Strategic alignment has been viewed as one of the main concerns of management and IT executives. While the importance of alignment and the benefits that can result from it are not questioned, achieving and maintaining alignment is still a major concern facing organizations. This research focuses on the social dimension of alignment, and in particular on the two factors of communication and knowledge sharing. Five IT companies were selected for this empirical case study. The findings of the research revealed that the consistency of communication and knowledge sharing leading to alignment between IT and business objectives is of a high level. However the extent to which they can lead to alignment is affected by other factors that can inhibit or enhance their ability to achieve a seamless alignment outcome.
