“…Each concept is defined, the studies' context explained and any important facet of the treatment of ambiguity noted (see Table 1). The OM literature has treated ambiguity as performance ambiguity (Boloori et al, 2020;Cachon and Lariveiere, 2016;Gray and Handley, 2015;Wacker et al, 2016), information ambiguity (Peng et al, 2008), causal ambiguity (Hunt and Davis, 2008;Lawson and Potter, 2012), extreme ambiguity (Silvestre et al, 2015), role ambiguity (Dong et al, 2016), relational/contractual ambiguity (Jia et al, 2016;Kim and Choi, 2015;Steinbach et al, 2018), and processing time ambiguity (Cheon et al, 2017).…”
