Other authors make a distinction between "impact evaluation" and "impact assessment." "Impact evaluation" uses empirical techniques to estimate the effects of interventions and their statistical significance, whereas "impact assessment" includes a broader set of methods, including structural simulations and other approaches that cannot test for ...
According to Rossi et al. (2004, p. 222), [8] 'a measure that is poorly chosen or poorly conceived can completely undermine the worth of an impact assessment by producing misleading estimates. Only if outcome measures are valid, reliable and appropriately sensitive can impact assessments be regarded as credible'.
If the assessment is favourable, and the proposed policy is enacted—after a suitable length of time for the policy to gain traction—it might be followed by an impact evaluation; ideally, assessed impacts before the fact and evaluated impacts after the fact are not wildly divergent. In some cases, impact becomes politicized due to a change ...
Monitoring includes the continuous assessment of programmes based on early detailed information on the progress or delay of the ongoing assessed activities. [1] Evaluation involves the examination of the relevance, effectiveness, efficiency and impact of activities in the light of specified objectives. [2]
Measuring the effectiveness of IR systems has been the main focus of IR research, based on test collections combined with evaluation measures. [5] A number of academic conferences have been established that focus specifically on evaluation measures including the Text Retrieval Conference (TREC), Conference and Labs of the Evaluation Forum (CLEF ...
In military science, effectiveness is a criterion used to assess changes determined in the target system, in its behavior, capability, or assets, tied to the attainment of an end state, achievement of an objective, or creation of an effect, [9] while combat effectiveness is: "...the readiness of a military unit to engage in combat based on ...
An economic impact analysis only covers specific types of economic activity. Some social impacts that affect a region's quality of life, such as safety and pollution, may be analyzed as part of a social impact assessment, but not an economic impact analysis, even if the economic value of those factors could be quantified.

Comparative effectiveness research (CER) is the direct comparison of existing health care interventions to determine which work best for which patients and which pose the greatest benefits and harms. The core question of comparative effectiveness research is which treatment works best, for whom, and under what circumstances. [ 1 ]
