Putting DGL into practice: questions and answers

Question 1

Where do I start with DGL?

Accepted Answer

Start with a defined process, technology or circularity question, not with the whole company. Agree the decision, the evidence and the people who need to take part, and consider the operational, digital and circular implications from the outset. A baseline from a multi-level maturity assessment helps you see where you are and what gap holds you back.

Question 2

Can I start with one process?

Accepted Answer

Yes. Integration means considering the three agendas together when setting direction and priorities; implementation can still proceed in phases. A factory may start with one process or problem while thinking through the operational, digital and circular consequences from the beginning.

Question 3

What governance does DGL need?

Accepted Answer

The thesis points to cross-functional steering committees with real decision authority (not advisory roles), integrated dashboards that make trade-offs visible, escalation processes to resolve conflicts between Lean, digital and circular logics, and resource allocation that funds integrated initiatives rather than forcing the three programmes to compete for the same budget.

Question 4

Should Lean, digital and sustainability be separate programmes?

Accepted Answer

According to the thesis, DGL transformation fails when treated as three parallel programmes with separate champions, budgets and performance metrics. The tensions between the paradigms need active governance, not organisational separation, so executives should position DGL as one integrated transformation.

Question 5

How should dashboards be designed for DGL?

Accepted Answer

Display operational, digital and circular metrics together on team performance boards and integrated dashboards so that trade-offs are visible and siloed optimisation is prevented. In the European case, environmental KPIs sat on the same daily management boards as throughput and quality.

Question 6

How do I use A3 for circular issues?

Accepted Answer

A3 problem solving applies directly to circular material flow challenges, according to the thesis. In the case study, site observation checked whether A3 was being applied to material recovery questions, and the DGL tension guidance suggests using A3 together with a joint review of operational and circular metrics.

Question 7

How should gemba walks change?

Accepted Answer

Gemba walks should examine digital systems and circularity performance alongside physical process conditions. The thesis also asks executives to take part in gemba walks that look at both digital and physical processes, to raise circular material flow questions in business reviews and to include DGL integration challenges in their own development goals.

Question 8

How can executives signal priorities?

Accepted Answer

Through visible and consistent behaviour: joining gemba walks on digital and physical processes, raising circular material flow questions in business reviews and including DGL integration challenges in their own development goals.

Question 9

Should I digitalise an unstable process?

Accepted Answer

In both case companies, digitising unstable processes generated data without insight, automated reporting of dysfunctional practices. The maturity descriptors also say production lines and cycles are improved before digitalisation to avoid automating the error. Selling or buying digital solutions in areas with weak Lean foundations produces data without insight and investment without return.

Question 10

How do I choose a technology?

Accepted Answer

Start from the business problem and operating context, then assess options against process needs, data, people, integration and implementation requirements. The aim is to connect a use case with practical adoption and value; installing a tool is not proof of transformation.

Question 11

How do I know if I am ready for technology?

Accepted Answer

The thesis suggests the more durable opportunity lies in assessing DGL readiness before technology deployment and designing implementations that build on process stability. Organisations should assess their current digital maturity and make sure they have the skills to implement and manage the technologies.

Question 12

How do I engage frontline employees?

Accepted Answer

Involve people in defining problems, testing use cases and improving standard work, and make sure ideas connect with decisions and feedback. The maturity model expects job insecurity from new technology or circular change to be addressed explicitly, and the case study reports that the Lean culture of respect and participation carried over to circular transformation.

Question 13

How long does a DGL transformation take?

Accepted Answer

The thesis describes three rhythms: Lean results appear within weeks, Industry 4.0 investments mature over months to years, and circular transformations take years. Building the culture and leadership capabilities takes years, and the maturity model provides a realistic frame for managing expectations. No fixed duration or result is guaranteed.

Question 14

How do I scale a pilot?

Accepted Answer

Protected pilot spaces worked for experimentation in both case companies, but transferring the insights back into routine operations was difficult. The guidance is to give pilots owners and a defined path into normal operations, and to agree up front how results will transfer.

Question 15

How should I measure circularity next to efficiency?

Accepted Answer

One company experimented with operational efficiency measured monthly and circularity capability quarterly or annually; another embedded circular targets in annual planning. Both helped without fully resolving the tension. Define baselines, owners and review periods, and distinguish revenue, savings and cost avoidance.

Question 16

How do I avoid double counting benefits?

Accepted Answer

Define baselines, ownership and review periods and distinguish revenue, savings, cost avoidance and other effects. Claims should rest on evidence, with attribution and double counting considered; the career page itself warns that different programme scopes must not be added together.

Question 17

How do I avoid greenwashing?

Accepted Answer

The thesis notes that opportunity-driven approaches risk greenwashing without accountability, and that the Middle Eastern company recognised the need for accountability structures to validate its claims. The DGL site adds that meeting a requirement does not automatically create differentiation or prove a sustainability claim; invest with evidence and clear responsibilities.

Question 18

How do I involve suppliers and customers?

Accepted Answer

Circular Economy extends the unit of analysis beyond the factory to suppliers, users and reverse logistics. In the case study both companies still faced challenges in customer-supplier alignment on circular practices, and the maturity model expects DGL to be developed with customers and suppliers, with systems integration and clear roles.

Question 19

Is DGL realistic for SMEs?

Accepted Answer

The thesis cautions that SMEs face resource and capability constraints that make the higher maturity levels unrealistic without external support, and may need substantially different frameworks. The tension and capability concepts transfer better than the implementation details.

Question 20

Does DGL work in other regions?

Accepted Answer

The study covers European and Middle Eastern contexts. Asian, North American, Latin American and African institutional contexts would likely reveal additional pathway variations not captured in the thesis.

Question 21

How do I handle pressure from headquarters for quick results?

Accepted Answer

Both case companies faced pressure from headquarters and external stakeholders to show results quickly while capability building takes years. The maturity model offers a realistic timeframe for expectation management, but aligning stakeholder time horizons is a continuing leadership challenge; the thesis recommends structural protection of long-term investments from quarterly pressure.

Question 22

Is DGL a replacement for Lean Six Sigma?

Accepted Answer

No. DGL builds on the Lean foundation and extends it. The thesis describes DGL as a fourth-generation evolution of Lean Manufacturing; existing Lean, digital or sustainability programmes are a starting point, and DGL examines overlaps, gaps and conflicting priorities rather than discarding useful systems.

Question 23

How does DGL relate to ESG?

Accepted Answer

DGL is an operational and organisational framework, not a reporting standard. It examines how Lean, digital and circular decisions interact in production and what culture and leadership they need. In the case study, ESG rating platforms were one of the external pressures shaping European operations.

Question 24

Where does AI fit in DGL?

Accepted Answer

AI belongs to the Industry 4.0 side, supporting monitoring and adaptive decisions. The tension guidance insists that algorithms support rather than replace judgement: controls to balance human and machine decisions, fact-based decisions and layered jidoka. DGL also assesses AI investments against a defined business need.

Question 25

Where do robots and cobots fit?

Accepted Answer

In the maturity descriptors, robots are considered part of the team and an input for problem solving, autonomous robots are placed in high-risk areas and cobots in high-physical-effort tasks, while people are prioritised over technology in low-physical-intensity jobs. A human-centric culture remains the stated objective.

Question 26

Where are digital twins useful?

Accepted Answer

Digital twins and simulation test possible changes before they are made. The maturity descriptors expect deep learning and simulations in every process or product redesign to optimise the improvement cycle and cost, and simulations before digitalisation help avoid automating errors.

Question 27

What circular indicators can a plant use?

Accepted Answer

The DGL sources do not prescribe a fixed list. Measures should fit the agreed problem and can include quality, delivery, cost, productivity, resource use and capability development. The concept paper also notes that better metrics are needed to show the impact of circular initiatives.

Question 28

How do I handle variable recycled input?

Accepted Answer

In the European case, the answer was semi-autonomous circular material streams with different performance expectations, which allowed variable-composition returned aluminium and buffer inventory to be handled without breaking the main flow. The thesis notes this is an adaptation, not a resolution, and challenges Lean's seamless flow ideal.

Question 29

Is compliance enough?

Accepted Answer

Reliable compliance establishes a necessary baseline, and in Europe decades of regulation created embedded monitoring capabilities that also feed Lean improvement. Beyond that, organisations can examine whether the same capabilities create customer value, better resource use or new offerings; meeting a requirement does not automatically create differentiation.

Question 30

Should companies participate in shaping regulation?

Accepted Answer

The thesis reports that organisations which participated in regulatory development, contributing expertise and helping design what compliance looks like, built more sophisticated capabilities faster than those that waited for finalised requirements. It proposes co-production between regulators and industry experts.

Question 31

Is DGL human-centric?

Accepted Answer

Yes. The culture and leadership focus, the culture-of-respect characteristic, servant leadership and the principle that technology supports people all place people at the centre. A European plant manager summarised it as 'we always say 70% people and 30% machines'.
