SBVR14 — Definition of Business Rule – Being Practicable

A very fundamental idea about business rules is that they are practicable. The current SBVR entry for “business rule” (p.98), however, makes no mention of it:

rule that is under business jurisdiction

Yet, the counterpart of “business rule”, the entry for “advice” (p.99), does:

element of guidance that is practicable and that is a claim of permission or of possibility

If one is extremely observant and patient, one can work out that a business rule does have to be practicable. Here’s how:

• The entry for “business policy” (p.100) has a Necessity that says “No business policy is a business rule”. (*Typo: Needs a period.*)

• The definition of “business policy” (p.100) states that a business policy is an “element of governance that is not directly enforceable”.

--> Putting the meaning of those two expressions together means that business rules have to be directly enforceable ... because they're not business policies.

• The previous entry (p. 100) has a Necessity that says “Each element of governance that is directly enforceable is practicable.”.

--> Since business rules are directly enforceable they therefore have to be practicable.

Who would get that though?!
Resolution:

rule that is under business jurisdiction

rule that is practicable and that is under business jurisdiction
