There are two activities on your schedule: 1) Install server in lab, and 2) Move server into the data center. However, the second task cannot start until the server has run in the lab for five days without failure. This is an example of what?

You are in charge of constructing the Ferris wheel in each town a carnival visits. However, this is something you have never done before, and you are getting different opinions from others on how long it takes. Joe is new and has given you what you believe to be an optimistic estimate of three hours; Bill says it will take 10 hours, which seems too long to you and quite pessimistic. Last, Margie, who is the most experienced at this task, is telling you it will take eight hours. You are not sure whom to believe, so you decide to do three-point estimation (based on beta distribution). Based on this, how many hours will it take you to assemble the Ferris wheel?

During a work breakdown structure meeting, you have decomposed the deliverables into work packages and created your WBS dictionary. However, you now want to decompose the work packages to assist you in estimating, executing, and controlling the project. These decomposed work packages are:

You are attempting to estimate the resources required to assemble the server racks in the new data center you are building.

According to PMBOK, considering multiple options for estimating is an example of what type of resource estimating technique?
