Considering the effect of the M.A.P.S. treatment no definite conclusions can be drawn from the results. In the case of Dixie and Miller Lite, change in location of the brands did increase sales. This however defeats the object of the exercise as the change in position of Dixie Light has decreased sales by 1% whereas Miller Lite, the main competitor, noticed an increase in sales. This shows that the M.A.P.S. treatment did not produce its desired outcome.
Dixie sales dramatically increased, whereas sales of Miller decreased showing brand position may have an effect. However, in a study of this nature you cannot rely on one factor alone to determine consumer decisions. A more reliable and valid outcome could be achieved by including tests for other factors in the research design, for example timeframe, weather, taste, advertising and promotions.
How could the marketing Design be improved? Taking these factors combined with the disadvantages into consideration improvements could be made to the M.A.P.S. plan to provide more interpretable results. Firstly the problems of the original experiment have to be addressed. The most important of these is timescale. Treatment one was conducted in the first two weeks of April and the second in the last two

To increase the accuracy of the results treatment one and two should be conducted at the same time in controlled environments. Therefore both treatments will be subject to any changes in external factors that may occur making the results more comparable. The experiment would therefore have to be held in two stores of similar size with the same set up in terms of catchment area, size, shelf space and turnover, for example two supermarkets within a chain could be used. Also, by using a supermarket the number of sales and customers will be increased as people are more likely to make such purchases when conducting their weekly shop.
By placing the brands in the same environments, this indicates that any changes to sales will be due to the factors under experiment rather than any others. Two groups will be required; a control group which consists of the original style of shelf positioning and an experimental group consisting of the M.A.P.S style. This experimental design can be represented symbolically as shown below. Experimental Group: O1 X O2 (O = observation) Control Group: O3 O4 (X = treatment) The effect of the treatment can be estimated by (O2 – O1) – (O4 – O3). This will show the effect repositioning has on beer sales, with external factors constant for both groups making it a fairer test than the M.A.P.S plan. The effects of the extraneous factors can be illustrated by (O4 – O3 ), (McDaniel and Gates, 2002).
As mentioned before Dixie Light experienced the lowest sales among all brands whether its shelf position changed or not. It is therefore necessary to find more detailed information about their products. By conducting a general questionnaire, non – specific to the ‘Dixie’ brand for security reasons, it could enable the researcher and company to identify other factors that may need to be tested, for example, price, awareness of the product. Ideally the questionnaire could be conducted on the shop floor in the beer aisle to ensure the correct audience is targeted. It will have to remain short to keep customer attention and be in multiple choice format making it quick and easy to answer.
In addition to this, if the Dixie Brewing Company have their own website, they could incorporate a more personalised questionnaire to discover customer views on their products, particularly with reference to taste of the products. Alternative products could be produced and taste tests carried out, however this would be an expensive process so pretests and prior research will have to be carried out to sum up cost benefit analysis.
From the results of the questionnaires, it is possible to determine what influences consumer decisions, therefore some changes can be made to not only the research design but also the product. The alternative research design outlined above will provide more reliable results, therefore making the experiment more internally valid, because as far as possible, other influencing factors have been removed.
