The Senior Service College Fellowship program (SSCF) was developed by the Defense Acquisition University (DAU) as a result of a critical need for civilian leaders in acquisition for the Army. As a result of this need, a strategic partnership was formed between DAU, Lawrence Technological University and TACOM LCMC as a regional program in the Detroit area.

SSCF is a competitive, intensive 10-month educational program that provides leadership and acquisition training for GS-14s GS-15s civilians for future senior leadership roles such as Program Managers, Product Managers, Program Executive Officers, and other key senior acquisition positions.  In the Midwest region, Lawrence Technological University was chosen from a number of leading colleges and universities to develop and deliver this academic portion of the program. The program began in July of 2007 and contains core elements of global leadership, research, program management, acquisition and national security. It includes interaction with government and industry through on-site visits, guest speakers, workshops and mentors.

After completing the program, fellows receive a Masters degree in Global Leadership and Management and certificates in acquisition and program management.

 

Welcome to our newest fellows!

The College of Management hosted its first MBA Case Competition on Friday, May 2, 2014. Five groups of students from Dr. Shahram Taj’s capstone class, Global Strategic Management (MBA 6073), analyzed the current situation and future opportunities for Tata Motors, a global motor vehicle company in front of 5 distinguished judges. The student presentations were based on the Case Study, “Can Tata Motors, Ltd. Become a Global Contender in the Automobile Industry?” Among the judges were, Virinder K. Moudgil, Lawrence Technological University President; Warren Harris, President and Chief Operating Officer of Tata Technologies; Rosemary Bayer, Chief Inspiration Office of ardentCause; Janet Ford, Assistant Vice President, Compliance, Consultant, JP Morgan Chase; and Colonel Ronald J. Shun, Chief of Staff/G3, US Army, TACOM.

Tata Motors, Ltd. is a subsidiary of the Tata Group. The Tata Group is India’s largest business conglomerate in seven business sectors (chemicals, IT and communications, consumer products, engineering, materials, services, and energy). Tata has operations in over 80 countries, and in 2011, had gross revenue of $83.5 billion, 58 percent coming from international operations. The Tata Group is India’s largest private-sector employer, with over 425,000 employees. It’s a powerful symbol of India’s emergence as a world economic power.

Tata Motors is India’s largest automobile company. It is the fourth largest truck and bus manufacturer in the world. Tata Motors manufactures vehicles in India, Spain, South Korea, the U.K., Thailand, Morocco, and South Africa. The company purchased the iconic British Jaguar and Land Rover in 2008.

The competition was fierce and two teams were very close in terms of score.

The $400 First Place prize was awarded to Timothy Balogh, Latoshia Hyatt, and Daphne Joachim.

The $200 Second Place prize was awarded to Valerie Cholagh, Brandon Henderson, and Sheila Thomas.

The other students who participated were Wojciech Pilecki, Gloria Seymour, Jeanne Seaman, Tina Zuber, Mark Blanding, Brian Giltinan, Jalbir Singh, Frank Wilson, Toi Avery, Nurayman Aljaroudi, and Nicholas Downing.

Following the luncheon and awards ceremony President Moudgil spoke about the Case Competition and how it distinguishes LTU students from other universities to be able to interpret and think of a solution as well as present in front of a highly successful panel allowing students to experience the Practical Model of Theory and Practice.

Martin Monte (BSET ’98, MBA ’11) Presents to MBA Students for Alumni Week

Comments Off

Strategic Global Management group photo

Alumni Week at Lawrence Technological University was fulfilling for MBA students in Dr. Shahram Taj’s Global Strategic Management class.   On Monday, March 17th, students in the class, most which will be graduating with their MBA’s in May of this year, had the pleasure of receiving a presentation from Martin Monte who is the Engineering Group Manager in the Body Test Laboratory at General Motors North America.  Monte, who attended LTU for both undergraduate and graduate school, told the students how valuable his LTU education has been during his 29-year stint at General Motors.

Monte received his Bachelor’s of Science in Engineering Technology in 1998 and returned to school seven years later, right in the middle of his General Motors career, to obtain his Master’s in Business Administration, which he received in 2011.  During Monday’s presentation, Monte told the MBA students how he has been using his MBA education at his job at GM.  He said that he uses knowledge in the fields of global leadership, global strategic management, management controls and human resources management.  In addition, he uses skills that he developed, as it relates to change management, management information systems and the design and implementation of new products, processes and systems.

Monte not only told the students that his worthwhile MBA degree is being put to use at GM, but he also told students a little about the GM’s global and regional strategies, enabling the students to appreciate and understand how global strategic management is being implemented at GM.   The presentation was very helpful to the students.  One student, Daphne Joachim, was very interested in Monte’s advice for those engineers who also have an MBA.   According to Joachim, “Marty was a Godsend to our class. He’s an engineer with an MBA and I’m an engineer about to complete my MBA.  He gave me advice on crafting my approach to employers and how to show them where my background could be useful.   I’m happy to say he’s a permanent addition to my Linked-In network now.”

Monte’s presentation not only helped the students understand how valuable his MBA education is, and how he is putting it to use at GM, but he also helped the students understand the value of getting that MBA from LTU.   The presentation was an informative and worthwhile example of how an LTU MBA graduate is using his MBA education in an exciting and rewarding career.  In addition, the presentation also helped students understand how a global company like GM is applying the lessons they have learned in Dr. Taj’s Strategic Global Management class.

Novatis Group Case Study Comes to Life for LTU MBA Students

Comments Off



On Monday, February 10th, 2014, under the professorship of Dr. Shahram Taj, several  Lawrence Technological University  (LTU) students presented the Novatis Group,  A Moroccan diaper and hygienic paper products manufacturer, for a case study assignment [Emerald Emerging Markets Case Studies, 2012] for their Global Strategic Management Class (MBA 6073).  A welcome addition to their case study, was the presence of the Novatis Group’s Chief Marketing Officer, Souheil  Badaa, who listened and watched, via videoconferencing, as two groups of students presented their findings and recommendations.

The students were assigned to read a case study on the Novatis Group, which honed in on their Dalaa brand of disposable baby diapers.  The case study had students applying what they learned in the class and using their critical thinking skills to analyze the case, in order to present their findings and recommendations for the Novatis Group’s diaper products.

Dr. Taj, Professor of Business Administration at LTU crossed paths with Badaa when Badaa was an MBA student at the University of St. Thomas, where Taj was teaching.  In 2011, they both facilitated a group of students to go to Badaa’s native Morocco in order to conduct the live case study.

Badaa, who was a welcome guest during the February 10th presentations, provided the class with an overview of his background, some information on the Novatis Group, and his thoughts about studying business in the United States.   After he talked, students delved right into their presentations.   Students then had the once-in-a-lifetime opportunity to hear from someone who is an integral part of the company that they studied, as Badaa gave positive and constructive feedback to their presentations.

One student, Daphne Joachim, was on a team of students who suggested that the company take part in the disposal of the diapers in an effort to become more sustainable.   Joachim thought that the opportunity to make recommendations to the Chief Marketing Officer of the company that she and her team studied, was an amazing one.  “This case presentation to a company’s executive – it was like having my first consulting job,” said Joachim.  “Making the presentation to Mr. Souheil  Badaa made me feel  heard and valued,”  she continued.   “I’m proud of the recommendations we made regarding managing the disposal of diapers in Morocco.  Even if it can’t be implemented right away, we’ve planted a seed.”

The Global Strategic Management class is the last class that MBA candidates have to take in order to receive their degree.   Dr. Taj teaches two different sessions of the class, on Mondays and Tuesdays, at LTU.

How to Interpret Polls–Do Not Forget the Margin of Error and the Sample Size

Comments Off

With the U.S. presidential election on November 6, we are presented with an ever increasing onslaught of political polls and their results. To make a proper interpretation of a poll’s results, three additional variables should be specified in addition to the proportion results: the poll’s margin of error, the desired level of confidence, and the sample size. In this brief essay, I will review the math behind the margin of error in polls to help you with interpretation of polls.

Background Information
The purpose of a poll is to estimate the opinion or behavior of a population from a sample. We work with a sample since contacting the entire population is too time consuming, often too expensive, and can be physically impossible. Several methods of sampling are used, and simple random sampling, systematic sampling, stratified sampling, and cluster sampling are the most widely used methods.

After the sample is selected from the population, a statistic computed from sample information estimates a population parameter.  The statistic computed from the sample that estimates the population parameter is called a point estimate. As an example, the sample mean, , is the point estimate of the population parameter, μ, the population mean. For polls, the sample proportion, ρ, is the point estimate of the population parameter, π, the population proportion.

How Close is the Point Estimate to the Population Parameter?
We now come to the essence of this essay–the confidence interval estimate (CI). A confidence interval estimate is a range of values constructed from sample data so that the population parameter is likely to occur within that range at a specified probability. The specified probability is called the level of confidence, and in most cases of poll results, the level of confidence is set at .95 (i.e., a pollster has a 95% confidence that the true measurement lies within the margin of error). Putting all of this together gives us the following equation:  CI = point estimate ± margin of error

Accordingly, the CI is determined from the margin of error. You’ve seen the margin of error in some poll results, e.g., “The poll has a margin of error plus-minus 3.1 percentage points for the sample.” If the poll determined that ρ = .5, then the CI would be 50% ± 3.1% = 46.9-53.1, i.e., a pollster has a 95% confidence that the true poll results are 46.9% to 53.1%

I will now show how the margin of error is used to determine a poll’s CI and sample size.

How Is the CI Determined in a Poll?
To determine the CI in a poll, we will use the following formula to compute the margin of error: z * standard error. Mathematically, this formula is expressed as:

In this formula, z defines the level of confidence. In polls, the 95% level of confidence gives us a z score of 1.96. Also in polls, we determine the standard error as the maximum standard error by setting the proportion at 50% (ρ = .5).

We plug in these numbers to determine the margin of error at the 95% level of confidence:


Polls that we see in the media use the 95% level of confidence in determining the margin of error. However, statisticians also determine the margin of error using the 90% and 99% levels of confidence, although the 95% l.98evel of confidence is the most common. The margin of error for the 90% confidence level is calculated using a z score of 1.65:

For the 99% confidence level, the margin of error is calculated using a z score of 2.58:

How Is the Sample Size of a Poll Determined?
I noted above that the purpose of a poll is to estimate the opinion of a population from a sample. As researchers, we are interested in the generality of the data in terms of the number of subjects in the population to which the results apply. If a poll has a margin of error of 3.1%, we can use the formula for the margin of error to estimate the size of the sample:

A recent poll from NBC News/Wall Street Journal reported the following poll results:

Obama is ahead of Romney by five points, 49 percent to 44 percent. The full poll was conducted Oct. 17-20 among 1,000 registered voters. The poll has a margin of error plus-minus 3.1 percentage points for the sample of registered voters.

According to the formula above, we can see how the margin of error was calculated from the sample size of n = 1,000 registered voters.

Putting it All Together
A new TIME Poll has Obama holding a 49% to 44% lead over Romney in Ohio. The poll’s margin of error is plus or minus three percentage points. How do we interpret the results of this poll?

First, we estimate the sample size: n = (.98/.03)² = 1,067.

Second, we estimate the CI around each point estimate at the 95% level of confidence. Obama: 46-52     Romney: 41-47.

Finally, we decide that according to the results of this particular poll, a sample of 1,067 people in Ohio are equally likely to vote for Obama or Romney 95 times out of 100 (because the CIs overlap).

Conclusion
I wrote this essay to provide some clarity and perspective on election polls by reviewing the statistics behind polls. I emphasized that the result of a poll must be interpreted along with the poll’s margin of error so that the sample size and CI can be determined.

COM Faculty Attend the 2012 AOM Conference in Boston

1,716 Comments

College of Management faculty Dr. Anne Kohnke, Dr. Jacqueline Stavros, and Dr. Matthew Cole attended the The Academy of Management 2012 Annual Meeting in Boston. The theme of the 2012 program was The Informal Economy:

“The informal economy refers to commercial activities that occur at least partially outside a governing body’s observation, taxation, and regulation. Sociologists Manuel Castell and Alejandro Portes suggest that the “informal economy is…characterized by one central feature: it is unregulated by the institutions of society in a legal and social environment in which similar activities are regulated.” In contrast to the informal economy, the formal economy is comprised of commercial activities that a governing body taxes and monitors for society’s benefit and whose outputs are included in a country’s gross domestic product. For many decades, management scholars have examined research questions that are almost exclusively centered on the organizations and individuals located in the formal economy. That is about to change.”

For students who are not familiar with the AOM, The Academy of Management started in 1936 when Professors Charles L. Jamison of the University of Michigan and William N. Mitchell of the University of Chicago organized a meeting of management educators to discuss and promote the philosophy of management. “The Academy has evolved from an organization of 10 members to an organization of over 17,500 members from over 105 nations. Today, the Academy’s 25 professional divisions and interest groups promote excellence in established management disciplines. Five U.S.-based affiliates, the Eastern, Midwest, Southwest, and Western Academies of Management and the Southern Management Association as well as two international affiliates, the Asia and Iberoamerican Academies of Management, promote the exchange of ideas and provide collaborative opportunities for colleagues sharing a geographic area, language, or cultural identity.”

Graduate management students can join the AOM for $91.00. The annual conference offers excellent opportunities for COM doctoral students to discuss their dissertations and receive critiques from AOM scholars and practitioners, as well as other AOM doctoral students.

In addition to attending informative paper sessions, symposiums, and professional development workshops, Drs. Kohnke, Stavros, and Cole had a great time networking and socializing in Boston.
