Individuals, that are in every day mutual interaction and that affect behaviour and opinion of the other members of the system, are part of it. From the marriage, through the parenthood that builds a relationship among the kids, and parent-child relationship, family undergoes various changes. In order that every subsystem function in the best way possible, it is necessary to have effective interrelation, appreciation and respect. Shortcomings that can arise within a subsystem, change a constitution of a whole family as a community. Effective marriage communication, appreciation of the partner, accepting new roles, questioning one’s self and one’s actions and thinking about the changes are necessary for the functioning of the community.

Systematic action is long-life and constant process, and that is why it creates numerous challenges and dilemmas when it comes to the understanding of the right approach
