instructional literature to go alongside the product. This is generally done by supplying certain figures considered to be of consumer interest, such as horsepower output for a car, pixel count for a digital camera, or battery life for rechargeable electronics. (Hsee et al., 2009). This is done to simplify the product for the consumer, so that they can make their purchasing decision based on a few key attributes that fulfil their situational needs. (Barroso & Giarratana, 2013). The supplied figures may also form part of a larger operating manual or other form of instructional literature. Additionally, datasheets may provide similar information aimed at consumers with various levels of technical knowledge, such as products that relate to medical purposes. (Puttick, 1988). Product development literature Product development literature is a type of literature that is created and utilised during the constructing and designing of a product. This can begin when a product is in the stage of concept development (Krishnan & Ulrich, 1991). It is during this time that ideas regarding how the product will be configured and what life cycle it will have are decided upon by the manufacturer. The main focus of pre-development is to gather facts and to evaluate the potential success of the product before financially committing to the manufacturing process. (Adams & Hublikar, 2010). Literature that arises during this time includes planning material like blueprints as well as other transcribed forms of prototyping. As the product is in a developmental phase at this point in time, the material will tend to be prospective and plan for the challenges of future selling. Depending on the company, records of the literature may be made public or kept private to avoid their product being plagiarised. During and after the designing process of a product, various types of literature are used to refine the process of manufacturing, test the resulting product and to justify the market that the product will be entering into. (Brown & Eisenhardt, 1995). They also inform workers involved in the manufacturing process with technical knowledge as to how the product must be constructed. (Leonard-Barton, 1992). These types of literature may include mediums such as datasheets, correspondence within the supply chain and demographic research. Eventually these practices lead to marketing material and promotional literature that has been informed by the research undertaken during the development of the product. There is no guarantee that product development literature will be
