Good article. The one issue I would take issue with is placing “usability” as the last phase of design. Usability testing with actual users can be done at any of the other phases you mentioned. If you look at Google Venture’s Design Sprint process, they recommend testing very rough prototypes at the wireframe stage at the end of the first week of work.
