DevOps practices can significantly enhance how application teams deliver business value, but the misuse of antipatterns—such as focusing too much on short-term goals and tools without considering people and processes—can lead to poor results. Antipatterns include unscalable team structures, insufficient "shift-left" practices for testing and governance, and overemphasis on tools rather than team dynamics. Addressing these issues involves using cloud-native strategies, integrating security and governance early into continuous integration processes, and fostering effective communication and collaboration within teams. GitHub provides solutions like leveraging declarative patterns, integrating testing tools with code for early quality control, and using frameworks like SPACE to measure productivity and happiness. By overcoming these antipatterns, organizations can improve team success, productivity, and satisfaction while delivering business value more effectively.
