ajapõhise

Ajapõhise is the Estonian adjective ajapõhine meaning time-based or time-dependent. It describes things whose basis, scheduling, or evaluation is determined by time rather than by other factors such as cost or resources. The term is used across various fields to indicate that timing, chronology, or duration is the key factor in a process, plan, or system.

Etymology and grammar: ajapõhine is formed from aeg meaning time and põhine meaning based. The word is declined like other Estonian adjectives. The base form is ajapõhine; in sentence structures it appears in different cases, for example ajapõhise lahenduse (genitive singular), ajapõhise süsteemi (genitive singular), or ajapõhised meetodid (nominative plural). The genitive plural is ajapõhiste lahenduste, and the partitive forms follow standard declension patterns for adjectives ending in -ine.

Usage: Ajapõhise is commonly found in project management, software development, planning, and analysis to mark that timing or scheduling is the primary basis for decisions or evaluation. It can describe approaches, methods, systems, and plans, e.g., ajapõhine lähenemine (time-based approach), ajapõhise süsteemi toimimine (functioning of a time-based system), or ajapõhiste meetodite hindamine (evaluation of time-based methods). It is often contrasted with other bases, such as cost-based or resource-based, to emphasize different prioritizations.

See also: related words derived from aeg (time) and põhine (based) are commonly used in Estonian technical and administrative language. In usage, ajapõhine remains a descriptive qualifier rather than a technical term with a fixed definition.
