The J-Curve of Change

The J-Curve of Change is a practitioner framework, first published in 2005, describing the characteristic trajectory of organisational performance during technology-driven transformation. It proposes that performance reliably deteriorates following the introduction of change before recovering and surpassing the prior baseline — forming a 'J' shape when plotted against time. The framework identifies three management imperatives for leaders seeking to navigate this period successfully: managing stakeholder expectations, minimising the depth of the performance dip, and ensuring the organisation recovers fully. Originally developed from the author's experience leading major intranet portal implementations at two of the United Kingdom's largest organisations, the model has since been applied widely across change management, project management, healthcare, education, agile methodology, and AI transformation contexts. This paper formalises the framework, situates it within the change management literature, and documents its subsequent adoption and citation across academic and practitioner communities.
