Current public interest design practices operate as a community project where everyone works together. It may be working in different sections or areas but they all work towards the greater public good. There are some that work for a profit but I feel that more and more will become non-profit if they keep going in the current direction. The strategies that seem to be effective are using the technology that is available at the time but striving to use the newest technology on the market in order to expand the possibilities. Public interest design practices can be sustained and expanded by collaborating with other practices as well as from other countries.
The participation of everyone is what makes public interest design important thing about public interest design.
