SPC & SQC Programs

SPC & SQC Program Design for Incoming Material and Process Control.

Every quality problem that reaches your customer traces back to a control point that either didn’t exist or wasn’t followed. Statistical Process Control (SPC) and Supplier Quality Control (SQC) programs are how disciplined operations catch variation and defects before they become a shipped product or a failed audit finding. CDR Global Enterprises sets up supplier qualification programs and appropriate on-line statistical sampling for incoming material inspections — including COA criteria and defect calibration standards — that meet both government and customer requirements. This is quality control consulting built on real statistical rigor, not arbitrary sampling rules.

What SPC & SQC Program Work Includes

Who This Is For

Manufacturing facilities and material suppliers across pharmaceutical, food, dietary supplement, cosmetic, and homecare product categories that need defensible, statistically valid incoming inspection and in-process control programs — especially where multiple suppliers or high material variability create risk.

Our Approach

We design SPC and SQC programs around your actual defect history and risk profile, not a one-size-fits-all sampling table. The result is a program your quality team can defend to any auditor and your operations team can actually run day to day.

Why This Matters

Programs built on real statistical process and supplier quality control catch problems at the material and process level — long before they become a finished-product deviation, a customer complaint, or an audit citation. This is one of the highest-leverage investments a facility can make in both product quality and long-term cost reduction, since it prevents defects rather than reacting to them after the fact.

Questions, answered.

What's the difference between SPC and SQC?

SPC (Statistical Process Control) monitors your internal manufacturing process for variation using tools like control charts. SQC (Supplier Quality Control) applies similar statistical discipline to incoming materials from your suppliers. Most facilities need both working together.

Yes — that alignment is one of the most common gaps we resolve. We build COA acceptance criteria that meet regulatory expectations while also satisfying customer-specific quality agreements.

Both. We help design the initial supplier qualification program and can support ongoing supplier performance monitoring and requalification cycles.
