Homeostasis is the maintenance of a constant internal environment of a cell or an organism‚ despite fluctuations in the external environment of that cell or organism. The internal environment is set to function at its optimum rate - and it is dependent on variables such as body temperature‚ blood pressure and blood sugar levels. These need to be maintained despite changes in the external environment as well as the extent of activity and the diet of the organism. These variables are controlled by

Introduction: This document investigates Soft Systems Methodology‚ which is a way of dealing with problem situations in which there is a high social‚ political and human activity component. SSM varies from other methodologies as it does not deal with the HARD problems that are more technically oriented but instead it deals with SOFT problems as will be discussed in detail later on in this report. SOFT SYSTEM METHODOLOGY: Soft System Methodology is the brainwave of Professor Peter Checkland. The

maintain a constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibrium. This action primarily aims to preserve relative constancy in the body when severe changes occur in the external environment‚ as it very important for the body to maintain homeostasis in order to survive. If conditions happen to drift too far‚ certain biochemical reactions are ignited

Ecological theories of human development consider the complex interactions between humans and their changing social and physical environments. Every member of society experiences these interactions in a different manner‚ depending on factors such as the amount of resources available to them or the interconnectedness of their support system at birth. As people age and as the macrosystem itself changes in response to events‚ people within the system shift to occupy different positions in society. People

A system as described by the author is present all through human life and is developed by three or more persons who are in contact and share a common purpose; a system has a goal (growth)‚ has parts (people)‚ and an order to the parts (dynamics of people and interactions in the family). Satir’s essay is aimed at describing the continuum that interpersonal systems exist within as

Notions of ‘systems’ as ‘complex wholes’ abound; ‘systems of interest’ to engineers are understood in a distinctive way. We reveal our systems thinking through language‚ images‚ models‚ specifications & references that assist understanding. We rely on ‘user‐judged’ words such as system‚ project‚ risk‚ network‚ reliability‚ environment‚ need‚ effectiveness. Their meaning is socially constructed – even within a single discipline. System a system is a set of interrelated components working together
