When a system migration fails, the post-mortem almost always surfaces the same culprit: not the technology, but the categories used to describe what the technology was supposed to do. The medieval Islamic logician al-Farabi argued in his *Ihsa al-Ulum* (Enumeration of the Sciences, c. 952 CE) that the collapse of any organized practice usually begins not with bad execution but with *incoherent classification* — when the names we use to sort things stop mapping onto the actual distinctions that matter. Finance IT sits inside this trap constantly. 'Legacy system,' 'technical debt,' 'integration layer' — these terms feel precise but often function as buckets that hide more than they reveal, obscuring whether a problem is architectural, organizational, or simply a failure of specification upstream. Al-Farabi's corrective was systematic: before proposing any solution, explicitly audit what your categories are *doing* — what they include, what they silently exclude, and whether the boundaries between them reflect reality or just inherited convention. The practical move is small but potent: the next time a requirements document or incident report lands on your desk, spend five minutes asking not 'what does this mean?' but 'what is this category *hiding*?'

What is one category your team uses daily in documentation or reporting that everyone understands differently — and what decision has that hidden ambiguity already shaped?
