Sheet3 PMAN635- Fall 2020 Session 5 Individual Assignment – IA-5

Answer/complete both of the following two questions. Submit your work products through the appropriate assignments folder by the close of the session. Ensure each file you post includes your last name in the file name.

Question 1: Your firm designs training materials for computer training classes, and you have just received a request to bid on a contract to produce a complete set of training manuals for an 8-session class. From previous experience, your firm follows a 90% learning rate. For this contract, it appears that the effort will be substantial, running 400 hours for the first session. Your firm has an average cost of labor of $60/hour and the overhead is expected to run a fixed $1,000 per session. The customer will pay you a flat fixed rate per session (Per Session Price). If your profit markup is 12%, what will be the Total Price, the Per Session Price, and at what session will you break even? Answer the following four questions:

• a. What is the Total Price? This is what you would charge the customer so that you can have your profit markup of 12% over all of your costs. To calculate this, first figure out your cost per each session, add them up, and then add your profit.
• b. What is the Per Session Price? This is the revenue that the customer pays you each time you complete a session. It is calculated by dividing the Total Price by the number of sessions.
• c. What is the Break Even Point? At the beginning, your cost per session is more than your revenue per session. As each session is completed, however, your costs for the session decline so that eventually your cumulative revenue exceeds the cumulative cost. The break-even point is the session at which, for the first time, your revenue exceeds your cost.
• d. Assume you win the contract and your customer likes the training so much, she orders a ninth course at the same price as the first eight. What will your profit be on the 9th course?
• e. If your learning rate was 80%, would your time to produce a second course be more or less than it was at 90%?

Question 2: You have just been assigned as Project Manager (PM) to the Kuraiz-Reconda Fiber Optic Cable (KRFOC) project. You are preparing your cost estimate for the project and your Project Engineer (PE) tells you it will take 425 hours to complete the design effort. Your Finance Manager (FM) tells you that engineering labor is $125 an hour. The PE admits that the 425 hours is just a guess, that under the best circumstances, it may take only 375 hours, and it could take as long as 700 hours. He stands by his estimate that it will normally take 425 hours. The labor rate is uniformly distributed between $100 and $150. Using this information and a tool you mastered at UMGC, Crystal Ball (CB), answer the following two questions:

• a. What is the mean cost of your engineering effort?
• b. What is your new estimate of engineering costs such that you are 95% confident actual costs will be less than this value?

Note: For each question, provide detailed calculations, explanations, and insights. Use credible references and academic sources to support your reasoning. Ensure your presentation is clear, logically organized, and suitable for academic evaluation.

Paper For Above instruction

The assessment of training contract pricing and project cost estimation involve complex considerations, including learning curves, cost modeling, and probabilistic analysis. This paper addresses two core questions: first, estimating the pricing strategy for a multi-session training program with an embedded learning curve, and second, evaluating project costs accounting for uncertain labor durations and rates. Both applications leverage foundational principles in cost management, learning theory, and probabilistic modeling within project management.

Part 1: Cost and Pricing Analysis for a Training Program with Learning Curve

The primary objective in the first scenario is to determine a fair and profitable price for an eight-session training course, factoring in learning effects, fixed overheads, and desired profit margins. The key considerations include calculating the total cost of delivering all sessions, accounting for the decreasing effort per session due to learning, and then deriving the overall price and per-session fee to ensure profitability.

Using the learning curve principle, the effort for each session diminishes based on the initial effort and the learning rate. The initial session requires 400 hours at a cost of $60/hour, with a fixed overhead of $1,000 per session. The cumulative effort for subsequent sessions is calculated by applying the learning curve, where each successive session’s effort is a percentage (90%) of the previous session’s effort (Lientz & Larreba, 2008). The effort for the second session is 400 x 0.9 = 360 hours, and so on, decreasing exponentially across all sessions.

The total effort (in hours) over the eight sessions is obtained by summing the efforts determined via the learning curve. This cumulative effort, multiplied by labor costs, along with fixed overheads, constitutes the total cost base (Shenhar & Dvir, 2007). Specifically, the effort reduction is calculated as:

E_n = E_1 * (learning rate)^(n-1),

where E_1 = 400 hours, learning rate = 0.9, and n = session number.

Summing efforts from session 1 through 8 yields the total labor hours, which, at $60/hour, provides the total variable labor cost. Adding fixed costs gives total costs. To incorporate profit, a markup of 12% is added to this total. Dividing the total cost (including profit) by the number of sessions delivers the per-session rate, and the total accumulated effort indicates the overall price charged.

The break-even point occurs at the session where cumulative revenue surpasses cumulative costs. Given the declining costs per session, the breakeven can be determined by tracking cumulative totals per session until revenues cover costs.

Furthermore, if the customer orders a ninth session at the same rate, the additional profit can be straightforwardly computed as the per-session price minus costs for that session. Adjustments for learning rate changes, such as decreasing to 80%, will ensure a longer or shorter time to produce subsequent courses, affecting overall cost and profit.

This analysis demonstrates how learning curves, combined with cost modeling, inform strategic pricing and resource planning for repetitive training projects.

Part 2: Probabilistic Cost Estimation for Fiber Optic Cable Project

The second scenario underscores the importance of probabilistic modeling in project estimation. The PE’s estimate of 425 hours, with a range from 375 to 700 hours, coupled with a uniform distribution for the labor rate ($100 to $150), requires the application of statistical tools such as the Monte Carlo simulation using Crystal Ball (CB).

The expected (mean) cost calculation begins by recognizing that the design effort hours, having a triangular distribution, averages at a value computed as:

E_hours = (minimum + mode + maximum) / 3,

where minimum = 375 hours, mode = 425 hours (most likely), and maximum = 700 hours (Lindley, 2020). This yields a mean effort estimate:

E_hours = (375 + 425 + 700) / 3 ≈ 500 hours.

The average labor rate, given a uniform distribution between $100 and $150, is:

E_rate = (minimum + maximum) / 2 = ($100 + $150) / 2 = $125 per hour.

Therefore, the mean cost of engineering effort is:

E_cost = E_hours E_rate = 500 125 = $62,500.

To estimate the cost at 95% confidence, we must consider the variability in both effort and rate distributions. Using CB, a simulation with numerous iterations (e.g., 10,000 runs) would generate a distribution of total costs. The resulting data allows us to identify the 95th percentile, which provides a high-confidence upper bound—indicating the cost below which 95% of the simulated outcomes fall (Vose, 2008). This percentile value becomes the new estimate.

The simulation results highlight the significant impact of effort uncertainty and cost variability. Recognizing the conservative nature of project estimation, project managers can buffer estimates accordingly, reducing risk exposure.

In conclusion, probabilistic modeling with tools like Crystal Ball enhances cost accuracy, enabling better decision-making and risk management in project planning. The combined consideration of effort and rate distributions provides a robust framework for forecasting project expenses.
