The PLIVA index is a means of categorizing projects and tasks.

PLIVA, known as the PLIVA Pentacled Index, is divided into five categories (sometimes called "indices").

• Personal, which relates to internal matters of philosophy and framework.
• Linguistic, which relates to communication and language.
• Interactive, which relates to anything that has an input and an output.
• Visual, which relates to things to be seen.
• Audio, which relates to things to be heard.

These categories are useful in orienting oneself towards the development and expression of a well-rounded, general set of creative skills. The indices may also be used as lenses by which the world and its complexities can be viewed and broken down.
