Frequently Asked Questions

What is ISO 9001?

ISO 9001:2015 is the international standard for quality management systems applicable to any organization regardless of size or industry. It is based on seven quality management principles: customer focus, leadership, engagement of people, process approach, improvement, evidence-based decision making, and relationship management.

What is a gap analysis for ISO 9001?

A gap analysis compares your current QMS against ISO 9001:2015 requirements to identify where you fully comply, partially comply, or have gaps. It is typically the first step before certification and helps prioritize implementation efforts. This checklist provides a systematic way to perform that assessment.

How is ISO 9001:2015 structured?

ISO 9001:2015 follows the High Level Structure (HLS) with 10 clauses. Clauses 1-3 are introductory. Clauses 4-10 contain the requirements: Context of the Organization (4), Leadership (5), Planning (6), Support (7), Operation (8), Performance Evaluation (9), and Improvement (10). This maps to the Plan-Do-Check-Act cycle.

What is the difference between ISO 9001:2015 and ISO 9001:2008?

The 2015 revision introduced risk-based thinking, removed the requirement for a quality manual, eliminated preventive action as a standalone requirement (incorporated into risk-based thinking), emphasized leadership engagement, and adopted the High Level Structure for compatibility with other ISO management system standards.
