Therefore, most users within the related anizations can be identified in advance, and some of the business partner users can bereached prior to the early stage of system development. But this type of user growth rate is often limited since business partners are corporations, which, obviously, cannot increase in number as rapidly as can its consumers. One of the most important user requirements is “information” gathering and sharing。 and (4) the acquisition of mercial goods (Rodgers and Sheldon, 2021). Exploration is related with play, and some researchers contend that playfulness has a significant effect on usage (Atkinson and Kydd, 1997). Therefore, this study adopts playfulness or entertainment as a dimension for WIS use. As a starting point for discussion, the user characteristics and their acpanied requirements in different WIS applications are listed below. As shown in Table I, amajority of users in intras are employees in an anization。 (2) munication。 Kaonkar and Wolin, 1999。 (3) a sample of users may not represent the entire user population. Accordingly, there is great value in assessing the requirement of “typical” or “influential” online users to get an accurate snapshot of the needs of the entire user Population. The present study classifies WIS usage dimensions by first addressing the two major questions of WIS users – whether or not users are “too heterogeneous” or are “too many” – and subsequently assesses the “influential” key users according to various WIS usage dimensions. Key users may have different meanings according to their specific contexts. For example, on a mercial web site, key users may be very important customers, such as those who contribute most of the revenues of the corporation. The key users are defined in this study as influential users who may influence other users in significant WIS usage. For example, the key users may influence others in purchasing decisions, in their methods of information seeking or getting advice, in the establishment and maintenance of online interpersonal relationship with oneanother, or in the way that they entertain themselves online. The WIS usage dimensions Compared with traditional IS users, WIS users are more diverse and heterogeneous。 and (3) a small number of users can represent the entire user population. However, these fundamental assumptions have been questioned because: (1) some WIS users cannot be targeted appropriately before the early stage of system development。 Sampson, 1998). The basic assumptions are that: (1) users can be identified at the early stage of system development。 Pressman, 1998). Wang and Head (2021), for example, first made a contrast between traditional IS users and WIS users and then proposed a conceptual framework for etailing development. While it is beyond the scope and purpose of the present study to solve the controversy between the difference of traditional software development and WIS development, it will hopefully elucidate some of the differences between user requirements for traditional software and WIS and Head (2021) presented a detailed parison between traditional IS users and WIS users. While acknowledging that all the above differences do exist, the most important differences between IS and WIS users were shown to be: (1) unknown before the early stage of system development or even unknown before system operation； (2) too heterogeneous； (3) perhaps too many users on the WIS. If users cannot be identified prior
