project network$-$predecessor activities and activity time in days. The results of

their meeting are found in the following table:

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 com$-$

pleted 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 rela$-$

tionships 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?
