Structure of PJSC Gazprom’s QMS

As part of the QMS, procedures for managing substandard products were developed. When substandard quality products are detected, the Gazprom Group companies will promptly inform customers. In such instances, products with unidentifiable or questionable status are classified as noncompliant.

Substandard product management process includes:

  • identification of such products;
  • corrective action as required;
  • product reverification;
  • analysis of causes of noncompliance to enable corrective action.

Compliance with International Standards

60 companies of the Gazprom Group were certified for compliance with the ISO 9001:2015 international standard, with two of them — Gazprom Mezhregiongaz and Gazprom Energoholding — certified in the reporting year.


Control of the Supplier Performance Quality

To ensure a high quality of products, works, and services, PJSC Gazprom recommends that its suppliers implement QMS systems based on the STO Gazprom 9000 corporate standards.

These standards provide for stricter requirements compared to similar international and national standards, and introduce additional requirements to ensure the quality of products, works and, services taking into account the nature of the safe operation of PJSC Gazprom’s facilities.

As of December 31, 2021, 166 suppliers of materials and equipment, works, services, and 14 subsidiaries of the Gazprom Group certified their QMS for compliance with STO Gazprom 9001.

Customer Satisfaction Monitoring

To ensure a sustained high quality of products, Gazprom monitors customer satisfaction on a regular basis. In 2021, customer satisfaction was monitored using the two independent methods:

  • Method 1. Analysis of data obtained by collecting feedback from the customers of PJSC Gazprom’s subsidiaries across all lines of business.
  • Method 2. Calculation of the customer satisfaction index for the following lines of business: gas business, power generation business, NGV fuel business.

Based on 2020 results, the average customer satisfaction index in line with Method 1 remained at a high level of 4.80 (using a 5-point scale).

The results of customer satisfaction monitoring in 2021 will be summed up after subsidiaries and entities of PJSC Gazprom report on performance of their quality management systems in 2022 (it will be the first time that a 10-point scale will be used for customer satisfaction assessment).
