2. Literature Review
Recent transformations in public sector education and professional development have been marked by intense debates around institutional innovation, sustainable governance, and digital adaptation, especially in countries characterized by significant social, territorial, and organizational diversity such as Brazil. The global literature increasingly recognizes that, for public management to effectively contribute to sustainable development and the improvement of collective well-being, it must be grounded in capacity-building strategies that move beyond generic, prescriptive, or fragmented models (Bruschi & Forcellini, 2019; Martha et al., 2021; Kluza et al., 2021). In this context, two interconnected paradigms—Lean management and micro-credentialing—have emerged as central themes in contemporary academic and practical discussions. Both are now considered pivotal for the public sector’s ability to respond to the dynamic demands of environmental stewardship, process efficiency, transparency, and citizen-centered service delivery.
The roots of Lean thinking are widely acknowledged in the literature as emerging from Japanese industrial practices, most notably those of Toyota, and subsequently being adapted to a broad array of sectors, including services and public administration (Womack & Jones, 1997; Teeuwen, 2011). Lean is fundamentally oriented toward eliminating waste, streamlining value flows, and engaging all organizational actors in the relentless pursuit of improvement (Bruschi & Forcellini, 2019; Kamaruddin & Hanefah, 2023). In the public sector, these principles have been reframed to account for the specificity of bureaucratic cultures, legal frameworks, and the political nature of state action. Studies in Brazil and internationally have identified value stream mapping, process standardization, and the active involvement of employees in diagnostic and solution-generating processes as core aspects of successful Lean implementation (Brunetti et al., 2020; Diniz & Campos, 2020; Klein et al., 2022; Hegedić et al., 2024).
Despite its origins in manufacturing, Lean’s central focus on value creation, as perceived by service users, makes it especially relevant for the public sector, where the final “customer” is the citizen or society itself. Literature has shown that, when Lean is adapted for governmental settings, it supports the development of a culture that values data-driven decision making, participatory management, and incremental change anchored in empirical evidence (Radnor & Walley, 2008; Lukrafka, 2018). Lean interventions in Brazilian municipalities, for example, have been linked to reductions in procedural times, error rates, and costs, as well as improvements in service quality and internal communication (Bruschi & Forcellini, 2019; Klein et al., 2022). International research reinforces that the sustainability of Lean in the public sector depends on leadership commitment, context-sensitive adaptation, the creation of feedback mechanisms, and the engagement of staff at all hierarchical levels (Johnston & Fenwick, 2024; Kamaruddin & Hanefah, 2023; Brunetti et al., 2020).
Concurrently, the literature on professional development and adult learning in public administration has increasingly emphasized the inadequacy of traditional, one-size-fits-all training programs (Grech et al., 2021; Martha et al., 2021; Morte-Nadal & Esteban-Navarro, 2022). Classic models, often delivered through centralized and prescriptive modalities, have struggled to accommodate the growing complexity of public functions, the accelerating pace of regulatory and technological change, and the need for ongoing upskilling. As a result, public servants frequently encounter a disconnect between the content of formal training and the real demands of their work environments, with consequences for both organizational performance and professional motivation (Klein et al., 2022; Lukrafka, 2018; Grech et al., 2021).
This backdrop has catalyzed the rise of micro-credentialing, which represents a paradigm shift in how learning, competence, and professional progression are conceptualized and recognized in the public sector (Selvaratnam & Sankey, 2021; Martha et al., 2021; Moldovan et al., 2024). Micro-credentials are defined as short, targeted certifications—often digital—that formally acknowledge the mastery of specific skills, knowledge areas, or behavioral competencies. Their modular nature makes them highly adaptable to organizational and individual needs, supporting the construction of personalized learning trajectories and enabling real-time, evidence-based validation of capabilities (Mnisi, 2023; Grech et al., 2021). They also offer flexibility for public servants in geographically dispersed or resource-constrained environments, as content can be delivered asynchronously and adapted to local priorities (Tan et al., 2023; Morte-Nadal & Esteban-Navarro, 2022).
Multiple studies, including those conducted in Brazil, Spain, and Australia, highlight the benefits of micro-credentials for democratizing access to professional development and enabling just-in-time upskilling (Martha et al., 2021; Selvaratnam & Sankey, 2021; Morte-Nadal & Esteban-Navarro, 2022). They also allow organizations to respond more effectively to changes in policy, technology, or citizen expectations by updating modules or content as new needs arise (Tan et al., 2023). Nevertheless, the literature acknowledges several persistent challenges, such as the lack of formal integration of micro-credentials into public sector career frameworks, the skepticism of traditional managers, digital divide issues, and the need for robust digital infrastructure (Waithira et al., 2024; Klein et al., 2022; Grech et al., 2021).
The intersection between Lean thinking and micro-credentialing is a promising but under-explored area in public sector studies (Bruschi & Forcellini, 2019; Martha et al., 2021; Klein et al., 2022; Waithira et al., 2024). There is growing recognition that combining these two paradigms can yield greater impact than isolated interventions, both in terms of individual learning outcomes and broader organizational transformation. Lean tools provide the analytic and procedural foundation for identifying competency gaps, streamlining work processes, and making visible the value generated at each step of service delivery (Brunetti et al., 2020; Hegedić et al., 2024). Micro-credentials, in turn, translate these insights into modular training interventions, enabling organizations to certify mastery in specific processes or tools and to reward adaptive behavior and innovation (Martha et al., 2021; Mnisi, 2023).
This integration is reflected in recent empirical research from Brazil, which shows that capacity-building programs aligned with Lean mapping and modular certification can significantly improve completion rates, reduce administrative errors, and foster communities of practice within public organizations (Martha et al., 2021; Klein et al., 2022; Waithira et al., 2024). Participatory instructional design—wherein public servants themselves help co-create the content and structure of learning modules—has proven particularly effective in strengthening engagement, relevance, and learning transfer (Bruschi & Forcellini, 2019; Martha et al., 2021). Furthermore, the creation of shared digital repositories of micro-credentials and best practices supports the dissemination of innovation and the institutionalization of successful routines across diverse organizational units and territories (Tan et al., 2023; Moldovan et al., 2024).
International comparative studies reinforce these findings. For example, research on government agencies in Italy, Spain, Kenya, and Indonesia suggests that integrating Lean and modular learning supports the formation of organizational cultures that value continuous improvement, peer learning, and results-based management (Brunetti et al., 2020; Morte-Nadal & Esteban-Navarro, 2022; Waithira et al., 2024; Wiharja et al., 2024). In Spain, modular learning was credited with improving knowledge transfer and alignment between training and institutional goals, while Lean adoption facilitated the removal of procedural bottlenecks (Morte-Nadal & Esteban-Navarro, 2022). Studies in Italy and Brazil highlight that participatory approaches and iterative evaluation cycles are essential for overcoming cultural and structural resistance to change (Bruschi & Forcellini, 2019; Brunetti et al., 2020).
Nonetheless, the literature remains cautious regarding the risks of superficial adoption or “toolbox” approaches to Lean and micro-credentials (Kamaruddin & Hanefah, 2023; Klein et al., 2022; Lukrafka, 2018). Scholars warn that meaningful transformation requires not only technical solutions, but also changes in mindsets, incentive structures, and institutional values (Grech et al., 2021; Martha et al., 2021). There is consensus that leadership commitment, integrated digital infrastructure, and the alignment of professional development with performance evaluation systems are preconditions for sustainable success (Radnor & Walley, 2008; Johnston & Fenwick, 2024).
Within the Brazilian context, the implementation of Lean and modular capacity-building models has shown particular relevance in the management of Terms of Decentralized Execution (TEDs) for agricultural and environmental policy (Kluza et al., 2021; Klein et al., 2022). Persistent challenges in this domain—such as procedural delays, errors in documentation, and insufficient intergovernmental coordination—have been linked to a lack of standardization, inadequate professional development, and limited feedback loops (Bruschi & Forcellini, 2019; Klein et al., 2022). The literature documents positive outcomes when Lean mapping and micro-credential-based training are used to align competencies with the operational realities of public service delivery, including reductions in error rates and the creation of collaborative learning environments (Martha et al., 2021; Klein et al., 2022).
The literature further discusses the role of digital transformation in enabling and scaling these innovations (Tan et al., 2023; Grech et al., 2021). The adoption of cloud-based platforms, digital badges, and analytics for tracking learning progress have enabled not only greater inclusion of staff from remote or resource-scarce environments, but also real-time adjustment of content and process (Selvaratnam & Sankey, 2021; Moldovan et al., 2024). However, researchers highlight the continued need for investment in digital infrastructure, regulatory adaptation, and strategies to address digital literacy gaps (Waithira et al., 2024; Mnisi, 2023).
In summary, the current body of literature strongly supports the assertion that integrating Lean and micro-credentialing is a promising pathway for advancing sustainable, adaptive, and equitable governance in the public sector (Martha et al., 2021; Brunetti et al., 2020; Hegedić et al., 2024). Such integration fosters a learning ecosystem that aligns capacity-building with operational needs, incentivizes innovation, and supports the continuous improvement required for effective environmental and public health policies. The next section will detail the methodology adopted for the empirical analysis presented in this article, building on the theoretical foundation established here.
