  About PCD

Performance Centered Design (PCD) is also known as Performance Support Systems Design, Interaction Design, and Usability Design.

None of these names adequately conveys the nature of the activity, nor the value it can add to technology-dependent ventures, particularly internet-related ones.

Performance Centered Design embraces the philosophy that technology can and should be designed to facilitate high performance by its users.  The practice of Performance Centered Design encompasses the disciplines of usability and user interface design, which may be more familiar terms, while also incorporating principles of instruction, learning and behavior.  It enables us to arrive at designs for interaction with technology that ordinary mortals can use and enjoy.   It takes the guesswork out of designing and building for success with users!

As the name suggests, PCD practitioners prefer to “design-in performance” from the start, however an effort to improve the user interactions at later stages of the development of the technology will also enhance the user experience and promote the success of the product.  I can also quickly evaluate and provide concrete advice to improve any existing interface. 

Including PCD in your design and development efforts pays off by making the time users spend at your site or using your application more rewarding, encouraging longer stays, more frequent use and increased loyalty.
