IT-business alignment is a persistent information management concern. This paper presents findings from a study which investigated the influence of management practices and strategic choices on the mutual knowledge of IT and business objectives by IT and business executives. The Strategic Alignment Maturity (SAM) assessment instrument was used to assess maturity of management practices and strategic choices to facilitate alignment. Discriminant function equations were developed to estimate the impact of each of the SAM factors on respondents knowing their IT and business objectives. Communication maturity and Governance maturity were the most prominent predictors of employees knowing their objectives.
