Defining Information Needs

Lecture 01 of CS507 Information Systems introduces the fundamental concept of defining information needs in modern business organizations. In today's fast-paced corporate environment, information serves as a strategic asset indispensable for managerial planning, operational control, and long-term decision making. The lecture explores the distinction between raw data and actionable information, demonstrating that information represents processed data that possesses meaning, context, and relevance for its recipients. Students examine the three primary categories of information sources: primary sources, which involve original, uninterpreted direct observations and raw empirical data; secondary sources, which consist of compiled reports, analytical summaries, and processed accounts of primary events; and tertiary sources, which encompass indexes, bibliographies, and reference databases that organize and catalog primary and secondary materials. Furthermore, the curriculum investigates how organizational information needs evolve across different managerial tiers, from structured operational monitoring to unstructured strategic forecasting. Virtual University students preparing for midterm examinations will encounter key definitions surrounding information attributes, including timeliness, accuracy, completeness, and relevance. Mastery of these concepts is essential for answering objective solved MCQs and subjective questions frequently featured in past papers by Moaaz and Waqar Siddhu.
