Perceptual mapping is useful because it makes easier for people to see and understand relationship when they are presented graphically, rather than when they are offered in columns of figures or in long verbal descriptions (Cahill, 1997, p.101). If we used perceptual mapping in our consultancy report it would, enable us to locate different brands in space, and, actually, see what Mortein stands for in relation to the competitors. Nevertheless, this technique has several drawbacks. Firstly, it compares only two, usually most important attributes, while other attributes ate neglected. Secondly, there is no way of representing benefit importance in perceptual maps because the attributes are invariably plotted as though they were of equal importance (Rossiter, 2005, p.70). In our particular case, for Mortein insect spray, if we employed perceptual mapping, we would probably obtain similar results to those from I-D-U benefit analysis. However, by using perceptual mapping techniques, we would have to spend considerably more time and effort on research and statistical analysis. Therefore, we believe that the I-D-U model favoured by Rossiter and Bellman (2005) is superior to perceptual mapping and other models of brand positioning.…
