1. Given the following data, give suitable answers for the following:

The goal of activity resource estimating is to assign resources to each activity in the activity list. There are five tools and techniques for estimating activity resources.

1. Expert judgment means bringing in experts who have done this sort of work before and getting their opinions on what resources are needed.

2. Alternative analysis means considering several different options for how you assign resources. This includes varying the number of resources as well as the kind of resources you use. Many times, there's more than one way to accomplish an activity and alternative analysis helps decide among the possibilities.

3. Published estimating data is something that project managers in a lot of industries use to help them figure out how many resources they need. They rely on articles, books, journals, and

periodicals that collect, analyze, and publish data from other

people's projects. 4. Project management software such as Microsoft Project will

often have features designed to help project managers estimate resource needs and constraints and find the best combination of assignments for the project.

5. Bottom-up estimating means breaking down complex activities into pieces and working out the resource assignments for each piece. It is a process of estimating individual activity resource need or cost and then adding these up together to come up with a total estimate. Bottom-up estimating is a very accurate means of estimating, provided the estimates at the schedule activity level are accurate. However, it takes a considerable amount of

time to perform bottom-up estimating because every activity must be assessed and estimated accurately to be included in the bottom-up calculation. The smaller and more detailed the activity, the greater the accuracy and cost of this technique.

In each of the following scenarios of planning Steve and Susan's wedding, determine which of the five activity resource estimation tools and techniques would be used.

a) Sally has to figure out what to do for the music at Steve and Susan's wedding. She considers using a DJ, a rock band, or a string quartet.

b) The latest issue of Wedding Planner's Journal has an article on working with caterers. It includes a table that shows how many waiters work with various guest-list sizes.

c) There's a national wedding consultant who specializes in Caribbean-themed weddings. Sally gets in touch with her to ask about menu options.

d) Sally downloads and fills out a specialized spreadsheet that a project manager developed to help with wedding planning.

e) There's so much work that has to be done to set up the reception hall that Sally has to break it down into five different activities in order to assign jobs.

f) SallyasksSteveandSusantovisitseveraldifferent caterers and sample various potential items for the menu.

g) Sally calls up her friend who knows specifics of the various venues in their area for advice on which one would work best.

h) There are two different catering companies at the wedding. Sally asks the head chef at each of them to give her an estimate of how long it will take each of them to do the job.

i) There's a spreadsheet Sally always uses to figure out how long it takes guest to RSVP. She enters the number of

guests and their zip codes, and it calculates estimates for her.

j) Sally's done four weddings that are very similar to Steve and Susan's, and in all four of them, it took exactly the same amount of time for the caterers to set up the reception hall.
