Decision-making in learning design involves a complex, dynamic and multifaceted process. This process takes place within an ecosystem where decisions in one area influence others, emphasizing the non-linear and interconnected nature of the process. The dynamic nature of decision-making needs to be discussed through the partnerships between instructional designers and instructors and the scope of decisions each party has. Instructional designers who work closely with faculty may have increased influence in the decision-making process due to the trust and confidence that instructors have on them. Therefore, the decision-making process becomes collaborative, where both instructors and instructional designers together make deliberate decisions to ensure all students succeed in their learning journeys. In addition, anchoring collaborative decision-making on principles of social justice can help support a student-centered learning environment where all students' experiences are valued, and their voices are heard.
