At Amazon, we are always looking for what we can do better. Our Amazon Customer Excellence Systems (ACES) teams help drive that change. Finance ACES Black Belts apply Lean Six Sigma problem-solving skills to continuously improve Amazon processes, align them with customer requirements, and deliver positive impacts in controllership and cost savings. Black Belts apply a mix of quantitative and leadership skills to identify areas of improvement and prioritize resources. Black Belts drive the culture of self-inspection and continuous improvement where acting on fact and eliminating defects and waste is the norm. Black Belts contribute to the Finance Operations Production System by leading and mentoring projects, conducting training events, developing materials, and providing metrics on improvements and performance of the program. Black Belts have a documented track record of leading, building rapport, and mentoring process improvement teams consisting of members of all levels and functions, without formal reporting relationships. Finance ACES Black Belts demonstrate Amazon Leadership Principles.
