Does the RMAT code, as implemented, perform in the way it was designed to? How should TSA conceptualize the cost-benefits of counterterrorism programs?

RMAT has proven to be of great value to the Transportation Security Administration TSA in driving a more sophisticated understanding of terrorism risks to the air transportation system. The RMAT Model Has Some Gaps Even if the conceptual models on which RMAT is built were sound and comprehensive, the input data requirements exceed what subject matter experts or science can estimate with precision, and the imprecision of those estimates is subject to unknown sources and ranges of error.

RMAT may not be well suited for the kinds of exploratory analysis required for high-stakes decision support, because of its reliance on a large number of uncertain parameters and conceptual models.

The range of threats, vulnerabilities, attack pathways, and consequence estimate components should be broadened if RMAT is to correctly describe terrorism risk to the U.

TSA should not treat RMAT results as credible estimates of terrorism risk to the aviation system but can use those results to better understand the components of terrorism risk and to explore possible influences of system changes on that risk.

This Guide provides an introduction to the All uncertainty produces an exposure to risk processes involved in Project Risk Analysis and which, in project management terms, may cause a Management, offering a simple but robust and failure to: practical framework to help new users get started. Project Risk Analysis and Management can Project Risk Analysis and Management is a be used on all projects, whatever the industry or process designed to remove or reduce the risks environment, and whatever the timescale or which threaten the achievement of project budget.

The next section of this Guide describes the benefits which Project Risk Analysis 2. It should be regarded as an integral Project Risk Analysis and Management is a part of project or business management and not process which enables the analysis and just as a set of tools or techniques.

Properly undertaken it will increase the The Project Risk Analysis and Management likelihood of successful completion of a project to Process cost, time and performance objectives. Experienced risk analysts and managers hold Risks for which there is ample data can be perceptions of this process which are subtle and assessed statistically. However, no two projects diverse. In order to simplify the process this are the same. Often things go wrong for reasons Guide divides the overall process into two unique to a particular project, industry or constituents or stages: working environment.

Because projects invariably involve a Risk Analysis strong technical, engineering, innovative or This stage of the process is generally split strategic content a systematic process has proven into two 'sub-stages'; a qualitative analysis 'sub- preferable to an intuitive approach.

Project Risk stage' that focuses on identification and subjective Analysis and Management has been developed to assessment of risks and a quantitative analysis meet this requirement.

What Is Involved Qualitative Analysis The first step is to recognise that risk exists as a consequence of uncertainty. In any project A Qualitative Analysis allows the main risk there will be risks and uncertainties of various sources or factors to be identified. This can be types as illustrated by the following examples: done, for example, with the aid of check lists, interviews or brainstorming sessions. Iteration between the Risk Analysis and Risk Management stages is likely.

Section 6 of this Guide considers some of the Such techniques can be applied with varying techniques of Project Risk Analysis and levels of effort ranging from modest to Management in more detail. It is recommended that new users start slowly, perhaps even ignoring 4. An initial qualitative analysis is essential. It brings considerable benefit in terms of Benefits understanding the project and its problems The benefits gained from using Project Risk irrespective of whether or not a quantitative Analysis and Management techniques serve not analysis is carried out.

It may also serve to only the project but also other parties such as the highlight possibilities for risk 'closure' i. Some examples of development of a specific plan to deal with a the main benefits are: specific risk issue. Management has been introduced to an Who benefits from its use? Some organisations treat these are more likely to get what they want, costs as an overhead to the organisation, and not when they want it and for a cost they can to the project. As time scope of the work and the commitment to the progresses, the effectiveness of using Project Risk process.

Below are some example costs, time- Analysis and Management tends to diminish, scales and resource requirements for carrying out therefore it is most beneficial to use it in the the process. Cost There are five points in a project where particular benefits can be achieved by using it.

It can also help in deciding percentage of the total project cost, is relatively between various implementation options small. It can be argued that the cost incurred is an for the project. If a quantitative analysis has been partially dependent upon the availability of carried out then the client will be able to information.
