Just as physical buildings follow carefully designed architectural blueprints, conceiving stable, safe structures and hopefully pleasing to the eye, every business needs to map out their unseen data into a ‘blueprint’ that encompasses their entire organization.
That’s what architects do: they map out and design organizations. Unfortunately, there’s no all-encompassing definition of Enterprise Architecture vs. Solution Architecture that everyone agrees on.
Ask Google, and you’ll find many interpretations. Look into online forums, and you’ll find people disagreeing vehemently on semantics, and with good reason. Each unique organization needs to develop a method and definition of architecture that best suits its purpose.
Enterprise Architecture and Solution Architecture operate in a hierarchical relationship. Enterprise Architecture establishes the overarching strategic framework and guidelines, while Solution Architecture interprets and applies these directives to create project-specific architectures.
Understanding the differences between Enterprise Architecture vs. Solution Architecture is essential if you’re to map out your organization correctly.
In this article, we’ll uncover in more detail the differences between these two disciplines and the role each plays in an organization.
As the name suggests, Enterprise Architecture (EA) examines the entire enterprise. It helps shape the organization and can involve defining the business properties, capabilities, people, and potential future outcomes. Often, this starts by gathering data and mapping it out to show the relationships between all the different entities of an organization.
Enterprise Architecture can help an organization maintain its everyday applications and equip it to manage change. It works with various architectures, including application, business, data, and infrastructure.
Solution Architecture is more tactical and deals with addressing specific business needs. Solution Architecture may seek to solve existing business challenges or propose technical solutions to new problems. It defines how to structure a solution and make it happen within the context of an enterprise’s architecture.
Enterprise Architects usually work within the four areas noted above. Depending on organizational needs, work could include any of the following domains of Enterprise Architecture:
Strong knowledge of architectural frameworks: An enterprise architect needs a broad knowledge of frameworks to deliver effective change.
Problem-solving: To identify and address organizational issues, architects should be proficient in troubleshooting and technical analysis.
Solution management: An architect should be engaged throughout each stage of the solution implementation process.
Conflict resolution: As structures and systems are implemented, disagreements will inevitably occur. It’s the job of the architect to address these conflicts.
Identify potential risks to IT systems.
Create and oversee the execution of strategies.
Utilize an Enterprise Architecture tool to achieve key outcomes.
Facilitate digital transformation by introducing new technological solutions.
Carry out gap analysis to ensure that business objectives are being met.
Create a center of excellence to provide knowledge and expertise.
An Enterprise Architect should be forward-thinking. This means staying up to date on the latest technologies and architectures. They should be eager to propel their organization to the next stage of transformation.
For example, let’s say company XYZ wants to exploit the possibilities inherent in AI technology - for instance, mapping customer engagement patterns to predict what they might purchase next.
The Enterprise Architect could map how XYZ uses AI today and what steps should happen to reach its future goals. They could note which changes should be made to the infrastructure by adding applications, processes, skills, and teams, assessing risks, and predicting the scenarios resulting from these future decisions.
Enterprise Architects today must understand their businesses and the qualities their stakeholders care about.

Solution Architects develop and integrate solutions and processes based on the enterprise’s needs. How they go about this depends on the individual’s background and how the organization defines its solution architecture.
Depending on the situation and after being presented with a business challenge, Solution Architects is focused on current technologies available and what needs to be developed to allow the business to meet specific business or project objectives.
The Solution Architect’s job could include studying all aspects of the solution, including budget, technology, risk, time, quality, etc. They would find the limitations and restrictions that impact the project and then plan their solution around these.
For example, a Solution Architect might be tasked with building a solution that deals with knowledge management in the company. There are many different ways to design and build this over time.
As they build, the Solution Architecture ensures it’s functionally suitable, has security capabilities, is reliable, and is available to people across the organization. Sometimes, they will map the qualities of the solution, creating a clear overview of the process.
Enterprise Architecture helps companies plan and execute the future by supporting their daily decisions. EA provides the overview for decision-makers to understand what’s happening across their organization.
Depending on the organizational need, the value of enterprise architecture can be seen in: architecture adds value to:

A well-built architecture ensures that solutions are delivered within budget, on time, and solve the problem as promised.
Solution Architects add value by planning and streamlining solutions. They understand the value proposition, solution components, scope, and pricing model. They make sure that the solutions match the corporate strategy and meet stakeholders’ requirements.
Here are some examples that a Solution Architect could offer to software solutions:
But what is the difference between Enterprise Architecture vs Solution Architecture? The table below gives a general overview.
Ask someone to explain the difference between a Solution Architect vs an Enterprise Architect, and the conflicting answers vary. This article has tried to outline some key differences between roles and the two architectural disciplines. Ultimately, the work of both Enterprise and Solution Architects at different organizational levels drives toward the same overall objectives of furthering core business outcomes rather than documentation or data management.
