...Sun Hydraulics: Leading in Tough Times Case Study Executive Summary Sun Hydraulics, an industry leader of hydraulic valves and manifolds, has seen steady growth over the past eight years. It has been a profitable company throughout the years with varying return on sales. Presently Sun is constrained by declining sales and high labor costs heading into the present recession. The horizontal corporate structure has proven ineffective in ridding itself of low performing employees that are weighing down the company and thus decreasing profitability. It is time for Allen Carlson, president and CEO of Sun Hydraulics Corporation, to address the employees and shareholders of his decision on how Sun plans to deal with labor and profits during these tough times. I recommend that Sun Hydraulics should proceed with layoffs and early retirement plans to effectively and immediately reduce labor costs during the present recession. This approach seen by some as a short-term solution, allows Sun to rid itself of low performers that the present corporate structure has failed to do. Not only will it increase overall moral over time, but also these layoffs will allow current employees to contribute more time towards future growth and less time coaching or babysitting present employees that may be unhappy or underperforming. Organizational Profile/Overview Bob Koski along with another engineer established Sun Hydraulics, describe as the BMW in the Hydraulics Industry, in 1970...

...HRMG 6200 Bob Koski’s business plan for Sun Hydraulics was successful because Bob created an environment that fostered creativity, an essential characteristic for this type of manufacturing business. Although I’ve never experienced working in a horizontal management organization due to the nature of my field, I can appreciate how Bob’s horizontal organization and working in teams created job satisfaction that increased employee self-motivation that ultimately increased productivity which resulted in the success of Sun Hydraulics in a competitive manufacturing market. However, I believe that horizontal management for Sun Hydraulics could inhibit Sun Hydraulics’ national and international expansion. A decentralized structure, working in teams and communicating the organization’s goals can attract really talented creative employees who like to work in an environment that is not restricting. Employees in these organizations can make companies successful once the employees perceive that their skills and talents are well compensated and their job is designed with all or one of the five enrichment motivators. Horizontal organizations that are successful and grow can become chaos since there is a decentralized structure. The total amount of employees, their various personalities and values can make communication very difficult. Hence the reason for Bob Koski limiting the total amount of employees in each location to be less than 250 which can inhibit the growth of the organization...

...Individual analysis to “Sun Hydraulics” After reading the story “Sun Hydraulics”, I am wondering whether this is a real story, or just a literary work that the content is not necessarily based on fact. So my below analysis is based on the assumption that this is a real story. The 10 years successful operation of Sun Hydraulics Corporation was quite special, which most of the business leaders cannot agree with this approach, but Bob Koski made it and achieved the business success by this special approach. The success was because: 1) Bob understood the hierarchy organization and its disadvantages. This helped him to design a more effective organization structure to conduct the business. 2) An effective climate that motivates the people to enjoy the work and allows employees to focus on their job interests. 3) Family groups made people worked very closely and effectively. 4) This “horizontal” structure created the culture that everyone is the owner of the business, which made employee more responsible. In another word, employees felt that they were not only working for the company, but also for themselves. Though Bob and his Sun team achieved lots of successes in the first 10 years, however I do see a lot of challenges on the way. Let me audaciously predict what will happen in the future. Sun will continue standing as an industry leader for maybe 10 more years. But after 1995, when most of Sun’s competitors moved their factories to the cheap-labor countries, those...

...Mike DeFelice -42 Water Supply Summary In this chapter we learned about water supply. Understanding water supply principles is key to fire fighting for a number of different reasons. Knowing the different types of fire hydrants, their water pressure, and how far apart they will be from one another is important in a hazardous situation. There are 4 key principles to water supply systems. These principals are the source of water supply, means of moving water, water treatment facility, water storage and distribution. Sources of water supply in a jurisdiction can be obtained from surface water, ground water, or both. Some examples of surface water are rivers, and lakes. Most ground water supply comes from wells drilled into underground aquifers. The means of moving water has three key methods. These methods are direct pumping system, gravity system, and combination system. Direct pumping systems are water supply systems supplied by a system of pumps. These systems are typically found in industrial and agricultural settings. Gravity systems are water supply systems in which gravity is the driving force that moves the water. Water is elevated above the system in a tank. Combination systems are combinations of both gravity, and direct pump systems. Combination systems are the most common type of municipal water supply systems. Water treatment facilities are places the water goes through to get filtered, and decontaminated so that water can be consumed without causing...

...common concept that every engineers must know before starting their career life. The code of ethics for engineer was created so that engineers can follow these codes and do not attempt to make any error intentionally. It is a set of rules and obligations that set a standard for an engineer’s decision. In other word, the code of ethics required every engineers to be honest, fairness, equity, and must be dedicated to the protection of public health, safety, and welfare. (Engineers, 2007) The short story “The adventure of the Engineer’s thumb” written by Arthur Conan Doyle is a good example regarding engineering’s code of ethics. The story was told to Sherlock Holmes, began in London 1889 about a young hydraulic engineer, Mr. Hatherley. Hatherley was offered to fix a hydraulic machine with a salary of 50 guineas by a person who identified himself as Colonel Lysander Stark. However, the job has to be perform around mid-night although rather to be just around an hour, out of town in Berkshire. Hatherley could not resist to accept a good offer because his gross taking was only 27 pounds 10s every day. Stark wanted the job to be performed at midnight because he did not want his neighbors to acknowledge the valuable of the land around them. There were large deposit of fuller’s earth under the land. Later on, after arriving to Stark’s place and took an inspection of the press machine, Hatherley discovered the floor consist of a large iron trough and the press machine wasn’t only used...

...not be any more rare because of fracturing. Hydraulic fracturing, also referred to as fracking, is a highly controversial process in which shale gas is extracted from the earth by injecting pressurized liquid into a deeper reservoir to fracture rocks. This technique has been widely used by many oil companies in central and eastern states. While proponents argue that it is safe and is needed to reduce America’s greenhouse gas emissions, critics claim that it may be causing earthquakes and are contaminating water systems. Hydraulic fracking is a process that many companies use. “Put simply, hydraulic fracturing...

...What is more important, the cost of oil and gas, or the health of the human race? Horizontal Hydraulic Fracturing, more commonly known as “fracking” remains a relatively uncommon drilling technology. There was only one in fourteen wells drilled in the United States and Canada horizontally in 2002 (Gold). In 2012, six of every ten wells were horizontal. It is a process in which sand, water, and chemicals are used to blast open shale rock to release the gases that are trapped inside. After the vertical depth of the well is achieved, the drilling continues horizontally. Unfortunately, fracking is proven to cause environmental and health problems in humans and animals. It is also a risk to nearby plant life. The risks of fracking do not out way...

...Power Control Unit, Hydraulic - Description Hydraulic power control units (typically referred to as PCUs) are used to position primary (or secondary) flight control surfaces. PCUs are a single assembly (i.e., single part number) that combines individual hydraulic components into an assembly. PCUs perform two critical functions: (1) they position the flight control surface in response to mechanical or electrical commands, and (2) they represent a principle structural element capable of withstanding flight loads and providing protection against flutter (unsteady, aerodynamic loads). The requirements of these two functions make PCU design a challenging task. At the heart of PCU is a servovalve and an actuator (servo actuator). The servovalve can be controlled by a flapper nozzle, jet pipe, solenoid, torque motor or mechanical linkage. Some PCUs contain only a servo actuator. However, PCUs often contain other components to meet performance and failure mode performance criteria. Other components typically found in PCUs are shutoff valves, pressure relief valves, input filter, check valves, and compensator. Another component that is often part of a PCU is one or more servos whose control is based on some performance criteria. These servos can be positioned electronically or by hydraulic pressure (where loss of hydraulic pressure allows a spring to position the servo). A simple PCU is shown in Figure 1. Figure 1 Simple PCU Diagram This PCU shows the pressure input going through...

...total and began to manufacture the bearings and railroad car couplings among other railroad related components. During the war periods 1939 to 1945, production was modified to produce a variety of hydraulic valves for military applications, including submarines. Major capital investments were made in the physical facilities in 1976. Production facilities for manufacturing of the Hydraulics components were substantially expanded. Internally designed hydraulic radial piston type motors were put into production. A major expansion took place in 1980 till 1990. The production of centralized grease lubricating systems was substantially expanded. A newly introduced R&D effort resulted in the design, development, and production of lubrication system. During this period, as a legal Czechoslovakia monopoly, the company specialized in producing systems for heavy equipment manufacturing industries, steel making and mining. Nationalization: In 1948 the company was nationalized and its engineering and manufacturing resources were re-focused on railroad applications. During this nationalization company has changed his focus and starts manufacture the new products like new heating system for railroad cars and manufacturing of centralized grease lubrication system was restarted and hydraulic technology became integral part of It remained nationalized till 1990 and major changes made during last 10 years from 1980 to 1990.
