Great article. Valuable insights on the matter of design management and very practical.
I myself tried to build design system three times in 2 different teams and the results were all a mixture of success and failure.
A design system is difficult to build and nearly impossible to maintain properly especially when you are dealing with complex customer facing products in a company with multiple stakeholders.
The amount of time and energy it take is just not worth it and it at best can be treated as a hi-fi mockup tool.
However, the process of making the design system does bring about learnings and does synthesize design ideology and logics within the team.
Maybe thinking holistically about the design, having reoccurring retrospect, documenting the proper structure and UI state are where the value truly lies in Design System.
