Scaling LaunchDarkly's feature management platform across an entire organization involves choosing the right implementation model, with three main options: the single project model, one project per product line, and the shared services model. The single project model is easy to implement and suits smaller teams or monolithic structures but can become complex with numerous flags and permissions. The one project per product line model is ideal for organizations using microservices, as it simplifies permissions and limits scope but lacks cross-project dependencies. The shared services model, popular for managing common service dependencies, allows centralized flag management but requires careful handling to avoid complexity, such as not duplicating flags across projects. Each model has its advantages and challenges, and understanding them is crucial for a smooth scale-out process of LaunchDarkly within an organization.
