HCI can be used in all disciplines wherever there is a possibility of using a computer, and because of the widespread use of computers, HCI practitioners should strive to apply their craft meaningfully together as a collective group. Best practices are a set of guidelines, ethics, or ideas that represent the most efficient or prudent course of action. Best practices are often set forth by an authority, such as a governing body or management; from an HCI perspective, they have been set out by thought leaders and pioneers in this field. Best practices come into play as a process for improving quality and creating standards that are used across products. Best practices are always evolving and adapt to new technologies, modalities, and audiences over time.
The prototyping methods we just discussed should do their best to apply some or all of these best practices. There are a number of best practices and we will cover them here.
