An organization has decided to implement a QMS based on ISO 9001.

Comprehensive and Detailed In-Depth Explanation:

ISO 9001:2015 requires organizations to assess both internal and external issues that could impact the effectiveness of their Quality Management System (QMS).

Clause Reference:

Clause 4.1 – Understanding the Organization and Its Context states that organizations must determine external and internal issues that affect their ability to achieve intended results.

Internal issues include:

Knowledge within the organization (documented or undocumented)

Organizational culture

Resource availability

Technological advancements

Infrastructure and capabilities

Why is the Correct Answer C?

Knowledge (Clause 7.1.6) is a critical internal factor that directly affects the implementation and maintenance of a QMS.

Organizations must identify, maintain, and make available the necessary knowledge to achieve quality objectives and meet customer requirements.

Why are the Other Options Incorrect?

A (Social and economic environments) → These are considered external issues rather than internal.

B (Competitive environment) → Competition is external, not an internal issue affecting the QMS.

D (Expectations of suppliers) → Supplier expectations relate to external interested parties, covered under Clause 4.2 (Understanding the Needs and Expectations of Interested Parties).
