Knowledge for customers can be the information and expertise about products and services developed and provided by companies. Such type of knowledge can be offered by firms in terms of pure knowledge service (e.g., Google and Thomson Reuters), or in terms of knowledge service integrated with products. Firms can provide related knowledge to their customers to help them better use the product/service, or to facilitate customers involvement in knowledge interaction. In this way, firms can improve customers use experience and retain their existing customers (Desouza & Awazu, 2004). In addition, being supplied with detailed and comprehensive comparative information on different options, potential buyers can quickly make well-informed decisions through a substantially simplified and accelerated buying process with reduced bargain cost (Amit & Zott, 2001). In all cases, customers will benefit from those integrated and/or specialized knowledge that companies purposively design for them (Smith & McKeen, 2005).
