The Unknown Problems of Legacy Systems (The Troubled Child)
P-010
When investigating a legacy enterprise system, we may not know the full extent of the problems we have inherited. Experienced application and system specialists may have retired or departed. Documentation may be incomplete, outdated, or missing. Source programs, data files, and other essential materials may be damaged, corrupted, or unavailable. Hidden dependencies, undocumented business rules, and unexplained system behavior may create additional difficulties.
Can Generative AI help us identify, investigate, and document these unknown problems, while human experts provide the validation, judgment, and authorization necessary to establish reliable findings?
