Drinking your own champagne is crucial for developer productivity, faster feedback loops, and creating better products in 2024. It creates empathy by understanding user needs and challenges, reducing friction and developer toil by uncovering pain points and addressing them immediately. It helps measure success and create cross-functional alignment by aligning the development process with business goals and ensuring teams work together towards common objectives. This approach starts with the culture, fostering a philosophy of continuous improvement through onboarding, best practices, and leveraging tools to spread knowledge within the organization. By using their own software internally, organizations can gain valuable insights into user needs, improve products, and deliver high-quality solutions that meet the needs of both internal developers and external users.
