights into the orientation of an intervention: “What is this intervention about?” Equally important is to assess assumptions surrounding the intervention: “What exactly does the intervention claim to achieve and what are the inherent limitations, that is, the assumptions and conditions on which the success rests?”

The core of CSH lies in promoting mutual understanding between the people or parties involved within the project. In addition, it helps to make visible how subjective choices and values influence how a situation is understood. This provides a framework for reflection and dialogue on the system boundaries that normally remain implicit, which can contribute to more inclusive and equitable decision-making.

CSH can be used in various situations, including:

• To analyse complex societal issues in which multiple stakeholders and perspectives are involved;
• When evaluating or designing projects and interventions;
• To identify and involve relevant stakeholders in a project or issue.

How to use Critical System Heuristics?

CSH is applied through the twelve so-called “boundary questions”, each of which relates to different aspects of a system. Figure 1 shows these questions. The 12 questions can be divided as follows:

• Sources of motivation: Questions about the interests and goals served by the system, and how improvement is measured;
• Sources of power: Questions about who makes decisions, what resources are controlled, and what external factors are outside the sphere of influence;
• Sources of knowledge: Questions about who is considered an expert, what knowledge is used, and where stakeholders can find assurance of success;
• Sources of legitimation: Questions about who is seen as legitimate stakeholders, how emancipation is promoted, and which worldviews are leading.

These questions are answered in two modes: the descriptive mode, in which you look at the current situation, and the normative mode, in which you investigate how the situation should ideally be. By comparing these two modes, you can gain insight into where there are differences and tensions between the current reality and the desired situation.

This reflection framework can be divided into the following steps:

1. Identify the system you want to analyse. This can be, for example, a project, organisation or policy initiative.
2. Ask the twelve critical questions from both the descriptive and the normative modes. This process helps to identify assumptions about the system, such as who is considered a legitimate stakeholder, what goals are seen as valuable, and who has the power to make decisions.
3. (Optional) Discuss the results of the questions with stakeholders. This can start a dialogue that leads to new insights and possible improvements in the way the system is organized and managed.

Completing the twelve questions with different parties stimulates dialogue in which the various perspectives of stakeholders emerge. By making subjective choices and values explicit, such as who is considered a legitimate stakeholder or which goals are seen as valuable, implicit assumptions become visible and negotiable. This creates a platform for reflection and critical discussion about how a system works and how it should work, fostering mutual understanding and collaboration. This makes it not only a valuable analytical tool, but also a practical tool to improve engagement and collaboration between different parties.

Example project on care systems for children in Sri Lanka

A good example of the use of Critical Systems Heuristics (CSH) can be found in a study about the healthcare of children in Sri Lanka.

The reason for the study was to develop and promote an effective reintegration process for institutionalised children. The research aimed to advocate for a better standard of care and better life chances for these children, so that they can fully integrate into their society when they leave the children’s homes. It is a complex societal issue, in which it is important to involve different perspectives, including those of the marginalised groups (in this case the children), and the power dynamics within the institutions that provide this care. CSH was applied here to analyse the existing structures within the care systems for children. The researchers wanted to gain insight into how decisions were made, who had the power, and how the interests of the children involved were served.

In step 1, the healthcare system was identified as the system that had to be analysed. Then, in step 2, the twelve questions were answered, looking at both what the situation was like at that moment (the descriptive mode) and how it should ideally be (the normative mode). This led to a thorough analysis of the power structures within the system and revealed assumptions about who the stakeholders were and what goals were considered important.

Step 3 involved discussing the results with stakeholders (e.g. childcare institutions and policymakers). This led to a dialogue about possible improvements in the way decisions were made and how to improve the care for the children. The use of CSH made it possible to make unspoken assumptions visible and encourage improvements in the decision-making and organization of the system.

What is the origin of  Critical System Heuristics?

CSH was developed by Swiss philosopher and systems thinker Werner Ulrich in the 1980s and described by him in “Critical Heuristics of Social Planning: A New Approach to Practical Philosophy” in 1983. It is rooted in systems theory, a discipline that deals with understanding and analysing complex systems. Ulrich’s work builds on earlier ideas by systems thinkers such as C. West Churchman, who emphasized how important decisions within systems often involve implicit assumptions. Ulrich’s goal was to develop a critical method with which these assumptions could be made visible and discussable, especially in social and policy-related contexts. Through his combination of systems thinking and practical philosophy, CSH has grown into an influential approach within evaluation and planning.
