A service catalog is a centralized platform that lists and manages all the software services available within an organization, providing a standardized format for discovering and utilizing them. This tool empowers developers to take the lead in gathering resources needed to create products, reduces IT support burdens, and promotes quality through standardization. By using a service catalog, organizations can improve governance, documentation, discoverability, and systemic benefits such as proactive development and cost optimization. However, implementing a service catalog also comes with challenges, including adoption, outdated documentation, sprawl, and requiring leadership buy-in and a dedicated team to maintain its success.
