A concern relevant to the viability of a Knowledge Management System (KMS) implementation may well be: at what point is there adequate information packets and links among them to achieve value to the user? A closely associated statement may wonder if the size of a company or the number of knowledge workers in the company may or may not be sufficient to generate enough links. This paper uses a realist research approach to study how the mechanism of adding links among stored packets of information in a KMS, impacts the outcome of user acceptance. The paper’s context will specifically analyze KMS in Small to Mid-sized Enterprises (SMEs) and attempt to determine whether there is a measurable point (tipping point) where the extent of links is such that the user community will value and accept the system.
