### Risk drivers

I read about risk drivers for project schedules: see http://www.projectrisk.com/integrated_c ... lysis.html. What is a difference between risk drivers and Event Chain Methodology?

### Re: Risk drivers

Risk drivers or risk events is a component of Event Chain Methodology. Event Chain Methodology is a comprehensive theory of project risk analysis. It includes also:
- state of activities and state tables
- event chains
- event chain diagrams
- resourse allocation using risk events
- execution of mitigation plans based of risk events

### Re: Risk drivers

Event Chain Methodology also includes process of changing probabilistic and impact of risks for activities in progress. At the beginning of activity risk assigned to this activity may have certain probability and impact. Close to the end of activity, probability and impact of risk will be reduced. RiskyProject software handles this effect automatically based on:
a). Moment of risk
b). % completed of the activity
So if you enter risk probability 50%, and you already completed 90% of activity and risk did not occur yet, the chance will be reduced. However you don't need to re-enter or update original probability 50%.

### Re: Risk drivers

Is it possible to define statistical distribution for risk outcomes? For example, I have risk "Financial problems". It can cause delay from 3 to 5 days. It would like to use lognormal distribution for this delay.

### Re: Risk drivers

Yes you can do it. You need to enable statistical distribution for risk outcome in Schedule -> Options -> Risks. Then each time you assign risk to task or resources you can define:
- low outcome
- base outcome (for triangular distribution)
- high outcome
- type of distribution
- distribution parameters depending on distribution type
- seed
