Organizations vary in their appreciation of the potential impact of the risks that could affect their achieving time and cost goals while completing the project’s scope.  This presentation lays out a schedule risk analysis maturity model that allows organizations to determine: (1) where they are today on the scale from “not aware” to “advanced integrated cost-schedule risk analysis” and (2) where they want to be, what is their optimal level of risk analysis maturity.  The levels of maturity are described: 

  1. Unaware of cost or schedule risk – rely exclusively on the deterministic finish date and cost estimate, uninterested in talking about risk. 
  1. Basic risk awareness – understand that risk to cost and schedule exist but unaware that there are risk analysis methods to help. They say: “Why do I care?  This is the way we have always managed risk on my projects?” 
  1. Qualitative risk analysis – a traditional way to identify individual risks, their probabilities, impacts and potential mitigations. Yields the risk register, identifies which risks are red, yellow or green. Cannot estimate the likelihood of finishing on time and on budget or the amount of contingency needed. 
  1. Basic quantitative risk analysis – using the cost estimate and schedule as mathematical models of the project.  Places ranges (minimum, most likely, maximum) directly on the activities and cost line items.  These ranges are supposed to be images of the effect of risks that may occur on individual activities or costs but they are individuals’ assessment without the benefit of using the project schedule to translate the uncertainty into finish-line consequences.   Does not permit quantitative analysis of the risks themselves to drive the Monte Carlo simulation (MCS) of the model, and, in particular, ignores the importance of some risks that affect multiple activities, thus misses the prioritization of the risks. Focuses on the activities’ likelihood of being critical, not the risks that jeopardize the finish date. 
  1. Modern cost or schedule risk analysis –uses the identified risks to drive the Monte Carlo Simulation.  Specific risks can affect many activities and activities’ variability may be influenced by multiple risks.  Prioritizing risks’ effect on the project objectives can be measured by iterative simulations, eliminating each risk in turn (with replacement) so the risks, not the activities or cost line items, can be prioritized by the number of days saved if the risk is fully mitigated.   Correlation is modeled during MCS, not guessed-at in a workshop.  Achieving time and cost targets independently is shown by the cumulative distribution results. 
  1. Advanced integrated cost and schedule risk analysis – recognizes that the impact of schedule uncertainty affects time-dependent resources’ cost. Uses resource-loaded CPM schedules. Cost is placed on the schedule using time-dependent (labor) and time-independent (materials) so the simulation calculates consistent finish dates and costs in each MCS iteration.  The Joint Confidence Level (JCL) analysis indicates the probability of finishing on both cost and time. 

This presentation does not drive organizations to achieve full cost-schedule integration (level 5) unless that is desired. Often some projects will require more or less risk analysis maturity depending on size, complexity, type of project or other criteria.
