Review Technique (PERT) Strategies for Positive Risks Opportunities Exploit ensure the risk happens Share allocate some or all to 3rd party Enhance increase the probability of an opportunity Accept - willing to take advantage if it comes along Strategies for Negative Risks Threats
Avoid change PM plan to eliminate Transfer shift all or some to 3rd party Mitigate reduce probably and/or impact to within acceptable limits Accept no action; deal with risks as they occur Uncertainty Known Unknowns Contingency Reserve Part of the cost baseline May change as project progresses Risk response is acceptance Mitigation and contingency plans are documented Management Reserve Unforeseen work that is within scope Part of project budget
Requires approved change Added to cost baseline as used Estimating Analogous Cost Estimating May be less accurate than other methods May take less time and cost less to do than other methods Parametric Cost Estimating Increased accuracy possible Depends on data and infrastructure built into process Bottom-up Estimating Estimate each work package For greater accuracy keep breaking it down Three-Point Estimating Consider estimate uncertainty (RISK)
