Abstract: In this paper, we utilise deductive analytics based on a review of the literature as well as stochastic simulation, and scenarios to perform a comparison between predictive methods like waterfall and adaptive methods such as scrum. We compare these methods using several project management performance criteria such as cost, duration, value delivered, payback (breakeven) period, predictability, project size, criticality, complexity, challenges, etc. Based on these findings, we synthesise a new plan-driven, predictive procedure that will enable it to be competitive with the adaptive/agile methods in situations where it makes sense to use a predictive method.

Keywords: agile method; agile project management; adaptive method; predictive procedure; waterfall method; scrum; breakeven point; traditional project management; hybrid methodology; plan-driven method; iterative development; continuous delivery; disciplined agile; payback period.
