The Institute of Natural Business Excellence (iNBE) does extensive research on LTR™ and NBE™. As part of the research LTR™ and Natural Business Excellence™ are compared with well-known theories, methodologies and authors. These include Maslow, Six Sigma, Stephen Covey, Process-Context-Content, IDEF and many more.
