Dispatch & Utilization: Optimize technician deployment strategies to meet strict Availability timelines and minimize Liquidated Damages (LDs)
Disciplined Problem Solving & Quality
Root Cause Analysis (RCA): Implement and enforce a disciplined approach to field issues using industry-standard methodologies such a 8D, Fishbone (Ishikawa), and 5-Whys.
Continuous Improvement: Feed field data back to the R&D and Manufacturing teams to improve cell and module design, specifically targeting recurring failure modules. 
Reporting: Develop and maintain executive dashboards tracking fleet health, warranty spend, and adherence to performance guarantees.
