What is a Design History File (DHF) in FDA and ISO-regulated product development?

A Design History File (DHF) is a structured collection of records that shows a product was developed according to approved procedures. It typically includes design inputs and outputs, risk management records, verification and validation results, design reviews, and change documentation.

Why is maintaining a DHF difficult with spreadsheets and email?

Spreadsheets and email scatter records across folders, inboxes, and personal drives. This creates version conflicts, missing approvals, and extra effort during audits because teams must manually rebuild the history of decisions and changes.

Why is change management critical in FDA and ISO-regulated environments?

Change management ensures design, document, and component updates are reviewed for technical, quality, and regulatory impact before release. It also provides traceability by recording what changed, why it changed, who approved it, and when it was implemented.

How does a controlled workflow improve change reviews and approvals?

A controlled workflow standardizes review steps, routes approvals to the right stakeholders, and captures electronic signoff. This reduces delays, prevents unauthorized changes, and creates an audit-ready record of the decision process.

Why is the bill of materials (BOM) a compliance item for regulated products?

For regulated products, the BOM defines the approved product configuration used to build and verify the product. Each change must be assessed for safety, performance, and compliance impact, and the BOM must remain controlled with revision history and approvals.

How does a BOM support regulatory traceability?

A BOM connects parts and assemblies to specifications, risk assessments, and verification and validation evidence. This linkage helps show how requirements move into design and then into manufacturing, supporting investigations and audit requests.

What is the difference between an EBOM and an MBOM in regulated manufacturing?

An EBOM represents engineering intent and the product design definition, while an MBOM represents the approved build structure used in production. Keeping them aligned helps prevent building from outdated instructions and reduces compliance and quality risk.

How do EBOM changes relate to the DHF?

EBOM changes are part of the product’s design evolution and must be supported by reviews, approvals, and evidence such as test results. Linking EBOM revisions to change records and supporting documents helps maintain a clear design history for audits.

How does BOM management software support FDA and ISO expectations?

BOM management software supports controlled processes through version control, traceability, workflow automation, and audit trails. It reduces reliance on manual tracking and helps teams demonstrate data integrity and documented approval paths.

How does a unified system improve cross-functional collaboration for regulated teams?

A unified system gives engineering, quality, regulatory, operations, and supply chain teams access to the same current records. This reduces miscommunication, speeds decisions, and helps ensure changes are implemented consistently across groups.

How to Streamline Change Management and Design History Files in FDA and ISO-Regulated Environments

Manufacturers of high-tech and medical devices operating in areas governed by the FDA and ISO must constantly strike a balance. They must be quick to innovate while upholding strict process control, traceability, and documentation. All design decisions, requirements, tests, and approvals need to be documented and kept on file. Product safety and regulatory compliance are based on these records.

For regulated teams, the design history file (DHF) and change management are two areas that frequently cause conflict. Teams suffer from delays, discrepancies, and audit stress when these procedures depend on spreadsheets, email, and disjointed platforms. Arena by PTC offers a cloud-native platform that integrates product data, documentation, and change management to enable businesses to operate effectively while adhering to regulations.

The DHF as a Living Compliance Record

A systematic collection of documents known as the DHF shows that a product was created in accordance with established and authorized procedures. Design plans, specifications, risk assessments, validation and verification outcomes, and change logs are usually included.

It takes a lot of effort to manually maintain the DHF because records frequently end up dispersed between systems, folders, and personal drives which makes audits challenging and prone to mistakes. Arena creates a dynamic DHF that remains up to date and comprehensive by automatically capturing records as part of everyday activities.

Why Change Management Matters in Regulated Environments

Before implementation, change management ensures that changes to designs, procedures, or components are assessed for their technical, quality, and regulatory implications. Every change in a regulated environment needs to be reviewed, authorized, and recorded for traceability.

For change requests and change orders, Arena offers automated workflows that impose review and approval procedures. Every modification is associated with the items, documents, and tests that are impacted. This lowers risk and increases responsibility by clearly documenting what changed, why it changed, and who approved it.

BOM Management Best Practice

To properly manage the BOM, most organizations select a BOM management software solution to help ensure the most current product revisions are seen by all members of the production team. Learn why a BOM management tool is important, your options, and what to look for in a solution.

The Bill of Materials as a Compliance Item

The bill of materials (BOM) is more than just a production list in businesses that are subject to regulations; it’s a compliance item that outlines the precise contents and construction of the product. The effects of any modifications to the BOM on performance, safety, and regulatory compliance must be assessed. To maintain accurate and defendable product definitions, Arena centralizes the BOM in a controlled environment with revision control, approvals, and audit trails.

What Is a BOM, and How Does It Support Traceability?

From the perspective of regulatory traceability, a BOM is the organized connection between compliance documentation, design intent, and manufacturing execution. Arena links the BOM to approvals, test results, risk assessments, and specifications. As a result, a digital product thread is created that facilitates traceability throughout the product lifecycle. Auditors can observe the process by which specifications are converted into designs and then into manufactured goods.

What Is a Manufacturing BOM (MBOM) for Regulated Products?

What is an MBOM? When compliance is necessary in manufacturing, a manufacturing BOM, or MBOM is the authorized set of instructions for creating items that comply with the regulations. Arena ensures that manufacturing teams consistently use the latest approved MBOM. Errors are avoided and reliable production is supported by controlling and prohibiting the use of outdated or unapproved versions.

Engineering BOM (EBOM) and Design Control

The product as intended by engineers is maintained on the EBOM. It displays the system architecture, performance objectives, and design intent. Arena helps manage the EBOM with robust revision control, approval workflows, and direct links to tests and requirements to ensure effective design control and compliance throughout development. Proper signoff is required before any change are released to ensure design integrity and maintain control.
