9. Assessments: Structure, concepts, and methods

Abstract

Assessments are an essential element of proper disaster management. Assessments help to define the damage and changes in functions at the time of the assessment. Assessments are transectional across the longitudinal phases of the disaster. Any intervention should be preceded by an assessment(s). The assessment process is deconstructed into a series of 10 steps: (1) need to know; (2) define the goal(s) and objectives(s) of an assessment; (3) select the appropriate indicators; (4) define the methods to be used for the assessment; (5) develop and test a plan for data collection; (6) train and brief data collectors; (7) gather (collect) the data; (8) synthesise the data and information collected; (9) output information for decision-making; and (10) compare findings with overarching goal and objectives. Steps 7–9 constitute a production process. Understanding this process is essential for identification of points of success and failure in achieving the desired assessment. Assessments require careful selection of indicators. The selected indicators are used throughout the process. Currently, no standardised set of indicators has been validated. Criteria for the composition of assessment teams are provided and common sources of error are discussed. Prior to, during, and following disasters, assessments are directed by the appropriate coordination and control entity.
