AIGA, the professional association for design, believes that professional designers should be compensated fairly for the value of their work and should negotiate the ownership or use rights of their intellectual and creative property through an engagement with clients.

AIGA acknowledges that speculative work—that is, work done prior to engagement with a client in anticipation of being paid—occurs among clients and designers. Instead of working speculatively, AIGA strongly encourages designers to enter into projects with full engagement to continue to show the value of their creative endeavor. Designers and clients should be aware of all potential risks before entering into speculative work.

AIGA is committed to informing designers, students, educators, clients and the general public on the risks of compromising the design process though information, materials and services that can help in forging a healthy working relationship between designers and their clients.
