Accelerating global growth and frequent man-made crises generate uncertainties and demand new alternatives and viable solutions in technology, energy, and health as well as political, ecological, and media organizations. This paper focuses on the key role of human communication and the increasing signifi cance of ‘human factors’ (HF). In technology, currently 70 to 90% of all defi ciencies originate from the complex HF-area, which includes human errors as well. In spite of human complexity, it is useful to study nature and compare it with our communication and behavior. Starting from control engineering and biocybernetics, a simple building block is discussed: the control circuit with negative feedback and stability. Two examples are then presented from biology and mechanics to illustrate communication, cooperation, self-regulation and stabilizing mechanisms: (i) The mutualism between a tree and animals with fast adaptation to new symbioses and (ii) The elastoplastic, self-controlled buckling with ‘snap-through’ and stabilizing mechanisms. Observing human behaviour and nature lead to an integral mental approach with the Limbionik® Method (LM), which focuses on inter- and intrapersonal communication. The HF is assessed, utilizing what is called the UB or ‘Urbewusstsein’. Next the objectives, assumptions, features and the basic LM methodology are discussed in detail. First experience with individuals and small groups is reported, covering success, performance, work and health. Generally speaking, the LM makes individuals and organizations fi t for the accelerating pace of today’s life. Three examples illustrate a successful LM application: (i) The treatment of clients, suffering from a burnout syndrome. Self-realization of their UB with personal fi lters leads them to choose a stable, lasting recovery path. (ii) A Six-Sigma project support in engineering and fabrication of large steam turbines. Including the HF into Six Sigma allowed to identify the majority of human-related root causes (80% of total) and defi ne remedies. (iii) An engineering/fabrication improvement project for large turbogenerators, involving the varnishing process of stator core sheets. Corrections included the introduction of robust machine and human processes. After summarizing the salient characteristics of the LM philosophy, future activities on both HF and LM are outlined.
