Asejere Nigeria Limited (ANL) is a leading distributor of fast-moving consumer goods (FMCG) headquartered in Lagos, with regional hubs in Kaduna, Enugu, and Kano. Over the past three years, the company has experienced rapid revenue growth. However, management is increasingly concerned about operational bottlenecks caused by fragmented, legacy software systems and manual record-keeping at its regional hubs. Key issues reported by management include: 1. Reconciliations of daily sales and inventory figures across hubs take up to 10 days at month-end. 2. Regional warehouse managers frequently suffer from stock-outs of high-demand goods while holding excess stock of slow-moving items. 3. The Board of Directors lacks timely summary analytics to assess market share trends or evaluate long-term expansion plans into neighbouring West African countries. In response, the Chief Executive Officer (CEO) has initiated a digital transformation project to deploy an integrated Enterprise Resource Planning (ERP) software that encompasses all tiers of organizational decision-making. You are required to answer the following requirements: (a) Categorize the four main types of Information Systems—Transaction Processing System (TPS), Management Information System (MIS), Decision Support System (DSS), and Executive Information System (EIS)—and explain how each specifically addresses the needs of a distinct management level at ANL. (8 Marks) (b) Evaluate FOUR business benefits and THREE operational or technical risks that ANL faces in transitioning from its fragmented legacy systems to an integrated ERP system. (7 Marks) (c) Recommend FIVE general internal control measures that ANL management should establish to ensure the confidentiality, integrity, and availability of business data in the new information system.
