Quality Engineering, Consulting & Auditing

Consulting, Engineering and Supplier Development

Our services are based on 30+ years of industrial knowledge and experience supporting suppliers and OEMs in the most exacting industries. TRIGO has conducted thousands of tailored projects with local experts all over the world. We help ensure your products meet required customer timeline and quality targets and help you to stand out from your competition.

Advanced Phase and Launch Services (including APQP, MLA, PPAP, and Safe Launch)

Whether you need to integrate and coordinate multiple suppliers, or just need external support to manage your own activities, TRIGO will establish the right team of subject matter experts, control your deliverables and report all readiness issues. We provide full follow-up and make sure issues are solved on time.



Management System Development and 
Implementation (QMS, MSS)

TRIGO helps you implement and maintain a proper management system so you can exceed industry and customer-specific standards. TRIGO experts offer consulting, auditing and training to guarantee that your organization is ready for certification and has effectively adopted the expected management system model elements.


Capacity and Constraint Management

Ramp-up phases or increased market demand can result in supply chain constraint. TRIGO can help you minimize the resulting investment needs by providing a comprehensive assessment. This may include a full Capacity Audit (Run@Rate) and can identify/eliminate constraint as well as increase potential throughput and Overall Equipment Efficiency (OEE) to meet your market demand and avoid significant investment in machinery or tooling.

Lean Management

TRIGO can increase the performance of your critical business processes based on the principles of Lean and Six Sigma. KPIs targeted for improvement can include FTQ, ppm, cycle times, OEE, and more.

We apply pull system, warehouse leveling, cycle time alignment and reduction, internal fall-out rate reduction, First Time Quality (Direct Run) increase, SMED, JIT/JIS method, Kanban, VSM, Line balancing, 5S, TPM, and more.  

Change Management & Business Transfer Coordination

You or your suppliers are faced with continuous design or process changes for improvement or correction of quality problems. These can be permanent, or an interim solution or deviation approval to maintain smooth production and delivery. TRIGO experts can help you successfully implement changes, including Business Transfer coordination. This may be initiated by the supplier (production transfer) or by the customer based on risk (re-sourcing).


Supplier Monitoring

Whether you are you facing long term issues with your supplier or need someone to be your eyes and ears during a crisis, TRIGO experts can deploy to a supplier site on your behalf. We can monitor performance of: production, capacity, efficiency, yield / direct run, OEE, throughput, warehouse status, internal fallout rate, management issues, and HR issues.

Quality Incident and Claim Management / Problem Solving

Fixing quality, delivery or material handling issues promptly is key in serial production or during product and process development in order to avoid spills and repetitive issues that already jeopardize smooth production and delivery. Problems need to be managed simultaneously, whether internal, external, upstream or downstream in your supply chain. TRIGO quality experts are ready to manage your issues comprehensively and solve them quickly.

Exit Management

TRIGO Exit Management (CS3 / CSL3) is an effective method of eliminating Controlled Shipping (CS1 / CS2 or CSL1 / CSL2). Some OEMs may use other terminology or combine with systematic and comprehensive problem solving and reporting (such as Q-Help 2 / Q-Help 3, for example). 

Exit Management can be used during Early Production Containment (or Safe Launch), where monitoring and guaranteed exit criteria are necessary.

Top Critical Supplier Management

You may have suppliers causing permanent quality or delivery disruptions, shipping parts with repeating failures impacting your production or generating field warranty issues. Or perhaps you are a supplier listed among the most critical at your customer. In either case, TRIGO is your partner to identify those multiplied problems and root-causes and bring your organization back from a crisis state to a normal state.



Potential Supplier Assessment / New Supplier Qualification

In the early phase of a new project, manufacturers need to identify and assess new suppliers. Potential new suppliers need to comply to customer requirements. TRIGO’s experienced auditors and global geographical footprint offer full service solutions to address these needs.


TRIGO services include not only the process or quality system, but comprehensive assessment of supplier readiness and capability of technology, management, product development, resources, logistics and project management. TRIGO adapts customer and industry requirements, and develops the supplier after the audit to meet customer expectations during APQP and further in serial phase.

Management System Audits (QMS, MSS)

In industrial supply chains, Tier 1 and Tier 2 suppliers are expected to have a 3rd Party Certification by an industrial-specific Management System model (a QMS or MSS). 

TRIGO subject matter experts are ready to conduct audits on your behalf as an outsourced 1st Party, or at a supplier site as a 2nd Party. TRIGO guarantees high-level methodology with full compliance of the original standards and models. If gaps or non-conformities are identified, TRIGO offers support in Corrective Action development and implementation.

Process Audits

You may need to assess your own manufacturing, logistics or service processes (1st Party Audit) or you may need resources to conduct process audits at your suppliers (2nd Party Audits). Audits typically focus on quality processes in manufacturing, logistics and other linked processes, but they can focus on technology and commodity specific requirements as well.


TRIGO’s experienced auditors follow standard methodologies by preparing, conducting and following up quality or technological process audits.

Special Assessments

TRIGO is able to assess your entity / plant, or your suppliers’ site based on any tailored requirements or scope. Examples include logistic audits, MMOGLE, warehouse assessments, or capacity audits (like Run@Rate) in the manufacturing sector. TRIGO has developed its own service chain auditing system that is similar to that typically applied in the retail sector (i.e. Mystery Shopping).

TRIGO has the capability and resources to develop audit methods for you, digitized and fine-tuned to your requirements with further implementation. Full integration and long-term application support is guaranteed by TRIGO.
