"He always had an answer, or if he didn't have the answer, he tried to ask the clients, the users, the stakeholders." - Mirco Gerling
 
In pharmaceutical software, the wrong dose can kill someone. So when Mirco worked with a PO in that domain, precision wasn't a virtue — it was a survival requirement. The PO wrote meticulous user stories in classic "As a user, I want… so that…" format with very good acceptance criteria. The developers always knew what done meant. And when, mid-sprint, the team spotted a gap — "Is 80% tolerance of 100% or 80% of all?" — the PO was there, asking the right people, refining or splitting the story, never letting ambiguity ship. Even when half the team was out sick in winter, the remaining developers could deliver because the user stories were clear enough to stand on their own. Stories linked to automated tests. Each acceptance criterion traceable to the test that proved it. The result: a team that trusted their PO. As Mirco puts it, that trust came from one thing — the PO had already done the work needed to help the team understand what to do and how they'd know it was done.
 
Self-reflection Question: What's the level of precision in your team's user stories signaling to your developers about how much you trust them — and how much you've prepared for them?
The Bad Product Owner: The Hydra PO with Seven Heads

"If the developers had questions, the people said: 'it's not my ticket, it's not my story.'" - Mirco Gerling
 
Five Scrum teams. One Product Owner. Seven requirements engineers writing user stories alongside. Eight people doing the work of product ownership — and nobody owning any of it. Developers learned quickly that asking a question meant being bounced from one requirements engineer to another. "It's not my ticket." The eight-person PO group split into two sub-teams who, when they spoke about each other, used "you" and "they" instead of "we." Decisions made in week one collided with decisions made in week three. Mirco's intervention: treat the PO group like a Scrum team. Eight people is a team-sized group. Run retrospectives with them. Get them communicating as a unit instead of as parallel individuals. The one anchor that kept things from completely falling apart was the single PO at the top, who could still say "this feature we need at the end of the year, the other can wait." Without unified prioritization, the hydra has no direction — just seven heads pulling in seven ways.
 
Self-reflection Question: Where in your product organization are decision-makers proliferating without a shared mandate — and what's the cost in clarity for the teams downstream?

Mirco Gerling: The Silence Test — How to Know Your Team Doesn't Need You Anymore

"Don't talk too much. And only talk if it's necessary." - Mirco Gerling
 
For Mirco, success as a Scrum Master starts with a simple rule he had to fight for: don't try to be someone else. Early in his career, when people kept saying "Mirco, you decide, you're the Scrum Master," he had to do the hard work of pushing back — "no, we decide together." That instinct shapes his whole definition of success. Be authentic. Wait before you speak. Ask before you instruct. And when a discussion stalls, sit with the silence — because in most cases, someone in the team has a better idea than you do. The cleanest test of whether a team is truly self-managing? Disappear. When Mirco took two months of parental leave, his team kept running every Scrum event without him. That's the signal. If you stop sending the sprint review invite, stop preparing the retrospective, stop nudging — and the team picks it up because they own it — your work is showing.
 
Self-reflection Question: What's one thing you currently do for your team that you suspect they would do themselves if you simply stopped doing it?
Featured Retrospective Format for the Week: 1-2-4-All from Liberating Structures
Mirco's universal tool is Liberating Structures, and within that toolbox, 1-2-4-All is his go-to. The pitch: "involve everybody, especially in large groups. And there's nearly no preparation needed." His proof point — facilitating a retrospective for 60 people at the Agile by Nature bar camp in just 20 minutes. The format scales from a team of five to a room of sixty without changing its shape: one minute alone, two minutes in pairs, four minutes in small groups, then a share-back with the whole group. During a 30°C COVID summer in Hamburg, Mirco even ran retros walking outdoors with his team — station to station, down to the lake for ice cream, then back. "It was a very good and constructive retrospective." The lesson: the right structure makes you portable.

Mirco Gerling: Two Teams, One Sprint Cadence — The Hidden Cost of Synchronization

"The teams need to understand the advantage of the synchronization — but will they?" - Mirco Gerling
 
Two of Mirco's teams just got merged into one — and the brand-new, fused team is now part of a 10+ team organization trying to move from loose-coupled chaos to a standard process. Different sprint lengths. Different estimation methods. Different ticketing tools. The plan: align everyone to 4-week sprints, hold a global planning week every three months, and synchronize start and end dates across all teams. Mirco voted for 2-week sprints. The majority went with 4. And then the side effects started. Sprint reviews stack up on the same days, making it impossible for Scrum Masters to facilitate them all. Teams synchronize on paper, but interact organically across the four weeks anyway, so the cadence advantage doesn't materialize. And the merged team itself? Pushed back through Tuckman's stages by the merge — the Tuckman model reminded Mirco that "adjourning" is real, and a high-performing team starts over when its membership changes. Mirco's experiment: let faster-moving teams run two 2-week sprints inside the 4-week window, keeping organizational sync while restoring their own learning rhythm.
 
Self-reflection Question: Where in your organization is process standardization being mistaken for actual alignment — and what would it cost you to separate the two?

Mirco Gerling: The Supermarket Team That Self-Destructed Trying to Help Everyone

"They tried to help, and finally, it... it self-destructed the team." - Mirco Gerling
 
The team was the supermarket of the organization. Cloud systems, versioning, developer machines, hardware — if another team needed infrastructure, this team built it. And when other teams asked, the answer was always the same: "We will try, we will try." Mirco watched what happened next play out in slow motion. The team escalated their overload to management. Management responded the way management often responds — sent in temporary help. The reinforcements solved problems quickly and left. But every system they built became permanent maintenance work for the original team. The pile grew. The team shrank. People left for other teams, or left the organization entirely. The escalation that was supposed to save them became the signal that broke them. As Mirco puts it: running to the higher level "sends a signal that self-organization or self-management does not work." Sometimes the help is the harm.
 
In this segment, we refer to the dynamic of team self-organization and how it can break down under pressure.
 
Self-reflection Question: When your team is overwhelmed, what does the act of escalating tell management about your ability to self-manage — and is that the signal you want to send?
Featured Book of the Week: The Kanban Maturity Model
In this episode, Mirco also recommends two books that shaped his thinking on process and estimation. The first is #NoEstimates by Vasco Duarte, which inspired Mirco to drop story-point estimation in some teams and simply count completed tickets per sprint. The second is the Kanban Maturity Model — a book Mirco uses to run workshops where teams discover their current level of process maturity. "The highest level says that you have a standardized process, and the result is always the same for the same type of work," he explains. Most teams start at level zero, but that's the point: knowing where you stand is the precondition for knowing where to go next.

Mirco Gerling: When the Scrum Guide Isn't the Rulebook — A Scrum Master's First Conflict with Management

"I had to learn that the organization didn't know the Scrum Guide very exactly." - Mirco Gerling
 
In his first Scrum Master role — running hybrid as both developer and Scrum Master — Mirco walked in believing the Scrum Guide was the rulebook everyone played by. The team thought so too: they were self-managing now, so they would decide. Management hadn't read the same memo. When Mirco called time on a meeting, a manager said "It's my decision when the meeting is over." When Mirco asked the team if they were happy in a retrospective, the manager saw the flip chart afterward — and from that day on, Mirco started destroying anything from retrospectives that could attract attention. The conflict wasn't about Scrum. It was about who gets to decide what. Without an explicit conversation about the limits of self-management, the team and management each assumed authority the other thought was theirs. Mirco eventually found Management 3.0's Delegation Poker — a tool that makes those invisible boundaries visible and gives teams and managers a structured way to negotiate them. The lesson: raise the topic with management before the conflict, not after.
 
In this episode, we refer to the Delegation Poker practice from Management 3.0.
 
Self-reflection Question: Where in your team's work are the limits of self-management still unspoken — and what would change if you put them on the table this week?
