In configuration management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification.
According to the 'Oxford Colour Medical Dictionary, Third Edition'. homeostasis is the the physiological process by which the internal. systems of the body (e.g. blood pressure, body temperature, acid-base. balance) are maintained at equilibrium, despite variations in the. external conditions. Homeostasis is the maintenance of a stable internal environment within. tolerance limits, this is the restricted range of conditions where. cellular operations effectively work at a consistent rate and maintain. life. These conditions include temperature, blood glucose levels, pupil. diameter control and many more.
