	12 General Principles Homogenity - Diversity

	Change from homogeneous structures, systems or environments to compound structures, and dissimilar systems or environments. Reduce the degree of diversity in the structures, systems or the environment.
	The different components are to perform different functions and should be individually matched to the local requirements. Minimize losses (cash, personnel, energy) during restructuring or re-organisation processes. Remove all ''foreign bodies'' from the systems and organisations wherever possible. Try to remove the unwanted interaction between two elements of a system not by introducing foreign ''separating substances'' but rather by modifying the existing resources. Every system defends itself against ''foreign'' elements. Avoid 'gaps' (personnel, information, finances etc.) in systems or organisations. Immediately fill every available 'gap' with up-to-date information, tasks, etc. Related technical TRIZ Principles: 3. Local Quality , 12. Equipotentiality , 31. Porous Materials , 33.

EXAMPLE:	The employees of a company change their field of activity every 3-4 years while remaining at the same level of responsibility - a so-called "'horizontal'' job rotation. This helps to widen experience and competence not only individually but also collectively. Internal customers are equally important as external customers. Customer participation within product development, where the customer and the developers are on the same basis, enables greater focussing upon the customer's requirements whilst increasing the customer's acceptance of technical problems or delays. A research or project team made up of staff members with a variety of experience, skills and competency or even nationalities and ethnic backgrounds will be particularly successful. A combination of different technical and methodical means of training and instruction: seminars, workshops, Internet, on-the-job training etc. A successful business policy of a company is a combination of investments or projects, which carry a low and high business risk.
