Risk assessment is used for uncertain events that could have many outcomes and for which there could be significant consequences. Risk is a function of probability of an event (a particular hazard occurring) and the consequences given the event occurs. Probability refers to the likelihood that a hazard will occur. In a qualitative assessment, probability and consequence are not numerically estimated, but are evaluated verbally using qualifiers like high likelihood, low likelihood, etc. Qualitative assessments are good for screening level assessments when comparing/screening multiple alternatives or for when sufficient data is not available to support numerical probability or consequence estimates. Once numbers are inserted into the analysis (either by quantifying the likelihood of a hazard or quantifying the consequences) the analysis transitions to a semi-quantitative or quantitative risk assessment. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Qualitative_techniques">Qualitative techniques</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Qualitative_risk_analysis&amp;action=edit&amp;section=1" title="Edit section: Qualitative techniques"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There are several techniques when performing qualitative risk analysis to determine the probability and impact of risks, including the following: </p> <ul><li><a href="/wiki/Brainstorming" title="Brainstorming">Brainstorming</a>, <a href="/wiki/Interview" title="Interview">interviewing</a>, <a href="/wiki/Delphi_technique" class="mw-redirect" title="Delphi technique">Delphi technique</a></li> <li>Historical data</li> <li>Strength, weakness, opportunity, and threats analysis (<a href="/wiki/SWOT_analysis" title="SWOT analysis">SWOT analysis</a>)</li> <li>Risk rating scales</li></ul> <div class="mw-heading mw-heading2"><h2 id="Developing_rating_scales">Developing rating scales</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Qualitative_risk_analysis&amp;action=edit&amp;section=2" title="Edit section: Developing rating scales"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Assigning probability and impacts to risks is a subjective exercise.
