Instructions Create a precedence diagram model to understand all activities, dependencies, and duration. Create the diagram on LucidCharts and save as a PDF. o Perform a forward pass and backwards pass o Calculate the float/slack o Identify the critical path Answer the questions associated with each exercise Submit both the diagram and questions on Canvas Waterfall vs Sprint Methodology Waterfall and Agile methodologies are two approaches to building software. In the 90's, the Waterfall was used across the industry to build software that would be released only once to customers. It would take years to build the software and any improvements to the platform would years. The Agile methodology, by contrast, aims to launch software to customers every few weeks or so. The product wouldn't be perfect but the goal would be to solicit feedback so that the product would be improved quickly. The thinking is that a company could also develop products quicker and with less cost because user feedback is helping to identify bugs and clarify requirements. Tasks For both Waterfall and Agile methodologies, create a precedence diagram model to understand all activities, dependencies, and duration. Create the diagram on LucidCharts and save as a PDF. o Perform a forward pass and backward pass o Calculate the float/slack o Identify the critical path Calculate the total cost for the entire project for both methodologies Which approach is cheaper? How many days would it take to build the product for both methodologies? As a product manager, which would you want to implement on your team? Why? . . .
