Enterprise architecture, operating model and roadmap, owned end to end by a Partner-level architect, from the first decision to the measurable outcome.
Leiven Advisory & Consulting is the strategic practice of Leiven Group. We structure the decisions that shape a transformation, arbitrate the choices behind them, and stay accountable for the outcome. Not advice handed over: decisions owned, from the boardroom to delivery.
We frame the structural choices and their sequence before anything is built.
A named enterprise architect leads the engagement end to end. One line of accountability, no handovers.
A critical view, free from any vendor or integrator interest. The recommendation serves your architecture, not a product to sell.
We stay until the outcome is delivered. Tracked at every milestone, not promised.
Design Authority is how we run a program: one named architect with real authority, a clear governance cadence, every partner orchestrated, and the business value tracked from start to finish. We own the result.
One Partner-level enterprise architect, named on day one and accountable to the end, with the authority to say no.
Structural choices arbitrated at two levels, every decision documented and traceable.
One technical line across consultants, partners and vendors, no gaps between phases.
Outcomes agreed on day one, tracked at every milestone. The architect who signs the design signs the value.
Everything the practice does converges on the same goal: decisions that hold, and outcomes you can measure.
The target architecture, the structural choices, and the authority to arbitrate them. We design the foundations a transformation stands on, and we answer for them.
How your organization will actually run: roles, processes, decision rights and governance. Designed with your teams, not imposed on them.
The sequence that turns a decision into value: priorities, quick wins within 90 days, a 12 to 24-month horizon, and the benefits tracked at every milestone.
Some programs do not need a full engagement. They need one key role, in the right seat, at the right moment. The Consulting side of the practice places experienced consultants inside your organization, selectively, where they reinforce the outcome.
Named individuals, experienced only, accountable to your program's goals. The same standard as everything we do.
Advisory engagements begin at three moments: a structural decision to frame, a program to put back on track, or a lasting mandate across your transformation.
A platform choice, a target architecture, a new operating model. The decision will shape the next decade, and it deserves to be framed before budget is committed.
The build is underway, milestones slip, and no one owns the structural call. We assess where the program really stands, rebuild the roadmap, and deliver the action plan that puts it back on track.
Beyond a single program: one architect, one governance, one benefits view across all your transformation programs. Authority as a durable capability, not a one-off intervention.
Advisory works with the people accountable for a transformation: those who sign it, those who run it, and those who answer for the architecture behind it.
Committing significant budget to a transformation, and expecting an independent, expert view before and during the journey.
Running a program with many moving parts, and needing the structure, the sequence and the governance to hold it together.
Responsible for architecture choices that will last a decade, and for making them hold as the business evolves.
The fastest way into the practice. A fixed-price architecture diagnostic, led by a Partner-level enterprise architect: your target architecture stress-tested, the priorities sized, and a decision-ready document for your executive team, all in under three weeks.
Most engagements start with a Flash Audit: a fixed-price diagnostic that gives both sides a clear view before any larger commitment. For specific needs, a direct conversation with one of our architects is the simplest first step.
No. A PMO tracks progress and reports on it. Design Authority owns the structural decisions: one named architect with the authority to arbitrate, a governance where every decision is documented, and accountability for the business value, not just the planning.
Yes, by design. Advisory does not replace your teams or your integrators. We bring the architecture layer that aligns them: one technical line, clear decision rights, and a governance everyone works within.
Yes. Framing a decision, reviewing an architecture or designing an operating model are engagements in their own right. And when a build follows, the same architect can stay accountable through the Design Authority model.
That is the Consulting side of the practice: experienced consultants, placed selectively in key roles, from Enterprise Architects to Project Managers, Business Analysts, Product Owners and Tech Leads. Named individuals, accountable to your program's goals.
Thirty minutes with one of our enterprise architects: your context, your questions, and an honest view of whether and how we can help.
No pitch, no commitment. A working conversation.
