...Everest Case Analysis Reflections on the Literature William A. Dinger Lipscomb University Author Note This paper was prepared for Leadership and Organizational Behavior, taught by Professor Malcom Howell (Author Email: adinger@gmail.com or wadinger@mail.lipscomb.edu ) Abstract To prepare, lead, or be lead, and complete a major expedition such as climbing Mount Everest is a significant undertaking. Leadership is critical in these endeavors. As is the case with businesses focused on a specific vision, the team must trust the leaders to make the best decision for the group, which sometimes means telling a client No. Pride, arrogance, and ambition can potentially be more barriers to success than someone might realize. Qualities such as ambition and pride can be appealing at first glance, but neither of those qualities served the expedition leaders in this case study. This paper will have comparisons of the events on Everest. Showing how the leaders might have handled things differently with only a few minute changes to their leadership style. There will be prescribed questions answered, then compared to my personal business experiences, explaining how potentially the loss of 15 lives on that fatal expedition could have been avoided. Everest Case Analysis Reflections on the Literature Two, well skilled, guides took a group of less experienced climbers than themselves on an expedition to climb Mount Everest. Fifteen of the thirty seven people climbing on that expedition perished...

...TENERIFE AND MT EVEREST PAPER First and foremost, I would like to discuss Mount Everest regarding the individual level decision-making. The Mount Everest disaster happened due to poor decision, poor judgment, and no reinforcement of the rules regarding how everyone must descend from the Summit by 2:00pm. In addition, the two lead individuals of the expedition, Rob Hall and Scott Fischer were very confident in their ability to bring their clients to the summit. During this adventure, early on, there were obvious issues and signs, such as health issues amongst clients, warning signs of possible bad weather conditions during hike to summit, which they ignored. Moreover, these signs and interruptions lead everyone to believe that there was a possibility, that they would not make a safe return during their descend from the summit. My main concern about this venture was how they both were responsible for everyone getting on top of the summit and failed at taking heed to the warning signs at based camp. Although Hall and Fischer hired all types of individuals they still needed to find out to make sure that everyone that was on this venture was capable to go up to the summit and in good health. In the end both Hall and Fisher lost their lives helping others and still left their clients to survive on their own. Clients that were upon this expedition had concerns but his only concern that he would possibly have to save somebody else during his hike to the summit. They both...

...reporter or celebrity in their group because they were going to be written about and judged, but this was not the case. There were no bias opinions of people. Everyone was taking the same journey, but their fates were all different. It was vital that the climbers be prepared for the trip to the summit. With all of the environmental differences and the way it could affect their health, they must be mentally and physically prepared as well as have all the right equipment. They needed to produce nearly a dozen gallons of water to meet the needs of 8 clients and 3 guides. Hydration is even more important when in a higher elevation. Oxygen canisters regulators and masks breathing that impressed gas were crucial because it is harder to breath in the thin air. Tents would keep the little warmth they had insulated at night, and they needed the appropriate climbing gear of ropes, harnesses, and wardrobe. Mount Everest is the tallest mountain in the world reaching a staggering 29,028 feet. It is located in the Himalayas and creates the border of China and Nepal. According to Encyclopædia Britannica, valleys and alpine vegetation that have been abused by mountaineers surround the mountain. Over the years, reforestation programs have been carried out to reestablish a livable place for the native wildlife of snow leopards, bears, pandas, and more. The vast amount of snow and rocks have been established as one of the seven wonders of the world and a highly attracted tourist sight for mountain climbers...

...“Into Thin Air”, a book written by Jon Krakauer, mountaineer and renowned for his writing of the outdoors, is Krakauer’s account of the deadliest season of Everest. In the beginning of the story, Krakauer writes, “I can attest that nothing I saw early on the afternoon of May 10 suggested that a murderous storm was bearing down,” (Krakauer 5). This quote is foreshadowing what is to come later in the story, and Krakauer suggests that he and other climbers were unaware and unsuspecting of the “murderous storm”. As the story goes on, Krakauer talks about Everest, writing, “I stared at the peak for perhaps thirty minutes, trying to apprehend what it would be like to be standing on that gale-swept vertex,” (Krakauer 59). This quote tells of the presence of Everest, and how large, yet beautiful it is. Krakauer does a good job of letting the reader know what it is like to be looking at the largest mountain in the world. Lastly, Krakauer writes, “I stayed behind to...

...In the Everest disaster of 1996, the expedition leaders, Rob Hall and Scott Fischer were the main cause of deaths. Both leaders, Hall and Fischer seemed convincing that their clients would summit, but events that year on Everest shows otherwise. The actions that led up to this disaster and many deaths include Hall and Fischer ignoring their own set safety precautions, Fischer not having a well-working acclimatization plan, and both expedition leaders hired inexperienced guides for Everest. Rob Hall and Scott Fischer were the main causes of death on Everest in May 1996. Expeditions on Everest have a set of safety guidelines to follow for a reason, otherwise, negative consequences may occur. Hall and Fischer felt assured that they would have another successful year like the previous one, and when Hall realized things were not looking good for his business, he abandoned his own rules. As Krakauer mentioned, “In fact the only people to reach the summit before 2:00 p.m. were Boukreev, Harris, Beidlemean, Adams, Schoening, and me; if Fischer and Hall had been true toothier pre-arranged rules, everyone else would have turned back before the top,” but Hall ignored the set turn around time, and no one really knew much of what was going on with Fischer. Fischer even started summiting really late. Another factor that plays into the guides having responsibility for the deaths on Everest that year is one that is more specific to Fischer, his acclimatization plan. Krakauer claimed,”Depending...

...Everi THE INTERACTION OE COGNITIVE BIAS, PSYCHOLOGICAL SAEETY, AND SYSTEM COMPLEXITY Michael A. Roberto B usiness leaders and scholars have learned important lessons from tragedies such as the Challenger disaster, the Bay of Pigs fiasco, and the Three Mile Island accident.' Similarly, we can leam important lessons about leadership and decision making from the unfortunate events that took place on Mount Everest several years ago. Survivors have offered many competing explanations for this tragedy. While they have focused on the tactical blunders, this research examines the underlying cognitive, interpersonal, and systemic forces that played a role in the incident. This conceptual analysis suggests that cognitive biases, team beliefs about interpersonal risk taking, and system complexity interacted to create a fatal disaster. Incredible achievement and great tragedy unfolded on the treacherous slopes of Everest on May 10, 1996. TVventy-three people reached the summit along the South Col route in Nepal on that day, including Rob Hall and Scott Fischer, two of the world's most skilled and experienced high-altitude climbers. Unfortunately, Hall, Fischer, and three members of their expeditions died as a storm enveloped the mountain during their descent. Others barely escaped with their lives after many hours wandering in the dark while braving subzero temperatures. Hall, the leader of the Adventure Consultants expedition, had established an impressive track...

...Question 1. After understanding and analyzing the tragedy of Mount Everest , May 1996 that took lives of eight climbers during summit attempts, we can conclude that the tragedy may occur due to several root causes whether it is by nature or human error. The major factor that leads to this tragedy is that all the climbers are lack of team work and communication. Even though they are in the same expedition but they have their own individual’s goal, eager to reach at the summit. For example, Jon Krakauer one of the clients of Adventure Consultant said that he felt disconnected from the climbers around him, they were a team in name only. Supposedly, during the acclimatization exercises, the climbers should take time to get to know each other, learn their responsibilities as a team build their confidence and trust to their teammates, instead they were doubting each other whether they could rely own their team member during difficult times. That also might cause this tragedy, which is lack of trust towards team member. One of the potential causes of the tragedy was overconfidence. Overconfidence occurs when leaders believe that their experience, abilities, skill, or maybe even luck, will allow them to overcome any challenge they face. Research has shown that such overconfidence can lead to poor decision making as leaders substitute their own personal skill for careful analysis of the situation and planning. Hall, in particular, may have been prone to overconfidence. He had reached...

...IS550 – Assignment Schwalbe, Kathy (2013-01-01). Information Technology Project Management (Page A.4). Cengage Textbook. Kindle Edition. Task 1 Green computing is the environmentally responsible use of computers and related resources and covers many potential areas of use. This research project was conducted by We Are Big Pharma, Inc. to learn more about green computing technologies and large corporate initiatives. Several green computing areas were researched and our findings are described below: Data center and overall energy efficiency Data centers are huge consumers of energy due to the electrical demands of the hardware components and the cooling systems that are required to maintain the optimal environment for the hardware. Largely because of the high cost of the energy required (estimated at $0.71 per hardware dollar by 2011), many companies are looking for ways to be more energy efficient. IBM expanded a data center in Boulder, Colorado and made the facility 45% more energy efficient than their typical data center. They used their own high-density computing systems with server and storage virtualization in conjunction with energy-efficient power and cooling systems (Brodkin, 2007). Disposal of electronic waste and recycling Electronic waste is a major concern to communities and countries around the world due to the volume of generated waste and the toxic components that may contaminate the ground, water, and impact workers in the waste facilities. Dell is a leader...

...Into Thin Air Have you ever read “Into Thin Air”? I am going to talk about a chapter from the book that I have read. The chapter talks about Jon Krakauer’s journey climbing Mount Everest. Along with his journey, it talks about the events that went with his journey. “Into Thin Air” is a good story that I would recommend to anyone because it teaches you to never give up, to help others, and what it is like to climb Mount Everest. My first point of why “Into Thin Air” is a great story to read is that it teaches you to never give up. My reasoning for this is that Jon Krakauer faced many challenges while climbing Mount Everest, but he never gave up. One challenge that he faced was when he reached Hillary Step.(Krakauer,page 358). Jon reached the top of...

...Jon Krakauer, author and climber, is employed by Outside Magazine to write down an article about the commercialism on Mt. Everest. Krakauer joins the most fatal Mount Everest expedition in history. Krakauer joins the climbing service referred to as adventure Consultants, guided by Rob Hall. The guide service is meant to speed up the adjustment method and guide the climbers with success to the summit of Mt. Everest. The climb is broken into camps: Base Camp, Camp One, Camp Two, Camp three and Camp Four. After spending weeks at Base Camp preparing for the gruesome climb ahead, the group makes several journeys up to the other camps to hurry up the adjustment method. Then, the group makes a summit push. Throughout the climb, Krakauer describes his teammates, his guides and different expeditions on the mountain. He tries to piece together a continual timeline of the events that will occur within the weeks they're on the mountain. All of the climbers have issues adjusting to the altitude, exhausting quickly, losing weight and moving slowly. The climbers' experience in mountain climbing varies greatly from some well qualified cambers, and some who must rely dominantly on the guides. Despite a variety of mishaps, the primary death doesn't truly occur until about hafway through the book. From that time on, death is something all the climbers become well acquainted with. The actual summit push is when everything begins to collapse. Rob Hall appoints a 2:00 pm turn-around time, which means...

...The Old and The New When first reading Harryette Mullen’s tanka on page 101, we can see in our mind’s eye climbers hiking beside dead hikers on Mount Everest. Looking further into the tanka, more meanings are excavated. The climbers represent a new generation of people while the dead represent the past generations that they are trying to surpass. The peak of Everest is the goals, ideals, and innovations the new generation are hoping to achieve, while Everest itself is the journey the climbers go through to achieve their goals. The fatigue represents the old ideals that the newer generation is trying to overcome, while the frozen dead indicates the way the old generation are frozen in their antiquated beliefs and ideals. The first three words in the poem are “Climbers on Everest” (Mullen 101), which initially gives the reader a vision of a rough and turbulent journey for the climbers. The groups that the climbers are referring to are the new generation of young adults struggling on the mountain. The mountain symbolizes life’s journey, which includes a beginning, the main climb, and the peak. This refers to the timeline of humanity, with ideals being changed for the better as one goes up the mountain. Specifically naming Mount Everest paints life as hard and strenuous, as Everest is the highest and most difficult mountain to climb. The climbers are described as being “fixed,” which means that they have a stubborn determination toward reaching their goal, with the word “reaching”...

Entonces, una década más tarde, ocurrió algo extraño. Jon Krakauer escribió Into Thin Air , otro libro sobre la tragedia alpinismo, que se convirtió en un éxito editorial. De repente, Touching the Void comenzó a vender de nuevo. Random House saco una nueva edición, para mantenerse al día con la demanda.
