25question Attached Rules Below Perform Certain Calculations Discus

Perform certain calculations discussed in the assigned reading in order to derive an answer for each problem. Use Microsoft Excel to complete each problem and submit a single Excel spreadsheet that contains a separate worksheet (i.e., separate tab) for each problem. Have each worksheet be clearly labeled to identify the associated problem. Show all calculations or other work performed to derive your answer(s) for each problem. Ensure your spreadsheet is fully functional, allowing the reader to see all numerical values and the underlying formulas associated with each calculated value. Label your work in each worksheet to clearly identify the nature of each piece of data or calculated value.

No credit will be granted for problems that are not completed using Excel, for which your Excel worksheet is not fully functional, or for which you have not shown all calculations or work performed. You may refer to course textbooks, supplemental materials, online information, and your notes. Once you complete all calculations and answer the questions, submit your Excel spreadsheet via the provided hyperlink.

Paper For Above instruction

Given the broad scope of the problems, this paper will focus primarily on project management techniques such as network construction, expected time and variance calculations, critical path method (CPM) analysis, and probability assessments for project completion times. These methodologies are key for effective project planning, scheduling, and risk analysis, providing valuable insights into project duration, variability, and likelihood of meeting deadlines.

Network Construction and Critical Path Analysis

The project described involves multiple activities with defined predecessors, durations, and probabilities. Constructing a network diagram is the initial step, illustrating activity sequences and dependencies. This visual representation helps identify the critical path—the longest path through the network—dictating the minimum project duration. Using the data provided, activities A to L are interconnected through dependencies, forming the basis for this analysis.

The next step involves calculating the expected time (te) and variance (σ^2) for each activity. For activities with probabilistic durations, the PERT (Program Evaluation and Review Technique) methodology applies, using three time estimates: optimistic (a), most likely (m), and pessimistic (b). The formulas are:

  • Expected time, te = (a + 4m + b) / 6
  • Variance, σ^2 = [(b - a) / 6]^2

Applying these formulas to each activity provides the necessary data to analyze project timelines.

Subsequently, the project schedule parameters can be determined, including Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), Latest Finish (LF), and slack for each activity. These calculations involve a forward and backward pass through the network, enabling identification of critical activities with zero slack. The critical path, composed of activities with zero slack, determines the shortest possible project duration and helps identify areas where delays could impact project completion.

Probability of Meeting Deadlines

Once the critical path and expected project duration are established, the next step involves assessing the probability of completing the project within specified deadlines (e.g., 70, 80, 90 days). Assuming that the project duration follows a normal distribution, the z-score can be computed:

z = (target time - mean project duration) / standard deviation

Using standard normal distribution tables or software, these z-scores translate into probabilities. This assessment helps project managers understand risks and plan contingencies accordingly.

Application in Project Management

The techniques outlined—network diagram construction, expected time and variance calculation, critical path identification, and probability assessment—are foundational to project management. They facilitate prudent decision-making in scheduling, resource allocation, and risk mitigation, ultimately increasing the likelihood of project success within desired time frames.

Conclusion

Effective project planning necessitates rigorous analysis of activities, dependencies, and uncertainties. By employing methods such as CPM, PERT, and probability calculations, managers can better predict project timelines, identify critical activities, and manage risks associated with delays. These approaches are essential tools in contemporary project management, supporting timely project completion and optimal resource utilization.
