Selected outcomes from Jon Dajci's career prior to and alongside establishing Dajci Advisory.

Technology rarely fails because nobody bought enough technology.

It fails when architecture becomes fragmented.

When suppliers drive decisions instead of the organisation.

When security arrives too late.

When an AI pilot becomes an enterprise platform without anyone deciding how it should be governed.

Or when transformation creates another layer of complexity instead of removing one.

Dajci Advisory works with organisations at those moments.

We combine enterprise architecture, hands-on technology experience and senior advisory capability to help leaders understand the problem, make the right decision and turn that decision into something that can actually be delivered.

What We Do

From strategy to architecture to delivery.

Dajci Advisory operates across six connected areas.

Enterprise AI and Agentic AI

Move from AI experimentation to controlled, scalable enterprise adoption.

AI is becoming part of the enterprise technology estate. That means identity, access, data, security, cost, lifecycle, monitoring and ownership matter just as much as the model itself.

We help organisations create the architecture and operating model needed to adopt AI responsibly without slowing innovation to a halt.

Turn AI from a collection of pilots into an enterprise capability.

Areas of support

Enterprise AI strategy
Microsoft Copilot
Copilot Studio
Agentic AI
Azure OpenAI
AI architecture
Agent lifecycle governance
Identity and access
AI security and threat modelling
Data protection
Connector governance
Cost governance
AI operating models
AI readiness assessments
Production design patterns

Enterprise Architecture

Create clarity across complex technology estates.

Architecture should help an organisation make decisions. Not create another committee.

We help organisations understand their existing estate, define where it needs to go and establish the principles and governance required to get there.

Architecture should reduce complexity, not document it.

Areas of support

Enterprise architecture
Target-state architecture
Technology strategy
Application landscape mapping
Application rationalisation
Architecture principles
Architecture standards
Design Authority
Architecture governance
Integration architecture
Data architecture oversight
Technology roadmaps
Architecture impact assessments
Technical design assurance
Investment decision support

Cloud and Microsoft Platforms

Modernise critical platforms without losing control of the estate.

Dajci Advisory has deep experience across Microsoft enterprise environments, including Azure, Microsoft 365, Entra, Dynamics 365, Power Platform and the Microsoft security ecosystem.

The focus is broader than deploying products. We look at how platforms fit together, how they are secured, who owns them, what they cost and how they support the wider technology strategy.

Use the platform strategically, rather than simply because you already own it.

Areas of support

Microsoft Azure
Microsoft 365
Entra ID
Dynamics 365
Business Central
Power Platform
Copilot
Microsoft Purview
Microsoft Defender
Microsoft Sentinel
Intune
Hybrid cloud
Tenant strategy
Identity architecture
Cloud migration
Legacy modernisation

Cyber Security and Identity Architecture

Design security into the technology decision.

Security architecture works best when it is part of the design from the beginning.

We help organisations connect identity, cloud, data, endpoints and security controls into an architecture that teams can actually operate.

Security that enables the architecture rather than fighting it later.

Areas of support

Zero Trust
Entra ID
Conditional Access
Identity architecture
Privileged access
Microsoft Defender
Microsoft Sentinel
Purview
Data loss prevention
Security architecture
AI security
Threat modelling
Security design assurance
Cloud security
Control architecture

Technology Transformation

Turn transformation strategy into a technology estate that actually changes.

Large programmes often become consumed by governance, suppliers, dependencies and legacy constraints.

Dajci Advisory helps provide the architectural leadership needed to keep the programme connected to its original objective.

Transformation should leave the organisation simpler than it found it.

Areas of support

Transformation architecture
Programme architecture
Technical leadership
Migration strategy
Transition planning
Integration
Design Authority
Delivery assurance
Platform modernisation
Operating-model design
Technology rationalisation
Programme recovery

Supplier and Technology Assurance

Get an independent view before making an expensive decision.

Technology suppliers know their products extremely well. They do not always know what is best for your organisation.

We provide independent technical and commercial challenge across supplier proposals, architecture, delivery and major technology decisions.

Someone in the room should be working only for you.

Areas of support

Supplier architecture review
Technical due diligence
Proposal assurance
Solution review
Contract and deliverable review
Cost benchmarking
Vendor challenge
MSP governance
Service transition
Technology investment assurance
Independent architecture review

How We Work

Senior expertise without the traditional consulting model.

Not every problem needs a large consulting team. Sometimes an organisation needs someone senior enough to understand the strategic problem, technical enough to challenge the solution and experienced enough to help get the decision made.

Advisory

Focused support for CIOs, CTOs, CISOs and technology leaders facing a significant decision.

Architecture Leadership

Embedded enterprise or solution architecture capability for programmes requiring senior technical leadership.

Independent Review

A focused assessment of architecture, AI strategy, security, suppliers or programme direction.

Transformation Support

Longer-term engagement supporting complex change from architecture through delivery.

AI Readiness Check

Is your organisation ready for enterprise AI?

Eight questions. Two minutes. An honest read on where your organisation sits, and a recommendation for what to do next. Your answers stay in your browser.

The Problems We Like

Bring us the difficult ones.

"We've bought Copilot. What happens now?"

"We have dozens of AI use cases and no operating model."

"Our architecture has become too complicated."

"We don't have a clear view of our application estate."

"Our suppliers are driving too much of our technology strategy."

"We need to modernise without disrupting the business."

"Security and delivery cannot agree."

"We're spending more on technology but getting less simplicity."

"We need an independent view before committing to this platform."

"Our transformation programme needs stronger technical leadership."

"We have five vendors giving us five different answers."

Those are usually the interesting conversations.

Better technology starts with better decisions.

Whether you are adopting AI, simplifying architecture or preparing for a major transformation, the first step is understanding the problem properly.
