These are at the core of the behaviour of the individual. Upbringing, education and experience help to shape the values and beliefs. Every new experience in life, be it at work or at leisure, adds to the pool of preferences and attitudes, or changes a previously held notion. Over time, some habits form, preferred ways of doing things. In an organisation many individuals meet and work together.
Different groups come into being.
Some are organised by managers, others are informal. The groups influence the behaviour of the individuals organised within them. The individuals within the groups make up the rules and norms for the behaviour of individuals. Unwritten and written rules are developed that guide the behaviour within the groups and between groups. Such is the strength of these unwritten rules that changing them can be very difficult or even impossible in the short term.
