Make the case for an investment in a data reengineering project. To provide context, individually focus on a specific, data challenge that interests ( or bugs ) you personally. Using one page, create an articulation for making a precise investment. Specify what constitutes the challenge, demonstrating that you understand the nature of the involved systems. Provide some notion of the costs of allowing the challenge to go unaddressed so that your proposed investment dollar value can be evaluated. Document essential components, their functions, and interactions. This should be accomplishing using narrative and illustration. Your diagram should not show what specific changes would improve the system(s).
