    From this chart we come to know about the effects of advertisement & inflationrate on sales. From this above chart we show only two independent variableswhich effects the sales function1). Advertisement.2). Inflation rate.

    The Relationships Between Sales &Advertisement:

    Advertisement and sales differ greatly, but have the same goal. Advertisingimproves the selling environment and plays a very important role in sales. If theadvertising department generates a list of potential customers, that can benefitsales. Advertising department in an organization has the goal increasing thenumber of interactions between potential customers and the organization.Achieving this goal may involve

    the sales team using promotional techniques such as advertising, salespromotion, publicity, and public relations, creating new sales channels, orcreating new products (new product development), among other things..

    The relatively newfield ofsales process engineering views "sales" as the outputof a larger system, not just as the output of one department. The larger systemincludes many functional areas within an organization. From this perspective,"sales" and "advertising" (among others, such as "customer service") label for anumber of processes whose inputs and outputs supply one another to varying

    degrees. In this context, improving an "output" (such as sales) involves studyingand improving the broader sales process, as in any system, since the componentfunctional areas interact and are interdependent.

    Most large corporations structure their advertising departments in a similarfashion to sales departments and the managers of these teams must coordinateefforts in order to drive profits and business success. For example, an "inbound"focused campaign seeks to drive more customers "through the door", giving thesales department a better chance of selling their product to the consumer. Agood marketing program would address any potential downsides as well.

    The sales department would aim to improve the interaction between thecustomer and the sales facility or mechanism (example, web site) and/orsalesperson. Sales management would break down the selling process and thenincrease the effectiveness of the discrete processes as well as the interaction

    between processes. For example, in many out-bound sales environments, thetypical process includes out-bound calling, the sales pitch, handling objections,opportunity identification, and the close. Each step of the process has sales-related issues, skills, and training needs, as well as advertising solutions toimprove each discrete step, as well as the whole process.

    Many companies find it challenging to get advertising and sales on the samepage. The two departments, although different in nature, handle very similarconcepts and have to work together for sales to be successful. Building a goodrelationship between the two that encourages communication can be the key tosuccess - even in a down economy.

    Demand Forecasting

    A demand forecast is the prediction of what will happen to yourcompany's existing product sales. It would be best to determine thedemand forecast using a multi-functional approach. The inputs fromsales and marketing, finance, and production should be considered. The

    final demand forecast is the consensus of all participating managers.You may also want to put up a Sales and Operations Planning groupcomposed of representatives from the different departments that will betasked to prepare the demand forecast.

    The activity of estimating the quantity of a product or service thatconsumers will purchase. Demand forecasting involves techniquesincluding both informal methods such as educated guesses andquantitative methods such as the use of historical sales data or currentdata from test markets. Demand forecasting may be used in making

    pricing decisions, in assessing future capacity requirements, or inmaking decisions on whether to enter a new market.

    Determination of the demand forecasts is done through the following steps:

    Determine the use of the forecast. Select the items to be forecast. Determine the time horizon of the forecast. Select the forecasting model(s). Gather the data. Make the forecast. Validate and implement results.

    Let us find the value of Y & then forecasted Y:

    y = y / n

    y = 695.28 / 16

    y = 43.46

    t = t / n

    t = 136 / 16

    t = 8.5

    b = (t-t) (y-y) / (t-t) 2

    b = -5007.425 / 404

    b = -13.95

    a = y - bt

    a = 43.455 (-12.395) (10.75)

    a = 35.27 + 133.25

    a = 162.035

    Y = 162.035 - 13.95t

    2010_____4th quarter 20 -116.965

    Explanation:

    The above table shows that the trend in the values of forecasted sales(Y) onquarterly basis is in decreasing order & we say that in a same trend.

    Hence the forecasted values on quarterly basis is:

    QUARTER_1 = 4.419/ 4 = 1.10475

    QUARTER_2 = 0.251 / 4 = 0.06275

    QUARTER_3 = -0.887 / 4 = -0.22175

    QUARTER_4 = -0.38 / 4 = -0.095

    Multiply these values with forecasted (Y) Quarterly:

    Quarter _17 = -75.115 (1.1047)

    = -82.983

    Quarter _ 18 = (89.065) (0.06275)

    = -5.588

    Quarter _ 19 = (-103.015) (-0.022175)

    = 2.284

    Quarter _ 20 = (-116.965) (-0.095)

    = 11.11

    When we multiply these values we come to know that trend in the values againsame.
