“…Themes Future research proposals of LM Extent of Lean use/ implementation Determine the extent to which Lean is in use in each country (Moyano-Fuentes and Sacristan-Diaz, 2012); the status of Lean implementation among European countries (Dora et al, 2013); Lean maturity in several countries (Marodin et al, 2016); the relative importance of individual improvement routines at various degrees of Lean implementation in different countries (Knol et al, 2019); whether the original TPS is implementable as a whole in the traditional European manufacturing context (Chiarini and Brunetti, 2019); the maturity level of Lean practices: Strategic planning, quality at source, processes and tools, problem-solving, people, supplier integration, continuous improvement, customer focus in Brazilian states (Bento amd Tontini, 2019) Factors influencing Lean Study the key determinants (Trigger factors, success factors, control factors) of Lean in geographical contexts other than Spain (Martinez-Jurado and Moyano-Fuentes, 2014); the contribution of external factors such as socioeconomic, political (like government regulation related to public safety) and environmental factors to successful Lean (Panwar et al, 2015a, b); the workplace factors affecting Lean performance in a country (Vlachos and Siachou, 2018); the critical success factors in LM in different countries (Knol et al, 2018), how firms work within national Institutions during their LM journey (Friela and Villechenon, 2018); the dynamic fit between LM and the adopting organisation and how this fit is influenced by technical, cultural, and political factors (Antony et al, 2021), the influence of process innovation on Lean in certain regions (Moldner et al, 2020), factors such as government policies, cultural differences and organisational structure of several countries (including those countries with a large population) that affect the relationship amongst enablers of LM (Prasad et al, 2021), the impact of policy, funding and legislation on Lean and sustainability oriented innovation, in different regions and economies…”
