OMG released version 1.3 of SBVR (Semantics of Business Vocabulary and Business Rules) last month – comprehensively reorganized for approachability, but not changed. Some thoughts …
Ever hear the conversation that three baseball umpires once had? If you don’t live in a baseball country, it’s an archetypical story, so you’ve probably heard some variant. By the way, in American English a ‘pitch’ is a throw of the ball for the batter to try to hit, not the field of play. Meanings matter!
- The first umpire says, “Some pitches are balls and some are strikes. I call them as they are.”
- The second umpire says, “Some pitches are balls and some are strikes. I call them as I see them.”
- The third umpire says, “Some pitches are balls and some are strikes. But they aren’t nothing till I call them.”
Most modeling techniques primarily focus on modeling the real world as it ‘really is’. They essentially take a first-umpire
point of view or maybe second-umpire
. I come from that tradition too. My 1987 book Entity Modeling
was about doing that … modeling the real world as it ‘really is’. Pretty much all professionals with some IT background come from that world.
Working with business people and business rules for the last 25 years, however, has taught me that business is really more of a third-umpire
world. Think of laws, regulations, statutes, contracts, agreements, terms & conditions, policies, deals, bids, deeds of sale, warranties, prospectuses, citations, complaints, receipts, notices … and business policies.
Even businesses that deal with tangible stuff (e.g., railroads, electrical transmission, infectious diseases, etc.) live in a third-umpire world. And many of the most automated organizations around have no tangible product at all (e.g., finance, insurance, government, etc.). They really exist only
in a world of words (between people).
It’s humbling to realize that the way the business world ‘really is’ is more directly the product of words exchanged by the players in a conversation game than anything IT professionals can model directly. But why would it be otherwise? Do IT professionals really know better than business owners, business managers, lawyers, engineers, subject matter experts, etc.? Really?!
SBVR, in contrast to almost all other standards, doesn’t try to model the way the real world ‘really is’. Instead, its focus is on modeling what is said
about the way the world really is. It’s fundamentally a third-umpire standard
. You simply have to understand what the words mean – and that’s a human-communication issue.
Yes, the SBVR world view is
a game changer. It also happens to align closer with some of the most exciting new work in computerization today including cognitive computing and machine learning.
I stand accused by peers in the standardization community of wanting to go beyond the ‘capture, exchange and production of information’. Sure, I can live with that.
