A perspective on work system analysis: classification and evaluation of methods

Abstract

An inclusive model is presented for work system assessment. The focus of this paper is on job content and context with the primary aim of quantitatively establishing a level of risk for the purpose of improving organizational performance and quality of life in the work setting. The scientific literature on job analysis techniques is reviewed with respect to content relative to the inclusive model. Techniques are classified into microassessment, macroassessment and comprehensive methods. The basis for each classification is outlined. Microassessment methods principally focus on a component subset of the inclusive model in detail. Macroassessment methods more broadly evaluate a subset of the component areas. Comprehensive methods incorporate elements of microassessment methods as well as macroassessment methods and address many components of the inclusive model. The methods are then evaluated based on their ability to achieve the fundamental objectives of job analysis as well as the quality criteria of validity, reliability and utility. No method was found to be sufficient in terms of the aforementioned critical criteria.
