I interacted with different designers, they do design with their own process. their prospective are also different. some of them use different laws like (hicks law, gestalt theory and many more). so its takes time to work with a Designer as a team, in where designer having their own process. is there any common process that's used widely ?
Design processes vary among designers and among organizations. I doubt you'll find any universal design processes.
A lot of us work in Agile environments, but even then, I've found that UX Design is most comfortable outside of the sprint cycle. The best UX process I've seen is when the UX team does our research and design and iteration (in collaboration with Business Analysts, etc) until the element we're working on is ready for development. Then the BAs' user stories, linked with our prototypes, are scheduled into sprints. We then evaluate and tweak as the feature is built.
