In their study of user manager's systems needs, Alloway and Quillard surveyed 529 managers to determine whether current systems supported their information needs. Managers reported that only 44% of the installed base of application systems, most of which were transaction processing systems, were useful. Inquiry systems, which enabled managers to query data bases and to generate reports, and data analysis systems, which provided opportunities for modeling, simulating, and statistical analysis, were overwhelmingly favored by the managers surveyed. However, few of these analysis and inquiry systems existed (Alloway and Quillard, 1983).
