A thorough discovery process should define a clear scope, specific goals, and measurable success metrics. Confirm that the partner follows compliance and security best practices, including ISO and SOC certifications and adherence to privacy standards. Effective collaboration requires agile delivery with transparent communication, frequent iteration reviews, and structured sprint planning.
