Project Management: AON Diagram, Critical Path, and Schedule Analysis

This project management assignment involves creating an Activity on Node (AON) network diagram, calculating Early Start (ES), Early Finish (EF), Late Start (LS), and Late Finish (LF) times for each activity, identifying the critical path, and developing Gantt charts. The project activities are listed with their durations and predecessors, starting on April 10, 2019, with a seven-day work week. The assignment includes determining the critical path as A-B-F-K-L-M, tabulating activities with ES, LS, EF, LF, Free Float (FF), and Total Float (TF), and presenting the schedule with corresponding dates. The total project duration is calculated to be 42 days, with a completion date of May 21, 2019. The assignment demonstrates a comprehensive understanding of project scheduling and critical path method.
