Management Science MSC3371 – Fall 2019 Forecasting Assignment
As we transition into Week #2 of our study of Management Science, I would like to consider the following case. It is entitled “What’s Happening?” and is taken from a text called "Operations Management" authored by an Ohio State University professor by the name of Lee Krajewski. It reads as follows: Kay and Michael Passe publish "What's Happening?"—a biweekly newspaper to publicize local events. "What's Happening?" has few subscribers; it typically is sold at checkout stands. Much of the revenue comes from advertisers of garage sales and supermarket specials.
In an effort to reduce costs associated with printing too many papers or delivering them to the wrong location, Michael implemented a computerized system to collect sales data. Sales-counter scanners accurately record sales data for each location. Since the system was implemented, total sales volume has steadily declined. Selling advertising space and maintaining shelf space at supermarkets are getting more difficult. Reduced revenue makes controlling costs all the more important.
For each issue, Michael carefully makes a forecast based on sales data collected at each location. Then he orders papers to be printed and distributed in quantities matching the forecast. Michael's forecast reflects a downward trend, which is actually present in the sales data. Now only a few papers are left over at only a few locations. Although the sales forecasts accurately predict the actual sales at most locations, "What's Happening?" is spiraling toward oblivion.
Kay suspects that Michael is doing something wrong in preparing the forecast but can find no mathematical errors. Tell her what is happening. As you craft your advice to Kay, consider the following supplemental questions:
a.) What forecasting technique do you think Michael is using?
b.) What technique would you use?
c.) Why the downward spiral?
d.) What is the inevitable outcome of not doing anything differently with this forecast? Why so?
e.) How to correct the problem—quickly, with limited financial or human resources?
f.) What is the primary lesson of this case?

The scenario presented in this case revolves around a classic issue of forecasting and its impact on business viability. Michael's approach, while seemingly rational based on historical data, inadvertently initiates a downward spiral that threatens the survival of "What's Happening?". To analyze this situation comprehensively, it is essential to understand the forecasting technique applied, its limitations, and the ramifications of relying solely on historical sales data.
Michael is likely employing a naive forecasting method, which involves projecting past sales data into the future without adjustments for trend or other external factors. Naive forecasting typically assumes that future sales will mirror past sales, making it suitable only for stable, non-trending data. Given that total sales volume has been declining steadily, this technique inherently predicts continued decline, reinforcing the downward trajectory. This is where the problem begins: if forecasted print orders decline in tandem with actual sales, the publisher produces fewer papers, resulting in less visibility and awareness, which in turn sustains or accelerates the decline in sales. This feedback loop exemplifies the illusion of accuracy in trends but ignores underlying causes.
The downward spiral occurs because the forecasting method—most likely a simple trend-based or naive forecast—fails to account for external factors influencing sales, such as market saturation, changing consumer preferences, or increased competition. It predicates future sales solely on past data, neglecting that a declining trend may be a sign of market exhaustion or shifting dynamics rather than a steady trend to be perpetuated. As the forecast shows continued decline, and the actual number of newspapers supplied decreases, the distribution and visibility of the product diminish. This reduces advertising revenue further, compounding the sales decline. The closing of opportunities for growth or stabilization becomes inevitable unless corrective measures are undertaken.
If no action is taken, the forecasted decline will persist, ultimately leading to the cessation of publication. The reduced distribution impairs market presence, diminishes advertising appeal, and erodes the newspaper’s relevance; thus, the product may phase out completely. Continued reliance on a flawed forecasting model effectively accelerates the demise of "What's Happening?".
To correct this problem swiftly and with limited resources, the key is to adopt a more sophisticated forecasting method that considers external variables and incorporates flexible strategies. One effective approach would be to use a combination of moving averages and exponential smoothing techniques with trend adjustment to better capture the nature of declining sales and anticipate future changes. Alternatively, integrating a qualitative judgment or market research insights to complement quantitative forecasts can provide a more nuanced understanding. Importantly, implementing a feedback mechanism where forecast errors are analyzed regularly enables continuous improvement of forecast accuracy.
In addition, diversifying revenue streams and exploring new marketing channels may provide a buffer against declining sales. For example, transitioning to digital formats or expanding targeted advertising could help supplement print sales. On the operational side, adjusting inventory and distribution parameters based on real-time data will prevent overproduction, thus avoiding the spiral of decline.
The primary lesson from this case is the critical importance of selecting an appropriate forecasting model that accounts for trends, external influences, and market dynamics. Relying solely on historical sales data without considering these factors can lead to self-fulfilling prophecies that expedite decline. Effective management involves not only choosing suitable forecasting techniques but also being adaptive and receptive to feedback and market signals. Managers must recognize that data-driven decision-making requires contextually aware models and a willingness to revise strategies as new information emerges.
