All should take part in git review for each other and try to learn the trades of each other. In fact the learning should be formalized in rotating bi-weekly "apprenticeships designations" where pairs of team members are responsible for mentoring each other in their respective fields of expertise. For example dev-ops will teach deployment in kubernetes to UX, UX will teach user testing to dev-ops.
The actual work for the project will be the learning material used. In this example UX Tasks will be assigned 25% to the UX apprentice with the tasks with most learning potential being assigned first.
The idea is that by doing things you are not comfortable with you will be on high alert and your attention to detail and best practices will be heightened. By having an expert by your side you can maintain confidence that the result will pass the bar.
For larger projects multiple swat teams will work together. The apprenticeship is maintained within each team, and each team is responsible for one easily separable part of the project. Rotation of the members will happen between teams, so that the UX of one team will swap with the UX of another, facilitating cross-team knowledge sharing while still maintaining coherent teams.
