In several discussions and posts I wrote, I talked about systems thinking, assuming everyone has the same understanding.
For example last year with the PLM Global Green Alliance (PGGA) we had a discussion with Frank Popielas Managing Partner and Co-founder of SMS_ThinkTank™ related to sustainability. We used the term “Systems Thinking” several times assuming everyone knows the concept.
I should have known better. When using terms in your profession, you always have to verify if the others have the same meaning. Crucial when you start a PLM implementation project.
For example, several years ago, I was asked to audit a PLM implementation that got stalled because the PDM and ERP-system capabilities created a conflict. In my first interview with the PLM team, they mentioned they were quite advanced in Systems Engineering. Everyone in the core team confirmed this. However, when diving into the details of the “Systems Engineering” activities, it appeared that they were talking about (product) Configuration Management.
When working with different people, always make sure you have a common dictionary.
What is a part? What is a material? What is a Workflow, and is it different from a Business Process? And also, for Configuration Management, you often see two definitions.
One focuses on the consistency of the product’s definition, the other more on the allowed configurations of a product. So now let’s dive into Systems Thinking which is not the same as Systems Engineering.
Systems thinking – a definition
When I checked on Wiki, I found this complex definition:
Systems thinking is a way of making sense of the complexity of the world by looking at it in terms of wholes and relationships rather than by splitting it down into its part. It has been used as a way of exploring and developing effective action in complex contexts. Systems thinking draws on and contributes to systems theory and the system sciences.
A careful reader would extract from this definition that the focus for systems thinking is looking at the bigger picture, the whole, a holistic approach. Of course, when using a holistic approach, you take more relationships or possibilities into account, which broadens your thinking (or value of your solution). The opposite of Systems Thinking is to focus on a single issue or part and describe it best. Let me explain this by an example:
The BIC ballpoint
You might remember the first BIC ballpoints with the sharp cap when you are as old as me.
This image is from the time I was born. The BIC ballpoint, with the pointed cap, was one of the most popular ballpoints during my teenage years.
In primary school not allowed, as we first had to learn to write with an ink pen or fountain pen. The BIC pen at that time was designed as a product with a single purpose: enabling people to write affordable, comfortable, and fast.
With a more holistic view of the BIC pen, you might say: “What happens when children play with it?” And apparently, there were accidents with children stabbing themselves in the eye with the sharp cap.
And this was indeed the case when considering the BIC ballpoint as a system; other stakeholders and scenarios were considered.
Now the cap is flattened (safe for children). The cap’s open end is apparently there to support performing a tracheotomy when no medical equipment is available (just a sharp knife and the BIC ballpoint are needed).
Don’t try this at home for fun: Performing the Tracheotomy
I hope the example illustrates that you can look at a product differently.
First as a product with a single purpose (single stakeholder) or as a system interacting with other stakeholders (writing, safe for children, first aid support).
System Thinking, therefore, is an attitude which not natural for humans. In his famous book Thinking Fast & Slow, Daniel Kahneman explains that our evolutionary brain always wants to save energy.
Therefore our brain is pushing us to make fast intuitive decisions, not always the ones that you would make after serious thinking.
Systems Thinking costs energy for the brain.
Often we hear that companies want to reduce their costs and time spent on engineering – more efficiency.
Systems Thinking and Systems Engineering are aiming for the opposite – spend more time thinking and analyzing in the virtual world, before committing to the physical world. Fixing issues once you are in the physical world is much more costly than in the virtual world.

This brings us to the relationship with Systems Engineering
Systems thinking and Systems Engineering
You could say Systems Engineering is the best example of Systems Thinking. There are various viewpoints on Systems Engineering, best characterized in these two directions (Wiki here):
- Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful function. Here the focus is on managing in a proven manner complexity
- Systems engineering focuses on analyzing and eliciting customer needs and required functionality early in the development cycle, documenting requirements, then proceeding with design synthesis and system validation while considering the complete problem, the system lifecycle. This includes fully understanding all of the stakeholders involved. Here the focus is on delivering the best product for the relevant stakeholders involved, not necessarily managing the complexity of the product.
To manage complexity, we have always used models. The weather forecast is based on models, the profitability of a business is based on models, and the behavior of a product can be predicted and analyzed using models. This is Model-Based Systems Engineering MBSE), and I wrote a lot about the Model-Based approach last year. Read The road to model-based and connected PLM
When it comes to extending the support for different stakeholders, we have seen the example of the BIC ballpoint.
However, when we start to talk about sustainability, we will see that by enlarging the number of stakeholders and their importance, we observe another way of Systems Thinking.
Systems thinking and sustainability
The title of this post is related to the challenges we have with sustainability, our society and even our planet. Currently, reducing carbon emissions gets the highest priority as we see the impact on our planet. Perhaps the awareness is not the same for everyone; the richer you are, the less you might feel impacted by climate change. Still, indisputably it is happening as the IPCC is reporting.
Now let’s look at the relation between systems thinking and sustainability.
Let’s imagine I work for a tier 2 or tier 3 supplier of an OEM. This means the OEM wants a component for their solution with the highest quality and the lowest price.
In the traditional approach, the supplier will try to find the cheapest materials that match the required quality. They will look for the most inexpensive manufacturing process to build their component. Everything extra will reduce their chances of remaining the OEM contractor and profitable. The only stakeholder in this process is the OEM and potentially some existing regulations. For example, ROHS controls the usage of hazardous materials.
Next, imagine a supplier that wants to be more sustainable. They will add sustainability requirements to their component design. They start to treat their product as a system. What would be the difference between choosing material A over material B or choosing production process ABC over production Process XYZ?
If it is up to the OEM, it is only costs, quality and compliance. Suppose the supplier will select an alternative material that has less impact on the environment. For example, recycling or needing less energy (carbon emissions) is easier to produce. In that case, this option might be more expensive. It is up to the OEM to decide if they accept this higher cost price to be more sustainable with their products.
To understand the sustainability of a product, we need to dive into a full Life Cycle Assessment (LCA). LCA is at the heart of PLM.
When a product or component is designed, the LCA will give you the information related to the impact of your product, assuming you have the accurate data to make the assessment. This is currently one of the major areas to focus on when it comes to sustainability – how can we measure the environmental impact of each part through its whole lifecycle.
With sustainability, the needs are no longer defined by the OEM. Other stakeholders, like authorities and consumers, will also have an impact. Realistically, we will see that mainly regulations will be the biggest driver towards sustainability as consumers still want the lowest price.
Currently, we see this behavior with the rising energy prices. Unfortunately, people complain about the price instead of realizing the price has always been too low. Changing behavior (energy consumption) might be the best path for the future, but that is more difficult than complaining.
Systems Thinking and the Circular Economy
Finally, I want to mention one topic closely related to Systems Thinking and Sustainability: the Circular Economy. The Circular Economy is well explained by the Ellen McArthur Foundation. Follow the link and get educated as the Circular Economy is about a system. A system that tries to minimize the leakage of resources and the need for new raw materials. Each loop is a process to consider.
With the PLM Global Green Alliance, we discussed the circular economy together with Darren West from SAP in our session: PLM and Sustainability: talking with SAP. I hope and trust we will learn more about companies to follow the principle of a circular economy.
Want to learn more?
There is so much more to say about Systems Thinking in general, and I will come back to this topic in a future post. Meanwhile, I recommend this post for all of you who want to learn more about systems thinking and sustainability: Systems Thinking can help build a sustainable world: A Beginning Conversation from the MAHB (Millennium Alliance for Humanity and the Biosphere). There is so much to learn and discuss if you are actively looking for it.
Systems Thinking is needed to solve the issues in a complex society. It is an attitude, not a new approach. Systems Thinking helps to manage a complex system, it helps to address sustainability, and it helps fight against populism. Simple answers do not exist – looking to the bigger picture, using systems thinking will make you better informed wherever you are on this limited planet
