history
From Sima Qian's 《史记·留侯世家》 (Western Han): Zhang Liang tells Liu Bang that among his generals only Han Xin is worthy of great responsibility, 独韩信可属大事，当一面, capable of holding one side of the fight alone. The modern form 独当一面 compresses this directly.
usage
Positive, describes professional competence and readiness for autonomous responsibility. Common collocations: 能独当一面, 可以独当一面. Often paired with 培养, 锻炼, 成长为.
