The process of converting something into a formula or systematic form; the act of formulating or reducing to formulae (British spelling).
From formularise (British spelling, form + -ularise) + -ation (Latin -atio, indicating action or process). The British -ise spelling differs from American -ize.
Formularisation (British) versus formularization (American) shows English spelling's Atlantic divide—same action, different suffixes based on which side of the ocean standardized first, and each group now defends its version as obviously correct.
