Consequently, we conclude with a recommendation and the significance of proposed framework as well as future directions for research and practice. E-commerce quality modelsMuch discussion in the literature has taken the view of online consumers when evaluating the quality of electronic commerce Websites (Balfagih et al, 2008).In this regard, the online consumers may evaluate the quality of the product purchased, service quality of provider, electronic commerce systems as product quality and quality of the Human-Computer Interaction (HCI) design.The concern of this section, however, is on the electronic commerce systems as product quality and quality of the Human-Computer Interaction (HCI) design that make up quality of electronic commerce Websites.In design, the term usability is commonly used.Usability concerns with ease of use and ease of learning.Bad usability could turn-off users or customers.It has been cited that the interface design is crucial because the user will experience usability first before deciding to conduct a transaction such as buying the product (Nielsen, 1999;Nielsen, 1993).Usability is also a critical factor for a user to re-visit or to recommend an electronic commerce Website to another customer; which is critical to the overall performance of electronic commerce.Usability may also influence users in their decision to buy the product.Several elements are important for consideration in the design process of electronic commerce Websites: selection of design features, visualization of content, navigation and control, accessibility and attractiveness.Besides, attractiveness has been cited as critical in ensuring users are attracted to a particular Website and continue to transact at the Web site (Sutcliffe, 2001;Sutcliffe, 2002).Recognizing the importance of electronic commerce systems as product quality and quality of design, several researchers grouped critical elements that make up quality of electronic commerce design into a framework or a model.In the ensuing discussion, we will discuss Rayport and Jaworski 7Cs Framework, DeLone and McLean Electronic Commerce Model, The ISO 9126 Quality Model, WebQual 4.0 Model, Palmer's Model and Stefani and Xenos Quality Model.Rayport and Jaworski (2001, pp.115-117) developed the 7Cs framework in defining the quality of electronic commerce Website design from the online consumers' perspective. Rayport and Jaworski 7Cs Framework Context -The context of an electronic commerce Website defines its aesthetic and functional look-and-feel which encompasses interesting graphics, colors, design features, goals and ease of navigation. Content -The content in an electronic commerce Website defines all digital subject matter including text, video, audio and graphics to convey the message of the site. Community -This aspect refers to the communication that occurs between two users such as through e-mails or chat.This element, however, does not cover a user's experience when interacting with the Website. Customization -Customization refers to the electronic commerce Website's ability to tailor itself or to be tailored by each user such that a user is provided with a www.intechopen.
