“…Given the pluralistic nature of organizations (Denis, Langley, & Rouleau, 2007;Smith, Lewis, Jarzabkowski, & Langley, 2017b), dual or even multiple strategies that have different legitimacy appeals to different stakeholders are likely to be increasingly pertinent, and to create extensive challenges for organizations (Comeau-Vallée, Denis, Normandin, & Therrien, 2017;Denis, Langley & Sergi, 2012). While our study examined a new SUST, there are likely to be many other contexts in which one or more new strategies need to be co-enacted with an existing strategy, such as digitalization strategies (e.g., Ivang, Rask, & Hinson, 2009), online strategies (e.g., Edelman, 2007), or regulatory strategies (e.g., Jarzabkowski et al, 2013;Marcus & Geffen, 1998), giving rise to legitimacy struggles during their implementation. Thus, studying how multiple, potentially competing strategies are constructed as (il)legitimate relative to each other during strategy implementation provides a fruitful avenue for future research.…”
