The population of the study was 156 top echelon members of the selected organizations; whereas the sample size was 112 as determined using the Taro Yemen’s formula. Questionnaire was the instrument for data collection. Data were presented using descriptive statistics and hypotheses were tested with the Spearman’s Rank Order Correlation Coefficient and results showed that there is a significant association of three dimensions of information systems with the measures of organizational performance. The study concluded that adoption of information systems in the fast food outlets is capable of bringing about better performance because it allows the organizations to:(1) have hands- on information on virtually every bit of its operations, (2) promotes prudent and transparent resource application and (3) makes organizations to speedily and flexibly respond to service requests. The study recommended that: (1) Organizations should ensure that reasonable attention is accorded the application of information systems in the running of its operations by giving it a priority attention during resource allocations. (2) Staff should be periodically trained on the use of information systems’ supporting technologies so that everyone in the organization can use the systems effectively, and (3) Good systems development experts should be consulted periodically to analyze and design new systems or update existing ones to match with organizations’ current realities. Keywords: Information Systems; Organizational Performance Behavior; Nexus; Empirical INTRODUCTION uick service restaurants in Nigeria are known as fast food outlets where food is used as a collective term for the end products consumers eat or drink (Mustapha et al, 2014). The fast food culture in Nigeria is fast expanding due to continuous urbanization growth, increasing affluence, coupled with the fact that more women are joining the work force. These changes in lifestyles and demographics throughout the country have resulted in the ever increasing demand for fast food restaurants over the last 25 years. The modern fast food industry is highly commercialized and characterized by various pre-formulated procedures with greater emphasis always placed on ensuring certain level of flavor and quality, consistency of products and quick services as expected by customers (Iwarere and Fakokunde, 2011). It is considered not merely as a collection of inputs to satisfy human nutritional requirements, but also possesses a multi- dimensional set of consumer-satisfying attributes such as taste, appearance, security, and convenience. With these, how important is it for fast food outlets to have a workable information system in place? A business information system as defined by Hooper and Page (1997) is “the sum of all the tools, techniques and procedures used by the business to process data”. Within the fast food industry, components of information systems include, computer hardware and software, cooking machinery, lines of authority, food supply chain from farm to table, food development, recipe development, all manpower – chefs, managers, waiters and waitresses, cleaners, farmers, logistics etc. Q
