Understanding Digital Green Lean
What is Digital Green Lean?
Digital Green Lean connects Lean Manufacturing, Industry 4.0 and Circular Economy within the same transformation approach. Culture and leadership help people develop these capabilities together and manage the competing demands they create. It is a way to examine operational decisions across the three agendas rather than run three disconnected programmes.
What do Digital, Green and Lean mean?
Digital refers to Industry 4.0 technologies and the use of information to support decisions. Green refers to Circular Economy, including resource use and value retention. Lean refers to customer value, flow, waste reduction and continuous improvement. DGL examines their relationships through the people, culture and leadership needed to put them into practice.
Who introduced Digital Green Lean in scientific research?
Ignacio S. Gatell and Lucía Avella introduced the term in their research on Lean culture and leadership, published online in November 2023 and in the 2024 journal issue. Their subsequent publication developed a maturity model. The doctoral thesis consolidated the framework and examined operational tensions.
Does integration mean doing everything at once?
No. Integration means considering the three agendas together when setting direction, choosing priorities and assessing trade-offs. Implementation can still proceed in phases. A factory may start with one process or problem while considering its operational, Digital and Circular implications from the outset.
How does DGL relate to Industry 5.0?
DGL and Industry 5.0 share an interest in sustainability and the human dimensions of transformation. DGL provides a specific lens on the relationships between Lean Manufacturing, Industry 4.0 and Circular Economy, supported by culture and leadership. It should not be treated as a replacement for every Industry 5.0 policy or framework.
Culture, leadership and people
Why are culture and leadership central to DGL?
Technology, improvement methods and Circular objectives depend on how people make decisions and work together. Culture and leadership influence learning, participation, collaboration and responses to uncertainty. DGL examines these conditions alongside operational systems so that transformation is supported by everyday behaviour.
What does Lean culture contribute to integration?
Lean culture supports learning at the source of work, respect for people and disciplined problem solving. These practices help teams question assumptions and test changes. Integration also requires leaders to recognise when conventional linear flows or fixed standards need to adapt to Digital evidence or Circular material flows.
Which leadership behaviours help an integrated transformation?
Useful behaviours include making priorities explicit, involving the people doing the work, asking for evidence, supporting experiments and reviewing consequences across functions. Leaders also need to address tensions openly and connect current performance with longer-term capability development. The right development priorities depend on the organisation.
How can employees participate in the transformation?
Employees can help define problems, test use cases, improve standard work and identify practical barriers. Participation should connect ideas with decisions, feedback and implementation rather than stop at collecting suggestions. Training and project work can be combined so that learning is applied to real operational challenges.
Can training alone deliver DGL transformation?
Training develops understanding and skills, but lasting change also needs leadership support, clear responsibilities, usable processes and opportunities to apply learning. A practical approach connects learning with improvement projects, follow-up and relevant performance measures. The mix should reflect the problem and the organisation’s existing capabilities.
Integration and operational tensions
What are the four operational tensions examined in the research?
The doctoral research examines Efficiency vs. Circularity; Standardization vs. Digitalization; Compliance vs. Competitive Advantage; and Short-term performance vs. Long-term capability development. These are persistent competing demands. DGL helps leaders work with them in context rather than assume that one universal solution will remove them permanently.
Can Circular Economy conflict with operational efficiency?
Yes. Recovered inputs, reverse logistics or additional sorting can introduce variability and coordination work. A useful assessment examines both local process performance and wider resource value. For example, a dedicated recovery stream may be appropriate even if it adds handling in one area. Such examples illustrate decisions rather than guarantee a net benefit.
How can standard work coexist with Digital experimentation?
Standard work provides a shared baseline, while Digital evidence may reveal a better way to operate. Teams can test a proposed change, assess its risks and results, and update the standard when justified. Live data should support informed judgement rather than bypass process ownership or validated controls.
How can compliance become a source of competitive advantage?
Reliable compliance establishes a necessary baseline. Beyond that, organisations can examine whether the same capabilities create customer value, better resource use or new offerings. Investment should be evaluated with evidence and clear responsibilities. Meeting a requirement does not automatically create differentiation or prove a sustainability claim.
How can short-term performance and long-term capability be balanced?
Leaders can make the different time horizons explicit, protect selected capability-building work and review it alongside current targets. Pilots need owners and a path into normal operations. The aim is to avoid both sacrificing future capability to daily pressure and funding experiments disconnected from business needs.
Assessment and roadmaps
What assessment options does DGL offer?
DGL offers a focused culture and leadership readiness assessment and a broader integrated business assessment covering relevant operational, Digital, Circular and organisational conditions. The initial conversation establishes which approach fits the problem. Scope, evidence and deliverables are agreed before the work begins.
What information is needed for an assessment?
Depending on scope, evidence may include interviews, process observation, performance data, existing strategies, technology use and examples of improvement work. Information needs are agreed with the organisation. The assessment should use evidence relevant to the question rather than request every document or assume that one checklist fits all.
What should an assessment produce?
An assessment should clarify the current situation, relevant gaps, dependencies and practical priorities. Agreed outputs may include findings, recommendations and a roadmap with responsibilities and review points. The exact format depends on the engagement; it should help leaders make decisions rather than simply provide a maturity score.
How are roadmap priorities selected?
Priorities should reflect the business problem, expected value, feasibility, dependencies, risk and organisational readiness. Operational, Digital and Circular consequences are considered together. A roadmap can combine near-term action with capability development, with decisions revisited as evidence emerges.
Can DGL work alongside existing Lean, Digital or sustainability programmes?
Yes. Existing programmes, standards and investments provide a starting point. The work can examine overlaps, gaps and conflicting priorities, then agree how the programmes should connect. It does not require an organisation to discard useful systems or replace every initiative with a new label.
Services and working together
What are the six ways of working with DGL?
The six areas cover assessments and roadmaps; business and operational performance; implementation and integration; learning and capability development; innovation management; and technology assessment and implementation. They can be scoped individually or combined around a defined business challenge.
Which sectors does DGL prioritise?
Priority sectors include industry and manufacturing, automotive, aerospace, healthcare, construction and real estate, retail, FMCG, government organisations, universities and educational centres. DGL is also open to other sectors where its capabilities fit the challenge. The approach and scope are adapted to each organisation’s processes, people and objectives.
Is support available online and on site?
Yes. Work can be delivered online, on site or through a combination, depending on the task and agreed scope. Interviews, workshops, operational observation and implementation support may need different arrangements. Location, access and practical requirements are discussed before confirming the engagement.
Who carries out a DGL engagement?
DGL brings the resources needed for the agreed scope. Some engagements may be delivered by Dr. Gatell alone; others may involve additional specialists. Roles, responsibilities and collaboration with the client’s team are established for the project. Team size is determined by the work rather than a fixed delivery model.
How do we start, and are duration and fees fixed?
Start with a written enquiry or an initial conversation, followed by an online face-to-face meeting to understand the context. Duration, fees, outputs and delivery arrangements depend on the organisation’s size and needs. No standard price or project duration is published because scope is agreed for each engagement.
Evidence, application and limits
What research supports DGL?
The primary sources are the concept paper, the published culture and leadership maturity model, and the doctoral thesis with its defence materials. They address different research questions and should be read with their methods and limitations. The reference library links directly to the publications and supporting documents.
Can the framework be applied outside manufacturing?
The research foundation is in manufacturing, including process manufacturing in the doctoral thesis. Some ideas may inform decisions in other settings, but transfer requires adaptation and assessment. Application to healthcare, retail, public services or education should not be presented as if the original research had validated outcomes in all those sectors.
How should transformation results be measured?
Measures should fit the agreed problem and can include quality, delivery, cost, productivity, resource use and capability development. Define baselines, ownership and review periods, and distinguish revenue, savings, cost avoidance and other effects. Claims should be supported by evidence, with double counting and attribution considered.
Does DGL guarantee savings or a particular maturity level?
No universal financial result or maturity outcome is guaranteed. Results depend on the starting situation, decisions, implementation and operating conditions. Historical achievements in professional cases belong to their organisations, teams and periods; they are not promises that a new DGL engagement will reproduce the same figures.
How should I cite DGL or use its materials?
Cite the relevant original publication by Gatell and Avella when discussing the scientific concept or maturity model, and the doctoral thesis for its specific findings. Use the source details and DOI links in the reference library. Reuse of website materials remains subject to the stated copyright terms; contact DGL for permission where required.
