The Second-System Pit of Failure

The second-system effect — where teams rebuilding a successful system add every feature they previously held back — remains one of the most persistent pathologies in product development. If Coatta and Smith have identified new patterns or mechanisms beyond Brooks's original formulation, this could be valuable for the library's craft section. The title suggests they frame it as a 'pit of failure' rather than just an effect, which may offer practical insights for product leaders about how second systems actually fail and how to avoid the trap. Without the abstract, the evaluation depends on whether this updates Brooks with contemporary examples or offers new theoretical insight into why teams reliably make these mistakes.
