Abstract

This article is a subpart of Risk Management but will attempt to describe different approaches to analysing the risk when managing projects, portfolios and programs

Several tools will be mentioned and explained briefly, but (in order to allow the full use of the wiki) not be described in detail

Definition

According to the ISO Guide 73-2009, risk analysis is the “Process to comprehend the nature of risk and to determine the level of risk”

ISO 31000 describes risk analysis as the process which “provides an input to risk evaluation and to decisions on whether risks need to be treated, and on the most appropriate risk treatment strategies and methods”.

This process mentioned is the computational part of risk management where different aspects, variables and factors are used to estimate the risk involved with a specific feature, action, decision, condition ect. The outcome of this computation is a quantified number or percentage which can then be used as an evaluation criterion, determining either which option to select or if it is safe to proceed down the investigated path.


Main features of risk analysis

Input:

Purpose

The purpose is the reason for analysing the risk; it assists with determining the boundaries of the analysis.

Consequences
Likelihood / Probabilities
Existing control features
Effectiveness of existing control features
Causes of risk
Sources of risk
Factors influencing any of the above
Interrelations / Interdependence
Type of risk
Information available
Risk criteria

Output:

Combined Likelihood / probability
Consequences
Confidence in:
Risk level
Sensitivity of result to preconditions and assumptions
Information Uncertainty
Information Availability
Information Quality
Information Quantity
Ongoing relevance of information
Limitations
