At a glance, method and process may seem like the same thing, but a closer look reveals their distinct differences. A method is a how you do something, while process is putting methods through an established routine.
Don't get stuck thinking a process will solve your problems because without effective methods, you're likely to end up with an uninspired result. At ZURB we call small, subtle surprises "wow moments" — they delight users and create value for a website or application. They're unlikely to happen without talented people who use methods that inspire your team. Finding these gems doesn't happen by using a process, you need methods that push your team to look at the problem from a different perspective without a lot of overhead.
We often use sketching to uncover interactions, brainstorming and mind mapping to push our product ideation, and observation when discovering problems with a website. Before starting your next design project, develop some methods of your own for unearthing your own gems. Users will appreciate those wow moments, not the process you used to create them.
