Marketing research is a systematic process of analyzing data that involves conducting research to support marketing activities and the statistical interpretation of data into information. This information is then used by managers to plan marketing activities, gauge the nature of a firm's marketing environment and to attain information from suppliers. A distinction should be made between marketing research and market research. Market research involves gathering information about a particular target market. As an example, a firm may conduct research in a target market, after selecting a suitable market segment. In contrast, marketing research relates to all research conducted within marketing. Market research is a subset of marketing research.
Growth of a business is critical for business success. A firm may grow by developing the market or by developing new products. The Ansoff product and market growth matrix illustrates the two broad dimensions for achieving growth. The Ansoff matrix identifies four specific growth strategies: market penetration, product development, market development and diversification.
The product aspects of marketing deal with the specifications of the actual goods or services, and how it relates to the end-user's needs and wants. The product element consists of product design, new product innovation, branding, packaging, labeling. The scope of a product generally includes supporting elements such as warranties, guarantees, and support. Branding, a key aspect of the product management, refers to the various methods of communicating a brand identity for the product, brand, or company. 
One of the limitations of the 4Ps approach is its emphasis of an inside out-view.  An inside-out approach is the traditional planning approach where the organisation identifies its desired goals and objectives, which are often based around what has always been done. Marketing's task then becomes one of "selling" the organization's products and messages to the "outside" or external stakeholders. In contrast, an outside-in approach first seeks to understand the needs and wants of the consumer.
Market segmentation consists of taking the total heterogeneous market for a product and dividing it into several sub-markets or segments, each of which tends to be homogeneous in all significant aspects. The process is conducted for two main purposes: better allocation of a firm's finite resources and to better serve the more diversified tastes of contemporary consumers. A firm only possesses a certain amount of resources. Thus, it must make choices (and appreciate the related costs) in servicing specific groups of consumers. Moreover, with more diversity in the tastes of modern consumers, firms are noting the benefit of servicing a multiplicity of new markets.
