Concerning the KM informal practices variable, as previous research showed, firms that encourage social interactions increase opportunities for knowledge diffusion over networks (Magnier- Watanabe & Senoo, 2008). As Nonaka (1994) stated, redundancy, that is, the sharing of extra information between individuals, promotes the sharing of tacit knowledge. In another way, extensive communication and incentives for socialization practices, which also consist of characteristics of the internal integration dimension, effectively impact KM informal practices.
