- Scientific assessment- the gathering of info. Data must be collected and experiments of simulations performed to construct a mode, which is a format statement that describes a situation
- Risk analysis- analyze the potential effect of an intervention addressing the questions what could be expected to happen if a particular course of action were followed (pos & neg)
- Public education- informing the public. This involves explaining the problem presenting all the available alternatives for action, and revealing the probable cost and result of each other.
- Political action- select and implementing a course of action should be based on scientific evidence. During political process there are differences of opinions about how this evidence should be interpreted when selecting a specific course of action disagreements are based on considerations rather than scientific evidence.
- Follow through- monitor the result of any action talon.
