“…Our findings hold implications for understanding how management may influence project behaviors and problem-solving: Firms that need to concentrate on more incremental problem-solving efforts (e.g., because a sufficient number of attractive problems have already been defined) should create environments in which interaction is undertaken mainly via artifacts. On the other hand, if firms seek to generate new problems (e.g., new strategic opportunities), they should create environments in which open-ended, verbal conversation is relatively more important than artifact-based communication.We address communication-based antecedents of whether community members launch new projects (set up new problems) or join existing projects (solve subproblems defined by others or define subproblems within an overall problem structure defined by others), framing our discussion in terms of the "problem-solving perspective" (e.g., Baer, Dirks, and Nickerson, 2013;Heiman, Nickerson, and Zenger, 2009;Macher, 2006;Macher and Boerner, 2012;Nickerson and Zenger, 2004). We specifically argue that an individual's project-behavior (i.e., launching or joining) is predicted by the mode of communication (Guetzkow and Simon, 1955;Orlikowski and Yates, 1994;Zmud, Lind, and Young, 1990) and the associated artifacts (or absence thereof) that characterize the context of interaction around the focal individual.…”
