别再责怪QA了：诊断交付背后隐藏的低效问题
软件交付延迟时，团队常常将责任归咎于QA（质量保证）环节，认为测试拖慢了进度。然而，真正的问题往往隐藏在更早的开发流程中——如需求不清晰、技术债务积累、沟通断层和缺乏自动化测试。本文通过分析实际案例，揭示了这些系统性低效因素，并提出了从根源优化交付流程的策略，帮助团队摆脱“甩锅文化”，实现更顺畅的持续交付。

A JAX developer found that array lookups on CPU-hosted data took over a second each, because arrays created with the `default_device` context manager are uncommitted to that device. Using `jax.device_put` to explicitly commit the array to the CPU reduced lookup times from ~1.2s to under 0.0002s, fixing a severe bottleneck in LLM training data loading.
