The purpose of this paper is a first-hand study of lean improvement programs that has led the authors to distinguish two different forms of learning intent: exclusive learning versus inclusive learning. These two forms of learning reflect two different attitudes to learning. With exclusive learning, the executives expect to learn by themselves and then apply this learning to the organization – and then reap the benefits. With inclusive learning, the executives intend to learn with others and from their own learning efforts – and share the benefits. The authors argue that these learning attitudes account for a large part of the difference between the success and failure of lean initiatives.

The paper is based on over 25 years of research studying Toyota – where the term “lean” was first used to describe their particular way of working – together with working with hundreds of other organizations around the world across all sectors.

To implement a lean strategy that brings long-term, effective change requires senior executives to start with their own personal learning journey and to create an inclusive learning culture within their organization.

The paper provides a succinct summary of how a different mindset is required from senior executives if they are to create and implement a truly lean strategy for their organization. Their behaviors enable or inhibit what the authors describe as an “inclusive” learning environment which will create and maintain a sustainable shift to a lean culture.

This study describes how two organisations transitioned to teaching Lean online during and post Covid-19. This study aims to establish how Lean teaching and training can be designed and delivered effectively online without adverse effects on the student’s learning experience of Lean concepts.

A case study approach was used to review the design, application and results of the transition to online Lean teaching and training. Qualitative and quantitative methods were deployed to assess the results.

Online Lean learning and application were assured via the design of practical problem-based teaching environments, aided by using the virtual classroom as an obeya room and as a kaizen environment where students worked in teams. Students were enabled to learn and apply Lean tools practically and reflect on their learnings.

This study demonstrates that effective online design can ensure. Lean methods are understood without affecting the student's learning, classroom experience and grasp of concepts.

To the best of the author’s knowledge, this is one of the first studies on implementing Lean training and education online during COVID-19 under the lens of both a training provider and university education viewpoint. The changes validated best practices for virtual Lean education and training in the organisations under study, maintained post-COVID.

The purpose of this paper is to present and discuss two different learning approaches to lean through a sensemaking lens.

This is comparative case study within one organisation, and a qualitative analysis of interview data, participative observations and documents.

Although this study found that both practices promoted lean thinking in the organisation, the “calculating lean approach” has an approach oriented towards one profession, namely, medical doctors, whereas “doing lean” has a more multi-professional-oriented approach.

This research enriches the literature on workplace learning in relation to lean, seen from a practice-based perspective. The authors argue that “The calculating lean approach” and its use of data presentations is best suited to persuade the powerful doctors to join, when working with small improvements. “The doing lean approach,” on the contrary, is more suited to promote more comprehensive changes from the bottom up that require a deeper understanding of lean among all the professions involved.

The lack of knowledge has hindered the successful implementation of lean in the construction industry. This has alarmed the need for lean learning practices. Out of numerous models, the learning-to-learn sand cone model received a wider acknowledgment for learning practices. Thus, this study aims to propose a learning-to-learn sand cone model integrated lean learning framework for the construction industry.

The research adopted an interpretivism stance. A qualitative research approach was adopted for the study. Consequently, fifteen (15) semi-structured interviews and document reviews were carried out to collect data in three (3) cases selected through purposive sampling. Code-based content analysis was used to analyse the data.

Fifty-two (52) sub-activities pertaining to nine lean learners at each stage of the lean learning procedure were identified. The most significant practices in the lean learning procedure to continuously improve lean learning in the organisation were maintaining records, providing a performance update to senior management and preparing and distributing several hierarchical manuals for all levels of staff to aid in the implementation of lean approaches.

The findings of the research can be aided to successfully implement lean by following the identified sub-activities via various parties within the organisation. The proposed lean learning framework opens several research areas on lean learning in the construction industry. This is the first research to uncover a lean learning framework in the construction industry rather than at the educational institute level.

The purpose of this study is to empirically test how problem-solving lean practices, along with leaders as learning facilitators in an action learning approach, can be transferred from a production context to a knowledge work context for the purpose of becoming a learning organization while enhancing performance. This is important to study because many organizations struggle to enhance efficiency in the short term while still trying to be long-term learning oriented (i.e. learning organization development).

The authors draw on theory on learning interventions to show how lean practices for problem-solving can foster learning and help an organization to become adaptive. This study’s subject is a non-production department of 100 employees at the LEGO corporation. The authors applied survey results from a natural experiment lasting 18 months between a pre-measurement survey and a post-measurement survey. The results were compared to a control department of 50 employees who were not exposed to the lean practices intervention. The authors’ focus was on the individual level as individuals have different perceptions of lean practices, performance, and learning.

Using repeated-measures tests, difference-in-difference regressions analyses, and structural equation models, the authors find that a package of contemporary lean practices for problem-solving, along with leaders who function as learning facilitators, significantly improved learning organization dimensions while also enhancing efficiency and quality and that learning organizations positively mediate the relationship between the lean intervention and quality-related performance, while efficiency is directly affected by the lean interventions. Data from LEGO's key performance indicators (KPIs), benefit trackers, on-site observations and more than 40 interviews with managers provided results that were consistent with the survey data. A detailed description of the lean practices implemented is provided to inspire future implementations in non-operations environments and to assist educators.

The authors contribute to the learning literature by showing that a learning-to-learn approach to lean management can serve as an active and deliberate intervention in helping an organization becoming a learning organization as perceived by the individual organizational members. The authors also add to the lean literature by showing how a learning approach to lean, as used by LEGO, can positively affect short-term efficiency and quality and create a foundation for a longer-term competitive advantage (i.e. a learning organization) in a non-production context. By contrast, most of the lean literature streams treat efficiency separately from a learning organization and mainly examine lean in a production context.

The extant literature shows three research streams on lean, learning, and performance. The authors built on these streams by trying to emphasize both learning and efficiency. Prior research has not empirically tested whether and how the application of problem-solving lean practices combined with leaders as learning facilitators helps to create a comprehensive learning organization while enhancing performance in a non-production context.

Frontline teams are at the centre of lean transformations, but the teams also transform as they implement lean. This study examines these changes and seeks to understand how lean relates to team psychological safety and learning.

This research setting is the Romanian division of a leading European energy company. The authors collected team-level audit and survey data, which the authors used to test the effect of lean implementation on team psychological safety and learning. The authors’ team-level data are complemented with qualitative interviews conducted with team members and headquarters leaders.

The results of the regression analyses show that leanness is positively associated with team psychological safety, which is in turn positively associated with learning. Thus, this research provides evidence that leanness – mediated by team psychological safety – increases team learning.

Lean changes team dynamics and learning positively by ensuring and promoting an emotionally sound work environment with clear team structures, an appropriate level of autonomy, and strong leadership.

This paper contributes evidence of important psychological mechanisms that characterise team-level lean implementation. Particularly, the authors highlight how team psychological safety mediates the relationship between leanness and team learning.

The purpose of this paper is to present a methodology to assess the experiential learning processes of learning lean in an innovative learning environment: the lean model factories.

A literature review on learning and lean management literatures was carried out to design the methodology. Then, a case study methodology was used to test the framework.

The methodology permitted to asses learning processes and course contents of educational dynamics carried out in model factories and to theoretically ground such learning processes. The test showed that learning lean management is supported through a complete coverage of the eight phases of the learning path.

The methodology contributes to the literatures of lean management and experiential learning, proposing a methodology of assessment. Part of the framework could also be applied to other disciplines.

The methodology could be used for two purposes: to design training courses or to assess existing experiential learning courses.

Due to its intrinsic complexity, learning literature presents few practical framework or tools. Among them, none have provided practical and theoretical-based advice on how to use experiential learning precepts to teach lean management.

This paper investigates developing a learning-to-learn capability as a critical success factor for sustainable lean transformation.

This research design is guided by our research question: how can suppliers learn to learn as part of a buyer-led collaborative lean transformation? The authors adopt action learning research to generate actionable knowledge from a lean supplier development initiative over a three-year period.

Drawing on emergent insights from the initiative, the authors find that developing a learning-to-learn capability is a core and critical success factor for lean transformation. The authors also find that network action learning has a significant enabling role in buyer-led collaborative lean transformations.

The authors contribute to lean theory and practice by making the distinction between learning about and implementing lean best practices and adopting a learning-to-learn perspective to build organisational capabilities, consistent with lean thinking and practice. Further, the authors contribute to methodology, adopting action learning research to explore learning-to-learn as a critical success factor for sustainable lean transformation.

The purpose of this paper is to examine the digitalization of operational processes and activities in lean manufacturing firms and explore the associated learning implications through the lens of cumulative capability theory.

Adopting a multiple-case design, we examine four cases of digitalization initiatives within lean manufacturing firms. We collected data through semi-structured interviews and direct observations during site visits.

The study uncovers the development of learning capabilities as a result of integrating lean and digitalization. We find that digitalization in lean manufacturing firms contributes to the development of both routinized and evolutionary learning capabilities in a cumulative fashion.

The study adds nuance to the limited theoretical understanding of the integration of lean and digitalization by showing how it cumulatively develops the learning capabilities of lean manufacturing firms. As such, the study supports the robustness of cumulative capability theory. We further contribute to research by offering empirical support for the cumulative nature of learning.

Being acquainted with both lean and action learning in theory and in practice, this study finds that the theoretical complementarity of these two research streams has traditionally been underexploited. In this conceptual paper, this study aims to advance the theoretical understanding of lean by exploring the complementarity of lean thinking and action learning leading to a proposed integrated theory of these two research streams. Target audience is the operations management research community.

By deliberately adopting a process of theorising, this paper explores, reflects upon and combines individual experiences of researching, teaching and engaging in lean and action learning as operations management scholars.

Having taken a gemba walk through the literature and practices of lean and action learning, this study views and notices a systematic and complementary relationship between the two domains. The overlapping theoretical and practical complementarities of lean and action learning suggest that these two research streams are ripe for synthesis into an integrated theory. This finding provides an opportunity to (1) progress towards an integrative design of interventions leading to more sustainable lean system adoptions and (2) add new depth to our theoretical explanation of the success and failures of lean system adoptions.

This paper contributes an original integrated theory perspective on lean and action learning.
