In the intricate landscape of complex projects, architecture serves as the foundation upon which success is built. Well-designed architecture guarantees scalability, performance, and maintainability. Poorly designed architecture opens up major challenges and costly rework later. As a protection against these risks, architectural review is an important development lifecycle stage. In this article, we show the relevance of architects for project development by describing how an experienced architect contributes valuable insight into problem identification, performance optimization, and assurance of long-term project success.
