You might wish to consult the risk analysis primers by ETQ - www.etq.com and project management primer by wrike.com, see also the attcahed files. The general methodology suggested would be the FMEA (Failure Mode and Effect Analysis). More on evaluating risk in quantitative terms and in terms of money - Douglass W. Hubbard, How to Measure Anything, Wiley,
Dr. Svoboda had some great suggestions. I would further suggest the booklet on Process Safety by the Center for Chemical Process Safety (CCPS) for specific hazards that might be encountered in the project. If you meant risk particular to getting a project done well the Project Management Institute Body of Knowledge contains a wealth of information of mitigating Project Risks.
