Question

Activity-on-node networks are a visual representation of the flow of a project. They typically indicate precedence relationships, estimated activity durations, and estimated start times. Give two examples of decisions you might make as a manager based on the information within an activity-on-node network.

Answer 1

Based on Activity on Node networks, those are a visual representation of the flow of a project. Here, they will indicate precedence relationships, estimated activity durations and estimated start times. With such Activity on Node, following are the decisions we could take, these are as stated below:

• Here, we can understand that how many days or periods of time project will take at least to finish, here, critical path is maximum time taken or maximum duration path, and project will take the same time that is considered like least time to complete. Hence, we can decide that when we can expect that project will complete by? For example, looking at the AON network diagram, we can decide that project will complete by 24 November, we also can decide to follow such diagram during project executing and we can review any deviation during project execution time and update the network diagram.
• We also can decide that which activities should be crashed when it is necessary, let’s say, we should crash critical path activities first, and we also can decide that activities will be crashed with least extra cash, here, we will be evaluating activities, those are to be crashed. Further, we can decide which activities have more risk or uncertainties. Activity with higher value of standard deviation or variance, will have more uncertainties or risk, here, standard deviation can be calculated using formula, (pessimistic time – optimistic time)/6,
