Evidence informed policymaking (EIPM) is an approach that ensures
decision-making is well informed by the best available evidence. A
number of studies show that most policy failures and inconsistencies are
largely caused by, either a lack of evidence, or a lack of rigor in
evidence used to create or review policies. EIPM, therefore, requires
systematic and transparent access to, and appraisal of, evidence as part
of the policymaking process.
