Exercise Test yourself. Draw a network diagram, and then answer the following questions. You are the project manager for a new project and have figured out the following dependencies: Activity 1 can start immediately and has an estimated duration of 3 weeks. Activity 2 can start after activity 1 is completed and has an estimated duration of 3 weeks. Activity 3 can start after activity 1 is completed and has an estimated duration of 6 weeks. Activity 4 can start after activity 2 is completed and has an estimated duration of 8 weeks. Activity 5 can start after activity 4 is completed and after activity 3 is completed. This activity takes 4 weeks. 1. What is the duration of the critical path? 2 What is the float of activity 3 ? 3. What is the float of activity 2? 4. What is the float of the path with the longest float? 5. The resource working on activity 3 is replaced with another resource who is less experienced. The activity will now take 10 weeks. How will this affect the project? 6. After some arguing between stakeholders, a new activity 6 is added to the project. It will take 11 weeks to complete and must be completed before activity 5 and after activity 3. Management is concerned that adding the activity will add 11 weeks to the project . Another stakeholder argues the time will be less than 11 weeks. Who is correct? Use the original information (without the change to activity 3 listed in the previous question) to answer this question. 7. Based on the information in question 6, how much longer will the project take
