Complex Systems Design – How Users' Uncertainty Can Create New Opportunities
Complex systems are like a world. A small quantum world, full of elements moving simultaneously in different directions, with dynamic connections that change according to context, and with unexpected influences that can lead to disruption or exceptional success. One of the central problems in these systems is uncertainty, an aspect that designers often try to alleviate through analysis, tools, and predictions. However, sometimes, instead of trying to predict things, uncertainty can be viewed as an opportunity to create a better user experience. In this article, we explore the question - how can complex systems design use users' uncertainty as a strategic tool to create more flexible and enriching systems?

Uncertainty in Complex Systems – What Does It Mean?
Complex systems are characterized by numerous parameters, variables, and ambiguities, which can arise from several sources:- Unpredictable User Behavior - Users often use the system in ways that were not anticipated.
- Rapid Changes in the Environment - New regulations, advanced technology, or unexpected competition.
- Diversity Among Users - Complex systems serve different audiences with conflicting needs.
In companies and ventures operating in constantly changing environments (in terms of the number of users, their needs and goals, technological conditions, etc.), uncertainty becomes a central and inseparable part of the design itself, especially when every decision affects millions of users. In such cases, the main challenge is not only to deal with the changes themselves but also to design systems that can adapt in real time while maintaining a consistent and complete user experience.
Principle of Uncertainty in Complex System Design
Instead of trying to "control" the system, it should be recognized that uncertainty is not an obstacle but a natural characteristic of complex systems. The important question is how to turn it into an advantage and leverage it for defining and designing flexible, efficient systems tailored to changing needs. From this arises the need to formulate principles that use uncertainty as a practical tool, from which value can be derived, for example:- Do Not Treat the System as a "Collection" of Features - A complex system is not just a collection of separate functions; it is a network of dynamic relationships, where each component influences others and interacts with them continuously. Focusing solely on the features themselves can lead to a scattered or uncoordinated design. Instead, it is essential to delve into the dynamics between components – how features work together, how users experience transitions between them, and how any change in one component can affect the entire system. This approach enables the creation of a holistic and transparent user experience, where the system functions as a single entity rather than a collection of isolated solutions. For example, in a project management system, the focus should be on the flow between planning, tracking, and reporting, not just on each tool or module individually.
- Improve While Moving - In complex systems, uncertainty requires not only creative solutions but also an approach based on trial and error. The system must be designed in such a way that it can "check itself" continuously – collecting data, analyzing results, and deriving insights in real time. For example, designs that allow for built-in A/B testing, dynamic adjustment of interface components, or predicting user behavior through machine learning. This way, different solutions can be tested, the system can understand what works best under changing conditions, and improvements can be made continuously, reducing risks and enhancing the user experience.
- Allow Autonomy and Local Decisions - In complex systems, where many users operate simultaneously and sometimes independently, it is important to allow each user local control over their personal experience. This means designing systems that empower users to make decisions tailored to their needs and circumstances without relying on central processes or decisions from other users. This approach not only reduces the feeling of uncertainty but also increases the sense of control, independence, and engagement of the users. This is especially critical in complex and dynamic environments where generic solutions don't always fit every scenario.
- Understand the Dynamics of Confidence within Uncertainty - Uncertainty does not have to lead to chaos or confusion. In fact, in complex systems, there is an opportunity to design frameworks that provide users with a sense of security even in changing and dynamic environments. This means creating a clear system where users can understand the structure of processes, recognize the next steps, and know how to respond to changes that occur. Users must understand at which stages their data is protected, how the system reacts to errors, or what the course of action is in case of technical issues. Creating a sense of security doesn't mean providing absolute certainty about everything but offering users clear courses of action, guidelines, and ongoing support, so they feel in control even when other conditions are unpredictable.
- Create Clear Anchors - The principle of a clear anchor is based on the need to provide users with a fixed and understandable starting point at every stage, even when the rest of the system changes. In complex systems, where many parts may be updated or change in real time, clear anchors help users understand where they are in the system and what options are available to them. These anchors will allow users to maintain orientation, even in environments that change frequently, and will help them feel in control, even when not all information is available or stable.
- Immediate Feedback Mechanisms - Users in complex systems need to see the impact of their actions in real time to feel in control and prevent confusion or helplessness. Immediate feedback mechanisms provide users with direct responses to their actions, whether it's confirmation of a performed action, an update on a status change, or a new result received. This allows users to immediately understand the consequences of their choices and adjust accordingly, enhancing their sense of confidence and reducing uncertainty.
- Personalized Prioritization - In complex systems, each user may encounter different needs and changing goals. When the system can identify preferences and provide content, services, or options that are tailored to the user, it allows them to feel that the system "understands them," making the experience more relevant and focused.
In Conclusion, complex systems are not about "solving problems" but about creating a smart framework that allows both users and the system to learn and grow together. Instead of fearing uncertainty, designing systems should embrace it, leverage it, and use it as a source of innovation. Users are not looking for a "perfect" system – they are looking for a system that can evolve with them, with a deep understanding of their specific needs and contexts.
