Meet Panday. Compliance, made simple.
Panday is our flagship QMS software platform, purpose built for small and mid size aerospace and defense suppliers, from precision machine shops to Tier 2 through 4 suppliers. It is a complete, audit ready quality management system delivered as Compliance as a Service.
Panday combines our platform with prebuilt AS9100D and IA9100 document templates, audit readiness scoring, and hands on consultant support, helping you navigate the upcoming IA9100 and ISO 9001:2026 transitions without enterprise platform cost or complexity.
Panday's Quality Manager dashboard: action queue, KPIs, and live workflows for an AS9100D + ISO 9001 system. Sample data shown.
Every app, one platform: NCR, CAPA, audits, inspections, SPC, APQP/PPAP, calibration, suppliers, traceability, and dozens more across Quality, Operations, Logistics, and Certification.
A boutique partner, invested in your outcome.
We are a small firm by choice, so the people you meet are the people doing the work. No layers of account managers, no recycled playbooks.
Hands on, not hands off
We work the floor alongside your team, observing real processes, talking to real operators, and shaping systems around how work actually happens.
Practical by design
No bloated binders that gather dust. We build lean, usable documentation your team can follow on a Tuesday morning, not just during an audit.
People first quality culture
Quality only sticks when people own it. We coach teams toward a culture where quality is a shared habit, not a department that polices them.
Built on the belief that quality is human.
Keystone Quality Consulting was founded on a simple conviction: the best quality systems are the ones your team actually uses. After years inside manufacturing floors and audit rooms, we saw the same pattern again and again: elegant documentation that no one followed.
That conviction comes from 15+ years inside aerospace, defense, and high reliability manufacturing, from Raytheon and L3Harris/Stellant Systems to Belden and Smiths Connectors, including guiding a high speed semiconductor ASIC firm to first attempt AS9100D certification and $300K in cost reductions. We bring deep technical rigor in QMS architecture, root cause discipline, and audit readiness, paired with a partnership that earns trust rather than demands it.
Christian's M.S. in Systems Engineering, spanning systems thinking, lean engineering and management, and engineering leadership and capped by an AI powered adaptive traffic control capstone, shapes how Keystone approaches quality: as a system, not a department.
Whether you are standing up a quality program from scratch or rescuing one that lost its way, Keystone is here to help you build systems that endure.
Answers, up front.
What does Keystone Quality Consulting do?
We help small and mid size aerospace and defense manufacturers design, implement, and maintain practical AS9100D, IA9100, and ISO 9001 quality management systems: QMS architecture, SOPs, training, internal audits, and audit preparation.
What is Panday?
Panday is our Compliance as a Service QMS platform: software plus prebuilt AS9100D and IA9100 templates, audit readiness scoring, AI assisted document intelligence, and recurring consultant support, without enterprise platform cost or complexity.
Can you help with the IA9100 transition?
Yes. IA9100 is expected to publish alongside the ISO 9001:2026 revision, followed by a transition window for AS9100D certified suppliers. We provide gap assessments, transition planning, and documentation updates so you stay audit ready through both changes.
Who leads Keystone Quality Consulting?
Founder and Principal Consultant Christian Perez, an ASQ Certified Quality Engineer and AS9100 Rev D / ISO 9001:2015 Lead Auditor with an M.S. in Systems Engineering and 15+ years of aerospace, defense, and high reliability manufacturing quality leadership.
