You must have heard about the term Quality Management System or QMS! The Quality Management System is also known as QMS is a baseline requirement to implement processes and requirements as per ISO 9001 or IATF 16949 or ISO 17025.
What is Quality Management System (QMS)?
A QMS covers all key essential elements, activities, processes, sub-process, work-instruction, forms, records of the product manufacturing process or service processes to meet customer requirements, statutory and regulatory requirements.

Quality System Pyramid
Hierarchy in the QMS system is being followed in various industries. Each QMS level or hierarchy level defines the intent of QMS. In the majority of industrial sectors, four levels of quality system pyramid are used.
Let’s review QMS levels one by one.
Level 1 – Quality Manual:
A Quality manual acts as a manual to define, deploy and operate the overall quality management system in the organization. A Quality manual covers each sub-process requirement and interaction of processes within the organization. A Quality manual can be drafted based on industry standards like ISO 9001 or ISO 13485 (for a medical device) or IATF 16949 (for the automotive industry).
Quality Policy and Objective: Quality Policy is the overall organization’s strategic decision and expectation about product or service quality. Quality Policy and objective are part of the Quality manual.
Level 2 Standard operating procedures:
Standard Operating procedures are also known as SOP or procedures. SOP / Quality procedure covers,
- In scope / Out of Scope
- Roles and Responsibilities
- What is to be achieved.
- Interaction with other procedures / SOP.
- Fulfilling requirements as per level 1
In simple words, SOP/procedure defines WHO, WHEN, WHERE!
Level 3 Work Instruction:
A work instruction covers the ‘How part’. A work instruction is a detailed step-by-step method that is used to achieve the desired outcome.
Level 4 Forms & Records:
The last level of the Quality Pyramid is forms and records. This level indicates i.e. requirements laid out in Quality Manual, Quality procedures, and work instructions are followed. Quality records serve as compliance to Quality Management System.
Level 4 records serve as objective evidence are subject to review during the internal and external audit. Level 4 Records prove whether an organization is following level 1 to 3 requirements or not.
Following image represents different levels of the Quality management system documentation. Level 1 to 4 is most commonly used in the majority of business sectors.

Following a high-level table helps to understand types of documents, procedures, and records at each quality pyramid level.
