PERCEPTUAL MAPPING

APPLICATION IN MARKET RESEARCH

Perceptual Maps

•To gain competitive advantage, a firm must correctly position itself, its products, or services against competitive offerings.

•Need to develop a “Mental Map” of how our product is perceived by consumers relative to the different competing products in the marketplace.

•Linking Segmentation and Positioning.

•Techniques that help us to construct such mental or Perceptual Maps are called Multidimensional Scaling and Factor Analysis.

What is a Perceptual Map

A perceptual map is a visual representation of how target customers view the competing alternatives in a Euclidean space which represents the market.

The map has the following characteristics:•Pair-wise distances between product alternatives directly indicate how close or far apart the products are in the minds of customers•A vector on the map indicates both magnitude and direction in the Euclidean space. Vectors are usually used to geometrically denote attributes of the perceptual maps•The axes of the map are a special set of vectors suggesting the underlying dimensions that best characterize how customers differentiate between alternatives

• Specify the "Relevant" Objects or Products.

• Relevance means that the set of products chosen must be the set of competitive products that are relevant for managerial decision-making.

• Two possible methodologies to collect information on consumers perception of products: – Method 1: Attribute based method (Factor Analysis).

– Method 2: Similarity-Based method (Multi-Dimensional Scaling)

Perceptual Mapping Process

Method 1: Attribute Rating MethodExample: Evaluation of a New Laptop concept.

•Select a set of laptop computers of interest to be the target group including the new concept…(say 4 products)

•Decide on the set of relevant attributes on which to capture consumer perceptions (6 attributes)

•Prior quantitative or qualitative research that elicits important attributes for the target consumers.

•Ensure that consumers are familiar with the laptops that are to be evaluated (e.g., through video presentation, or actual prototypes)

•Respondents (target customers) evaluate / rank or rate products.

Consumers

Data Matrix Factor Analysis Perceptual map

Submit data to factor analysis

Interpret the underlying key dimensions (factors) using the directions of the individual attributes

Explore the implications of how consumers’ view the competing products

Factor Analysis: Key Concepts

• It is difficult to get a clear picture of the market when dealing with so many attributes and products.

• All the data/dimensions might not be necessary to capture consumer perceptions. Why?

• Highly correlated attributes– Create linear combination of the measures to get a single new

dimension of the original attributes.

• Take out attributes on which all computers are rated about the same.

• Factor analysis output: – Say 70% of the information contained in the original attributes can

be represented by creating just 2 new dimensions. These dimensions are called factors.

– Analysis done using commercial software SPSS or SAS

The six attributes were measured on semantic differential scales: 1) Slow–Fast operation, 2) Plain–Elegant,

3) Easy–Difficult setup, 4) Poor–Excellent value, 5) Light–Heavy, and 6) Common–Distinctive.

• The arrow indicates the direction in which that attribute is increasing.

• Length of the line from the origin to the arrow is an indicator of the variance of that attribute explained by the 2D map. The longer this line, the greater is the importance of that attribute in capturing variance.

• Attribute that are both relatively important (i.e., long vector) and close to the horizontal (vertical) axis help interpret the meaning of axis.

• To represent a laptop on each attribute, draw an imaginary perpendicular line from the location of the laptop onto that attribute. (These are shown by dashed lines on the map).

• What practical uses can you now put this map to at this stage?

Guidelines for Interpreting Perceptual Maps (Laptop)

• Researcher should be able to clearly conceptualize the attributes

• No perception gap between intended and actual perception of the attributes.

• Works well for hard or functional attributes, (price, product features).

Limitations

• Customer Analysis and Competitive Analysis– Understand the competitive market structure as perceived by

customers.• Position relative to competition• Select the set of competitors to compete against

– Represent customers’ perceptions in a manner that aids communication and discussion within the organization

• Product– Perceptions of a new product concept in the context of existing

brands in the market– Finding the “gap” in the market to position the product.

Uses of Perceptual Maps

• Perceptual maps are about “How our product is perceived by consumers relative to competition?”– Link Segmentation and Positioning

• Segmentation, Positioning and Perceptual mapping involve careful and sophisticated quantitative analysis and not vague managerial intuition.

• Two important methods to develop perceptual maps– Attribute rating

– Similarity rating
