Is it better to relationalize or rationalize?

It depends if you’re talking business (truthful business) or personal life:

Rationalize = make (a company, process, or industry) more efficient by reorganizing it in such a way as to dispense with unnecessary personnel and/or equipment.

Relationalize = Building capabilities of an organization through relational databases, systems, and experiences.

As long as this is done truthfully (and not falling into the "Rational-lies" trap), why do you need to have one without the other? They're not mutually exclusive.
