"The healthier your collaboration with other roles — developers, product owners, managers — the more successful as a Scrum Master you are." - Efe Gümüs
Efe defines Scrum Master success not through team velocity or timely deliveries, but through the health of relationships. A successful Scrum Master actively contributes to organizational matters, increases transparency on both problems and solutions, and bridges the gap between roles. At the team level, the signal is clear: if people feel safe enough to approach you with their problems, if they speak freely in team events without fear of blame, if they can raise risks before the last day of the sprint — that's success. But Efe is honest about how hard this is to maintain. Relationships with stakeholders have constant ups and downs, and the work of understanding people never stops. His advice starts with empathy — not just reading the room in the moment, but understanding that every colleague carries a different career history, different coping mechanisms, and different experiences that shape how they react to change. For younger Scrum Masters especially, Efe emphasizes that what worked for you won't work for everyone. Speak the common language, understand their perspective, give them assurance through visible, outcome-focused progress. The health of those relationships is the measure of your impact.
Self-reflection Question: Beyond metrics and deliverables, how would you describe the health of your relationship with the key stakeholders around your team — and what's one thing you could do this week to strengthen the weakest one?
Featured Retrospective Format for the Week: The Diamond Retrospective "When you have diverse perspectives, a growth zone, converged thinking, and then action points — that diamond — people actually own the actions." - Efe Gümüs
Efe doesn't name a single retrospective format as his favorite — instead, he describes the structure that makes any retrospective effective: the diamond. Start by opening up diverse perspectives (diverge), create space for exploration and growth (the growth zone), then converge the thinking toward clear action points. This diamond pattern — diverge, explore, converge, act — ensures that the team moves from broad reflection to specific, owned commitments. The key word is "owned": when people arrive at actions through this structured exploration rather than being told what to improve, they commit to the follow-through. Efe connects this directly to his broader philosophy: the best systems don't depend on any single person, and the best retrospectives produce actions that the team drives forward without needing the Scrum Master to push.
