Types of Quality Control in a Company: What, How and Why to Check

# Articles
Submit an application

1. Incoming inspection

Purpose: to make sure that delivered materials, raw materials or components meet the requirements of the contract, the specification and the regulatory documents.

What is checked:

  • accompanying documents: certificates, quality passports (manufacturer's quality certificates), consignment notes;

  • compliance with technical requirements: GOST standards (Russian national standards) and technical specifications (TU);

  • condition of packaging and marking, any damage;

  • moisture content, composition, dimensions and other critical parameters.

2. In-process (or ongoing) inspection

Purpose: to ensure that the product or service meets the specified parameters during production.

How it works:

  • it is carried out directly at workstations;

  • it is performed by foremen, engineers from the quality control (QC) department and process engineers;

  • any deviations from standards are recorded and corrected immediately;

  • infrared cameras, visual inspections, sensors and automated inspection systems may be used.

Benefits:

  • prevents defective products from being made in large quantities;

  • reduces losses;

  • saves the resources that would otherwise go into correcting errors at the final stages.

3. Acceptance inspection

Purpose: to check finished products before they are passed to logistics, the warehouse or the customer.

What is checked:

  • completeness, integrity and appearance;

  • compliance with the documentation and customer requirements;

  • test results;

  • packaging, marking and any rejectable defects.

Key point: acceptance inspection often ends with a formal report. If the goods are for export, the results are entered in the accompanying documents (for example, veterinary, phytosanitary or customs documents).

4. Random spot checks

Purpose: to check, without prior notice, that standards and discipline are being observed.

How they are carried out:

  • at random, with no pre-approved schedule;

  • both by the internal control function and by external auditors;

  • in production, in warehouses, on the sales floor and even at remote storage sites.

5. Final inspection

Purpose: the final check of a product or service before handover to the client, shipment or project launch.

Unlike acceptance inspection, it is a more in-depth check that often includes laboratory or endurance (service life) tests.

What it includes:

  • a full analysis of quality and safety;

  • testing under operating conditions;

  • preparation of test reports;

  • specialist opinions and, where necessary, certificates.

6. Internal audit (self-assessment)

Purpose: to identify process problems systematically, without waiting for complaints.

How it is carried out:

  • in accordance with the company's internal procedures;
  • at intervals set out in the quality policy;
  • by the quality function, internal auditors or a third-party company.

Benefits:

  • helps build a culture of continuous improvement (in line with ISO 9001);

  • reduces dependence on external supervision;

  • helps prepare for inspections, certification and the implementation of standards.

7. Inspections by government authorities and customers

Who inspects:

  • the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor), the Federal Service for Veterinary and Phytosanitary Surveillance (Rosselkhoznadzor), the Federal Service for Environmental, Technological and Nuclear Supervision (Rostekhnadzor), the Federal Tax Service (FNS) and others;

  • certification bodies;

  • customer representatives, especially in tenders and public procurement projects.

What matters:

  • compliance with the law;

  • having all the required records (test reports, logbooks, inspection reports);

  • compliance with sanitary, technical, labour and environmental standards.

What documents are drawn up after inspection?

  • Incoming, acceptance or production inspection reports;

  • Laboratory test reports;

  • Inspection result logs;

  • Declarations of conformity to Customs Union Technical Regulations (TR TS) or GOST R standards;

  • Audit and corrective action reports;

  • Certificates or reports from independent laboratories.

Typical mistakes in organising control

  • procedures are missing or a mere formality (box-ticking control);

  • untrained staff;

  • no proper document management and no recording of deviations;

  • poor communication between departments (for example, the quality control department does not work with production);

  • no automation (everything is on paper, so data gets lost).

How to build an effective control system in a company

  1. Appoint someone responsible: the head of quality must have authority and management support;

  2. Develop internal regulatory documents: instructions, checklists, report templates;

  3. Define the types and frequency of inspections;

  4. Train staff, especially on the shop floor;

  5. Introduce recording and analysis systems (for example, a QMS, ERP or 1C);

  6. Carry out internal audits regularly and adjust processes;

  7. Bring in external experts and auditors when you need independent data.

Why control should be split by type: a mistake many companies make

Many companies try to cover all control with a single function, usually acceptance inspection. As a result:

  • there is no incoming inspection, and poor-quality raw materials go into production;

  • no random spot checks are carried out, so employees become complacent and break standards;

  • no audits are conducted, so management does not get an objective picture.

The consequences are not only internal losses but also fines from regulators, product recalls and lost contracts.

Control costs money. Lack of control can cost you the business.

Modern control tools

To make their control systems fast, reliable and transparent, companies introduce a range of technologies.

Digital inspection tools:

  • checklists and photo records in apps (for example, 1C:OTK, Controlio, Prengi);

  • automatic alerts when deviations occur;

  • geotagged and time-stamped inspections (for field visits and random spot checks).

Analytics and BI reports:

  • visualisation of inspection results;

  • identification of recurring violations;

  • management reports without manual preparation.

The role of the quality control (QC) department

Even when control is spread across departments, the QC department remains the centre of responsibility. Its functions are:

  • developing standards and procedures;

  • training employees;

  • auditing compliance with requirements;

  • analysing complaints and the causes of defects;

  • working with certification and supervisory authorities;

  • maintaining regulatory documentation.

Without a structured QC department, control will sooner or later descend into chaos.

Bringing in external inspection: when it is needed

External inspection is needed if:
  • the product is exported;
  • you need legal protection in disputes;
  • the company lacks the necessary competencies or resources in-house;
  • you need to prepare for ISO, HACCP or GMP certification;
  • you are starting to work with a new partner or marketplace (Ozon, Wildberries, X5, etc.).

TopFrame provides independent inspection services for logistics, agriculture, industry and retail. We are your external QC department anywhere in Russia and the Eurasian Economic Union (EAEU) countries.

If you want control to be a tool for development rather than a burden, it has to be built on logic, transparency and the real needs of the business. This is where outsourcing providers such as TopFrame can help. We carry out:

  • acceptance inspections, laboratory testing, on-site inspections and random spot checks;

  • production process audits;

  • certification testing and preparation of documentation;

  • independent expert examination of the quality of goods and packaging.

If you need a safe pair of hands and a fresh outside perspective, TopFrame will step in as an external expert, set up your control system and help you avoid typical mistakes.
