+But before incorporating any new practice, first, we can evaluate the processes we are following. A process-centred approach helps us to remove the focus on human error and be aware that processes can fail people with good intentions, and we can enter a cycle of continuous improvement.
+
+> "By defining the process, we can begin to borrow from the rich field of operations,
+which focuses primarily on (the) process. One paradigm that proves especially useful is
+the concept of human error. The seminal book 
+_The Field Guide to Understanding Human Error_ 
+argues for a paradigm shift from the “Old World View” (that
+when an error occurs it is an individual actor’s fault) to the “New World View”
+(that when an error occurs, it is a symptom of a flawed system that failed that
+individual actor) (Dekker 2014). When an error in an analysis occurs, it is safe
+to assume (aside from nefarious actors) that the analyst did not want that error
+to occur. Given that she thought she was producing an analysis free from errors,
+you must look at the way she developed the analysis to understand where the
+error occurred, and create safeguards so that the error does not occur again." ([Parker, 2017a](https://sachsmc.github.io/rpackage-workshop/opinionated-analysis-dev.pdf) and [Parker, 2017b](https://posit.co/resources/videos/opinionated-analysis-development/))

+Repetitive events (like outbreak response and research data analysis projects) give us the opportunity to:

+- Focus on the **process** we have followed,
+- Evaluate **where** bottlenecks occur, and then
+- **Adopt** new practices to be better protected against errors in the next iteration.

+### Deming Cycle
+
+This approach aims to follow a [Deming cycle](https://www.lean.org/lexicon-terms/pdca/) of Plan, Do, Check, and Act, as a foundation for continuous improvement.

+::::::::::::::::: discussion
+
+Exercise: Your experience analyzing outbreak data (the latest... or the most chaotic!)
+
+Take 5 minutes.
+
+Reflect on these questions:
+
+- How do you organize your files and folders?
+- Where does it describe what your project did or how to use it? Was it all in one place?
+- Could your project be reused by colleagues? Do you think it is?
+
+Share one idea from your neighbour.
