Lean logic called for minimal work-in-process and tight specifications, while circular logic required accepting returned material of variable composition, holding buffer inventory and redesigning processes. It created semi-autonomous circular streams with different performance expectations, accepting suboptimisation for system-level circularity (Efficiency vs. Circularity).\n\nIn both companies the effective pattern between standards and digitalisation was continuous adjustment in both directions, because digitising unstable processes only automated reporting of dysfunction (Standardization vs. Digitalization). Circularity was framed mainly as compliance in Europe and as opportunity in the Middle East, and mature implementation needed both framings (Compliance vs. Competitive Advantage). Protected pilot spaces helped experimentation, but results had to be linked back to routine operations, for example by embedding circular targets in annual planning (Short-term vs. Long-term).\n\nMaking this visible in daily management means showing operational, digital and circular metrics together on team boards and including DGL challenges in problem-solving routines. These are elements from different parts of the case, presented together as an illustration.", "sources": [ { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 201", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=201" }, { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 202", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=202" }, { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 203", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=203" }, { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 205", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=205" }, { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 229", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=229" } ], "url": "https://digitalgreenlean.com/knowledge/answers.html#t-example-together" }, { "id": "p-start", "group": "Putting DGL into practice", "question": "Where do I start with DGL?", "alsoAskedAs": [ "What is the first step to implement Digital Green Lean?", "¿Por dónde empiezo con DGL?" ], "answer": "Start with a defined process, technology or circularity question, not with the whole company.

The thesis calls for structural protection of long-term DGL investments from quarterly pressure, and treats temporal governance as a necessary condition for sustained transformation.", "sources": [ { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 228", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=228" }, { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 229", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=229" } ], "url": "https://digitalgreenlean.com/knowledge/answers.html#th-temporal-governance" }, { "id": "th-policy", "group": "The doctoral research and case study", "question": "What does the thesis say to policymakers?", "alsoAskedAs": [ "Does regulation drive capability development?", "¿Qué recomienda la tesis a los reguladores?" ], "answer": "Regulatory clarity and stability matter more than stringency in driving deep capability development: the European company benefited from predictability across planning horizons. Organisations that took part in shaping regulation developed more sophisticated capabilities faster, and investments in knowledge infrastructure such as research programmes, industry associations and workforce development generate more benefit than regulatory pressure alone.", "sources": [ { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 229", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=229" }, { "title": "Doctoral thesis — Digital Green Lean (2026) · PDF page 230", "url": "https://digitalgreenlean.com/files/digital-green-lean-doctoral-thesis-2026.pdf#page=230" } ], "url": "https://digitalgreenlean.com/knowledge/answers.html#th-policy" }, { "id": "th-consultants", "group": "The doctoral research and case study", "question": "What does the thesis say about consultants and technology providers?", "alsoAskedAs": [ "What makes a good implementation partner?", "¿Qué dice la tesis de consultores y proveedores de tecnología?" ], "answer": "The most valuable partners engaged with the specific organisational context rather than generic frameworks, built client capability rather than dependency, and were honest about what their solutions could and could not deliver. Implementations that embedded capability in the client outlasted those requiring ongoing external management.
