Like with all things quality is proven through practice and measures, which means quality can only be guessed at before a product is built. Like in all things here is how you do it: 1. Build a first version that works and accomplishes all initial business requirements. 2. Build test automation or inspection criteria. 3. Reflect upon what you built and watch how it’s actually used in production. 4. Measure it. Measure performance. Count user steps. Count development steps. Determine real cost of ownership. 5. Take stuff out without breaking business requirements. 6. Repeat steps 2-6. That is how you build quality whether it’s software, manufacturing, labor, management, whatever. In my own software I devised a new model to solve for this that I call Single Source of Truth. It’s like DRY but hyper aggressive and based upon empathy instead of micro-artifacts.
