You can find definitions and discussion of all terms in blue on Business Rule Community: http://www.brcommunity.com/BBSGlossary.pdf
rulebook: the collection of elements of guidance for a business capability, along with the terms, definitions, and wordings that support them
Discussion: The rulebook of a game enumerates all the do’s and don’ts (rules) of that game along with the terms and definitions (vocabulary) needed to understand the rules. Each participant in the game, whether player, coach, referee or umpire, scout, spectator, or media person, is presumed to understand and adhere to the rules to the extent his or her role in the activity requires. The rulebook sometimes suggests how to play the game to maximum advantage, but never dictates playing strategy.
Similarly, a rulebook in business includes the business rules (and advices) needed to perform day-to-day operational business activity correctly or optimally, along with the structured business vocabulary (fact model) needed to understand the business rules correctly. Each participant in the business activity must adhere to the business rules to the extent his or her role requires. The rulebook never dictates business strategy, but should reflect, enforce, and measure it.
Unlike the rules for a game, however, business rules change, often quite rapidly. Therefore knowing the original source of each business rule, its know-why, and its full history of modifications, as well as how and where the business rule is currently deployed, is essential in effective rulebook management.
rulebook management: the skills, techniques and processes needed to express, analyze, trace, retain, and manage the business rules needed for day-to-day business activity
general rulebook system (GRBS): an automated, specialized, business-level platform for rulebook management
Discussion: Key features of a general rulebook system (GRBS) include rich, interactive support for structured business vocabularies (fact models) and comprehensive traceability for business rules (not software requirements).
Unlike a business rule engine (BRE) a GRBS is not run-time. Think of a GRBS as more or less like a general ledger system, except for Business Analysts. Because of the potential of GRBS to support compliance and accountability, a GRBS is indispensable for improved business governance.
