each other to transform inputs into outputs to achieve a goal

8. People: People or organizations that have both an interest in and an influence on the creation,
implementation, or operation of an IS
Ex: friends add comments to the website about what locations they like

connectivity, that makes up an IS. Technology enables processes to perform the steps they were
designed to accomplish
Ex: function on the website for your friends to rank the trip locations in order or
preference

action
