a. Starting with a context diagram, draw as many nested DFDs as you consider necessary to represent all of the details of the engineering document management system described in the following narrative. You must draw at least a context diagram and a level-0 diagram. In drawing these diagrams, if you discover that the narrative is incomplete, make up reasonable explanations to complete the story. Provide these extra explanations along with the diagrams. Projects, Inc. is an engineering firm with approximately 500 engineers who provide mechanical engineering assistance to organizations, which requires managing many documents. Projects, Inc. is known for its strong emphasis on change management and quality assurance procedures. The customer provides detailed information when requesting a document through a Web portal. The company liaison (a position within Projects, Inc.) assigns an engineer to write the first draft of the requested document. Upon completion, two peer engineers review the…
