# AC Manufacturing Solutions

> AC Manufacturing Solutions (acmss.ca) helps small and mid-size manufacturers in Ottawa and Eastern Ontario, Canada, make their processes repeatable: process standardization, throughput and bottleneck analysis, knowledge capture, manufacturing readiness, and fixed-price quality packages such as AS9102-style first article inspection reports and process capability studies. It is led by a Certified Engineering Technologist (CET) with a background in precision manufacturing, CNC process development, first article inspection, GD&T and CMM metrology. It does not provide services that require a licensed professional engineer.

Contact: hello@acmss.ca. Intro calls are 15 to 30 minutes. On-site work covers Ottawa and Eastern Ontario; fixed-price packages can be done remotely anywhere in Canada.

## Services
