Chipotle Mexican Grill's Strategy in 2018: Will the New CEO Be Able to Rebuild Customer Trust and Revive Sales Growth? Arthur A. Thompson The University of Alabama Headed into August 2015, Chipotle (pronounced chi-POAT-lay) Mexican Grill's future looked rosy. Sales and profits in the first six months of 2015 were at record-setting levels, and expectations were that 2015 would be the company's best year ever. But a series of events occurred over the next five months that alarmed customers, drove down sales at Chipotle restaurants, and proved frustrating for Chipotle top executives to fix. • In August, a salmonella outbreak in Minnesota sickened 64 people who had eaten at a ChipotleMexican Grill. The state's Department of Health later linked the illness to contaminated tomatoesserved at the restaurant.• In August, 80 customers and 18 employees at a Chipotle Mexican Grill in Southern California reportedgastrointestinal symptoms of nausea, vomiting, and diarrhea that medical authorities and county healthofficials attributed to “norovirus." Norovirus is a highly contagious bug spread by contaminated food,improper hygiene, and contact with contaminated surfaces; the virus causes inflammation of thestomach or intestines, leading to stomach pain, nausea, diarrhea, and vomiting. After the reported foodpoisoning, the restaurant voluntarily closed, threw out all remaining food products, and sent home theaffected employees. Employees who tested positive for norovirus remained off duty until they werecleared to return to work. County health officials also inspected the facility on two occasions andrendered passing grades, despite finding several minor violations. The restaurant reopened thefollowing day, and no further food poisoning incidents occurred.• In October, 55 people became ill from food poisoning after eating at 11 Chipotle locations in thePortland, Oregon, and Seattle, Wof E. coli bacteria typically associated with contaminated food. Most ill people had eaten many of thesame food items, but subsequent testing of the ingredients at the 11 Chipotle restaurants did not revealany E. coli contamination. (When a restaurant serves foods with several ingredients that are mixed orcooked together and then used in multiple menu items, it is difficult for medical studies to pinpoint thespecific ingredient or ingredients that might be contaminated.) State and federal regulatory officialsreviewed Chipotle's distribution records but were unable to identify a single food item or ingredientthat could explain the outbreak. Nonetheless, out of an abundance of caution, Chipotle managementvoluntarily closed all 43 Chipotle locations in the Portland and Seattle markets, pending acomprehensive review of Page C-121the causes underlying the food contamination and a check ofwhether any of Chipotle's food suppliers were at fault. Chipotle management worked in closeconsultation and collaboration with state and federal health and food safety officials (includingpersonnel from the Centers for Disease Control and Prevention, the U.S. Department of Agriculture'sFood Safety and Inspection Service, and the U.S. Food and Drug Administration) throughout theirinvestigation of the incident and also launched a massive internal effort review of the company's foodpreparation and food safety procedures. These internal actions included:ington areas. Medical authorities attributed the illnesses to a strain 1. Confirming that more than 2,500 tests of Chipotle's food, restaurant surfaces, and equipment all showed no E. coli.2. Confirming that no employees in the affected restaurants were sickened from the incident.3. Expanding the testing of fresh produce, raw meat, and dairy items prior to restocking restaurants. 4. Implementing additional safety procedures and audits, in all of its 2,000 restaurants to ensure that robust food safety standards were in place.5. Working closely with federal, state, and local government agencies to further ensure that robust food safety standards were in place.6. Replacing all ingredients in the closed restaurants.7. Conducting additional deep cleaning and sanitization in all of its closed restaurants (followed by deep cleaning and sanitization in all restaurants nationwide). Meanwhile, the Federal Drug Administration sought to identify a cause for the outbreak. The FDA's investigation revealed no ingredient-related cause and no evidence that particular suppliers were the source of the outbreak. Ultimately, no food item was identified as causing the outbreak and no food item was ruled out as a cause, although fresh produce was suspected as the likely cause.After health officials concluded it was safe to do so, all 43 restaurants in the Portland and Seattle markets reopened in late November 2015, roughly 6 weeks after the incident occurred.• Later, it was confirmed that at least 13 people in nine other states became infected with the same strain of E. coli linked to the Chipotle restaurants in Oregon and Washington states.• In early December 2015, five people in three states-Kansas (1), North Dakota (1), and Oklahoma (3)-became ill after eating at Chipotle Mexican Grill restaurants. Studies conducted by the Centers for Disease Control and Prevention (CDC) determined that all five people were infected with a rare strain of E.coli different from the infections in Oregon, Washington, and nine other states. However,investigators used sophisticated laboratory testing to determine that the DNA footprints of the illnesses in the Midwest were related to those in the Portland and Seattle areas.• In mid-December 2015, about 120 Boston College students became ill after eating at a Chipotle Mexican Grill near the campus, an outbreak that local health officials attributed to a norovirus. Health officials also tested students for E. coli infections but the tests were negative.Extensive reports of the last three incidents in the national media took a toll on customer traffic at most all Chipotle locations. The average decline in sales at Chipotle locations open at least 12 months was a stunning 14.6 percent in the fourth quarter of 2015, causing Chipotle's revenues in Q 4 2015 to be 6.8 percent lower than in the fourth quarter of 2014. The company's stock price crashed from an all-time high of $758 in early August 2015 to $400 heading into 2016.

3. Suppose that a communications network transmits binary digits, 0 or 1, where each digit is transmitted 10 times in succession. During each transmission, the probability is 0.995that the digit entered will be transmitted accurately. In other words, the probability is0.005 that the digit being transmitted will be recorded with the opposite value at the end of the transmission. For each transmission after the first one, the digit entered for transmission is the one that was recorded at the end of the preceding transmission. If Xo denotes the binary digit entering the system, X, the binary digit recorded after the first transmission, X2 the binary digit recorded after the second transmission, and so on, then{X„} is a Markov chain. (a) Construct the (one-step) transition matrix (b) Find the 10-step transition matrix. Use this result to identify the probability that a digit entering the network will be recorded accurately after the last transmission. (c) Suppose that the network is redesigned to improve the probability that a single trans-mission will be accurate from 0.995 to 0.998. Repeat part (b) to find the new prob-ability that a digit entering the network will be recorded accurately after the last transmission.1

Discuss the application of the Routh-Hurwitz stability criterion in control system analysis. What are its main limitations?I6 marke1 What is a transfer function? Discuss its main characteristics. Consider the armature-controlled DC motor shown in Figure 2.1. The electrical system is represented by an armature circuit, in which ua is the applied armature voltage, ia the armature current, Ra the armature resistance, La the armature inductance and eb is the back electromotive force generated in the armature. The mechanical part is represented by a rotational system, in whichJ is the moment of inertia due to the rotor and the load, B the viscous rotational damping associated with the load, 0 is the angular position, Tm is the torque produced by the motor and TI, is the load torque. The system is modelled by the following differential and algebraic equations \begin{aligned} R_{a} i_{\alpha}(l)+L_{a} \frac{\mathrm{d} i_{a}(t)}{\mathrm{d} t}+e_{b}(t) &=v_{a}(t) \\ J \frac{\mathrm{d}^{2} \theta(t)}{\mathrm{d} t^{2}}+B \frac{\mathrm{d} \theta(t)}{\mathrm{d} t} &=\tau_{m}(t)-\tau_{L}(t) \\ e_{b}(t) &=K_{L} \omega(t) \\ \tau_{n}(t) &=K_{T} i_{a}(t) \end{aligned} where KE is the back electromotive force constant of the motor, Kr is the torque constant of the motor, and w is the angular velocity. Obtain a state-space representation of the armature-controlled DC motor if the state variables are the armature current and the angular velocity, the inputs to the system are the armature voltage and the load torque, and the only output is the angular velocity. Clearly identify matrices A, B, C and D. [Hint: The derivative of angular position is angular velocity and the derivative of angular velocity is angular acceleration].

2. The state of a particular continuous time Markov chain is defined as the number of jobs currently at a certain work center, where a maximum of two jobs are allowed. Jobs arrive individually. Whenever fewer than two jobs are present, the next arrival occurs at a mean rate of one in two days (i.e., job arrival rate one at a time, at a mean rate of one per three days (i.e., job completion rate = 1/3), and then leave immediately.1/2). Jobs are processed at the work center (a) Develop the diagram for this Markov chain. (b) Write down time-dependent ordinary differential equations for this Markov chain. (c) Construct the steady-state equations. (d) Determine the the steady-state probabilities.

As Bo was helping one of the lambs, the Big Bad Wolf (“Wolf") slithered into the pasture Assault Battery O Assault & Battery O False Imprisonment O Conversion O Trespass to Land O Trespass to Chattels O No Intentional Tort Read through this fact pattern and try to identify any potential tortious conduct. Once you have read through the document –complete the multiple-choice assignment on Blackboard. Little Bo Peep (“Bo") was busy tending her sheep in the sheep pasture that she had rented from the Farmer in the Dell. As Bo was helping one of the lambs, the Big Bad Wolf ("Wolf") slithered into the pasture, grabbed two of Bo's sheep (each worth approximately $50.00)and ran away with them. Bo, a former high school track star, sprinted after Wolf to retrieve her sheep. However, before she could catch up with him,Wolf gobbled down one of the sheep. When Bo caught up to the Wolf, she reached out and grabbed his arm to stop him from eating the remaining sheep, roughly jerking him around to face her. Wolf stumbled and fell,breaking his arm. Bo threatened to bash Wolf with her Shepherd's staff if he moved an inch. She was holding him until the local law enforcement arrived. Bo used her cell phone to call her husband, Little Boy Blue (“Boy Blue"), as well as the police. The police arrived right away and arrested Wolf for larceny.In the meantime, Boy Blue, upon hearing the tale from his wife,jumped into his car and sped to the meadow. Unfortunately for Boy Blue,he failed to pay attention and rear-ended the car in front of him, which was stopped at a red light. The driver of the car, Jack Sprat (“Jack") was not hurt, but his car was severely damaged. Jack became enraged and jumped out of his car. He ran up to Boy Blue and punched him in the face,breaking Boy Blue's nose; Jack continued to pummel Boy Blue even after Boy was lying helplessly on the ground. A witness to the accident, Little Miss Muffet ("Miss") grabbed her semi-automatic pistol and ran up to Jack shouting, "If you don't back off of him, I'm going to shoot you in the arm!" Jack, fearing for his life, backed away from Boy Blue, and Miss put her gun away. The police arrived, arrested Jack, and called an ambulance for Boy Blue. Boy Blue ended upon being fine, except for the broken nose.The next day, Bo went looking for Jack Sprat. She saw Jack walking down the street. She confronted Jack, shook her shepherd's staff at him and yelled, "I ought to break your nose for what you did to Boy Blue!"Jack backed away, mumbled, “I'm sorry", and took off running in the other direction. When Bo went home and told Boy Blue what she had done, he grabbed her in a bear hug, crushed her to his chest and planted a big kiss on her lips! Bo exclaimed, "Ouch, you're hurting me!" and Boy Blue immediately apologized.
