This assignment discusses the challenges encountered while implementing an Enterprise Information System (EIS). It highlights the problems with the initial EIS design, including complex user interfaces and unavailable data. The CIO's improvised EIS is also explored, which led to advantages such as easier modification of reports and faster processing. Additionally, the importance of POS data processing, creating favourable customer experiences, and trusted data views are discussed. A Black Book Model is mentioned as a strategic advantage that mixes up data from various sources.
