Chain Reaction Ep. 22: How Science Powers Peak Season Operations

Johannes Kloess, Head of Operations at Thortful, brings an unusual background to logistics: microbiological training. That background shapes how he approaches peak season operations. Science teaches you to respect variables, design controlled experiments, test hypotheses. Most peak season operations run on guesswork dressed up as planning. You predict volume will be 40% higher, you hire casual labour, you hope the network holds. Johannes approaches it differently. Model the system. Identify constraints. Test assumptions before committing resources. Run scenarios. The discipline of scientific thinking applied to operations means you're making falsifiable predictions rather than wishful ones. When reality diverges from your model, you learn why. Thortful hits hard during peak season - greeting cards are concentrated in a few periods. Running that without rigorous operational discipline would collapse. Johannes's conversation covers what he's learned about managing volatile demand, scaling quickly without losing control, and building operations that can flex under stress. For supply chain leaders managing peak season logistics, whether in greeting cards, e-commerce, or seasonal goods, Johannes's perspective on applying systematic thinking to operational complexity is immediately valuable. The conversation is less about specific tactics and more about the discipline of thinking clearly under pressure.
