Quality check must be signed off by whom in TCS?

In the context of TCS and its quality assurance processes, it is essential for both the Black Belt and the Customer to sign off on quality checks. The Black Belt is a trained expert in process improvement methodologies and quality management, ensuring that the project adheres to defined quality standards and methodologies. Their approval signifies that the deliverables meet internal quality requirements.

On the other hand, the Customer's sign-off is crucial as it represents the acceptance of the deliverables from the customer's perspective, indicating that the product or service meets their expectations and requirements. This dual sign-off process ensures a comprehensive quality assurance approach, where both internal metrics and customer satisfaction are taken into account, reinforcing the commitment to delivering high-quality outcomes. Having both parties sign off mitigates the risk of discrepancies between what is provided and what is expected, fostering strong relationships and trust between TCS and its clients.
