An Introduction to Zero-Based Transformation™

For transformation executives, initiative owners and practitioners: why so much transformation activity leaves the operating model unchanged, and the methodology that defines, reads, works and proves the change.

Chapter 01

Why activity is not change

Most enterprises run more transformation than ever: strategy programs, platform replacements, AI investments, a transformation office and a portfolio of initiatives across every function. Yet a transformation can be fully active, with every workstream reporting on track, and still leave the way the business operates unchanged.

It happens for a simple reason. Strategy is set at the top. Delivery starts at the bottom. The layer in between, a clear statement of what the operating model must make true for the strategy to hold, is rarely written down. Each team fills that gap with its own interpretation, and the work that follows is busy but does not add up.

That gap now carries a cost. Boards, investors and CFOs are asking leaders to show how a strategy and its investment portfolio will become value before the next funding decision, and the same question is being asked of technology, digital and AI spend.

What an operating model is

Ask most people how their company works and they describe the structure: divisions, functions, reporting lines. The structure matters, but work does not move through the org chart. It moves through flows that cross it. An order travels from sales to operations to finance. A hiring request travels from a manager to HR to IT.

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

Those flows are what customers, employees and regulators actually experience. The governing conditions behind them, including decision rights, capacity, economics, systems, data, controls and evidence, are also part of what a transformation must examine and, where necessary, change. That is the layer ZBTOS teaches you to work on.

Chapter 03

What makes it zero-based

Zero-based means starting each transformation from what the operating model must make true, rather than from the current list of initiatives, the existing org chart or last year’s plan. Every piece of work then has to justify itself against that definition.

It is not zero-based budgeting. Zero-based budgeting rebuilds the budget from zero. Zero-Based Transformation™ rebuilds the definition of the change from zero, and asks what the operation must become before deciding what to fund.

Chapter 04

The Governing Criteria

Before major delivery commitments are made, the enterprise needs an explicit mandate, required operating conditions, an integrated and enabled approach, and an agreed basis for proof. As execution proceeds, those conditions are tested against operating evidence. Results are claimed only to the extent the evidence supports them. Each criterion is a question an executive can ask and a practitioner must answer with evidence.

Zero-Based Transformation™: Mandate, Requirements, Integration, Enablement, Evidence
MANDATE
Is the transformation mandate coherent and authorized?
REQUIREMENTS
Is it explicit what must become true in the operating model?
INTEGRATION
Can those conditions hold together as one operating model?
ENABLEMENT
Can the required operating state be made operational?
EVIDENCE
What would permit the enterprise to claim the condition is true?

Each criterion is evaluated as Stated, Contested or Missing. Nothing is scored. They are criteria to be satisfied, not phases to complete in order.

GSDPI™: reading how the work runs

To change an operating model you first have to see it. GSDPI™ reads value-producing business work, such as order-to-cash, hire-to-retire or IT demand through delivery, through five standing functions that are present in every flow whether or not anyone is managing them.

GSDPI™: GET, SORT, DO, PROVE, IMPROVE
GET
Governed entry: how work enters the flow.
SORT
Best-fit path: how each unit of work is routed.
DO
The production system: how the work is performed.
PROVE
What it establishes: how completion and value are evidenced.
IMPROVE
The correction: how the flow learns and changes.

Five standing functions. Six ways to read them: Vertical, Horizontal, Seams, Node, Swimlane and Macro. One coordinate system. Each flow keeps its own stage names, so finance, HR, IT and operations can be compared on the same five functions.

Read one part. Follow one flow. Inspect one function across the enterprise. See the whole. How to read a flow is taught in the Foundation Course.
Chapter 06

BRACE™ for Transformation: working the change

BRACE™ for Transformation is the application process: five actions that carry one transformation from its boundary to proof that it happened.

BRACE™ for Transformation: Bound, Read, Architect, Connect, Establish Proof
BOUND
Fix the strategic intent, the transformation object, its boundary and the value at stake.
READ
Establish the current operating state through GSDPI™.
ARCHITECT
Define what must become true, including the enablement it depends on.
CONNECT
Bind each requirement to accountable work, authority, dependencies and evidence.
ESTABLISH PROOF
Determine what changed and what the evidence permits the enterprise to claim.
The five actions do not map one-to-one to the five GSDPI™ functions. Evidence found later can reopen an earlier position.
Chapter 07

ZBTOS™: one operating system

ZBTOS™ is the integrated operating system that brings the criteria, the model, the process, the instruments and the governance together, so a transformation is read, worked and proven on one system instead of many.

ZBTOS™: GSDPI™ with BRACE™ for Transformation at its center

It does not replace the methods your teams already use. Project, agile, process and change methods execute defined work well. ZBTOS™ gives them a defined target and a standard of proof, and connects them to the five criteria.

Building the capability

Transformation capability is the ability to do this with your own people, on your own work, and keep it after any program ends. It can be inspected: who can see the operating model, make the requirements explicit, trace work to its origin, govern on evidence, test whether a requirement is ready, and defend the result to finance.
