# Criteria for Abandoning Projects Due to Tech Shifts

> **Open question:** What criteria should trigger abandoning a project due to technology shifts?

The [[entity-lloyds-banking-group]] example mentions recognizing that rapid changes in technology can warrant abandoning ongoing projects to switch to new use cases. The text does not detail the specific financial or technical thresholds (e.g., sunk-cost vs. opportunity-cost formulas) used to trigger such a pivot.

**Resolution path:** Define explicit thresholds and fold them into the 'regular reviews' mechanism of the [[framework-three-portfolio-mechanisms]]. Relates to [[concept-genai-control-tower]] and the broader sunk-cost/opportunity-cost tension in portfolio rebalancing.
