Project crashing during time-cost optimization is executed by____________?
Show answer Hide answer
Answer: D. on original critical activities and those that become critical at any stage of crashing in the order of ascending cost slope
Explanation
Crashing proceeds by targeting original critical activities and newly critical paths sequentially. Cost slopes dictate the order of crashing to ensure minimal financial investment for time saved. Newly formed critical paths must be crashed simultaneously alongside original critical path tasks. Project crashing is the process of shortening schedule duration by adding extra resources. Cost slope represents the additional financial cost incurred per unit of time saved. Time-cost optimization balances direct crashing costs against indirect overhead savings.
Construction managers crash schedules when contractual completion deadlines impose heavy financial penalties. Project owners evaluate crashing options to accelerate facility revenue generation capabilities. Engineers analyze cost slopes to determine the most economical activities for schedule compression. Option A is incorrect because crashing all project activities causes unnecessary financial expenditure. Option B fails to account for parallel paths becoming critical during the crashing process. Option C ignores new critical paths that emerge as initial critical tasks are shortened.
