DISTRIBUTING BUSINESS RULES FOR BUSINESS CONCURRENCE
Step 13 requires that business rules be distributed to all business par-
ties that are stakeholders in the rules. The business rule administrator rec-
ognizes that the 13 business rules represent one point of view: that of the
nanny agency owner.
In searching for appropriate reviewers and for additional sources of
business miles, the business rule administrator makes use of the prelimi-
nary enterprise function model. From here, with Mary's assistance, the
administrator identifies other people who perform some of these functions
and who are stakeholders in the rules.
With Mary's help, the business rule administrator identifies customers
and nannies to contact. The business rule administrator also knows that
Mary is likely to provide the names of satisfied customers and nannies, so
even this view is not totally without bias. Subsequently, the business rule
administrator discovers another player in the business. Mary has part-
time help from her neighbor when business is busy. As an aside, it is often
very insightful to correct business rules about an enterprise from sources
outside the enterprise.
RESOLVING CONFLICTS
Step 14 resolves conflicts. The business rule administrator quickly dis-
covers one area of discrepancy over the definition of a caregiver. The
nanny states that a caregiver need not ever provide housekeeping services
and so the rule should be reworked as A CAREGIVER IS A PERSON WHOSE
LIVELIHOOD IS TO PROVIDE DEPENDENT CARE OR LIGHT HOUSEKEEPING
SERVICES FOR A FAMILY IN THE FAMILY'S HOME.
When Mary is presented with the proposed update to the business rules,
she insists that all of her caregivers will provide some housekeeping —
what is open to negotiation is the term light housekeeping. After all, she
places only high-quality, dependable nannies who are very amenable to
provide housekeeping services to the family.
The neighbor concurs with the nanny, stating that she herself has placed
nannies who she is certain will not perform any housekeeping duties.
Again, the business rule administrator faces a dilemma and must reevalu-
ate the scope of business rules. Are the business rules to reflect those of
ownership, support staff, customers, and products (e.g., nannies)? Are
they to reflect the business as it currently actually operates, as it should
operate, or as it will operate?
The business rule administrator discusses these matters with Mary.
Because Mary is the CEO of the enterprise, she is the ultimate business
authority and business custodian of the data. This is not so easily decided in
