Seisa Transfer Model

Case Study



Seisa Medical was challenged to increase production output of an implantable device by 50% within just four months.

Seisa’s customer — a large multinational medical device player — introduced an improved version of their Class III device to incredibly strong market demand. As a result, Seisa Medical was challenged to significantly increase production output of the implantable device while sustaining quality levels and operational KPIs. The product required a highly specialized skill set for operator certification. Historical data indicated several thousand people would need to be recruited for intensive training before final selection of the few hundred required. All this needed to be done within a four-month period.


watermarkSeisa created a customized solution, including investment to accelerate its recruiting cycle while leveraging an existing, robust training process. A cross-functional team was formed with Seisa’s customer to define project deliverables such as headcount, training, and layout configuration changes in compliance with regulatory requirements. The solution was supported with a milestone-based tracker with specific tasks and timelines to accomplish the required increase with no delays and without compromising quality or delivery. Using historical training data, Seisa implemented a plan to recruit and compensate more than 5,000 people to undergo Seisa’s rigorous training and certification program. Ultimately Seisa was successful in yielding the several hundred highly skilled operators needed to support the increased output requirements. Seisa’s success resulted from its robust recruiting and training practices, its investment in its people, and its experience in manufacturing Class III products.

watermarkBy leveraging Seisa’s customized solution, including advanced recruiting and training methods, the customer gained significant market share and increased sales on a high margin product line that is still growing.


Project Transfer


Seisa helps customer with product transfer for higher profitability.

A small division of a large healthcare company approached Seisa for assistance with a portfolio of disposable products. The customer was facing profitability challenges and growing concerns related to regulatory compliance. The product mix included a variety of sterile single-use devices and the customer possessed limited experience with production transfers.

watermarkSeisa proposed a tailored solution to support the customer’s plan to drastically reduce the product mix, while bringing the product into Seisa’s established medical device assembly facility, taking over turnkey supply chain management and leveraging Seisa’s fully compliant Quality Management System (QMS). Seisa mapped the customer’s QMS and adapted a customized and fully-compliant quality plan to support the customer’s refined product portfolio.

Following Seisa’s standardized transfer process, a special team lead the review of all customer requirements and built a documented transfer plan. The Seisa transfer manager conducted daily project reviews with the extended team including both Seisa and customer representatives. The cross-functional transfer team included subject matter expertise in all relevant functional areas and addressed specific manufacturing techniques for bonding, mechanical assembly, ultrasonic welding, and plastics processing.


  • The Seisa team completed the transfer plan within 4 months, 2 months ahead of plan
  • Made customer’s implantable device profitable by reducing overhead and improving inventory management
  • Alleviated customer’s quality and regulatory concerns by producing device under Seisa’s proven QMS
  • Seisa continues to deliver a high-quality product on time and at a lower cost than the customer’s previous process
