“I was apprehensive at first of trying predictive procurement. But when I saw how easy it was for our suppliers and how fast it created a business impact, going predictive with Arkestro became a no-brainer.”

David Schultz, VP, Chief Supply Chain Executive at Westfall Technik

The Challenge

Streamlining sourcing stressors

Westfall molds hundreds of millions of parts at multiple US locations per year that requires tens of millions of pounds of different plastic resins. Sourcing for specific products to make their proprietary blends was costly and slow. They needed to streamline their procurement process – quickly.

Immediate supplier savings

Within 72 hours, Westfall saw an 18% savings with an incumbent supplier who had previously assured that, “I am giving you my best price.” Arkestro ingested internal company data leveraging Arkestro’s machine learning capabilities and predictive models to simulate the supplier’s quotes before even reaching out to the supplier. They were no longer asking for a quote but suggesting an offer to their suppliers.


Westfall Technik is a global contract manufacturing company who primarily molds plastic parts on demand for more than 250 different companies. Over the past 5 years, Westfall Technik has built an impressive platform through the acquisition of over 15 companies and has seen significant organic growth through their global customers base.

The series of acquisitions made it a challenge to integrate different datasets that weren’t fully accurate or updated to the current state. While this data wasn’t the best quality – there was a lot of it – which meant really important insights were difficult to uncover and even when found, often too late.


Once David introduced the concept of PPO to his CIO and showed that there was no software to install or learn, his team was on board. The team was impressed with how highly intuitive Arkestro was, and how they didn’t have to dig through a dashboard or pull up pivot tables to know if they were getting the right quoted price from the best supplier.

“With PPO, Westfall easily accessed and enriched internal historical data with Arkestro’s predictive models and then augmented these simulations using external real-time market data. Its artificial intelligence and machine learning capabilities allow the platform to learn from the new data and resulting analytics, ensuring the most current and precise information.”


Arkestro has helped to strengthen Westfall Technik’s relationships with suppliers and eliminated quote fatigue by allowing decisions to be made in a fraction of the time. Suppliers also appreciate being told how far they are from the leading offer, this transparency means they can better target their offers on the parts of Westfall’s business they are most interested in.

“As the process tracks toward an optimal commercial outcome, Westfall’s procurement team gets notified with recommendations for award allocation that takes into account the holistic nature of the supplier relationship, commercial history, and even factors like supplier risk and operational performance. What was remarkable to us was that in Arkestro, this process typically takes days, not weeks or months”



With the impressive results experienced thus far, David is excited for the future. He estimates that Westfall is only using one quarter of the capabilities of PPO, and is focused on greatly expanding the use of the platform across all Westfall operations.

“PPO allows Westfall to get the best pricing from preferred suppliers on favorable terms more frequently. That’s a great value proposition from my vantage point.”
