Earned Value Management - Research Paper Example Due to features that allow Earned Value Management (EVM) to fuse scope, cost and schedule tools, it can accurately predict the project outcomes. Safe project forecasting allow for better planning ahead of time and to make necessary adjustments. Moreover, various studies show that project that use EVM techniques have a higher success rate than the projects that don’t use. In addition to these benefits, EVM has also proved useful in substantiating project disputes. Different project managers use EVM according to their specific project requirements; however certain features of EVM are considered essential and can be recognized as the defining criterion for EVM techniques. These implementation features are; The main difference between projects that use EVM and the ones that do not is quantifying processes and their performances. For instance, EVM projects set specific criteria to allocate numbers to any process and its relative performance. This helps in tracking and adjusting overall performance of the project. Usually at the end of each week, the project manager reviews the progress and adds together the planned values (PV) of each individual task to calculate the Earned Value (EV). This review can be done weekly, monthly, or according to the nature of the project. To understand the governing principles of EVM it would be helpful to know that every task of a project earns value. And translating these tasks into numbers helps in analyzing the performance and make appropriate adjustments. As a result, project managers can achieve better project forecasting. Project managers compare earned values with planned values and actual costs for reviewing performance. Such comparisons help project managers and the owners of the project to calculate their return on the money spent. Another feature of EVM that makes it convenient as well as efficient is its ability to measure physical performance in dollar amounts (Kidasa, 2005). This

What's Up with the Weather by Jon Palfreman Essay

What's Up with the Weather by Jon Palfreman - Essay Example Wigly of the National Center for Atmospheric Research, and conservative scientists and industrialists including James Tefril and Fred Singer of George Mason University and Fred Palmer of the Western Fuels Association. The subject : The burning of fossil fuels increases atmospheric carbon dioxide levels, exacerbating the "greenhouse effect." According to Fred Palmer from Western Fuels, "There is no basis to say that more carbon dioxide in the air is going to lead to a catastrophic global warming." But Marty Hobert of New York University states that "If man is going to have a future on this planet, it is absolutely inevitable we must find another source of energy." Tom Wigly of the National Center for Atmospheric Research believes that the time for mankind is near an end, that due to the doubling of carbon dioxide in the atmosphere, the average world temperature will soon rise five degrees Celsius, eight degrees Fahrenheit. Fred Singer and Jamjes Tefril of George Mason University find the data ambiguous. "You're dealing with something that's very complicated," says Teferil. "You're dealing with something where there's legitimate uncertainty in the science." In 1997 Charles Keeling published forty years of observations which showed a rise in carbon dioxide levels from 330 to 370 parts per million, directly attributable to the use of fossil fuels by industry.
