Another great article from Six Revisions about design. The author wrote about the difference between good design and great design. Design need to fit with 3 perpective, from other designer, client, and user.
Truly great design, then, is when these three perspectives are considered and implemented equally to create a final product that is beautiful, effective and functional.
Keep in mind that the product must be a synergistic realization of the three perspectives and not merely contain elements ideally suited for each. The design must be attractive enough to catch a user’s attention, the message strong enough to communicate effectively to the user and the functionality simple enough to cause the user to take action.
Above is a summary about great design. You can read the long explanation and see some examples on it’s original post.
