Factory Process Control is one of the most important, and often misunderstood, concepts within manufacturing compliance.
For businesses involved in fabrication, construction products, engineering or manufacturing, Factory Process Control forms the backbone of consistent production, quality assurance and regulatory compliance. When implemented properly, it becomes a practical operational framework that helps organisations reduce defects, improve traceability, strengthen customer confidence and demonstrate conformity with recognised standards.
The term “Factory Process Control”, often shortened to FPC, refers to the documented systems, procedures and controls that manufacturers use to ensure products are consistently produced to the required specification. In simple terms, it is the mechanism that demonstrates a factory is operating in a controlled and repeatable manner.
This becomes particularly important where products are safety critical or subject to legal and contractual obligations. In sectors such as structural steelwork, aluminium fabrication and construction manufacturing, failures in production control can have serious commercial and safety consequences. Because of this, many standards and regulatory schemes require manufacturers to operate formal Factory Process Control systems.
One of the most widely recognised examples is BS EN 1090, which governs the execution of steel and aluminium structures across construction supply chains.
Why Factory Process Control Matters
Many organisations assume Factory Process Control is purely about certification, but actually it has a far wider operational impact.
Manufacturing businesses operate in increasingly demanding environments where customers, regulators and contractors expect evidence of consistency, traceability and competence. A company may produce an excellent product most of the time, but without controlled processes and records, it becomes difficult to prove conformity consistently.
Factory Process Control provides that assurance.
An effective FPC system helps organisations demonstrate that raw materials are sourced appropriately, production activities are controlled, inspections are completed correctly and finished products conform to specification before release. It also creates accountability throughout the manufacturing process by defining responsibilities, competencies and inspection requirements.
For many organisations, Factory Process Control also becomes commercially important. Increasingly, principal contractors and procurement teams expect suppliers to hold recognised certifications and robust production controls before awarding work. In competitive sectors, a weak or poorly implemented Factory Process Control system can quickly become a commercial disadvantage.
Factory Process Control and BS EN 1090
Factory Process Control is heavily associated with BS EN 1090 because the standard specifically requires manufacturers to establish and maintain a documented production control system.
BS EN 1090 applies to organisations involved in the manufacture of structural steel and aluminium components used within construction projects. This includes structural steel fabricators, architectural metalwork companies and manufacturers producing load-bearing structural elements.
Under BS EN 1090, Factory Process Control is not optional. Manufacturers are required to demonstrate that products are manufactured under controlled conditions and that the organisation can consistently achieve conformity with the relevant execution class requirements.
In practice, this means businesses must maintain controls covering areas such as material traceability, welding quality, inspection activities, competency management and calibration of equipment.
Material traceability is a particularly important aspect. Manufacturers must be able to demonstrate where materials originated from and how they have moved through the production process. This often involves maintaining mill certificates, batch controls and identification systems that allow materials to be tracked throughout fabrication.
Welding activities are also heavily scrutinised under BS EN 1090 because welding quality directly impacts structural integrity. As a result, Factory Process Control systems frequently incorporate controls linked to ISO 3834-1 (Quality requirements for fusion welding of metallic materials), including welding procedure specifications, welder qualifications and inspection arrangements.
Inspection and testing activities form another core element of Factory Process Control. Organisations must define what inspections are carried out, when they occur, who performs them and how results are recorded. This may include dimensional inspections, weld inspections, coating checks and final release inspections before products leave the factory.
Is Factory Process Control the Same as ISO 9001?
This is one of the most common questions organisations ask when researching Factory Process Control.
The short answer is no. But there is significant overlap.
ISO 9001 is a broad quality management standard designed to help organisations manage quality consistently across their operations. It applies to almost any industry or business type.
Factory Process Control, however, is usually far more focused on manufacturing activities and product conformity.
An organisation may hold ISO 9001 certification and still need a separate Factory Process Control system to satisfy product-specific requirements such as BS EN 1090. However, businesses that already operate mature ISO 9001 systems are often in a much stronger position because many of the required controls already exist in some form.
For example, ISO 9001 already promotes areas such as document control, competency management, internal auditing, corrective action and supplier management. These same principles appear within Factory Process Control systems, although usually with greater technical detail and production-specific focus.
What Does a Factory Process Control System Include?
Although the exact requirements vary depending on the applicable standard and industry, most Factory Process Control systems contain several common elements.
Documented procedures are fundamental because organisations must define how manufacturing activities are controlled. This includes production processes, inspections, testing activities and release arrangements.
Supplier management is another critical area. Manufacturers cannot consistently produce compliant products if incoming materials and outsourced services are poorly controlled. As a result, Factory Process Control systems often include supplier approval processes, incoming inspection activities and verification checks for purchased materials.
Competency management also plays a major role. Personnel carrying out critical manufacturing or inspection activities must be appropriately trained and competent. In sectors involving welding or technical fabrication, this may include formal qualifications and approvals for welders, inspectors and quality personnel.
Equipment calibration and maintenance arrangements are equally important. Measuring equipment, torque devices, welding equipment and testing instruments must remain suitable and reliable if inspection results are to be trusted.
Internal auditing and management review processes are normally required as well. These activities help organisations identify weaknesses within their Factory Process Control arrangements and demonstrate ongoing oversight by leadership teams.
Common Problems with Factory Process Control
Many Factory Process Control systems fail because organisations approach them purely as certification exercises.
This often results in large volumes of paperwork that bear little resemblance to what actually happens within the factory environment. Auditors frequently encounter procedures that operators do not follow, incomplete traceability records, inconsistent inspections and weak control over nonconforming products.
Another common issue is overcomplication. Some organisations create excessively bureaucratic systems that become difficult to maintain. In reality, the best Factory Process Control systems are usually practical, operational and integrated into day-to-day manufacturing activities.
Poor communication between quality teams and production teams can also create major weaknesses. Factory Process Control only works effectively when production personnel understand why controls exist and how they contribute to product conformity and customer confidence.
Who Needs Factory Process Control?
Factory Process Control is commonly associated with steel fabrication and construction manufacturing, but its principles extend far beyond those sectors.
Businesses involved in engineering, aerospace, automotive manufacturing, rail, medical devices and specialist fabrication often operate similar production control systems because customers and regulators increasingly expect demonstrable evidence of controlled manufacturing.
Even where Factory Process Control certification is not legally required, many organisations voluntarily strengthen production controls to reduce defects, improve efficiency and enhance credibility within supply chains.
As supply chain scrutiny increases, organisations without robust production controls may find themselves excluded from tender opportunities or higher-risk projects.
