Drawing on the expertise of J+D Forecasting, this article examines forecast model design: how to build a model that supports decision-making across the full planning cycle, and the design failures that undermine even technically capable forecasting functions.
The article covers:
- Why models built for analysts erode trust and get abandoned
- How to balance model complexity against usability
- What scenario functionality requires, and where communication breaks down
- How to build version control teams actually sustain
- How to tell whether it’s a model or process problem
Also included: an expert Q&A with Abigail Spedding, Implementation Director at J+D Forecasting, on design horizons, the audit diagnostic, and the organizational habits that most often sit behind a forecasting function that has stopped working.
