How to Create an Architectural Design for a Reusable PoC

This article explores the benefits of creating reusable designs, including time and cost savings. Learn about system usage scenarios, solution evolution, documentation, and SEI/TOGAF frameworks for revealing key features.


In the early stages of any product development, a Proof of Concept (PoC) serves a purpose beyond mere testing. As a customer, it is essential to aim for a reusable PoC to save time and money in the future. This article will guide you through the process of creating an architectural design for a reusable PoC, highlighting its importance as an early investment that provides a comprehensive view of the project from the start.

Defining the PoC

A PoC goes beyond testing functionality; it lays the groundwork for future development. By focusing on reusability, you can maximize efficiency and cost-effectiveness. Designing an architecture that allows for expansion and scalability is crucial to achieve long-term success.

Architectural Design for Projects of All Sizes

Architectural design is not exclusive to massive systems. Even smaller projects can benefit greatly from a well-thought-out architecture. It ensures consistency, modularity, and maintainability, making future enhancements and modifications easier to implement.

Revealing Key Features with SEI/TOGAF

SEI/TOGAF frameworks offer valuable guidance for identifying and prioritizing key features. By leveraging these frameworks, you can define the most critical functionalities, quality attributes, and solution evolution to align with your business goals effectively. To effectively reveal the key features of your PoC, leveraging frameworks like SEI/TOGAF can provide valuable insights and a structured approach. Here's how you can make the most of these frameworks:

  • Conduct a Workshop: Gather stakeholders, architects, and subject matter experts for a collaborative workshop. This session helps in identifying and understanding the business goals, user requirements, and technical constraints. It allows for open discussions and brainstorming to shape the direction of your PoC.
  • Discovery Phase: Perform an in-depth analysis of your target market, customer needs, and existing solutions. Conduct market research, competitor analysis, and user interviews to gain a comprehensive understanding of the landscape. This step helps you identify unique selling points, competitive advantages, and potential gaps to address in your PoC.
  • Feature Comparison: Compare the features and functionalities of your PoC with those offered by competitors in the market. This analysis helps you identify areas where you can differentiate your product and deliver enhanced value to your customers. Prioritize the features based on their significance and potential impact on your target audience.
  • Define Priorities: With the insights gathered from the workshop, discovery phase, and feature comparison, establish a clear set of priorities. Consider the business value, feasibility, and technical complexity of each feature. This prioritization allows you to focus on the most critical aspects of your PoC, ensuring that your efforts align with your overall goals.
  • Architectural Alignment: While revealing key features, pay close attention to how they align with your chosen architecture. Ensure that the architectural design supports the identified features, scalability, performance, and future growth. A well-aligned architecture provides a strong foundation for your PoC and facilitates seamless integration of additional functionalities.
By following these steps within the SEI/TOGAF framework, you can effectively reveal the key features of your PoC. This approach brings clarity to your development process, enhances decision-making, and increases the likelihood of creating a successful and reusable PoC.

Documentation as a Must

Comprehensive documentation plays a vital role in the success of a reusable PoC. Beyond satisfying the needs of investors, proper documentation saves time and money during resource hiring and future development efforts. It serves as a reference point and ensures smooth collaboration among team members.

To ensure the effectiveness and reusability of your PoC architecture, it is essential to create comprehensive documentation. Here are some key documents that should be included:

  • Solution Design Document: This document outlines critical system elements, such as error handling mechanisms, communication protocols, database structure, and how the solution aligns with the specific business needs. It serves as a blueprint for the development team and provides a clear understanding of the architecture's key components.
  • Set of System Usage Scenarios: These scenarios describe how the provided architecture aligns with the project goals and requirements. They provide concrete examples of how different user interactions and workflows can be supported by the architecture, ensuring that it effectively addresses the intended use cases.
  • Prioritized Quality Attributes: A set of prioritized quality attributes serves as a reference for evaluating the architecture's performance, scalability, security, and other essential characteristics. These attributes provide a framework for making informed decisions during the development process and help prioritize future features or improvements.
  • Description of System Evolution: The most critical parts of the system should be described in terms of their expected evolution. This includes outlining potential changes or enhancements that may be required in the future to adapt to evolving business needs or technological advancements. By having a clear vision of the system's evolution, you can ensure that the architecture remains flexible and scalable.
By creating these documentation artifacts, you establish a solid foundation for your reusable PoC architecture. They not only provide guidance to the development team but also serve as valuable references for future enhancements and decision-making processes.


Creating an architectural design for a reusable PoC is a strategic investment that pays dividends throughout the development process. It enables you to foresee the big picture, align the system's structure with your objectives, and increase functionality without major overhauls. By incorporating essential functionalities like authorization, logging, error handling, and scaling from the early stages, you can prevent potential issues during a successful launch. Remember, a well-designed PoC should be efficient, aligned with your business goals, and adaptable to change.
