She coined the term “Human Systems Engineering” and gave it to a Master of Advanced Studies Program she developed at the HES-SO (University of Applied Sciences Western Switzerland).

After the end of World War II in 1945, there came 15 years of booming success and wealth in part due to business with the Allied forces which privileged partners who had not been Nazis.

In 1960, when it was clear that the German textile industry would get into heavy troubles under the pressure of Asiatic competition, Muth's mother dropped her job and withdrew out of this branch.

Muth earned her Ph.D. in 1991 at the Swiss Campus of La Jolla University, San Diego, where she attended lectures with Paul Watzlawick and Henri Laborit.

The objectives of the initiatives in which she participated invariably focused on sustainability, empowerment and creating jobs for those who were in trouble finding appropriate work in line with their values.

Some of the businesses she started have survived until today, the most notable and where she had a leading role as founder-manager for 6 years is probably Voyages APN in Geneva, originally a travel agency and coach transport company in the legal form of a cooperative.

From a methodological point of view, Muth was strongly influenced by Systems thinking (Frederic Vester[1] and James Grier Miller[2]), the model of the triune brain (Paul D. MacLean), Existential Analysis (Viktor Frankl)[3] and by the sociological research carried out by Mihaly Csikszentmihalyi.

[4] In her role as main researcher and developer for the Leonardo 3.4.5 methodology she condensed this knowledge into a tool intended to help organizations to master complexity and to assess organizational strategies in relation with mental patterns of management teams.

At this time she committed herself to reorient the printing industry to Sustainable Development providing the branch with analysis and concepts for survival in the context of globalization.

During the quality certification, esig+ became the main model for Rolf Dubs [de] who was at this time the mentor of the Swiss Confederation for the development of the Universities of Applied Sciences.

Muth strongly advocated to include soft skills and social competence in academic curricula and to transform the teaching methods and relations between faculty and students accordingly.

In 2000, esig+ was merged into HEIG-VD as department Comem+ [fr] (Communications Engineering Management) and Muth was asked to package the type of knowledge she used for the turnaround of esig+ in order to make it transmissible and teachable in a Master of Advanced Studies (MAS).

Muth was aware of her gender dysphoria since her earliest childhood and attempted several times to transition without success; rigid values in her social, professional and family context, shame and fear prevented a coming out.
