Project Management: Activity-on-Node Diagram Construction and Analysis

To create an Activity-on-Node (AON) diagram for the original project and the project with the new activity, we need to understand the dependencies between the activities and the estimated durations. Based on the provided information, we can construct the AON diagrams as follows: AON for the original project: 1.1.1.1 (5d) | V 1.2.0.1 (5d) / V V 1.2.1.1 (3d) 1.2.2.1 (6d) | / V V 1.2.3.1 (2d) | V 1.2.3.2 (3d) / V V 1.2.3.3 (3d) 1.2.3.4 (3d) | V 1.3.1.1 (5d) | V 1.4.1.1 (1d) AON including the new activity (PenTesting): 1.1.1.1 (5d) | V 1.2.0.1 (5d) / V V 1.2.1.1 (3d) 1.2.2.1 (6d) | / V V 1.2.3.1 (2d) | V 1.2.3.2 (3d) / | V | V 1.2.3.5 (4d) 1.2.3.3 (3d) / V V 1.2.3.4 (3d) 1.3.1.1 (5d) | V 1.4.1.1 (1d) Please note that the AON diagrams provided assume that the activities are executed sequentially without any overlap and that all project personnel works on weekends. You can use these AON diagrams to answer the questions in the quiz or perform further analysis based on the project status and schedule provided.
