Collective ownership and standards are basic quality practices that apply to all teams, regardless of their domain or work product. They promote shared responsibility, accountability, and alignment among team members and across teams1. They also enable faster feedback, continuous improvement, and reduced waste2. The other options are not basic quality practices, but rather specific techniques or approaches that may be useful for some teams or domains, but not all. Agile architecture is a way of designing and evolving systems that support the delivery of value and quality3. Rapid prototyping is a way of creating and testing a minimum viable product (MVP) to validate assumptions and learn from customers4. Modeling and simulation are ways of representing and analyzing complex systems or phenomena using mathematical or computational methods.
