KK: /nɑnˈstrætɪdʒɪk/
Not related to planning or strategy; lacking a clear plan or purpose.
The team's nonstrategic decisions led to confusion and wasted resources.
Nonstrategic → It is formed from "non-" (meaning not) and "strategic" (from Greek "strategikos", meaning relating to a general or army). The word "nonstrategic" means not relating to or not involving strategy.
Think of 'non-' meaning not, and 'strategic' relating to planning or strategy — so nonstrategic means not involving any planning.
