Just to add some details to the above well-informed comment: Sometimes people who are not used to management of large-scale projects are surprised by the development of tools and specialized vocabulary in project cost/schedule/risk assessment. The following is a pretty good summary of some common tools that integrate cost, schedule, and risk analysis: http://www.iceaaonline.com/ready/wp-content/uploads/2015/06/INT-04-Integrated-Cost-Schedule-Risk-Analysis.pdf http://www.iceaaonline.com/ready/wp-content/uploads/2015/06/... See in particular the first couple of slides on motivation, the "risk cube" on pages 19-20, the scatter plots of cost/schedule on pages ~30, and the example "risk lists" on page 57. Project management can be viewed as an assault on the remaining top items of the relevant risk list. All these concepts are standard practice for large aerospace projects. There will be risk analysts with stats or operations research PhDs running simulations and developing tailored methods just to assess risk of large projects.
