Rousseau and ten Have (2022) define "Evidence-Based Change Management" as the science-informed practice of managing planned organizational change. They state that it "reflects two key principles: 1) Planned change is more likely to succeed when using science-informed practices, and 2) Regular use of four sources of evidence (scientific, organizational, stakeholder, and practitioner experience) improve the quality of change-related decisions." There are two sets of science-informed practices that they suggest "1) Ongoing Actions used throughout the change process (e.g., goal setting, vision communication, and feedback/redesign) and 2) Phased Actions each timed to a specific change phase (e.B., early diagnosis or late-stage institutionalization)."

Question 1: Why, in your judgment, does Evidence-Based Change Management need both sets of practices?
