Unverified修复需求阶段的错误比修复编码阶段的错误成本低10倍以上78% similarUnverifiedIBM和NASA的研究数据显示，在需求阶段发现的错误与在编码或测试阶段修复同一错误的成本差距可达10到100倍76% similarVerifiedResearch shows that the cost of fixing errors discovered in the requirements and design phases is only 1/10 to 1/100 of the cost at the coding phase.75% similarUnverifiedThe more detailed the answers provided to the AI during the requirements analysis phase, the lower the probability of bugs in the final product; the cost of fixing errors found in the requirements phase is only 1/10 to 1/100 of the cost of finding the same type of error in the coding phase.71% similarUnverifiedIn Barry Boehm's 1981 cost estimation model, he noted that defects introduced during the requirements phase, if not discovered until the coding phase, increase repair costs by 5–10 times, and costs can increase by 100 times if discovered after deployment.69% similar
