How can I make a better portfolio with case studies? I'm disappointed in peoples portfolios being like an art gallery, or not organized well. I probably just need a good example.
FXquincy, you propably should describe all important aspects of some of your best projects. It may include features description, some sentences about innovative features you add, describe why are they so good, important, easy to use, include before/after comparison, user testing results
For visual designer, their works speaks for themselves, but in UX/UI design you should explain what you work consist of. Colleagues may read your level and benefits of hiring you from bare screens, but for potential employers you should explain these benefits explicitly: this will make work faster, uncluttering this screen will make it easier to work with for the first time, etc.
Take a look at http://www.artlebedev.com/everything/kommersant/ (these guys are really good of describing why are they so good).
My own case studies roughly follow this outline:
BTW, even in case of visual/communication designers the works do not speak for themselves, IMNSHO. There is always some problem to solve and the solution does not necessarily make the original starting point nor the process obvious. A designer should in any case be able to explain what the original problem was, how they arrived at the chosen solution and why they think it succeeds (benefits, added value, …).
