We found that a project that followed IID since inception provided substantially better bug-fixing responsiveness and found bugs earlier in the development lifecycle than existing projects that migrated to IID. IID practices also supported managerial decisions that lead to on-time & on-budget delivery.unknown10.1007/978-3-642-13054-0_21
