  The long lifetime and the evolving nature of industrial products make them
subject to technical debt at different levels. Despite multiple years of
research on technical debt management, our industrial experience shows that
introducing systematic technical debt management in a large-scale company is
very challenging. To identify the challenges, we provide a conceptual framework
for holistic debt management across the product development value stream, which
takes multiple categories of debt and their interplays into account.We use this
framework to identify multiple challenges that are still open to be explored by
the research community. Due to the practical nature of technical debt
management, we believe this paper can guide the research community on the needs
of industry for the effective application of technical debt management in
practice.
