We thank the focal article authors for bringing the topic of Lean management to the field of industrial and organizational (I-O) psychology. Much like a number of other major areas of business practice, Lean has yet to be studied by I-O psychologists despite its prevalent use in the business world. The lack of research into Lean management practices and its impact on employees exemplifies the challenges that face the science and practice of I-O psychology. Recent calls to expand the focus (Ones, Kaiser, Chamorro-Premuzic, & Svensson, 2017) and methodological tools (Cucina & McDaniel, 2016; Spector, 2017) of I-O psychology highlight the increasing narrowness of our research and practice. These calls echo the concerns of earlier researchers (Gasser, Butler, Waddilove, & Tan, 2004; Ryan, 2003) about I-O psychology's trajectory. In this response, the authors would like to offer a new framework to expand the research focus of I-O psychology that would include a greater role of I-O in analyzing business practices such as Lean management. We see a potentially important role of I-O psychologists as "debunkers" and testers of business practice, echoing Gasser et al. (2004), using our methodological and statistical competence to help businesses toward research supported practices. In such a role we build from major elements of our current field identity rather than lose that identity attempting to mirror other fields (Ryan & Ford, 2010). We cannot be these "debunkers" however, if we only test theories from our own field and not the practices actually being used in organizations. The claims of a purveyor of a "fad" practice are easier to swallow when there is no existing research against that claim. This commentary will begin by outlining the concerns with I-O psychology's increasingly narrow focus and then suggest how the field could increase its real-world impact by examining vigorously and empirically business practice "fads" like Lean. A common theme emerges across the criticisms of I-O psychology's narrowing focus of research and limited applicability to practice has been one of identity (Lefkowitz, 2010; Ryan, 2003) and the lack of innovation and discovery of new concepts (Ones et al., 2017; Spector, 2017). However, we would argue that this narrowness of focus has highlighted the significant need to examine the identity of I-O psychology. In order to expand the identity of I-O psychology and to address the calls for innovation to reinvigorate the field, I-O psychologists must look to how we define ourselves. If we do not make such an examination, we may cling to outdated meanings, drift away from our mission, or even lose our bearing entirely engaging in hyperadaptation and becoming just a mirror image of external stakeholder values (Hatch & Schultz, 2002; Ryan & Ford, 2010). It is better to reflect and choose an appropriate role rather than have a different role forced upon the field or drift into irrelevancy to the larger business community. A common definition of I-O psychology is the application of psychological p...
