Tacit knowledge definitions tend to be extremely varied. Some argue that tacit knowledge is precisely that. Others feel that only time and effort prevent all tacit knowledge from eventually becoming articulated. For the purposes of our research “tacit knowledge”, in practice at least, encompasses a medium ground, being comprised of articulable and inarticulable subsets. Along the lines of Weber (1997), we have formalised a meaning for this “tacit knowledge” and for comparison have completed a content analysis of the literature to determine what other researchers understand “tacit knowledge” to mean.
