How Does Experience with Delay Shape Managers’ Making-Do Decision: Random Forest Approach Open
Making-do, a decision to start a construction task despite knowing that its preconditions are not fully ready, is a complex dilemma for construction managers. Managers' previous making-do decisions and the resulting consequence, delay, can…
