1. For the network diagram shown, with all times indicating weeks, pls answer the following questions: (questions are independent of each other)

a.. What is the impact on the end date of the project if activity C slips by 2 weeks?

b. What is the impact on the end date of the project if activity E slips by 1 week?

c. What is the impact on activity G if activity C and activity D were to slip by one week each?

d. What is the impact on the end date of the project if activity G is determined to be redundant and is eliminated?

2. The following project is to be scheduled using the expected durations calculated from the following table. All duration estimates are in weeks. (NOTE: Pls round final answers to 2 decimal places.)

a. Find the early start, late start, early finish and late finish for each activity as well as its free slack.

b. What is the critical path duration? What is the variance for the critical path?

c. What is the expected time for the 68, 95 and 99 percent completion limits?

d. What would be the impact on the duration of the project if activity E were 9 weeks?

e. What would be the impact on the slack/float for activity F if the duration of activity E were 9 weeks?

3. Background: Web-based reporting initiative

You work for a company called XTC Pharma, LLC, a small, entrepreneurial company run largely along functional lines by the founding executive team. Your role is as an internal consultant, and your expertise is in technology, management and process. You report directly to the VP of business operations. XTC Pharma LLC employs a large number of sales reps who market (& sell) your company's products to physicians and healthcare organizations. Each sales rep is assigned to a specific state that is part of one of four regions in the US. To enable the V.P. of Sales & Marketing to monitor the number and amount of sales for each representative, for each state and for each region, you have been tasked with the web-based reporting system initiative. You are told that you have a $200k budget and a deadline of 6 months.

As XTC Pharma LLC has grown in headcount, several members of the executive team are feeling as though they are losing control over decision-making and have recently become interested in using a more formal project management methodology in the organization. The problem Is that not everyone agrees, and several members complain that formal project management In a small-to-medium-size organization is Just "costly management overhead? For example, one member has argued that only cross-functional initiatives that last years and have multi-million dollar budgets are projects and require project management "We typically run multi-year drug development trials that last 5 to 7 years and cost tens of millions of dollars. Now those are projects! You're going to pull the organization's attention away from these to focus on a $10,000 project that lasts--What?--a week?"

Given your role In the organization they have asked for your insight. Do project's have minimum budgets or durations? Does this executive team member have a point? Do all projects require the same project management? In order to provide greater clarity, you've been asked to:

Your web-based reporting project (see Q1) had an initial budget of $200.000. While performing schedule performance analysis, you find out that:
• You should have spent $60,000 until now based on hours of schedule activities

• You spent $75,000 until now to perform hours of work that should have cost you $45,000 based on your initial plans

• Assume the remaining work will be done at the same efficiency rate

For this scenario.
a. What is the Planned Value (PV) of the work performed up to this point in time?

b. What is the Actual Cost (AC) of the work performed up to this point in time?

c. What is the Earned Value (EV) of the work performed up to this point in time?

d. What is the Budget-at-Completion (BAC)?

e. Calculate the CPI.

f. Calculate the SPI.

g. Calculate the Estimate to Complete (ETC).

h. Calculate the Estimate at Completion (EAC).

i. Calculate the To-complete Performance Index (TCPI).

j. Based on these calculations, what is your analysis of the current project performance? (As part of your response pls be sure to address both schedule and cost performance.)
