Risk Management Production Process
Lecture content • Recap on last week • What is risk management? • Quantitative risk evaluation • Decision trees • Expected Value • Sensitivity analysis • Failure Mode Effect Analysis
What is ‘risk management’? • “A risk is any event that could prevent the project realising the expectations of stakeholders as stated in the agreed project brief or agreed definition” (Young 1996. P71)
Types of risk • Project & Process risks • Estimation errors • Planning assumptions • eventualities • Project manager’s job • Identify & evaluate risk • Get agreement on plans to minimise risk • Take action & monitor results • Quickly fix issues arising from risks
Why is it necessary? • The plan is your route to success • Try to anticipate changes to plan & head off • Highlights areas for attention • Prevent risks from becoming issues
Identifying & Ranking risk • Identify – How? • Rank risks on probability scale (1=low, 9=high) • Assess impact of risk • High – significant impact on success • Medium –less serious, but costs attached • Low – little effect on project or costs
Impact on Project Probability
Quantitative risk evaluation • Lots of different methods • Catastrophe theory • Game theory • Monte-Carlo simulation • Pert Analysis (read about this from the core text) • Decision Trees • Expected Value • Sensitivity analysis • Failure Mode Effect Analysis
Decision trees 0.75 £100k A 0.25 £20k 0.5 £200k B 0.5 outcome £0 decision
Expected Value • EV of an event = possible outcomes multiplied by the probability of occurrence • E.g. a project with a 50% chance of increasing profit by £50k = 0.5*50k =£25k
Expected Value II • What is the expected value of projects ‘A’ & ‘B’ in the decision tree slide? • Project A • (0.75*100)+(0.25*20) =£80k • Project B • (0.5*200)+(0.5*0) =£100k
Sensitivity analysis • Shows the likely change in finance if variables alter • People + materials major costs of projects • How? • Identify the main inputs • Assess the optimistic and pessimistic value
Sensitivity analysis II • Costs: • Materials – 60k • Labour – 20k • Contribution to overheads – 35k • Revenues • Fixed at 120k • Profit = revenue-materials-labour-o/head
Sensitivity analysis III Materials Labour + overheads
Failure Mode Effect Analysis • Consider • How serious a particular ‘failure’ would be? • How likely is it that the problem would go unnoticed? • How likely it is to occur? Total risk = (Seriousness)*(likelihood unnoticed)*(likelihood of occurrence) (Maylor 1999, p132)
Risk Register • Documentation showing all identified risks & control mechanisms to reduce them • Record • Reference • Title & description • Current status • Potential impacts • Risk owner • Actions • Action log
