How do you categorize incidents in ITIL?
According to ITIL, the goal of Incident classification and Initial support is to:
- Specify the service with which the Incident is related.
- Associate the incident with a Service Level Agreement (SLA )
- Identify the priority based upon the business impact.
- Define what questions should be asked or information checked.
What is problem management process in ITIL?
Objective: Problem Management aims to manage the lifecycle of all Problems. The primary objectives of this ITIL process are to prevent Incidents from happening, and to minimize the impact of incidents that cannot be prevented.
What is a problem in ITIL?
As ITIL defines it, a problem is “a cause or potential cause of one or more incidents.” And an incident is a single unplanned event that causes a service disruption.
What is the life cycle of problem management?

Why is a fat tail distribution so important?
Fat-tailed distributions are graphical representations of the probability of extreme events being higher than normal. In many domains fat tails are significant, as those extreme events have a higher impact and make the whole normal distribution irrelevant.
What does it mean to have a fat tail?
By definition, fat tails are a statistical phenomenon exhibiting large leptokurtosis. This represents a greater likelihood of extreme events occurring similar to the financial crisis. Since the magnitude of fat tails are so difficult to predict, left tail events can have devastating effects on portfolio returns.
What does it mean when the stock market has a fat tail?
Unfortunately, history would suggest financial markets don’t always act this way and rather, they exhibit fatter tails than traditionally predicted. By definition, fat tails are a statistical phenomenon exhibiting large leptokurtosis. This represents a greater likelihood of extreme events occurring similar to the financial crisis.
Which is the most extreme case of a fat tail?
The most extreme case of a fat tail is given by a distribution whose tail decays like a power law. A variety of Cauchy distributions for various location and scale parameters.
