A modular architecture linked to development teams can lead to significant improvements in development cost, cycle time, and engineering effectiveness. By decoupling teams and domains, organizations can achieve better results and capitalize on new opportunities. However, implementing a modular architecture requires upfront and ongoing effort, and it is important to avoid blindly replicating what has worked for others. Each organization's situation is unique, and careful consideration and understanding of their own landscape is necessary. The modular architecture should be intrinsically linked to teams, ensuring empathy, autonomy, and effective communication. Additionally, investment in technical leadership and robust guardrails and guidelines can help mitigate challenges and ensure success. The benefits of a modular architecture include reduced startup costs, improved engineering effectiveness, faster cycle time, and the ability to introduce new features more quickly. However, it is important to address architectural oversight, manage dependencies, and avoid bloat. The success of a modular architecture relies on factors such as technical debt management, communication, and collaboration between domain teams and consumer teams. It is also crucial to consider external factors and limitations when implementing a modular architecture. The results of implementing a modular architecture can be measured through metrics such as development time, cycle time, and adoption rates. A successful modular architecture requires investment in technical leadership, a focus on improving developer experience, clear ownership of domains, and the ability to solve central problems. A platform team can play a crucial role in providing guidance, reducing friction, and enabling efficient bootstrapping for domain teams. However, it is important to balance autonomy with the need for common frameworks and guidelines. Overall, a modular architecture can lead to significant improvements in development outcomes if implemented effectively. The organization implemented a topological structure that supported modularity and focused on developer experience to support modularity. They shifted from building functionality solely for the benefit of the market to a more holistic mission of meeting the needs of its consumers. The restructuring allowed for better communication and collaboration between autonomous development teams. The organization encountered problems when trying to reuse domains in different markets, which led to market feature disparity and cross-team contributions. They also faced issues with tightly coupled code and a lack of cohesion, resulting in technical debt and decreased value delivery. The organization recognized the signs of deterioration and implemented a modular architecture, but faced challenges in understanding how to achieve the expected benefits. A modular architecture can provide optionality through interchangeability and reuse interfaces, as well as abstraction of complexity through appropriate encapsulation of functionality. This article discusses the challenges faced by large enterprise mobile app development teams and how a modular architecture can address these issues. The article presents different scenarios and domains where modularity can be implemented to achieve better software delivery performance. The focus is on improving the developer experience and recognizing the signs that indicate the need for modularity. The results of implementing a modular architecture are discussed, along with limitations and potential benefits.
