When we implement Sitecore based projects, our approach for design consists of the following:
Creation of wireframes and design screens by our creative team for client approvals.
Translation of wireframes into responsive HTML design by our front-end developers.
Creation of Personas and problem scenarios by our business analyst.
Our understanding of SXA approach allows us to follow the agile methodology to speed up time to market by executing both front-end screens translations and back-end development in parallel.
In addition, content migration can start in early stages of the project life-cycle delivering more real and client-ready screens in each sprint.
