The PAR assignment asks you to explore and evaluate the state of the art of your project's technologies. This means the current state of development, such as the most-recent research, innovation, and product development. In other words, the bleeding edge.

Publications on the state of the art, such as academic journals, conference papers, and patents, can be difficult to read because they usually assume that the reader understands the technology being described.

If you want to learn more about your project's technologies and understand them better, you may find it helpful to read up on the state of the practice. This means the established knowledge about a technology. Useful publications include textbooks, regular books, and other educational and technical materials.
