Champion’s Guide: How to navigate an EA Platform rollout

You’re sold on how and why your organisation needs Colloquial, but getting leadership and your teammates on the same page requires coordination. That’s why we’ve created this “champion’s guide” walking you through the stages of the buy-in process—to minimize the guesswork and streamline your Colloquial onboarding and adoption.

This article walks you through the process assuming you’re starting with a smaller group of stakeholders to test things out and troubleshoot before launching to a larger team. But when you’re ready for a full rollout, you can refine and repeat these steps.

Enterprise Architecture (EA) plays a pivotal role in enabling organisations to align technology with business strategy, reduce complexity, and drive innovation. But rolling out an EA platform isn’t just about choosing the right tool—it’s about leading cultural and operational change. That’s where you, the internal champion, come in.

This guide is designed to help you navigate the rollout process effectively, from building stakeholder alignment to achieving measurable impact. Whether you’re launching an EA platform like Colloquial, LeanIX, Ardoq, or Bizzdesign, these principles apply across the board.

Phase 1: Promote

Step 1 – Define Your “Why” and set measurable goals

As you make a case for Colloquial, it’s important to identify the pain points you’re experiencing and the goals you hope to achieve with Colloquial. This rallies the team around a clear future where they overcome these frustrations and operate at a higher level.

Common pain points our customers experience:

Pain Point 1: No source of truth

Nobody knows where to find the information they need, and it’s hard to trust the information that is available.

Pain Point 2: Basic questions are effort intensive

Ownership is unclear
Fragmented landscape
Redundant applications
Poor visibility into tech dependencies
Security and compliance risks

Pain Point 3: Lack of traceability of strategy to investment

You have a corporate strategy with clear strategies and goals, but you can’t trace how your technology investments are supporting these goals.

Constantly having to fight to keep resources
A barrage of new ideas keeps popping up
No clear way to assess the value of new ideas

Turning Pain Points into a Plan of Action

Translate these into clear, measurable goals such as:

Ownership and accountability model for all applications
Consolidate redundant applications by 20% in 12 months
Achieve 100% visibility into business capabilities and supporting systems
Establish architectural governance for all new tech investments

These goals help you create a compelling case for change and rally your stakeholders around a shared vision.

Step 2 – Build Your Coalition of Stakeholders

EA platform success hinges on strong stakeholder engagement. Bring together a diverse group early, including:

Executive sponsors (CIO, CTO): Focus on strategic alignment and risk management
Enterprise architects and IT leaders: Emphasize operational efficiency and governance
Security and compliance teams: Highlight risk reduction and regulatory alignment
Business analysts and product owners: Frame EA in terms of agility and decision support

Tailor messaging to each group. For example, for executives, demonstrate how the EA platform enables faster, data-informed strategic decisions. For architects, show how it reduces manual documentation and enables reusable patterns.

Step 3 – Align EA Strategy with Business Outcomes

One of the biggest mistakes in EA platform rollouts is keeping it too IT-centric. To drive organisation-wide impact and support, connect the platform to real business goals:

Support digital transformation by mapping capabilities to technologies
Accelerate time-to-market by streamlining tech onboarding and offboarding
Improve customer experience by identifying and modernizing critical systems

Map every use case back to a business outcome, and ensure leadership understands how EA contributes to overall success. This connection transforms EA from a technical exercise to a business enabler.

Phase 2: Pilot

Step 4 – Start Small: Pilot with a Core Domain

Rather than rolling out the platform enterprise-wide, start with a manageable scope. Choose a domain with clear business impact, such as finance, HR, or digital commerce.

Define specific pilot goals:

Model all applications and capabilities in the selected domain
Identify redundancy, risks, and opportunities for improvement
Collect feedback from users on usability and insights

A successful pilot builds credibility, surfaces best practices, and reduces resistance during the wider rollout.

Step 5 – Secure Executive Sponsorship

Without C-suite sponsorship, EA initiatives struggle to gain traction. Use the results of your pilot to build a data-backed case. Highlight:

Early wins from visibility and insights
Time saved in strategy and project planning
Risk mitigation from centralized governance

Provide regular updates to leadership, and ensure their continued advocacy and alignment.

Step 6 – Select an Admin Team and Platform Champions

Identify team members who will own and manage the platform. They’ll handle configuration, training, governance, and ongoing improvement.

Key roles include:

Platform admin: Handles tool configuration and integrations
EA lead: Defines modeling templates, standards and taxonomies
Curators (data stewards): Ensures consistency and data quality
Business evangelists: Promote adoption within business units

Equip this team with training and peer support to drive the initiative forward.

Step 7 – Communicate the Rollout Roadmap Clearly

Transparency breeds trust. Develop a clear, visual roadmap outlining the rollout phases:

Preparation – stakeholder buy-in, platform setup, pilot scope
Pilot – limited rollout with feedback loops
Expansion – phased domain onboarding
Optimisation – refinement and integration

Distribute the roadmap through presentations, email briefings, and team meetings.

Phase 3: Expansion

Step 8 – Integrate with Existing Processes and Tools

An EA platform must fit into the existing enterprise ecosystem. Integrate with:

ITSM (e.g., ServiceNow)
CMDBs
Agile tools (e.g., Jira, Azure DevOps)
Cloud platforms (e.g., AWS, Azure)

Embed EA into workflows such as onboarding new applications, managing change requests, and approving projects.

Step 9 – Onboard Teams with Practical Training

Create a learning program tailored to different roles:

Live demos and sandbox walkthroughs
Knowledge base articles and quick-start guides
Role-specific scenarios (e.g., architect, security, analyst)

Encourage early adopters to mentor peers and document successful use cases.

Step 10 – Set Early Wins and Quick Value Checks

Demonstrate value fast to sustain momentum. Set achievable early milestones:

Catalog all business applications within 30 days
Map at least 70% of business capabilities
Identify five areas for cost or risk reduction

Celebrate these wins internally to encourage adoption.

Step 11 – Govern for Consistency, Not Control

Governance should enable—not inhibit—collaboration. Establish flexible policies:

Standard modeling guidelines (naming, ownership, lifecycle)
Minimum metadata requirements
Review checkpoints for new applications or integrations

Use dashboards to monitor compliance and course correct when needed.

Phase 4: Embed

Step 12 – Monitor Engagement and Adoption Metrics

Track the right metrics to understand progress:

User logins and activity trends
Number of modeled applications, capabilities, interfaces
Data completeness and freshness
Feedback scores from users

Review metrics monthly and share them with stakeholders.

Step 13 – Celebrate Wins and Recognise Contributors

Cultural change happens when success is visible. Recognize achievements like:

Most active contributors
Best EA visualization or use case
Teams that eliminated redundancies or risk

Use leaderboards, internal newsletters, and town halls to spotlight contributions.

Step 14 – Expand Scope and Deepen Capabilities

Once the core domains are modeled, expand:

Onboard additional departments or geographies
Introduce advanced capabilities (e.g., scenario planning, cost analysis)
Leverage APIs and automation to reduce manual data entry

Scale thoughtfully, ensuring quality and adoption don’t suffer.

Step 15 – Continuous Improvement and Strategic Feedback Loops

Enterprise architecture is not a one-time project—it evolves with the business. Set up regular feedback and governance loops:

Quarterly reviews with stakeholders
EA council meetings
User feedback surveys

Use these to refine taxonomies, clean up data, and expand the platform’s impact.

Conclusion

Rolling out an EA platform is a journey. With clear goals, committed stakeholders, and the right champions in place, you can transform enterprise architecture into a strategic powerhouse. The results? Better decisions, fewer risks, and faster innovation.

Stay patient, stay transparent, and always align with business value.
