Since activity systems interact with each other, the development of one will influence the development of others, as well as the entity system as a whole.

Balanced development involves balance between different activity systems (e.g. between work and parenting, between nutrition and exercise).

The three-fold organisation of an entity system also requires balanced development between the three types of activity systems. Imbalance can arise from emphasising outward-directed activity systems (e.g. the work activity system) at the expense of inward-directed ones (e.g. the nutrition and sleep activity systems). Eventually, this will also affect the entity system (e.g. cause burn-out in the person or disease in the body). Or, the overemphasis of inward-directed activity systems (e.g. sleeping) at the expense of outward-directed (e.g. work) or self-directed activity systems (e.g. learning) could result in the stagnation of the entity system (e.g. a lethargic or boring person).

relevance

The development of an entity system depends on the state of development of each of its activity systems as well as the balance between them.

relevance for the change manager

As organisations grow their business (i.e. develop their outward directed activity systems), they sometimes neglect the inward and self-directed activity systems associated with business support and organisation support functions, as well as the development of the systems in the inner environment (i.e. staff development). This can jeopardize the long-term survival of the organisation.
