Advancing Strategic Alliance Commitment Under Sustainability Conditions: A Process‐Based Benefit–Risk Framework for NPD Alliances

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Strategic alliances frequently fail not because they lack value, but because firms struggle to sustain commitment over time. This challenge is especially salient in sustainability‐oriented and new product development (NPD) contexts, where interorganizational collaboration is widely promoted yet difficult to maintain.
