Goals: 5 Patentable Ideas 4 Projects transferred to Engineering 3 direct visits with customer/field trip Bring innovation culture throughout the company

Focus Agriculture – Focusing on new products for existing markets and customers. Making life simpler for the farmer or tree care specialist. Rail/Transportation – Product roll up from around the world and a renewed focus on an existing and growing market. California recently invested $8m into a proposed high speed rail corridor, and of course the Hyperloop. Big Data Collection – Data will be a play, but how it’s collected, stored, and used is up for debate. Where can we play? Sealing Technologies – Develop new techniques to bolster our already outstanding offering. Innovation Team Overview

Execution Education - The team worked hard to educate themselves on what innovation is. Attended seminars and workshops for best practices, and studied the successes, and failures, of several high profile innovation garages. Investigation - The team spent time with the PLP sales group, both internal and external, as well as traveling to meet with customers and industry professionals, learning more about the needs of our different markets. 70/20/10 - This rule applies to the team’s approach to products and how they spend their “bandwidth”. It helps to bring a focus to the bigger picture for the group. Innovation Team Overview
