Systems Thinking Perspectives on CQI and Public Health
Systems thinking involves taking account of where you stand, what you’re doing, and where the bounds of your influence and influences are. By learning how to think about systems, we are better able to design strategies to ensure that our engagements are producing the most beneficial results for our efforts and when combined with design thinking we gain further opportunities to shape the systems closer to what we aspire them to be.
I recently was invited to speak to the first meeting to advance CQI (Continuous Quality Improvement) in public health in Ontario (Canada) on the topic of systems thinking. The one day workshop was aimed at bringing together members from nearly every public health unit in the province to meet and discuss issues related to quality improvement and public health.
In twenty minutes we did a whirlwind through some of the key features of systems that are relevant to quality improvement by looking at the nature of systems (chaotic, complex and ordered) and steps that can be taken to understand them in terms of setting the appropriate targets, methods and tools for defining and assessing quality within such systems.
By understanding the nature of systems we can avoid the trap of using linear metrics for non-linear problems. Much of the literature on quality improvement has its roots in manufacturing, which are largely linear systems that seek to predict, control and emphasize efficiencies and the elimination of waste. Yet, public health is largely about complexity. In a complex system, what might be considered inefficiencies could be natural byproducts of the system itself and cannot be necessarily avoided. Further, such ‘noise’ could be sources of innovation or weak signals that indicate something significant is to come.
Public health operates in a tricky space because it deals with highly complex problems and systems and linear, straightforward ones simultaneously.
Below is a summary set of slides used to highlight the talk (the original slides were more visual, but those don’t help you out if you hadn’t been in the room).

Building Quality Into Systems Design
One of the central points I made was that systems can be (partly) designed and that developmental design is a process that integral to optimal functioning in a complex system. By paying attention to what is going on and the relationships that form within the system the feedback is set to allow for intentional development of the system itself. This does not assure control, but it allows for positive influence rather than being solely reactive to whatever the system produces. This is necessary if one is to promote quality and ensure quality not just measure it as if it was a static object.
Whether one uses linear, quantitative measures or more non-linear, multi-method approaches to assessing the quality of a public health product or service, the key is knowing what kind of system you are operating in.
My takeaway points were:
