5 Terms Quantitative Analysis In finance, someone who applies mathematics, among others stochastic calculus to FinanceThe process of assigning a value to an item
6 Business Impact Analysis A Business Impact Analysis (BIA) is an information-gathering exercise designed to methodically identify:1. The processes or functions performed by an organization 2. The resources required to support each process performed 3. Interdependencies between processes and/or departments 4. The impact of failing to performing a process 5. The criticality of each process 6. A Recovery Time Objective (RTO) for each process 7. A Recovery Point Objective (RPO) for the data that supports each processOften performed as a step in the development of business continuity plans, the BIA, along with Risk Analysis (RA), provides the foundation for developing and selecting a business continuation strategy that will allow the organization to continue to perform critical processes in the event of a disruption
7 Annual Loss Expectancy Annual Loss Expectancy (ALE) - The calculation by which you determine the potential loss that will occur annually.Single Loss Expectancy (SLE) –Annual Rate of Occurrence (ARO) -Annual Loss Expectancy (ALE) = SLE x AROAALE – Acceptable Annual Loss Expectancy – Do you have one?
8 Single Loss Expectancy Single Loss Expectancy is a term related to Risk Management and Risk Assessment. It can be defined as the monetary value expected from the occurrence of a risk on an asset.It is mathematically expressed as:SLE = NA x AVWhere the Asset Value (AV) is a dollar amount and the Number of Assets (NA) is the quantity. The result is a monetary value in the same unit as the Single Loss Expectancy is expressed (euros, dollars, yens, etc).
9 What Define Impact How Detailed to make it Where the data comes from What format will you deliver it inGraphs, charts and other wasted informationKEEP IT SIMPLE!!!!!!!!!
10 Why Qualify actual costs What is the business risk What is the technical risk and why are they differentJustify projects and their spendCost Avoidance
