Abstract: Identification of information needs of top management is discussed in this article by comparing four methods now in use with a new approach, "identification of critical success factors," developed at the Sloan School of Management. The author argues that the CSF method, implemented through a series of two to three interview sessions, helps top management define its own current information needs. Critical success factors are those performance factors which must receive the on-going attention of management if the company is to remain competitive. While not intended for strategic planning purposes, the identification of critical success factors can help top management by: (1) determining where management attention should be directed; (2) developing measures for critical success factors; and (3) determining the amount of information required and thus limiting gathering unnecessary data. The author concludes that the CSF method is both effective and efficient and should be seriously considered by top management as an important tool in assessing data needs.
