SOME NOTABLE CLIENTS
How can risk analysis translate into ROI?
■ Averages vs. Range Estimates
■ Challenges and opportunities that risk analysis and simulation address?
■ How to make better decisions with risk information
BEWARE OF Averages
AVERAGES Conceal Risk
Range estimates address hidden risk
-20 345 47 335
Single-Point Estimate
More information, Better decisions
142.5K
Ranges show the full spectrum of possibilities
116.25K
Range informationProbability of occurrence
Or this one?Would you pick this project?
Only ranges can describe risk
■ Definition: Ranges define a range of potential occurrences and are necessary to obtain and communicate more meaningful and relevant information.
■ Where to start? Range Estimates…
▪ Can and should be derived from historical data
▪ Can be known statistical distributions
▪ Can be estimated by experts using 2 or 3 points (Min, Max and
Most-Likely)
Simulation models for better decisions require ranges as inputs
Analytics to improve project process performance
■ More than 50% of projects fail to meet EXPECTATIONS!
■ Why are so many projects challenged?
■ The cost of challenged projects
■ How can we break the 50% barrier?
■ Other barrier crashing opportunities
More than 50% of projects fail to meet EXPECTATIONS!
Simulation and Optimization WILL improve project success
Recent Trends from the Chaos Report …
“Initial cost and schedule estimates for major projects have invariably been over-optimistic. The risk that cost and schedule constraints will not be met and cannot bedetermined if cost and schedule estimates are given in terms of single points ratherthan distributions.” – Final Report of the USAF Academy Risk Analysis Study Team, August 1971
Trend State
Successful: The project is completed on time and on budget, with all features and functions originally specified.
Challenged: The project is completed and operational, but overbudget, late, and with fewer features and functions than initially specified.
Failed: The project is canceled before completion, or never implemented.
Without taking into account risks and probabilities, it is impossible to :
■ Identify truly Critical Tasks and Resources
■ Set appropriate funding and budget levels from the beginning
■ Understand the factors that drive potential delivery dates to better manage risk
Why are so many projects challenged?
Plan for budget AND schedule risk using simulation
■ Costly rework
■ Slow down project execution
■ Makes managing scope creep very difficult
■ Higher project failure rates
■ Diminished returns and benefits
■ Negative impact on the project team’s credibility
the cost of challenged projects
Addressing risk saves money and builds credibility

■ Enhancing the modeling process with simulation and optimization
■ Case and Example Simulation
■ Quantify the effects of variation in your current “as-is” scenario
■ Predict a scenario’s probability of occurrence
■ Identify critical input variables that drive uncertainty or variability in your project plan
■ Determine an optimum and robust solution for your new “to-be” planning scenarios
