The CyClon project team has started gathering information necessary to develop a project network—predecessor activities and activity time in days. The results of their meeting are found in the following table:
ActivityDescriptionDurationPredecessor 1CyClon Project 2Design 10 3Procure prototype parts 10 2 4Fabricate parts 8 2 5Assemble prototype 4 3, 4 6Laboratory test 7 5 7Field test 10 6 8Adjust design 6 7 9Order stock components 10 810Order custom components 15 811Assemble test production unit 10 9, 1012Test unit 5 1113Document results 3 12

Part A. Create a network based on the above information. How long will the project take? What is the critical path?

Part B. Upon further review the team recognizes that they missed three finish-to-start lags. Procure prototype parts will involve only 2 days of work but it will take 8 days for the parts to be delivered. Likewise, Order stock components will take 2 days of work and 8 days for delivery and Order custom components 2 days of work and 13 days for delivery.

Reconfigure the CyClon schedule by entering the three finish-to-start lags. What impact did these lags have on the original schedule? On the amount of work required to complete the project?

Part C. Management is still not happy with the schedule and wants the project completed as soon as possible. Unfortunately, they are not willing to approve additional resources. One team member pointed out that the network contained only finish-to-start relationships and that it might be possible to reduce project duration by creating start-to-start lags. After much deliberation the team concluded that the following relationships could be converted into start-to-start lags:

Procure prototype parts could start 6 days after the start of Design.

Fabricate parts could start 9 days after the start of Design.

Laboratory test could begin 1 day after the start of Assemble prototype.

Field test could start 5 days after the start of Laboratory test.

Adjust design could begin 7 days after the start of Field test.

Order stock and Order custom components could begin 5 days after Adjust design.

Test unit could begin 9 days after the start of Assemble test production unit.

Document results could start 3 days after the start of Test unit.

Reconfigure the CyClon schedule by entering all nine start-to-start lags. What impact did these lags have on the original schedule (Part A)? How long will the project take? Is there a change in the critical path? Is there a change in the sensitivity of the network? Why would management like this solution?
