Com minha experiência do setor da qualidade, após a etapas da escolha das empresas parceiras e assinados os contratos seria apresentado em reunião presencial os padrões vigentes pré acordados com o cliente, seria capacitado os times das empresas parceiras através de cursos, work shops, OJT e posteriormente auditorias técnicas periódicas, a fim de, mensurar os níveis das instalações e através de dados estatísticos extrairia os ofensores e times com piores performances apresentaria um plano de ajustes e ou re capacitação, para nivelar todos envolvidos na implantação .

El seguimiento activo y el trato dinámico con el proveedor es de suma importancia. Tambien es necesario que el proveedor no vea a los inspectores como enemigos sino como colaboradores que le ayudaran a alinearse a los estandares. Por otro lado estan las charlas continuas donde se deben detectar los puntos donde ocurren flaquezas y a partir de eso se deben establecer mayoresfrecuencias de control. Una estrategia a nivel contractual es poner los pagos atados a la certificación dwe los inspectores de los requisitos de estandares a cumplir

Establish clear communication and expectations, monitor performance, and enforce accountability through detailed contracts, regular communication, on-site inspections, and documented quality control processes.

To ensure subcontractors consistently meet industry standards, start with clear agreements that define quality expectations. Regular audits and real-time monitoring help catch issues early. Keep communication transparent and structured, and provide ongoing training to align everyone. Use KPIs and performance reviews to maintain accountability. Most importantly, make compliance part of the company culture—when everyone understands its value, standards aren’t just followed, they become a natural part of how business is done.

In my experience, the main problem is when the subcontractor misunderstands the engineering, specifications, and technical documents or even doesn't use them. Therefore to ensure that the works meet the standards, ask them if they understand the requirements and be sure that they have read the technical documents after that if they have no doubts, overseeing will be easy and the work will meet the standards.
