Through their management strategy, the companies use the human resources as the way to be more competitive. The HR is in parallel with the strategy by the priorities of the company to reach different goals. The human resources permit to develop flexibility into the organization part of a competitive environment. Don’t waste time! Our writers will create an original "Links between Strategy and Human Resources" essay for you Create order Besides that, the management of people is very important in order to keep the knowledge and techniques up. In fact, HRM has a lot to do with the organizational strategy. To reach the goal, a good coordination is needed to be efficient. As we can find in Johnson and Scholes, 2002: 16, the understanding of a strategic position of an organization is relates to managements understanding in terms of the impact of the external environment, the organizations strategic capability and the influence and expectation of its key stakeholders (Strategic human resource management by Mike Millmore, Philip LewisÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦). An evaluation of the company environment has to be done to evaluate the real situation and the one the company want to reach in a long term. The human resources manager needs to have a good knowledge of each sector and the people working in the company. In fact, the way an organization is adapted to its environment will affect its action. I fact, enviro nmental determinism is more important in an evolutionary perspective strategy than in a classical approach (Poole, 1990). It means that environmental factors control the future of an organization and human resources strategy must matched to the organizational strategy determined in order to achieve success. This is kind of the link between the managers and the first line workers. The strategy is elaborated by the top managers and then the HR has to find out the best way to achieve it by looking and examine what has to be done concerning the staff to do it in the best conditions as possible. The management of knowledge is one of the most important parts of the job of the HR. They have to analyze if every competence is in link and update enough to do the job in a most efficient way. So the HRM job is to look for the best performance in the organization. For many organizations HRM is not really strategic. The organizational strategy drives the possible and practical HRM style. HR strategies are shaped by the business strategy. As it is said in Purcell, 2001, HRM will be informed by organizational strategy as well as helping to shape the nature of this strategy. In organizations where there is high commitment or involvement, employees can have input on tactical direction and even strategy. In that case, HRM facilitates the employee input, but the HRM model itself is still driven by the top-down requirements. The practice of HRM needs to be integrated with the overall strategy to ensure effective use of people and provide better results to the organization in terms of ROI (return on investment) for every dollar spent on them. Unless the HRM practice is designed in this way, the firm stands to lose from not utilizing people fully. This doesnt match well with the success of the organization. HRM needs an organization to: Engage in human resource planning Develop required employee competences Ensure required role behavior Promote employee mo tivation This is the four task model illustrated by Schuler and Jackson (1987). In fact, the HR plays a big role in the strategy of a company because it helps motivates people at work. HRM function is to improve workers performances by giving them better working conditions, make them feel belonging to the company, giving them advantages. The goal of organizational strategy is to increase performances to gain more productivity and this is the link. KEY INITIATIVES FOR STRATEGY To make predictions regarding human resources, it is not necessary to implement techniques more or less sophisticated, but rather to help managerial staff to outline new directions and support the new strategy set by the board of executive. HR strategies are management answers to concrete questions. These forecasts provide opportunities and competitiveness through the management of individuals. Prediction in the field of human resources is called strategic when it helps the manager to anticipate and to proceed faster, even during periods of frequent change. The human resources strategy is the mean to match the human resources management and strategic context of business. All strategies have the same characteristics: they allow obtaining an overall direction, involving several programs, several functions of the organization and must be spread over more than a year. But first the HR department has to think about a whole strategy. The context of strategic human resources can be divided into three phases: Evaluation of the Companys environment Example of Development and Implementation of a strategy Controlling if the new strategy can match with employee welfare The first step in a human resources strategy is to be aware of business priorities, compare the HR strategy and business strategy and address gaps between current and desired situation. To define the context of human resources, the first initiative which is necessary is: Conduct an Evaluation of the companys environment That is to say understand the new business strategy and think about the future HR strategy application with it: Evaluate and spot the internal and external changes to the companys business that may affect its future performance Collect all data that suggest future changes Make an analysis of changes expected Evaluate the expected changes, Identify the context of human resources which can evolve due to external factors (Social, political, legislative, demographic, economic, technological) Identify the strengths and weaknesses of the company and its competitors Compare the HR system with other companies (practicing benchmarking) Analyze the future Identify organizational requirements and very long-term competitiveness, Think about the possible failures to prevent Analyze all the possible sources of change that is to say: Internal Environment: Functional efficiency (if possible with numbers), Usual processes, Resources, Organization, Employees an d managers External Environment: Demographic, Legal, Politic, Technologic, International situation, Economic situation (of the country and all others countries related to the company) All other organizations: Clients, Competitors, Vendors / Suppliers, Economic partners, World of work, Unions And then we can understand and formulate a strategy for the company. Example of Development and Implementation of the Strategy This is the level in which strategic direction is reviewed or defined, programs and activities planned and resources allocated. Then implementation of the strategy in which the managerial levers of change is applied to ensure the desired economic results. There are many ways to act because there are several schools, several ways of thinking. As we can read in Strategic Human Resource Management (by Millmore, Lewis, Saunders, Thornhill and Morrow Prentice Hall by Pearson Education 2007 Page 7), Mintzberg (1998) distinguished 4 approaches to strategy: classical, evolutionary and systemic, and these approaches are more finely detailed in 10 schools. More specifically, in strategy development, Purcell (2001) differentiates 3 schools: the design school, the process school and the configuration school (read in Strategic Human Resource Management: A guide to action by Michael Armstrong Kogan Page 3rd Edition 2006 Page 49-50). Lets focus on The Process School, which is interested in how strategies are created. There are 3 ways to develop and implement a strategy in process school: Integrated Process: According Emery Gonin (Gà ©rer les ressources humaines, Pages 245-246, PPUR presses Polytechniques, 2009) there are 4 steps to follow this scheme: First you have to consider development as a mid-term investment, that is to say develop skills of employees rather than abusive recruitment. Then you need an analysis which will anticipate competences needs by creating a sort of database of collective skills of employees, which will be useful to create development pipelines for major staff categories (novices, new staff, expertsÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦) After you can examine the various services of the organization on future skill needs. It will be useful to find out the priority actions in which you could conduct trainings The last step of this process is implement a cycle of individual development, based on regular analysis of performance an d profile of qualifications for the position occupied, a development contract between the employee and his hierarchy, ensuring an ongoing transfer and evaluation. A training plan and an individual training passport will complement these instruments by providing the dimension professional development. We can see that with this process that the economic strategy is covering the whole areas of the organization, including HR. Indeed it is considered as part of the environment evaluation. The business strategy in covering the whole company orientation and HR will just analyze and implement what is ordered. Parallel process: This process involves the entire business strategy will be thought with the HR strategy and vice versa. This time HR problems can influence business strategy and overall results. To implement this type of action you first need to know what performance management is. According Robert Bacal in Performance Management (McGraw-Hill Professional, 1999 Page 3) it i s an ongoing communication process, undertaken in partnership, between an employee and his or her immediate supervisor that involves establishing clear expectations and understanding about: The essentials job functions the employee is expected to do How the employees job contributes to the goals of the organization What doing the job well means in concrete terms How employee and supervisors will work together to sustain, improve, or build on existing employee performance The parallel process implies that you must match the organization with all skills and with the performance management. Separate process: Here the HR strategy is developed as a separate functional plan. The previous economic plans are first analyzed. As Michael Armstrong says in Strategic human resource management: a guide to action (Kogan Page, 1st Edition 2000 Pages 51-52), the separate process is the most common approach, [where] a distinct HR plan is developed. It is both prepared and considered s eparately from the overall business plan. It may be formulated concurrently with strategic planning, before (and an input to), or following (to examine its implications). [ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦] Since the assessment is outside the strategic planning process, consideration of business strategy depends on a review of the current and past business strategies. The value of the HR strategy is therefore governed by the sufficiency (or insufficiency) of the business-related data. This approach perpetuates the notion of HR as a staff-driven, functionally specialist concern. There we focus on HR to evaluate the environment (at the staff, company or economic entity level). The executive board delegates its responsibilities. That is why this technique is most often used, particularly in large companies. Controlling if the new strategy can match with employee welfare To sum up, the human resources strategies can: Develop a more flexible, more adaptable in a competitive environment Gains and sustain competitiveness in the management of individuals. They start from an economic approach (customers, products, competitors) to progressively achieve specific actions and specified programs in terms of human resources (training, recruitment, compensation, etc. ). The result is a strategy that reflects the priorities needed for action. But we cant lose sight of the welfare of employees in these strategies. Aligning employee expectations with the strategy can be possible by keeping in mind some important elements: Managers influence the expectations of employees Communicate on strategy to build expectations, or requests for changes Translate strategies into operational objectives Change the culture of the organization to strengthen the implementation of the strategy. For example: If the new strategy is based on a process of tota l quality management, employees, at all levels, are involved in defined performance requirements, based on analysis of customer needs. The customer may be external or may be other individuals or entities of the company. Through this process, the performance targets are not imposed by management, but shaped by a process of continuous evaluation, feedback, redefinition and continuous improvement. These objectives must be declined at the whole company level, service, and each employee and has to be expressed in terms of results contributing to a higher performance of the company. In this way, everyone see its contribution and can be satisfied with its job. Furthermore it reinforces teamwork and avoids the divisions between hierarchical levels. You can create an entity where everybody works hard for the same goal, with the same spirit and sharing the same culture. Culture is a powerful weapon of competitiveness (q.v. Disney, Apple, Coca-Cola). It can also be an obstacle when it is not i n line with the strategy. The management challenge is to shape the culture, strengthen and put into perspective with the necessary strategy.

The Indian Removal Act Of 1830 - 892 Words

The central focus for this lesson is to have student analyze an injury question, develop a hypothesis and revise that said hypothesis after several data sets to have a specific thesis statement that is specific to all events leading up to the inquiry question. The inquiry question the students are analyzing is; what are the major effects of the Indian Removal Act of 1830? The students will be given several data sets of events that occurred after the act was initiated and draw conclusions and revise their thesis statement as they go. The big idea of this lesson to have students understand the importance of the Indian Removal Act and it is essentially only the beginning of the journey that Indian tribes had to face after the act was initiated. It led to many heartbreaking events that presently effected more than just the five tribes that were directed effected by the act. The data sets also focuses on Andrew Jackson, the president who initiated the act, and the reasons why he make this act affective. The students will be presented with their first data set and that is a video on the Indian removal act and brief overview of the Trail of tears. Based on the video, the students will make an initial thesis statement that is answering the inquiry question; what were the major effects of the Indian Removal Act of 1830? A list will be compiled on the board of any ideas that the students had based on prior knowledge and the first data set.

Knowing the V0 3. Knowing the t BACKGROUND In order to figure out the perfect shot, you are going to need to know what projectile motion is. So really, what is projectile motion? Projectile motion is the curved path (also known as a parabola) an object follows when thrown near the surface of the Earth. It has an initial velocity, but after that, the only force acting on the object is gravity. In order to figure out the perfect shot, you are going to need to know what projectile motion is.

When the object was thrown, the velocity will become zero once it reach the highest point, after that the ball will continue to move forward because the horizontal force still exists. It will continue to move forward until it hit the ground, due to the gravity. So to figure out the perfect angle to shoot the ball at, we will have to use reverse trigonometry. Since we were given the Vix and the Viy, you will need to use the reverse of tangent, also known as arctangent.

The things that affect projectile motion are the power when we release the ball, ball height, and gravity. 2. Benefit of understanding and applying theory of projectile motion in basketball game is your shot release speed will be adjusted according to what height the ball is release from (e. . , from a jump shot or from the floor). That is because you know the difference between the basket height and the release point determines in part how long the ball must be in the air to reach the hoop. Suggesti on: When doing an experiment we have to be more careful and serious, so we get a more accurate result.

Procedures and Apparatus: |Rubber Ball |White sheets of papers | |Metal Track |Water | |Books |Table | |Meter-stick |Stopwatch | Obtain all the apparatus and material needed to proceed with experiment †¢ Set up a ramp using the metal track and a bunch of books at any angle so that the ball will roll off. †¢ Measure the distance from the edge of the table to the end of the ramp. We will write a custom essay sample on Projectile Motion or any similar topic only for you Order Now †¢ Roll the ball down the ramp and off the table but make sure to catch the ball as soon as it leaves the table; do this part 10 times and record the times †¢ Calculate average velocity for this step †¢ Measure the height (vertical distance or the y-axis) of the table. †¢ Using this height, derive t (time) from the uniform accelerated motion in order to obtain the predicted distance x. The next step is to release the ball from the ramp and let it fall off the table to the floor. †¢ Measure the spot on the floor where the ball hits the floor point when the ball rolls off the table. †¢ We positioned a piece of paper on the floor on which the ball marks the spots it hit first; to achieve this we wet the ball with water so the mark will be more evident †¢ Record these distances at least 3 times in and add them up to obtain the actual distance x. †¢ Compare these actual results with the predicted distance, which you obtain in the first part using u niform motion. Summary of Theory: Projectile motion in two dimensions can be predicted by treating the motion as two independent motions; the horizontal (x) component of the motion and the vertical (y) component of the motion. We examined projectile motion by observing a ball rolling down then leaving the ramp, thus becoming a projectile with a horizontal initial velocity. We measured the horizontal and vertical distances that the projectile traveled from the end of the ramp to when it hit the floor my using a meter stick to measure. -The correct equation for the horizontal motion used was: V=? X/t, where ? X is the distance on the horizontal motion and t is the time for each trail. -The equation used to find the time was the derived uniform accelerated motion equation: -t = v2y, where y is the height of the table and g is the acceleration due to gravity g on the vertical motion % Error, actual-predicted x 100% actual Data and Results |Trial |Times(s) |Velocity(m/s) | |1 |00:00:82 |12. 20 | |2 |00:00:83 |12. 05 | |3 |00:00:85 |11. 6 | |4 |00:00:85 |11. 76 | |5 |00:00:82 |12. 20 | |6 |00:00:78 |12. 82 | |7 |00:00:79 |12. 66 | |8 |00:00:88 |11. 36 | |9 |00:00:84 |11. 90 | |10 |00:00:88 |11. 36 | |Maximum Velocity |11. 36m/s | |Minimum Velocity |12. 0m/s | |Average Velocity |12. 01m/s | |Table Height |76. 30cm | |Predicted impact point |47. 32cm | |Minimum impact point distance |44. 76cm | |Maximum impact point distance |50. 51cm | |Actual impact point distance |46. 33cm | |% Error |2. 14% | Conclusions and Observations: Our predicted impact of (distance X) point of 47. 2cm wa s short by only 1cm of the actual X value of 46. 33cm. The impact points were close, so based on these results we support our predicted X value given the collected data from the experiment. I also calculated the % error and it was only 2. 14% and that again confirms our accurate result. One of the reasons for this accurate result was the technique we used to mark the point where the ball hit the floors in which we wet the ball with water so it will leave a mark on the paper place along the meter-stick. Another evidence to support our results was the height of table found from the kinematics’ equations was 76. cm while that actual measured height was 76. 3cm. As we performed the experiment we confirmed that the horizontal acceleration is always zero, but the horizontal distance that the ball covers before striking the ground does depend on initial velocity because we used uniform motion. We also leaned that Velocity in the y-direction is always zero at the beginning of the tra jectory. In other words, the acceleration in the y-direction is constant, a fact that confirms the independence of vertical and horizontal motion. Through this lab, I was able to examine the affect of forces on the trajectory of a moving object. How to cite Projectile Motion, Essay examples Projectile Motion Free Essays I. Introduction This study focuses on the different factors that affect the game results of the throwing events namely, javelin throw, discus throw, and shot put throw. It is observed that during athletic meets, the winner is determined by the farthest throwing distance. We will write a custom essay sample on Projectile Motion or any similar topic only for you Order Now However, this distance does not sum up the outstanding performance of a winning athlete. Several factors are deemed to be essential in strategically winning a throwing event. For instance, an athlete may need more effort in performing as compared to another because of certain physical or strategic hindrances. These hindrances seem to be inexistent when a game is analyzed using the distance covered only. Thus for the purposes of this study, the competition outcome is defined to be the resulting projectile from the throw. In analyzing the projectile, the research is opened to the influences of strategies beyond throwing the farthest. These factors can be grouped into three aspects: the thrown object’s standard measures, the strategy, and the player’s characteristics. First, the projectile allows us to examine the effects of the thrown object’s standard measures to the throwing ability of a player. These measurements include the weight of the object, and its circumference, in the case of the shot put and the discus, or its length, in the case of the javelin. Second, the projectile exposes the possibility of implementing various strategies that may affect the throwing distance, such as the angle of the throw and the velocity of the turn, in the case of the shot put and discus throw, or run, in the case of the javelin throw. Finally, the projectile also somehow illustrates the advantages or disadvantages of the player’s characteristics like height, weight, and body-build. Consequently, the research will not be tied to the distance results of the throwing events. Rather, it will be concerning thee different projectile elements – distance, height, angle, and force – as they are influenced by the aforementioned groups of variables. At the end of the day, this paper will justify the inevitability of standards with regard to the object’s measured properties, and will recommend the best player profile and playing strategy, as supported by the projectile results of conducted experiments.
