A Project Network may be represented using two styles (1) Activity-on-the-node (AON) or (2) Activity-on-the-arc (AOA). See https://www.slideshare.net/DrMahmoudAINaimi1/aoa-and-aon-networks-69802018 for more details. This project in this assignment is described using the AA style. In response to President Tom Backer's request, Maria Hunt (Systems Analyst) began to break down the activities important to systems design of new order system. She began with a listing of tasks, followed by their relationship to one another, their description, and their time and cost to complete (see the following table). Task Node Relationship Description Time (in days) A 1-2 Program spec's 2 B 2-3 Program coding 3 3-10 Program testing 3 D 10-12 System Testing 2 E 2-4 Database spec's 1 F 4-5 File conversion 2 G 5-10 Database testing 2 H 1-6 Equipment spec's 2 T* 4-6 (Dummy task) 0 J 6-7 Vendor selection 1 K 7-10 Installation 2 L 2-8 Procedure spec's 1 M 8-9 Training spec's 1 N 9-10 Training 2 O 9-11 System doc. 2 P 11-12 Final user doc. 1 *A dummy task must be included in the relationship with duration 0.

Create a graphical network diagram showing nodes 1 to 12 with connecting arcs A to P. You may use any graphical software package or scan a hand-drawn sketch and insert it as a picture in the document. 2. Create the "AON table showing activity predecessors
