In the summer heat, when The BFD alone isn't quite quenching your thirst for forecasting know-how, here are several other sources:
CatchBlog -- by Steve Morlidge of CatchBull
From his 2010 book Future Ready (co-authored with Steve Player), to his recent 4-part series in Foresight dealing with the "avoidability" of forecast error, Steve is delivering cutting edge content in the area of forecast performance management. He also contributed a Foresight/SAS Webinar available for on-demand review.
The Forecast Pro -- Eric Stellwagen of Business Forecast Systems
Eric delivers great practical tutorials on various forecasting topics through his blog, and also in conference presentations and articles (including 2 chapters in the Foresight Forecasting Methods Tutorials compilation).
IBF Blog -- various industry contributors
Good source for previews to upcoming Institute of Business Forecasting events, contributed by conference speakers. Also event recaps by conference attendees, and previews of the Journal of Business Forecasting.
SCM Focus Blogs -- by Shaun Snapp of SCM Focus
Shaun is a prolific writer of blogs (he maintains several on his website) and books (most recently Rethinking Enterprise Software Risk), and provides a sharp critical eye on IT, ERP, supply chain, and forecasting issues.
Supply Chain Shaman -- by Lora Cecere of Supply Chain Insights
Lora is a long time industry analyst and, like Shaun, is another prolific writer covering a wide range of topics. Her recent ebook The Supply Chain Shaman's Journal: A Focused Look at Demand includes some nice mention of FVA.
