IBM Bob is positioned as an AI 'Software Development Lifecycle Partner' rather than just a code generator. The post argues that vibe coding — fully autonomous AI-driven development — creates fragmented architectures, technical debt, and loss of human ownership, ultimately slowing enterprise delivery by 19% despite developers feeling faster. The proposed alternative is spec-driven development (SDD), which balances human ownership, agent autonomy, and project trust across four stages: requirements, spec creation, implementation, and verification. IBM Bob supports the entire SDLC including upstream research, shift-left security, and downstream observability. Enterprise-specific features include governance via usage analytics (Bobalytics), token tracking (Bobcoins), application modernization packages for Java, IBM i, and IBM Z platforms, and a planned on-premises deployment option.
