Both types of documents are important for effective communication and decision-making during software development. KDD captures any significant decision made during the software development process, while an ADD specifically captures decisions related to software architecture itself. The purpose of a KDD is to ensure that important decisions are documented and communicated effectively to stakeholders.īoth Key Design Decision (KDD) and Architecture Design Decision (ADD) capture important decisions related to software architecture. It outlines the context of the decision, the decision itself, and the reasoning behind the decision. Key Design Decision (KDD): A KDD is a document that captures a significant decision that has been made during the software development process. ![]() The purpose of an ADD is to ensure that software architecture decisions are well-informed, documented, and effectively communicated to stakeholders. Architecture Design Decision (ADD): This document outlines strategic, expensive, critical, large-scale, or risky architectural decisions, along with their rationales.It can be included as part of the Solution Architecture Document (SAD), or it can be a separate document known as the Technical Design Document (TDD). This document is typically created by software developers, system architects, or engineers and serves as a reference for the development, testing, and maintenance of the system or component. Technical Design Document (TDD): The Final Technical Detailed Description of Design and Implementation provides a comprehensive technical overview of a system or component.The SAD is created by the solution architect, who typically has expertise in designing solutions for complex business problems. It provides a detailed description of the solution's architecture, including its hardware, software, and infrastructure components, as well as the data and business processes involved. Solution Architecture Document (SAD): The purpose of this document is to describe the design of a specific solution to a problem or requirement.It defines the purpose, scope, key components, interfaces, data model, technology stack, scalability, and performance considerations of the system. High-Level Design (HLD): This document outlines the system architecture and design at a high level.While there are plenty of different types of documentation that can be created, let's start with the basics that can be used for any project. Software projects require various types of architectural documentation to ensure that the system design and implementation are well understood and properly communicated to stakeholders. This post provides some basics that clarify what documentation to use and when. This is why architectural documentation is important: it helps create a common understanding of the solution behind the system for all stakeholders. ![]() While the code can show how the system works, it cannot explain the goals of the system or the story behind architectural decisions and options, nor can it explain how different parts of the system relate to each other. ![]() In "agile" teams, there is often a belief that software architecture documentation is unnecessary because "the code documents the system." However, this statement only tells half the story.
