Could another engineer make this release again?
Participants receive an invented release report showing successful deployment alongside an incomplete construction account. They identify which claim the operating result supports and which materials another engineer would need before asserting reproducibility. A second stage introduces a choice between reconstruction and retirement after replacement, with limited capacity and delayed features. Groups must describe the service decision behind retirement instead of simply removing difficult items from an inventory. The output is a management account that distinguishes running, reconstructing and validating software, with the costs of correction retained. This is a proposed learning format, not a delivered engagement or technical certification. It uses fictional artefacts and requests no proprietary source, credentials or internal build instructions. Participants retain the roles of qualified engineering and business owners rather than treating the exercise as permission to alter a live system. The purpose is to practise an assurance statement whose meaning remains accurate when the original release team is no longer available to explain it.
