This report, authored by a student, proposes the implementation of a Decision Support System (DSS) for Lion Company Australia. The report begins with a letter to the sponsor, followed by an executive summary highlighting the need for the DSS to improve decision-making processes. The report analyzes the organizational context of Lion Company, including SWOT and Porter's Five Forces analyses. It identifies the problem of inefficient decision-making due to the lack of a structured information system. The proposal justifies the choice of a DSS, detailing its benefits in improving the existing manual system, creating new business opportunities, and increasing organizational productivity. The report outlines the System Development Life Cycle (SDLC) process, including development, testing, and implementation phases, as well as post-implementation activities and project, change, and risk management strategies. The core argument is that a DSS will enable Lion Company to streamline complex business processes, enhance competitive advantage, and facilitate better decision-making, ultimately leading to improved business outcomes. The appendices include company background information.
