Sochi Olympics—What’s the Cost of National Prestige?

The Sochi Olympics was an example of project costs running out of control; so much so that the final price tag (estimated to be more than $50 billion), dwarfed the costs of every other Olympic Games to this point in time.  In addition to picking a questionable, sub-tropical location for the Games, from the very beginning, the process of developing the site was subject to meddling from politicians, including President Vladimir Putin. Another major cost to the final price tag was related to charges of wide-spread corruption, as sub-projects for the Games (such as infrastructure, buildings, and roads) ended up with highly inflated price tags.   This is a great case for general class discussion as we consider the purpose for Olympic Games, the challenges of cost control with critical deadlines that must be adhered to, and the fact that costs are rising for Games to the point where in 2017, Rome, Budapest, and several other cities withdrew their bids to host the 2024 Olympics because they could not trust the final costs and could not justify the value they would gain versus the costs of the project.

Questions

  1. Consider the following statement: “Government-funded projects intended to serve as ‘prestige projects,’ such as the Sochi Olympics, should not be judged on the basis of cost.” Do you agree or disagree with this statement? Why?
  2. Project success is defined as adherence to budget, schedule, functionality (performance), and client satisfaction.  Under these criteria, cite evidence that suggests the Sochi Olympics project was a success and/or failure.
  3. When a project has a “hard gate,” like being ready on time, how does that affect normal success criteria?  Is it fair to judge a project with a critical completion date by normal project success standards?  Why or why not?
  4. Consider the problems with the Rio Olympics sites that quickly occurred following completion of the 2016 Summer Games.  Access the internet to find evidence of the current state of the Sochi Olympic site.  How is it being used and what are the current problems and opportunities for Sochi?Project Management: Achieving Competitive Advantage

    Cost Management

    Cost management has been defined to encompass data collection, cost accounting, and cost control.

    Cost accounting and cost control serve as the chief mechanisms for identifying and maintaining control over project costs.

    Cost estimation processes create a reasonable budget baseline for the project.

    Learning Curves

    Each doubling of output results in a reduction in time to perform the last iteration.

    Where :

    Yx = the time required for the x unit of output

    a = the time required for the initial unit of output

    X = the number of units to be produced

    b = learning curve slope

    Software Project Estimation—Function Points

    Function Point Analysis is a system for estimating the size of software projects based on what the software does.

    Function Points are a standard unit of measure that represents the functional size of a software application.

    Creating a Project Budget

    The budget is a plan that identifies the resources, goals, and schedule that allows a firm to achieve those goals.

    Activity-Based Costing

    Projects use activities and activities use resources.

    Assign costs to activities that use resources.

    Identify cost drivers associated with this activity.

    Compute a cost rate per cost driver unit or transaction.

    Multiply the cost driver rate times the volume of cost

    driver units used by the project.

    Budget Contingencies

    The allocation of extra funds to cover uncertainties and improve the chance of finishing on time.

    Contingencies are needed because:

    Project scope may change

    Murphy’s Law is present

    Cost estimation must anticipate interaction costs

    Normal conditions are rarely encountered

    Copyright © 2019, 2016, 2013 Pearson Education, Inc. All Rights Reserved

    Benefits to Contingency Funding

    Recognizes future contains unknowns

    Adds provision for company plans for an increase in project cost

    Applies contingency fund as an early warning signal to a potential overdrawn budget
