What about accessibility?

Accessibility is a sensitive side of the design process. Whenever designing a product, we should keep in mind that our product can be used by physically disadvantaged people. Hypothetically speaking, I prefer incorporating the a11y principles from an early stage, but this is usually not the case. I did an accessibility practice on an existing product last month. It was painful to check every principle, to write a report on the issues and developments in need. However, it was a really nice task to do and a sweet practice in terms of accessibility awareness. Your co-workers' accessibility awareness is also significant at this point, you need a11ys to carry out a fruitful working process.
