3 What Is Risk and Risk Management? Risk: »Definition: Risk is an event that threatens the accomplishment of one or more future goals or objectives »A Risk is described by the likelihood that an event will occur and the severity of the consequence of that event should it occur. »Risk is about a possible future event and is often confused with issues and problems. If the likelihood is certain or near certain, then it is not a risk. Risk Management: »Definition: Risk management is the formal process of identifying risks, assessing their magnitude, making decisions about how to handle, and then tracking the progress of the handling approach.

5 How to State a Risk – Formula for Success A risk statement is written as follows: »If A occurs because of B, then C will be the result. A is symptomatic, B is causal, C is the outcome Common errors: »Thinking that problems and issues are risks »Using the Risk Management Database as a tool to bring attention to problems and issues
6 Exercise 1a Identify whether the following contains a risk or a problem: You have an 16 year old son who has a job at a restaurant in Baybrook Mall. He wants to drive your car to work. … a shady part of town. He works the night shift. Plus: Hes moved into an apartment with another young man who has already had his drivers license revoked

9 Exercise 3a Were back to your son…what would you do with the risk of him having an accident for which he is at fault? He is currently uninsured. How would you Avoid this risk? … Transfer : He has a good driving record, lives at home What if your son is in a hi-risk pool and collision insurance is $4500 per year? Can you think of some Mitigation actions?
10 Outline What Is Risk Analysis? What Products Do We Need To Produce? How Are They Produced?
11 What is it?: Definition Risk Assessment (about a risk) »The process of estimating the probability and impact for each risk »Assigning other relevant attributes to a risk Risk Analysis (about all risks) »Combining and studying the effects of multiple risk assessments »A "snapshot" in time of the projects risk environment »Often done with a Monte Carlo simulation »Uses models to understand characteristics of the project »Results derived include Probability of meeting the project objective such as a completion date Contingency needed to achieve an acceptable level of likely project results Finding the risks which put the objective in greatest jeopardy Source: PMI RiskSIG Lexicon: www.risksig.com/resource/lexicon.htm
12 Assessment – Assigning A Value To A Risk From previous Module, we have learned how to construct the Risk Matrix using qualitative techniques M L VL H M L VH H M VH= Very High H= High M= Medium L= Low VL= Very Low 3 X 3 Space Station & Genesis 4 X 4s are common, e.g. JPL/MER Does not have to be symmetrical 5 X 5 not a requirement
13 Risk n After Assessment what do you have? Ordered sets of individual risks But, no clear understanding of the integrated risk environment Risk 1 Item Description REDYellowGreen Affinity Grouping Consolidation Classification Evaluation Top – 10 (or so) --- Risk n Risk 1 Item Description
14 Now what should I do with this stuff? Decision-making with piles of risks? How? These decisions need to be made based on the total integrated risk impact to the project – That integrated impact is often counter-intuitive The easy way out is to reduce all RED risks and most YELLOW risks, but can you afford it? If, so, then stop here! The easy way out is to reduce all RED risks and most YELLOW risks, but can you afford it? If, so, then stop here!

30 Format of Class Exercise A simplified space project will be presented An @Risk/MS Project simulation of the project will be presented The model will be run to assess the impact of the risks The students will be presented with the risks as identified by the simulated project, question? Is the risk list complete? The students must select a mitigation plan from several options presented The case will be rerun with the selected mitigation plan A random number generator will be used to obtain final outcome The Genesis Model will be shown using a more complex simulation tool in order to demonstrate other capabilities

42 QUALITY ASSURANCE AND THE SINKING OF THE LARGEST OFFSHORE OIL PLATFORM March 2001
43 For those of you who may be involved in project cost control (at whatever level),
44 please read this quote from a Petrobras executive,
45 extolling the benefits of cutting quality assurance and inspection costs,
46 on the project that sunk into the Atlantic Ocean off the coast of Brazil in March 2001.
47 "Petrobras has established new global benchmarks for the generation of exceptional shareholder wealth
48 through an aggressive and innovative programme of cost cutting on its P36 production facility.
49 Conventional constraints have been successfully challenged
50 and replaced with new paradigms appropriate to the globalised corporate market place.
51 Through an integrated network of facilitated workshops,
52 the project successfully rejected the established constricting and negative influences of prescriptive engineering,
53 onerous quality requirements, and outdated concepts of inspection and client control.
54 Elimination of these unnecessary straitjackets has empowered the project's suppliers and contractors to propose highly economical solutions,
55 with the win-win bonus of enhanced profitability margins for themselves.
56 The P36 platform shows the shape of things to come
57 in unregulated global market economy of the 21st Century.
58 And now you have seen the final result of this proud achievement by Petrobras.
59 QUIZ: 1.How many lives were lost to this cost saving effort and how did this impact the environment, needlessly? 2.Did the person giving this speech or anyone in upper management connected with this decision lose their job/bonus? 3.How much did Petrobras really save? 4.Does your company have a cost saving effort? If so, youd better know how to swim.
