This year, we took an interim engagement survey that collected our associates’ feedback in similarly themed areas that are required to build a high- trust organization. Of particular note, our high-strength composites that enable lightweighting and barrier additives that reduce material requirements and increase shelf life both performed exceptionally well. The high level of attention, engagement and collaboration among member CEOs has been instrumental in AEPW’s very first year.
