Concepts that overarch several information products are defined
during the process phase of concept development. These include,
for instance, which information products are produced with which
functions and which information architecture.
A concept is intended to ensure the consistency and uniform quality of information products. This is especially important if several people are involved in creating information products.
Concepts must be reviewed routinely at appropriate intervals. A review is also required in case of special events such as, e.g., launching new products, new variants or new media.
Concepts have a direct impact on content creation and on subsequent process phases.
