WHAT IS ENGINEERING DATA MANAGEMENT?
’Engineering Data Management’ (EDM) refers to the process of systematically acquiring, storing, organising, and maintaining engineering data throughout its lifecycle.
This practice ensures data quality, accessibility, security, and usability across an organisation – it is a structured approach to managing all engineering-related data from creation through to end-of-life.
6 Key Aspects of Engineering Data Management
Fundamentally, we can break down such a vast topic into a handful of key mechanisms:
- Data Acquisition: Collecting engineering data from various sources such as design tools, simulation, and other data sources.
- Data Storage: Securely storing engineering data in a centralised repository, using a specialised software system such as Product Data Management (PDM).
- Data Organisation: Structuring and classifying engineering data for easy retrieval, analysis, and reuse, including metadata management.
- Data Validation: Ensuring the accuracy, integrity, and consistency of engineering data.
- Data Analysis: Utilising tools to analyse engineering data for insights into engineering and product performance.
- Data Governance: Establishing policies and procedures for managing data access, security, and compliance with relevant regulations.
These mechanisms underpin product development cycles, and managing these without the right tools requires a shed-load of patience and can drain resources, limit organisations, and heavily impact productivity.

Register Here The Unseen Benefits of Engineering Data Management
There are huge benefits to be realised by an organisation implementing Engineering Data Management, including:
- Improved Collaboration: Enables seamless sharing of engineering data across teams and departments.
- Enhanced Decision Making: Provides reliable and readily accessible data for informed engineering decisions.
- Increased efficiency: Streamlines engineering workflows by reducing data redundancy and eases access.
- Cost Reduction: Cuts duplicated effort and minimizes the need for data re-entry and rework by maintaining a single source of truth.
- Product Quality: Eases analysis of design variations and potential issues to enhance product quality.
These benefits often affect the processes and workflows that happen in the background of organisations and product development.
EDM provides the structure and maintenance framework that helps organisations to maximise efficiencies and generate higher quality output from the same inputs.
This theoretical definition gives a good insight into the subject matter and key aspects of EDM. But, from a practical point of view, how does EDM work and what does it look like to the end users?
How can organisations deploy a system to realise the benefits of improved EDM? Well, it all starts with effective management of your data…
’Product Data Management (PDM)’ is a system that centralises and organises all product-related information.
This includes all CAD data and other associated technical documentation generated across a product's lifecycle to ensure all teams within a company have access to correct and consistent data for better collaboration and decision-making.
10 Key Features of a PDM System
A PDM system is the main technology for enabling EDM in an engineering and product design environment.
By deploying PDM, an organisation can manage and store product data in a single, accessible location to streamline operations and improve efficiency. Let's dive into 10 of the key features of a PDM system like SOLIDWORKS PDM.
#1 - Centralised Data Storage
A common analogy used to describe a PDM system is a “Vault”.
It is true that a PDM system protects product information and maintains its integrity in a secure way, but rather than a vault, consider that a “Library” is a better analogy for describing a PDM system.
Like a library, a PDM system stores information in one place, cutting the need to search for data across different systems or departments.
Rather than locking product information away, the primary purpose of a PDM system is to share product information between teams, ensuring everyone can access accurate information and fostering better decision-making and collaboration between teams.
Public libraries are the original knowledge-sharing technology, and PDM provides organisations with their very own, private space for their documentation.
#2 - Data Organisation
To continue the library analogy, the information in a PDM system is well organised and structured, making it easy to retrieve and reuse.
SOLIDWORKS PDM sits within the familiar Windows Explorer interface for ease of use, and it combines logical folder structures with data cards to capture and display part number, description, revision, and other important information known as metadata.
PDM systems are normally the custodians of part and document numbers and prevent duplication of this data. SOLIDWORKS PDM has user-defined templates to automate file creation and support data structure and organisation.
#3 - Data Integrity
When it comes to CAD data, the robust management of file-to-file references and cutting duplication is critical to data integrity.
If tackled manually, this is an almost impossible task and inevitably leads to loss of valuable design data, reduced productivity (due to rework and duplicate design effort), and poor product quality (due to the lack of correct design data).
Through the support of embedded CAD integrations, PDM systems automatically capture CAD file references and bi-directionally map information between the PDM system and the CAD files (and other documentation) so that it always up to date.
Instead of shuffling and managing files, engineers can focus on their design tasks when they have the support of a strong data management system.

The primary benefit of a PDM system is the ability to easily find and reuse product information.
It is not only the time saved when searching for information, but the much larger productivity gains associated with the reuse of existing, proven designs.
#5 - Version & Revision Control
A PDM system provides version and revision control to ensure that all changes made to a document or CAD file are tracked and recorded.
This helps to reduce the risk of errors, inconsistencies, and duplication of effort, which can be costly and time-consuming. Returning to the Library analogy once more, users can “Check Out” files to make design changes without affecting the latest released version.
Meanwhile, team members are aware of changes being made and can continue with their own design work in parallel. When design changes are complete, files can be “Checked In” and made available to teammates to update their design.
File versions can be working versions or revision-stamped, formerly released versions, which are made available to a wider audience. Plus, there are no ‘shushing’ librarians here…
#6 - Lifecycle Status
The current stage or phase at which you find a CAD design or document is its lifecycle status. This lifecycle is tracked by a PDM system and shows a file’s position within the development process.
In SOLIDWORKS PDM, CAD file and document status is controlled via configurable workflows. Different workflows can be assigned to different file types and have different statuses.
#7 - User Access Control
A key component of a PDM system is the ability to control access to the engineering data it maintains; this could be to ensure there are no unauthorised changes by engineers, or make sure consumers of engineering information are viewing the latest released version of a drawing only.
User access and authorisation is normally applied to groups of users rather than individual users to make it easier to manage.
Authorisation is also applied to the lifecycle status of files and their location or classification within the PDM system.
In SOLIDWORKS PDM, user access and authorisation is applied to workflow states which control what can be done to a file, while workflow transition permissions control who can promote files from one workflow state to another.

Learn More #8 - Application Integration
To maximise design productivity and efficiency, a good PDM system includes direct integration with CAD tools and other applications that may be used to generate to new design and product information.
Through a PDM interface, ‘Search’ tools make it easy to rapidly find and load the latest design files, while a command-rich menu ensures that data management tasks are performed as part of the design process, instead of being an afterthought or a separate operation.
Design teams can collaborate more effectively, share design changes more easily, and maintain access to only the latest design files through PDM interfaces or integrated task panes within CAD tools like SOLIDWORKS.
#9 - Bill of Materials (BoM)
PDM systems automatically manage the BoM data encapsulated in a 3D CAD assembly and provide visibility to users who do not have access to the CAD authoring tools.
The BoM information is normally presented in tabular format which can be manipulated to display the BoM in different formats, such as a full idented BoM, a single level BoM or a flattened or parts only BoM.
Component metadata such as part number, description, material, revision, quantity, and other information can be included in the BoM enabling users to search for components and compare different versions of a BoM to identify changes.
Systems such as SOLIDWORKS PDM can export component and BoM information in different neutral file formats to facilitate the transfer of data to third-party business systems (such as an ERP system) and eliminate the time-consuming and error-prone process of manual data entry.
#10 - Change Notes
In a PDM system, change notes are one of the standard forms for an engineering change process.
Typically, this document records the changes made to CAD files and other technical documentation before transitioning between stakeholders for change approval and sign-off.
Change notes combine with revision controls and lifecycle workflows to provide a full history and audit trail of engineering changes that are vital for compliance purposes.
PDM VERSUS PLM - PRODUCT LIFECYCLE MANAGEMENT
Product Data Management, therefore, forms one part of the product lifecycle management (PLM) process.
PLM involves managing the processes required to take a product from its initial inception all the way through to manufacture, production, retirement, and disposal.
PDM forms part of Product Lifecycle Management. Many commonly consider PLM a system, but it could be considered more of a philosophy, or guiding principle, for product development and delivery.
As soon as an idea for a product is conceived, PLM has begun – at some point along that journey (perhaps when the first files are being generated), PDM will likely be required and find its place and its own lifespan within PLM and the product development cycle.
That said, tools and PLM systems do exist which are more advanced, record-based data management systems.
These extend the file management and application integrations enabled by a PDM system to include a comprehensive set of capabilities that you can use and distribute to many areas of your business to improve and fully realise the benefits of Engineering Data Management.
Manage Engineering Data with Confidence
A product data management system such as SOLIDWORKS PDM is crucial for engineering and design teams as they centralise and organise product-related information.
That way, you can be certain that everyone in your organisation has access to the latest, correct data, leading to improved collaboration, faster product development cycles, reduced errors, and better overall decision-making by everyone involved.
