TM1 Fanboy is an independent publication about the history of enterprise decision-making.
It begins with TM1 and follows a larger story through spreadsheets, OLAP, enterprise planning, business intelligence, data culture, artificial intelligence, and decision intelligence.
The technologies change. The promise remains familiar: better information, better plans, and better decisions.
For the Office of the CFO, that history offers a useful perspective. Faster calculations, richer models, and new interfaces expand what finance teams can do, while trust, adoption, accountability, and action remain organizational questions.
The recurring question behind the publication is:
How has technology changed organizational decision-making—and what has remained unchanged?
OLAP lets people explore business data across dimensions such as time, product, region, and scenario. Its history explains why common RFP criteria can conceal very different solutions.
TM1 feeders are not an awkward exception to sparse calculation. They identify rule-derived cells that may matter, preserving correctness without materializing an entire cube.
TM1 was fast decades ago and remains fast because it stores, calculates, and reuses the relevant parts of a planning model instead of materializing the entire cube.
TM1 did not begin at a single moment. Its origins stretch from an Exxon problem context through prototype work, company formation, public announcement, and eventual visibility in the trade press.
