In a previous job I had set up a notebook to analyze some of the models our team produced - it was essentially a Q/A notebook that generated data from our models, algorithmically looked for unphysicalities in our models, and plotted any it found.

The rest of my team used it for the models they were working on. The alternative/old way was just too painful (lots of manual steps).

But although reuse by others is a touted feature, it's not really that important. It's incredibly useful for one's own workflow. Think of the convoluted Excel sheets people often have at engineering companies. They get new data, copy and paste it into Excel, and get new plots. This is no different.

Can't imagine trying to pump my data into someone elses pipeline and crossing my fingers for results!
