Homeland Security likes to make standardized formulas for things and uses the following master equation to prioritize projects:
This is my quick synopsis of the values, but you can read the whole document here.
The dollar value of property impacted by an incident and collateral damage. (1 point for each $50,000,000 of property protected).
Basically will this type of technology make Homeland Security look bad. "For example, intrusive inspection technologies may be poorly perceived by the public, while stream-lined unobtrusive techniques may be favorably perceived," DHS says. Projects that may have better political or societal approval get more points. (0 points for “low”; 5 points for “medium”; and 10 points for “high”).
Cost Savings Realized by DHS
Would this make some task more efficient or save the department money? (1 point for each $1,000,000 saved)
Dollars Requested/Spent by DHS
What is the amount of money DHS should spend on this project or that is being requested (1 point for each $1,000,000)
When evaluating a technology, they also take into account, the threat Potential/Probability of occurrence and the Probability of Success.
Threat potential "is based on a percentage from 0.0 to 1.0 and is multiplied against the people and property protected. For example, 0.5 would relate to a 50% probability of success," DHS says. "The probability of success is based on a percentage from 0.0 to 1.0 and is multiplied against the people and property protected. For example, 0.5 would relate to a 50% probability of success."
