Sparring partner · Coach · Interim manager

Stop firefighting. Start delivering.

Escalations every week. Priorities that change before they have reached the team. Commitments no one believes any more. Everyone is working flat out – and delivery still isn’t reliable.

I help leaders in software and IT organisations get their teams out of this mode: with settled priorities, steady routines and ownership where it belongs.

Fewer fires. Commitments that hold. Time for strategy and better products.

The WerteWirker approach

Solve problems where they start

No bloated programmes, no new bureaucracy. A few routines that take the pressure off quickly.

First understand where work gets stuck

More governance and better slide decks don’t make an organisation any better at delivering. What matters is how software actually gets built, and where that work gets stuck. That is where I start.

I am not part of your system. That is why I can ask the uncomfortable questions, including the politically awkward ones. The causes rarely lie in the processes; those are often well documented. They lie in the well-worn workarounds that have grown up around the official routes, for good reasons. Only you and your teams can change that. Without you, I achieve nothing.

Confident decisions when plans keep shifting

Markets move faster, dependencies multiply, plans go out of date sooner. That is no longer the exception; it is the norm. The usual reflex is more control, more alignment meetings, more reporting. That is exactly what adds to the turmoil.

What holds up is clarity about what comes first when two goals collide. That takes unambiguous goals, agreed ownership and decision rules that still apply under pressure. It applies when the pressure comes from above, too: the board decides on an AI initiative, and you are expected to deliver before anyone knows whether or how it fits your area. This is where values get practical: as the yardstick your team decides by when you’re not in the room.

The result: fewer snap decisions. Everyone can see why a decision was made, and a change of course no longer upends everything.

A sparring partner, not a ready-made solution

At the top, there is often no place for an honest conversation. Inside the company, every conversation is also politics: everyone has a position to defend. External consultants have a solution to sell. I have neither.

With your boss you want to appear in command, with your team confident, and your peers have interests of their own. In sparring you have no need to justify yourself: you get someone outside your company to test your thinking against. We untangle the issues, check assumptions and prepare decisions. No methodology dogma – what fits depends on your situation.

My role has two sides: backing when things are uncertain, and plain speaking when clarity is being avoided. Reflection isn’t an end in itself. It leads to a decision you can defend, inside your organisation and beyond it.

The name WerteWirker

What values have to do with firefighting

“As leaders, we create our impact through the values we lead by. Where they are missing, that impact fizzles out.”

Karsten Zimmer

There is no manual for leadership decisions. Under pressure, people decide by what really matters to them. That is their set of values: the answer to the question of what comes first when two goals collide. Deadline or quality? Speed or reliability? If that is unsettled, it gets renegotiated in every escalation. The glossy poster of company values in the office kitchen changes none of that: what counts is what people actually live by.

WerteWirker is a coined German word: Werte means values, wirken means to have an impact. When impact fizzles out, there is lots of work and little to show for it. That is exactly what firefighting feels like.

That is where my work starts. I am a values-based systemic coach (systemic meaning I look at the whole organisation around a person, not just the person), and I have led software organisations myself. Together we clarify the values you lead by – your own and those of your leadership team – and turn them into priorities, decision rules and routines. The result is a handful of rules for when it counts, rules that everyone involved can understand. They let you stick to an agreed strategy even under pressure. For example: consistency over speed. So ‘cloud first’ still applies, even when on-premises would be quicker.

Impact through values – hence the name.

Impact

What changes for you

When priorities stick and ownership is agreed, you’ll notice it in your own calendar first: fewer escalations, fewer emergencies, more time for the job you’re there to do.

Commitments that hold
Clear priorities make sure that what was promised gets delivered. That builds trust: with senior management, the business and your customers.
A calmer working week
Escalations, ad-hoc decisions and endless alignment meetings tail off. You lead again instead of fighting fires.
Less friction
Agreed roles and handovers end the ping-pong between business, engineering and operations: every issue has an owner, and the business gets answers instead of being passed along. And you no longer have to act as the go-between.
In short: you regain calm, a clear view and room to decide.

From the field

From one release in two years to one every nine minutes

The starting point at a large provider of digital consumer services: more than ten development teams, with every role from product management to operations. One laborious release every two years. More than 10,000 open bugs, and a dozen people doing nothing but managing the bug list. New features had stopped arriving, and so had a redesign that had been planned for two years.

The approach: I coached the leaders and the organisation. From the values the organisation actually lived by, we derived a clear set of rules. With those rules, the organisation could stick to its strategic roadmap for the first time, and the order of the features was settled. Where expertise was missing, we brought in outside experts and paired them with in-house staff who could pass the knowledge on, so that it stayed in the company.

The results: features were being delivered again. Reported bugs were fixed in under 72 hours on average. That freed up a team for the redesign towards microservices, which was completed in eight months. One release every two years became one every nine minutes. The rest of the company noticed, too: sales got reliable delivery dates, marketing could plan, customer service breathed a sigh of relief. After 24 months, my assignment was complete.

What clients say

Testimonials translated from German.

The collaboration brought structure to a very turbulent phase. Goals, responsibilities and routines were sharpened without adding bureaucracy. That helped not only me but the entire leadership team.
