Provide a situation where it can/would be used.
An example of a closed system could be a call centre in which each phone operator is responsible for the client and is responsible for aiding them to choose the right insurance policy or help them in any other way. In contrast to this an open system for a call centre may involve managers and senior members of staff. For example an open system may be a manager being responsible for all of their client’s personal information, the information and behaviour of their employees as well as being responsible for each of their employees.

 In an open system a manager for example, in charge of an assembly line inside a factory may be responsible for all occurrences on every single assembly line and also he may be responsible for every one of his assembly line employees.


What it is & what it does
An open information system interacts with its environment by giving and receiving information. Closed systems operate closed off from the outer environment and all information stays within a system or network etc.

Closed systems are generally aimed towards management and senior members of companies in which certain important information like sales information is shared with management to decide what sells well and what doesn’t to anticipate what to order more of and what to order less for example when applied to a marketing perspective.
