Guido Jansen, a CXO specialist with 10 years of experience, discusses building an optimization team. He notes that people and process are crucial and that teams should start with roles like UX researcher, UI designer, and frontend developer at Level 2. As teams mature to Levels 3 to 5, they need additional roles such as data analyst, behavioral analyst, and team managers. Jansen emphasizes empowering self-sufficiency through training and establishing an executive sponsor to support the full optimization cycle.
