At SingleStore, product design is a holistic process that involves gathering requests, ideating, and delivering pixel-perfect products. The company uses a full-stack approach where each designer takes ownership of a product or feature and engages with other team members to ensure constant feedback and iteration. This includes research, user flow diagrams, wireframes, high-fidelity mockups, prototypes, writing, and implementation. The design process is iterative, requiring patience and commitment, and involves validation through data analysis, task analysis, and customer feedback. Designing as a team and encouraging contributions from multiple stakeholders across departments are crucial to producing effective design solutions that meet customers' real needs.
