...Introduction Forecasting is a difficult task, no matter if it involves a weather forecast or forecasting the potential of a local small business all the way up to large international corporations. Forecasting, on the basis of an inventory, is formed by statistical data of previous months, years and seasons. Patterns will emerge, allowing a company to be able to determine how to handle on hand inventories which will allow them to keep overhead costs low while still allowing customers maximum access to goods and products. Predicting future needs on the basis of history should give a company a good foundation, but at the end of the day, depending on the industry, it would be counterproductive to solely base judgement on the past. Market fluctuations, change in the value of the dollar and the desires of the consumers may be impossible to judge yet directly affect inventories and profits. Rite Aid has over 4,700 retail pharmacies throughout the country. To simplify the inventory data, a chart has been constructed to indicate the average inventory value of a pharmacy over the course of an entire year. Year 2012 2011 2010 2009 Inventory $3,138.455 $3,158,145 $3,164,239 $3,184,531 The dollar amounts listed for each year represent the average amount, in dollars, of inventory kept at each of the approximately 4,700 stores. Having stated this fact, it is important to recognize that with all statistical data, it must be noted that some stores will have......

...Business Forecasting Coursework Introduction The data of this coursework are business investment in the quarterly series in the manufacturing sector from 1994 to the second quarter of 2008 in UK. In the coursework, firstly analyze the former 50 data to forecast the latter 8 ones and then compare with the real data to see if the forecasting model is a good fit or not. As adopting two different approaches to make the forecasting work, including regression with Dummy Variables method and Box-Jenkins ARIMA method, according to the results, relative comparisons will be made to demonstrate which one is a better choice for this certain question. Then discuss the underlying assumptions of the chosen model and evaluate whether it is sensitive to these assumptions. All the analyses are based on the SPSS software and the graphs are from the output. Part 1. Examine the data To apply certain model to forecast future value, find out the seasonal component, trends and cycles component is the basic job. There are two approaches to examine the data: see the time series plot (chart 1) or use ACF (chart 2). Chart 1 Plot of the data [pic] Chart 2 ACF/PACF of the data [pic][pic] [pic][pic] From both Chart 1 and Chart 2, the drawing conclusion is that the data has trend-cycle and seasonal components.

Forecasting is a process of making statements about events whose actual outcomes (typically) have not yet been observed. Forecasting is a process of predicting or estimating the future based on past and present data. Economic Forecasting is a process of making forecasts based on analysis of past trends and regularities of the economic processes. Economic forecasts can be carried out at a high level of aggregation – for example for GDP, inflation, unemployment or the fiscal deficit – or at a more disaggregated level, for specific sectors of the economy or even specific companies. Economic forecasting provides information about the potential future events and their consequences for the organization. It may not reduce the complications and uncertainty of the future. However, it increases the confidence of the management to make important decisions.   Economic forecasting includes the following steps: 1. Identifying items to be forecast. The items of socio-economic forecasting are the economic processes (for example, inflation, demand, supply), any indicator describing the company activity (for......

...The business world is an ever-changing and evolving environment that affects companies on a daily basis. Forecasting allows managers to plan according to future events and be prepared to use the system accordingly. With a prediction of the future managers reduce uncertainty and develop plans. The historical data is put together and analyzed to determine forecast events. All large companies use forecasting to make important strategic business decision. This helps them save costs and manage their resources effectively. A firm that is prepared for future occurences will have a healthy financial position. Forecast is of great use to a company because it affects several departments throughout the company. Some of the departments affected are: accounting and finance, marketing, operations, human resources, and information systems. Budgeting, sales, production, inventory control, capacity planning, and purchasing make use of forecasting. Accounting and finance use the data collected to estimate future costs, predict profit or loss, and identify resources available. The marketing department uses forecasting to predict prices and create promotions. The operations of a company is able to run smoothly because job schedules, production schedules, capacity planning, inventory planning, and detecting outsourcing needs are predicted ahead of time. Human resources also benefits from forecasting because seasonal or cyclical hiring is scheduled ahead of time. The company’s information......

...Forecasting Brandman University Operations Management September 19, 2014 Introduction Forecasting is a necessary task in the world of business, but which method works best? Now there might not be a one size fits all for forecasting, but there are methods that work best for particular situations. Throughout this paper a scenario will be picked for the qualitative and quantitative methods, this will show merits and shortcomings of both techniques and procedures. Analysis First to be examined is the qualitative method of forecasting. According to, the qualitative forecasting technique is defined as an “estimating method that relies on expert human judgment combined with a rating scale, instead of on hard (measurable and verifiable) data” (BusinessDictionary, 2014). In the maintenance world of the Air Force, the use of qualitative forecasting is used on a daily basis. For example, with a new fiscal year coming the upper echelon of management will be trying to predict where to allocate funds, more specifically at the base I am stationed at, Travis Air Force Base. Working directly with the Air Force Reserve I see how money is spread amongst the squadrons, which then is allocated to the flights. Working in a maintenance shop, damage airplanes are what secure funding. However, we can really predict how heavily damaged a jet will be when it rolls in, this is when qualitative forecasting comes into play. Many factor can come into play when......

...FORECASTING - a method for translating past experience into estimates of the future. Forecasting is the process of making statements about events whose actual outcomes (typically) have not yet been observed. A commonplace example might be estimation of the expected value for some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or alternatively to less formal judgemental methods. Usage can differ between areas of application: for example in hydrology, the terms "forecast" and "forecasting" are sometimes reserved for estimates of values at certain specific future times, while the term "prediction" is used for more general estimates, such as the number of times floods will occur over a long period. Risk and uncertainty are central to forecasting and prediction; it is generally considered good practice to indicate the degree of uncertainty attaching to forecasts. The process of climate change and increasing energy prices has led to the usage of Egain Forecasting of buildings. The method uses Forecasting to reduce the energy needed to heat the building, thus reducing the emission of greenhouse gases. Forecasting is used in the practice of Customer Demand Planning in every day business forecasting for manufacturing companies.

...Forecasting is an important aspect in today’s business world. Every day businesses strive or lose, depending on the successfulness and accurateness of their forecasting. For successful forecasting, the forecaster needs to have a clear understanding of the current business activities, past trends, and the company’s business strategy. Case 5 exhibits key principles on the way financial forecasting is done. Understanding the Financial Relationships of the Business Enterprise Forecasters use current information to predict the future business activities of the company. This information is found on the financial statements of the company. For example, the balance sheet provides a snapshot of the business’ assets, liabilities and equity at a specific point in time, whereas the incomes statement provides a view of the flow of costs during a specific time frame. Financial ratios measure the relationships between various items on the financial statements. By comparing various ratios with those of previous years, trends can be identified. Because many financial ratios tend to be perserved over time, these ratios are very valuable for the forcaster. The forecaster can estimate only one financial statement line item and, by applying this number to the various ratios, he can make a complete forecast. Grounding Business Forecasts in the Reality of the Industry and Macroenvironment An accurate forecast is made by recognizing not only internal data, but also external data. The......

Forecasting -

...What is Forecasting? Forecasting is the process of making statements about events whose actual outcomes have not yet been observed. Forecasting can be seen as a planning tool for managers to attempt to cope with the uncertainty of the future. Managers are constantly trying to predict the future, making decisions in the present that will ensure the continued success of their firms. Managers use forecasts for budgeting purposes. A forecast aids in determining volume of production, inventory needs, labor hours required, cash requirements, and financing needs. A variety of forecasting methods are available. However, consideration has to be given to cost, preparation time, accuracy, and time period. The manager must understand clearly the assumptions on which a particular forecast method is based to obtain maximum benefit. 1 Types of Forecasts Short Term Short-range forecasts typically encompass the immediate future and concern the day to day operations of a firm. A short-term forecast usually only covers a period of a few months and can be considered an “operating” forecast. Medium Term Medium-range forecasts typically span a few months up to a year. A forecast of this length can be considered “tactical” in nature. Long Term Long-range forecasts typically encompass a period longer than 1 to 2 years. These forecasts are considered strategic and are generally related to management’s attempt to plan new products or build new facilities. 2 Forecasting Methods Time......

Based on the projected statements, any firm is able to estimate its future level of Receivables inventory, payables, and other corporate accounts as well as its anticipated profits and borrowing requirements. A brand new company needs to have a sales projection plan, production plan, to put together a pro forma income statement a new company doesn’t have a prior balance sheet, a income statement, cash balance sheet and other budgets plans would be used to secure operating capital and loans from the bank. I as a new company would need to know how much product we need to make, how much each item cost to make, and how much revenue is expected. A family owned company is in the same boat, sales projection, production plan, cash balance and any other plans are needed in this situation. I really don’t see any difference in this situation then a new business. Knowing a family business has a sales plan and budget sheets, is necessary to get lending from the bank and for planning on how to pay personal monthly bills. A long standing company is no different, and then the previous two companies otherwise it would be long standing. Pro forma income statements, cash budget, and other budgets used together equal a pro forma......
