A consortium of academic libraries is developing a new inter-library loan system, strictly adhering to the interoperability standards defined in ISO 10160:2015. Mid-project, a national regulatory body issues a directive mandating that all new information exchange systems must also demonstrate backward compatibility with a widely adopted, albeit less efficient, legacy protocol for a period of five years. The project team, initially focused solely on ISO 10160:2015 compliance, must now re-evaluate their development roadmap and technical implementation strategy to accommodate this new requirement without compromising the core ISO 10160:2015 functionalities. Which behavioral competency is most critical for the project team to effectively navigate this unforeseen strategic pivot and ensure continued project success?
