Question

1.What are the 4 activity dependency types that can be used in a project schedule? Provide a “real world” example of each.

2.A project activity has an effort estimate of 175 person-hours. The estimate was developed with an assumption of an 85% productivity factor. How many FTE workers at 75% productivity would be required to complete the same activity in 5 days?

Please show your work.

3.

Every quarter, a team of accountants at a Fortune 500 company need to gather information from various departments and develop tax forms and reports for both internal and external stakeholder groups

Given the PMBOK definition, are these quarterly efforts projects? Why or why not.

4. What is meant by the term “triple constraint” as applied to project management? What are examples of metrics that could be used to measure performance for each of these three classic project constraints? Give two additional metrics that go beyond the triple constraint that could be used to measure success of project outcomes. What aspect of success do each measure?

5.

A project activity involves digging a large number of post holes deep into the ground. When you ask the team that will be responsible for completing this activity to develop an effort estimate for the project schedule, they respond that the effort is driven significantly by the specific soil conditions.

From history, they tell you that about 20% of the holes will take 20 hours each, 70% of the holes 40 hours and 10% of the holes 100 hours each.

What is your effort estimate for the activity and why?

6.

You are the project manager for a construction project to repave a 3 mile section of highway. The project is planned to coincide with the winter months where the area typically has lots of rain and colder weather making work slow and generally inefficient.

In some years, this area gets unusually good and mild weather where the work would proceed more quickly and without the typical winter delays.

Is the possibility of “good” weather a risk to the project? Why or why not? What, if anything should you do about this possibility?

7.

Project scheduling software tools such as Microsoft Project or Prima Vera (Oracle) are commonly used to store project decisions, capture actual data, show progress and easily update the schedule with approved changes.

Before beginning to input data into Microsoft Project to create a Project Schedule ( Gantt Chart), what project planning tools/techniques should already be completed to facilitate data entry into the tool?

Explanation / Answer

1)

There are four types of task dependencies they are as follows:

Finish-to-Start: In this relationship, task X cannot start until task Y finishes

Breakfast starts only when the cooking is done

Finish-to-Finish: In this relationship, task X cannot finish until task Y finishes.

Design work cannot finish until environmental studies are complete

Start-to-Start: In this relationship, task X cannot start until task Y starts.

You can’t start swimming until the timer starts

Start-to-Finish: In this relationship, task X cannot finish until task Y starts.

Painting cannot finish until Heating has started

2)

Person Hours: 175

No. of days: 5

Person Hours/Day: 35

Assumed Productivity Factor: 85%

Actual Productivity Factor: 75%

Assume that each work day has 8 hours, with the assumed productivity factor the work would be done only for 85% of the time i.e.6.8 hours (85% * 8)

Now with the actual productivity at 75%, the work would be done only for 6 hours (75% * 8)

So we would require (35/6) workers, i.e. 6 Workers are required

3)

Given the PMBOK definition, these are quarterly effort projects. As the effort needs to be made only once in a quarter to get the necessary reports in order.

The Triple Constraint refers to the key attributes that must be handled effectively for successful completion and closure of any project. For thoroughness, the key attributes of the Triple Constraint are itemized as follows:

Time – This refers to the actual time required to produce a deliverable. Which in this case, would be the end result of the project. The amount of time required to produce the deliverable will be directly related to the amount of requirements that are part of the scope along with the amount of resources allocated to the project.

Cost – This is the estimation of the amount of money that will be required to complete the project. It encompasses various things, such as: resources, labor rates for contractors, risk estimates, bills of materials etc. All aspects of the project that have a monetary component are part of the cost.

Scope – These are the functional elements that, when completed, make up the end deliverable for the project. The scope itself is generally identified during the initial stages so as to give the project the best chance of success.
