ZBTOS™ · transformation capability

Turn strategy into the operating requirements your transformation must satisfy.

ZBTOS™ equips transformation leaders and practitioners with a common operating system, working instruments and applied methods to make required change explicit, govern the work, and prove what actually converted.

The missing layer

Your transformation can be fully active and still leave the operating model unchanged.

Workstreams launch. Milestones turn green. The plan moves. But if you are accountable for the transformation, the harder question is whether the way the enterprise produces value actually changed.

The operating model

An operating model is a collection of integrated end-to-end value streams and lifecycles/workflows engineered and orchestrated to produce scalable value.

That is the layer ZBTOS teaches you to work on.

Define what must become true. Read the work against it. Govern the change until the evidence holds.

The system

Two models make the work explicit.

One defines what your operating model must make true. The other shows how to read the work moving through it. Your teams learn to use both, so the sponsor gets one definition of the change, read the same way by every team that carries it.

01 · Operating Requirements Model

Five questions every operating requirement must answer.

The bridge from strategy to the operating model holds only when all five are answered. Take one out and watch what reaches the other side. Your teams learn to write requirements that answer all five before the work is funded.

02 · GSDPI™ · The Sheet And The Stack

Your business already runs through five functions: GET, SORT, DO, PROVE and IMPROVE. The question is whether anyone can see, govern and improve how they work together.

Five functions. Six ways to read them.

Hold the five still, follow one flow through them, or see every flow at once. Three of the six reads, each answering a different question about where the transformation stops producing value. Your teams learn to read their own flows this way, so the sponsor sees where value is lost before the next phase is approved.

The five standing operating functions

Read down the system. Each function is a standing part of the operating model, with its own entry conditions, logic, evidence and owners — present whether or not anyone is managing it.

Business work moving through them

Read across the flow. A unit of business work travels the functions in phases — and the questions worth asking are where it slows, loops, bypasses a gate, or arrives with no governed origin.

The integrated execution path

Read the whole thing at once: the cross-functional conditions, handoffs, decision rights and accountabilities that must be enabled for the system to work. This is where most transformations are actually lost.

Read one part. Follow one flow. Inspect one function across the enterprise. See the whole.

From the transformations behind the method

What changes once the work is visible.

“What surprised me was how quickly the picture became undeniable. We had done the blue-chip consulting exercise before; this was different. The transformation finally felt like something we could run — not a deck we were expected to admire.”

SVP, Global Services Operations · Enterprise software

“We had mapped the process before and thought we understood it. We didn't. ETEGY's work made the hidden dependencies and single points of failure explicit — once the work was visible, many of the political arguments lost their grip.”

Chief Transformation Officer · Industrial Services

“For the first time, the value case and the operating commitments were in the same conversation. We could distinguish what was forecast, what was underwritten, and what had actually been proven.”
