Reliability programs are crucial for organizations to proactively manage and improve system resiliency and availability, and they should be built around four key pillars: leadership and strategy, clear ownership and handoffs, measurement and metrics, and processes and policies. These programs require more than just technology; they necessitate organizational coordination and clear strategies, goals, and accountability. Leadership buy-in, clearly defined responsibilities, and the ability to measure progress against business-relevant metrics are essential for success. Establishing consistent and robust processes and policies helps ensure ongoing compliance and improvement. Gremlin, a company specializing in reliability, advocates for these principles and offers tools and resources to help organizations uncover and address reliability risks before they impact users, including a free trial of their platform to identify hidden system risks.
