Operational Achitecture & Industrial Strategy

Fractional Chief Operating Officer (COO) & HEC Mentor,

I partner with Luxury Maisons, Impact-driven organizations, and Brands to structure their expansion, industrialize their processes, and align performance with ethics.

My mission: To secure your growth without compromising your brand’s soul ; to liberate your time so you can reclaim the serenity of your vision.

 

When ambition outpaces Organization.

 

Growth forgives no improvisation. If your creative vision is currently clashing with industrial reality, it is not a lack of talent – it is a structural flaw. 

 

The 3 warning signs

Illustration des silos entre les équipes créatives et la production dans l'industrie de la mode. Frein majeur à la performance opérationnelle.
SILOS & FRICTIONS

 

Your Studio and Production teams are speaking different languages. Collections are delayed, costs spiral, product quality drops, and energy is wasted in internal conflict.

GREENWASHING TRAP

 

Your CSR commitments are noble, but they shatter against industrial feasibility. Your lack real traceability and concrete levers to transform promises into competitive advantages.

GROWTH vs MARGINS

 

Your expansion threatens your profitability and your brand’s DNA. You’re too deep in the weeds to gain the perspective needed to pilot with serenity.

I do not intervene to make things « better ». I intervene to restructure the model and guarantee longevity.

 

Dr. Amandine Cha-Dessolier, expertise forged on the Ground : +15 years of Operational Excellence. 

From building a GOTS certified industrial textile supply chain  from scratch (LTA SAS, 200 retail points across Europe) to leading cross-functional programs involving 100+ collaborators for Luxury and Impact sectors, my journey is unique. As a PhD in Philosophy and a former CEO, I blend systemic vision with execution rigor. I do not simply advise; I implement the processes, tools and teams that makes your ambition sustainable.

People are the cornestone of responsible excellence and brand longevity. Through operational rituals, I am committed to growing teams by instilling a culture of excellence. This fosters a quality of work life where every individual find meaning. To transmit knowledge is to realign with the essential : understanding that tools and processes are not ends in themselves, but the most effective means to preserve your brand’s heritage.

I work exclusively with leaders who share my values : Ethics, Excellence, and Courage. If you seek soft consensus or cosmetic solutions, we are not a match. To ensure the excellence of my interventions, I voluntarily limit the number of active mandates each year.
