In CSI/CDT programming and early project decision-making, the classic four primary project considerations are:

Function – What the facility must do; the operational and performance requirements.

Form – The physical configuration and appearance: size, shape, spatial relationships, and aesthetic character.

Economy – The financial aspects: project budget, life-cycle cost, operating costs, and economic constraints.

Time – Project and site timing: required completion date, phasing, and schedule constraints.

These four are used in programming and early planning (including site selection and site programming) to structure owner–designer discussions and decisions. During site selection programming, the owner and design team evaluate how different sites support the project’s required function, allow appropriate form, meet economic constraints, and fit within time (schedule and phasing) limitations.

This four-part framework—Function, Form, Economy, Time—matches Option B exactly.

Why the other options are incorrect:

All three incorrect options are variations that re-label or partially capture the same ideas but do not use the standard terminology as defined in CSI/CDT references:

A. Use, space, funds, date

“Use” ≈ function

“Space” ≈ form

“Funds” ≈ economy

“Date” ≈ timeWhile conceptually similar, CSI’s established terminology for programming and site selection is Function, Form, Economy, Time, not this wording.

C. Purpose, shape, cost, scheduleAgain, these loosely correspond to function, form, economy, and time, but CSI uses the more formal terms that appear in its programming discussions and CDT content: Function, Form, Economy, Time.

D. Goal, condition, budget, calendarThese terms are more generic and do not match the recognized four-part framework used in CDI/CDT materials for programming and site selection.
