A marketing firm is planning to conduct a survey of a segment of the potential product audience for one of its customers. The planning process for preparing to conduct the survey consists of six activities, with precedence relationships and activity time estimates as follows: a. Determine all paths through the network from node a to node f and the duration of each. Also indicate the critical path. b. Determine the earliest and latest activity start and finish times. c. Determine the slack for each activity.
The table below contains scheduling data for a software development project to be undertaken in an IT company.
(i) Identify the critical activities and total duration for the project. (ii) Draw a network diagram using the Activity-on-Arrow (AOA) method to depict the flow of the activities showing interdependencies (iii) Using the data provided in the above table, create a float table for the project.
1. A project has been defined to contain the following list of activities along with their required times for completion.
What would happen if activity 6 were revised to take 6 weeks instead of 1 week?
2. Construct a Gantt chart for the project defined in Problem 1.
