Many years ago, Melvin Conway observed that the way organisations are structured impacts any system they create. In his article How Do Committees Invent (Conway, 1968), he wrote:
Any organization that designs a system (defined more broadly here than just information systems) will inevitably produce a design whose structure is a copy of the organization’s communication structure.Melvin Conway
At the time, the Harvard Business Review rejected his original paper because he hadn’t proved his hypothesis. The law became well-known after Fred Brooks cited the article and the idea in his classic book “The Mythical Man-Month,” calling it “Conway’s Law” (Brooks, 1995). The name stuck and spread, particularly among software developers.
Despite the author’s remark (to apply this not just to information systems), a lot of research that has validated this principle came from software developers (Bevan, 1999), including—a study by Microsoft (Nagappan et al., 2008). In many ways, the law is often referred to by stating that software is the product of the developing organisation communication structure.
This has led many organisations to experiment with more distributed teams agile methodologies. But at the same time, there is still a consideration that a group of disconnected programmers could infuse their work with their individual biases (Watts, 2020).
The reality is that this statement has a much broader validity. In all my work in organisation design and beyond, the feeling that this law holds is a constant.
Scholars often refer to the law by two related concepts:
For the moment, it is sufficient to say that multiple researchers have validated these principles in various fields, not just in software design.
The reason is that if we move away from one second from software products into something broader, we can immediately see many relationships with concrete cases out there:
This is becoming more and more relevant today because the acceleration aspect of VUCA makes all these aspects more visible.
Having had several experiences in retail, I see the actual effects of Conway’s Law whenever I enter a store. Physical stores (and, notably, e-commerce sites) deeply reflect how the organisation is structured and its communication structure. Think of apparel: few cases come immediately to mind.
All these examples reflect how broad the implications of Conway’s Law are, especially if we intend the concept of “system” in its most enormous possible sense, precisely as Conway himself intended.
This is why we should look at the critical output that an organisation produces, the experience delivered to its customers. This makes me think we can extend Conway’s Law with a corollary.
The quality of customer experience delivered by an organisation will inevitably be the product of its organisational design.
And I intend all elements of organisational design. Communication structure is one (and probably the most relevant), but what emerges here is another layer of meaning for the concept of intentionality in organisation design: you want to provide consistency across all your organisational elements.
There are cases of organisations that have reviewed their design with this principle in mind (Gilson, 2021). But we need to be careful here. The idea to go by a shortcut by applying what is called Inverse Conway Maneuver solely to a part of your organisation framework can be equally dangerous if not done strategically (Durand, 2021). The example is for those organisations that started distributing teams in an area to discover how many political issues arose, with individual groups still guided by old-framed values of power linked to size (Woods, 2017).
A few years ago, in his book How Google Works, Eric Schmidt (Schmidt, 2014) casually referred to the outputs of Conway’s Law.
You should never be able to reverse engineer a company’s organizational chart from the design of its product.Eric Schmidt, How Google Works.
I found d this quote to be illuminating back when I read it, exactly because of the load of consequences that Conway’s law brings with it. How often by buying a product, or experimenting a service, you are clearly able to see the defects of the organisation that produced it?
The above strikes a new chord for the Intentional Approach to Design that I am exploring and should include the following steps.
When I originally posted this article as part of my newsletter, I received quite a lot of feedback. Antonio di Stefano referred to the concept of Lemniscate, an algebraic figure where all the points of the curve have a consistent relationship with their focus. The resulting figure is akin to the symbol of infinite we often use.
Why is this relevant? Essentially what this figure represents is that for any internal point there is an external representation of it. And vice-versa. So, for any intentional decision, we do on the design, there is an unintentional consequence externally, at the same time for any external situation that affects our organisation, there is an unintentional consequence internally.
The way we design (or chose not to design) the way we organise ourselves, generates images of us in all successive projections or systems. And everything that impacts from outside influences our design
This really makes Intentional Design an endless pursuit of consistency between intentional design action and external system of reference. With Conway’s Law being somewhat the engine of propagation, so deeply linked with consistency.
Have you seen ConWhy way’s Law in action? What are your thoughts about it? Is it something we should exploit instead of battling?
