There are four risk projection steps:

  • establish a scale that reflects the perceived likelihood of a risk
  • delineate the consequences of the risk
  • estimate the impact of the risk on the project and the product,
  • note the overall accuracy of the risk projection so that there will be no misunderstandings.

Risk Table ๊ตฌ์กฐ

< RMMM >

Mitigation ์™„ํ™” โ€” how can we avoid the risk?

Monitoring ๊ฐ์‹œ โ€” what factors can we track that will enable us to determine if the risk is becoming more or less likely?

Management ๊ด€๋ฆฌ โ€” what contingency plans do we have if the risk becomes a reality? โ†’ e.g., โ€œknowledge transfer modeโ€

For large project, 30-40 risks are identified

 

Pareto 80-20 rule : shows that 80% of risk are in 20% of identified risk.
