PLM Software

How to Choose the Best PLM Software

Product lifecycle management software helps product companies control the information, decisions, approvals, and changes involved in taking a physical product from early concept through engineering, production, service, and eventually retirement.

Choosing PLM software is different from choosing a simple project-management or collaboration tool.

The decision can affect engineering data, bills of materials, CAD workflows, manufacturing handoffs, suppliers, quality processes, product changes, and other systems such as ERP and CRM.

A hardware startup managing its first complex BOM has very different requirements from a global automotive manufacturer coordinating thousands of parts, engineering teams, suppliers, plants, and regulatory requirements.

Before comparing platforms, identify where product information currently breaks down.

Common problems include engineers working from outdated files, uncontrolled spreadsheet BOMs, slow engineering change approvals, disconnected CAD and ERP data, poor supplier visibility, duplicate part records, and teams struggling to identify the latest approved product configuration.

The right PLM platform should solve those problems without introducing more process complexity than the organization can realistically manage.

PLM Software on HowToBuySaaS by Use Case

These products serve noticeably different requirements.

A company should not select PLM software simply because one product has more features than another. The better question is whether the platform fits the company’s product complexity, engineering systems, industry, implementation resources, and existing technology stack.

What Is PLM Software?

PLM stands for Product Lifecycle Management.

PLM software provides a structured system for managing product information and product-development processes throughout the lifecycle of a product.

That lifecycle may include:

Idea → Design → Engineering → Validation → Sourcing → Manufacturing → Launch → Service → Retirement

PLM platforms can connect information from several departments that participate in this process.

Depending on the software and industry, PLM may manage:

1. parts and items
2. bills of materials
3. CAD-related product data
4. specifications
5. engineering documents
6. product requirements
7. revisions
8. engineering changes
9. approvals
10. suppliers
11. quality processes
12. product configurations
13. compliance information
14. new-product introduction
15. manufacturing handoffs
16. project information
17. product records

The goal is to create a controlled source of product information so different teams are not making decisions from conflicting spreadsheets, files, emails, or outdated revisions.

Who Uses PLM Software?

PLM originated in industries where product complexity creates a significant information-management problem, but its use now extends across many product-driven businesses.

Manufacturing Companies

Manufacturers may use PLM to connect engineering information with sourcing, production, quality, and other downstream processes.

The system can help manage:

1. product structures
2. parts
3. BOMs
4. revisions
5. engineering changes
6. drawings
7. supplier information
8. product releases

Manufacturing organizations should pay particular attention to how PLM connects with CAD, PDM, ERP, and manufacturing systems.

Hardware Companies

Hardware startups and technology companies often reach a point where spreadsheets and shared folders are no longer sufficient.

As the number of parts, suppliers, revisions, and product variants grows, teams need stronger control over product information.

Useful capabilities include:

1. component management
2. BOM management
3. revision control
4. engineering changes
5. supplier collaboration
6. approved parts
7. product releases
8. CAD integrations

Duro and OpenBOM are particularly relevant examples of software built around hardware and manufacturing data workflows.

Automotive and Aerospace

Automotive and aerospace products can contain extremely complex product structures with strict engineering, quality, configuration, and traceability requirements.

Organizations in these industries may need:

1. multi-level BOM management
2. configuration management
3. engineering change control
4. requirements management
5. supplier collaboration
6. compliance records
7. digital thread capabilities
8. product variants
9. detailed permissions
10. large-scale CAD integration

Enterprise implementation and integration capabilities become particularly important at this level.

Electronics and High-Tech Manufacturing

Electronics companies may need to coordinate mechanical, electrical, and supply-chain information while managing rapidly changing components.

Relevant PLM requirements can include:

1. electronic components
2. BOMs
3. approved manufacturers
4. supplier data
5. lifecycle status
6. revisions
7. change orders
8. compliance information
9. CAD and ECAD integrations

Component availability and supply-chain changes can make accurate product records especially important.

Retail, Apparel, and Consumer Products

Retail-oriented PLM can look considerably different from engineering-heavy industrial PLM.

Brands may need to manage:

1. product concepts
2. collections
3. product specifications
4. supplier communication
5. costing
6. samples
7. approvals
8. sourcing
9. purchase information
10. product launch timelines

Surefront is one example in the current HowToBuySaaS marketplace aimed specifically at brands, retailers, and suppliers.

Medical Devices and Regulated Products

Regulated manufacturers may require particularly strong control over:

1. product records
2. approvals
3. changes
4. traceability
5. documents
6. quality processes
7. audit history
8. requirements

When evaluating PLM for a regulated industry, confirm the exact compliance, validation, audit, and quality-management capabilities required by your organization rather than assuming every PLM system provides them.

Core PLM Software Features

Bill of Materials Management

The bill of materials, or BOM, describes the components and assemblies that make up a product.

A simple product may have a relatively short BOM.

A complex product can contain many levels of assemblies and thousands of individual parts.

PLM software can help teams manage:

1. multi-level BOMs
2. quantities
3. revisions
4. part relationships
5. product structures
6. variants
7. approved components
8. supporting documents

BOM management becomes particularly important when several teams depend on the same product definition.

Engineering Change Management

Products change throughout development and production.

An engineering change process provides a controlled way to request, evaluate, approve, implement, and document those changes.

Common concepts include:

ECR: Engineering Change Request

ECO: Engineering Change Order

A PLM system can help record:

1. what is changing
2. why it is changing
3. affected parts
4. affected BOMs
5. reviewers
6. approvals
7. implementation status
8. revision history

Without a controlled change process, one team may update a product while another continues working from an older version.

Revision and Version Control

Product data should make it clear which version is current and approved.

Revision control helps prevent situations where manufacturing, procurement, suppliers, and engineering use different versions of the same information.

This may apply to:

1. parts
2. BOMs
3. CAD files
4. drawings
5. specifications
6. documents

Product Data Management

PLM often becomes a central layer for product information.

This may include:

1. part numbers
2. descriptions
3. attributes
4. product structures
5. documents
6. specifications
7. lifecycle status
8. revisions

Some organizations use separate PDM software for detailed engineering-file control while PLM manages the broader product lifecycle and business processes.

Workflow and Approvals

PLM software can formalize processes that might otherwise happen through email.

Examples include:

1. product release
2. engineering changes
3. design reviews
4. supplier approvals
5. quality processes
6. new-product introduction
7. document approval

Good workflow software should create control without forcing every minor decision through an unnecessarily complicated process.

Supplier Collaboration

Product development frequently involves external manufacturers and suppliers.

Relevant PLM functionality may include:

1. controlled supplier access
2. RFQs
3. product specifications
4. BOM sharing
5. supplier data
6. approvals
7. sourcing information
8. change communication

Check carefully how external users are licensed and what information suppliers can access.

Requirements Management

Complex products often begin with formal requirements.

PLM can connect requirements with product development and change processes so teams can understand why a feature, component, or engineering decision exists.

Quality Management

Some PLM platforms extend into quality workflows.

These may include:

1. nonconformance
2. corrective actions
3. preventive actions
4. supplier quality
5. failure analysis
6. quality documentation

The depth of quality-management functionality varies significantly between platforms.

PLM vs PDM: What Is the Difference?

PLM and PDM overlap, but they are not identical.

PDM, or Product Data Management, is generally focused on engineering data such as CAD files, revisions, drawings, and related design information.

PLM operates across a wider portion of the product lifecycle.

It may connect engineering data with:

1. BOMs
2. change management
3. requirements
4. suppliers
5. quality
6. manufacturing
7. product programs
8. approvals
9. product portfolio information

A simple way to think about the distinction is:

PDM helps control engineering files and product data.

PLM helps control the wider product definition and the processes surrounding it.

Some products provide both capabilities, while other companies integrate separate PDM and PLM systems.

The distinction matters when comparing products. A company whose main problem is CAD file control may not need a full enterprise PLM implementation.

PLM vs ERP

PLM and ERP manage different parts of the product and business environment.

PLM is generally centered on what the product is and how its definition changes.

ERP is generally centered on how the business plans, buys, manufactures, sells, and accounts for products.

A simplified flow may look like:

Engineering creates and releases the product definition in PLM

↓

Approved product and BOM information moves into ERP

↓

ERP supports procurement, planning, inventory, production, costing, and financial processes

PLM and ERP therefore often need to exchange information.

Before purchasing PLM software, determine which system will own each important type of data.

PLM vs Project Management Software

Project management software tracks work.

PLM manages the product definition and the processes surrounding the product.

A project-management tool can tell you:

The engineering review is due Friday.

A PLM system may tell you:

1. which product revision is under review
2. which components are affected
3. which BOM is being changed
4. who approved the change
5. which documents belong to that revision
6. whether the updated product has been released

Many product companies use both systems.

Cloud PLM vs On-Premises PLM

Deployment model can have a major impact on implementation.

Cloud PLM

Cloud PLM is hosted by the software provider and accessed online.

Potential advantages include:

1. faster infrastructure setup
2. easier remote access
3. vendor-managed updates
4. reduced server administration
5. easier collaboration across locations

Cloud-native options can be particularly attractive to companies without large internal PLM infrastructure teams.

On-Premises or Self-Managed PLM

Some larger or highly specialized organizations may require more control over deployment, integrations, infrastructure, or data environments.

These implementations may demand substantially more internal administration and implementation expertise.

Do not choose between cloud and on-premises based only on preference.

Consider security requirements, integrations, implementation resources, customization, data governance, regulatory requirements, and long-term administration.

PLM Software by Company Size

PLM for Startups

A hardware startup should avoid recreating enterprise complexity before it needs it.

The initial problem is often straightforward:

1. BOMs are stored in spreadsheets
2. CAD data is difficult to control
3. suppliers receive outdated files
4. engineering changes are informal
5. product information is scattered

A startup may benefit most from lightweight cloud PLM or BOM-management software that can be deployed without a major consulting project.

Duro and OpenBOM are relevant products to investigate for this type of workflow.

PLM for Small and Mid-Sized Manufacturers

Growing manufacturers may require:

1. stronger BOM management
2. engineering change control
3. supplier collaboration
4. CAD integration
5. ERP integration
6. quality processes
7. controlled product releases

Implementation simplicity still matters, but the product needs enough structure to support growth.

Enterprise PLM

Enterprise PLM projects can involve thousands of users, global engineering teams, multiple CAD systems, suppliers, manufacturing sites, business units, and product families.

Evaluation criteria may include:

1. scalability
2. configuration management
3. multi-CAD support
4. product variants
5. integrations
6. requirements
7. manufacturing processes
8. quality
9. supplier collaboration
10. security
11. APIs
12. governance
13. global deployment

At this level, vendor selection is only part of the project. Data migration, process design, implementation partners, integrations, training, and adoption can determine whether the PLM program succeeds.

PLM Software by Industry

PLM for Manufacturing

Manufacturers should prioritize the connection between engineering data and downstream operations.

Evaluate:

1. BOM management
2. change management
3. product release
4. CAD integration
5. ERP integration
6. supplier collaboration
7. manufacturing handoff
8. quality

PLM for Hardware Startups

Hardware companies should look closely at:

1. speed of implementation
2. BOM usability
3. CAD integrations
4. revision management
5. component data
6. supplier collaboration
7. API access

The software should introduce control without slowing engineering teams unnecessarily.

PLM for Retail and Brands

Retail-oriented buyers may prioritize:

1. product development
2. supplier collaboration
3. sourcing
4. costing
5. quotes
6. product specifications
7. approvals
8. launch coordination

An industrial engineering PLM platform may be much more complicated than necessary for this use case.

PLM for Regulated Industries

Regulated organizations should verify:

1. traceability
2. approval history
3. access control
4. validation requirements
5. quality workflows
6. audit trails
7. documentation
8. electronic approvals

Requirements differ significantly by industry and jurisdiction, so do not assume the presence of a “compliance” feature automatically satisfies your specific regulatory obligations.

CAD Integration in PLM Software

CAD integration is one of the most important selection criteria for engineering-driven organizations.

Before selecting PLM software, document the CAD systems currently used across your organization.

Questions should include:

1. Which mechanical CAD systems are used?
2. Is ECAD data also involved?
3. Do different offices use different CAD products?
4. Are assemblies and dependencies preserved?
5. Can metadata be synchronized?
6. How are CAD revisions managed?
7. Can users work from their normal CAD environment?
8. What happens when an engineer checks in or releases a design?

Strong PLM functionality can still produce a poor engineering experience if the CAD integration does not fit the actual design environment.

PLM and ERP Integration

ERP integration is another major implementation consideration.

PLM may contain the engineering definition of a product while ERP manages operational and commercial data.

An integration may need to transfer:

1. released parts
2. BOMs
3. revisions
4. approved suppliers
5. lifecycle status
6. manufacturing information

Before implementation, define which system is authoritative for each field.

Allowing both systems to independently control the same information can create synchronization problems.

How Much Does PLM Software Cost?

PLM pricing is rarely as simple as paying one monthly subscription.

Vendors may charge based on:

1. named users
2. concurrent users
3. user roles
4. contributor users
5. modules
6. storage
7. integrations
8. API access
9. deployment model
10. implementation services

Enterprise vendors frequently use custom pricing.

PLM Implementation Costs

The software license may represent only part of the total investment.

Implementation can involve:

1. process discovery
2. configuration
3. customization
4. data migration
5. integrations
6. workflow design
7. testing
8. training
9. implementation partners
10. ongoing administration

When comparing PLM platforms, estimate total cost of ownership, not only license cost.

Why User Roles Matter

Not every person interacting with PLM needs the same level of access.

A company may have:

1. engineering authors
2. approvers
3. manufacturing users
4. procurement users
5. suppliers
6. management viewers

Some PLM vendors price these roles differently.

Understanding the number of users in each group can materially change the cost estimate.

How Long Does PLM Implementation Take?

There is no useful universal implementation timeline.

A cloud PLM implementation for a small product company with one workflow can be very different from replacing an enterprise PLM system across several global manufacturing sites.

Implementation time can be affected by:

1. number of users
2. data quality
3. legacy systems
4. integrations
5. customization
6. product complexity
7. number of workflows
8. migration volume
9. organizational change
10. training

A sensible approach is often to start with a clearly defined PLM problem rather than attempting to transform every product process simultaneously.

For example:

Phase 1: Product records and BOM management

Phase 2: Engineering changes

Phase 3: CAD and ERP integration

Phase 4: Supplier and quality workflows

The appropriate phases will differ by business.

PLM Implementation Checklist

Before selecting software, document the current product-development process.

Product Data

Identify where the following information is currently stored:

1. parts
2. BOMs
3. CAD files
4. drawings
5. specifications
6. revisions
7. supplier information

Change Processes

Map how engineering changes currently happen.

Identify:

1. who requests changes
2. who evaluates them
3. who approves them
4. how affected data is updated
5. how manufacturing and suppliers are notified

Existing Systems

List systems that may need integration:

1. CAD
2. PDM
3. ERP
4. MES
5. CRM
6. procurement
7. quality systems
8. supplier portals

Migration

Determine what historical information genuinely needs to move into the new PLM platform.

Migrating every file simply because it exists can create unnecessary cost and complexity.

Ownership

Decide who will own PLM administration after implementation.

A PLM system should not become dependent on a consultant for every routine workflow adjustment.

How We Evaluate PLM Software

HowToBuySaaS evaluates PLM products according to the product-development environments they are designed to support.

Product Data Management

We consider how the software organizes parts, product structures, specifications, documents, revisions, and other product records.

BOM Management

We look at support for structured and multi-level BOMs, revision control, collaboration, and product changes.

Engineering Change Management

A strong PLM platform should provide a controlled process for proposing, reviewing, approving, and implementing engineering changes.

CAD and Engineering Integration

For engineering-driven businesses, we consider compatibility with existing design systems and how naturally product information moves between engineering tools and PLM.

Workflow and Approvals

We evaluate whether product processes can be standardized without requiring excessive manual administration.

Supplier Collaboration

For businesses working with external manufacturers and suppliers, controlled information sharing and collaboration can be important selection criteria.

Integration

We consider how PLM connects with ERP, CAD, PDM, procurement, quality, and other business systems.

Implementation Complexity

Feature depth is not always an advantage.

We consider how much configuration, migration, training, and administration may be required relative to the needs of the intended buyer.

Scalability

The system should be able to support increasing product complexity, users, product lines, locations, and processes without requiring the company to replace its core product-data environment prematurely.

Pricing and Total Cost of Ownership

We consider software licensing alongside implementation, integrations, migration, training, and ongoing administration.

Questions to Ask Before Buying PLM Software

1. What product information are we trying to control?
2. How complex are our BOMs?
3. How many engineering users do we have?
4. How many non-engineering users need product information?
5. Which CAD systems do we use?
6. Do we already have PDM software?
7. Which system currently owns our BOM?
8. How are engineering changes managed today?
9. Do suppliers need access?
10. Do we need ERP integration?
11. Do we need quality-management workflows?
12. Are there industry-specific regulatory requirements?
13. Do we manufacture internally or through contract manufacturers?
14. Do we manage several product variants?
15. How much historical data needs migration?
16. Do we need cloud or on-premises deployment?
17. What integrations are mandatory?
18. How much customization is genuinely necessary?
19. Who will administer the platform?
20. How will users be trained?
21. What will implementation cost beyond software licenses?
22. What is the expected implementation timeline?
23. How easily can the system change as our processes evolve?
24. Can we start with one workflow and expand later?

These questions are more useful than beginning with a vendor comparison because they define what the PLM system actually needs to accomplish.

Frequently Asked Questions About PLM Software

What is PLM software?

PLM software manages product data and product-development processes across the lifecycle of a product.

It can include BOM management, product data, engineering changes, revisions, documents, suppliers, requirements, quality processes, and integrations with engineering and business systems.

What does PLM stand for?

PLM stands for Product Lifecycle Management.

What is the best PLM software?

There is no universal best PLM platform.

The right system depends on the company’s industry, product complexity, CAD environment, manufacturing model, team size, integration requirements, and implementation resources.

A hardware startup may prioritize a fast cloud implementation and straightforward BOM management, while a multinational manufacturer may require a much deeper enterprise PLM environment.

What is the difference between PLM and PDM?

PDM primarily focuses on product and engineering data, particularly CAD files, revisions, and related design information.

PLM covers a broader portion of the product lifecycle and can connect engineering data with BOMs, changes, requirements, suppliers, manufacturing, quality, and other processes.

What is the difference between PLM and ERP?

PLM generally manages the product definition and product-development processes.

ERP manages operational business processes such as procurement, inventory, manufacturing planning, costing, finance, and orders.

Product companies frequently integrate the two.

Is PLM only for large manufacturers?

No.

Cloud PLM and lighter product-data platforms have made lifecycle-management capabilities accessible to smaller manufacturers and hardware companies.

The amount of PLM functionality required should match the complexity of the product and organization.

What is BOM management?

BOM management is the controlled management of the parts, assemblies, quantities, revisions, and other information that define a product’s structure.

It is a core function of many PLM systems.

What is an engineering change order?

An Engineering Change Order, commonly abbreviated as ECO, is a controlled process used to authorize and document a change to a product or its associated information.

PLM software can manage the request, review, approval, affected items, revisions, and implementation of the change.

Does PLM software integrate with CAD?

Many PLM and PDM systems provide integrations with CAD software.

The depth of integration varies significantly, so engineering teams should verify support for their exact CAD environment before selecting a platform.

Does PLM integrate with ERP?

Many PLM platforms can integrate with ERP systems.

The integration is commonly used to transfer approved product, part, BOM, and release information from engineering into downstream operational systems.

Is cloud PLM better than on-premises PLM?

Neither model is automatically better.

Cloud PLM can reduce infrastructure requirements and simplify remote access and updates.

Some organizations may require greater control over deployment, integration, or data environments.

The correct choice depends on the organization’s technical, security, regulatory, and operational requirements.

How much does PLM software cost?

PLM pricing varies widely.

Costs may depend on users, roles, modules, integrations, deployment, and implementation requirements.

Businesses should calculate the total cost of ownership rather than comparing only software license prices.

How long does a PLM implementation take?

Implementation time depends on the complexity of the organization, workflows, integrations, customization, data migration, number of users, and scope of the project.

A focused cloud implementation for one workflow can be much simpler than an enterprise-wide replacement of an existing PLM system.

What industries use PLM software?

PLM is commonly used in industries including manufacturing, automotive, aerospace, electronics, industrial equipment, consumer products, retail, apparel, and medical devices.

The required functionality varies significantly between industries.

Do small manufacturers need PLM?

Not every small manufacturer needs a full PLM platform.

PLM becomes more valuable when BOMs, revisions, engineering changes, CAD data, suppliers, or product releases become difficult to control using spreadsheets and shared folders.

Compare PLM Software on HowToBuySaaS

Start with the product information or process that currently causes the most difficulty.

If engineers are struggling with uncontrolled BOMs and revisions, prioritize product-data and BOM management.

If changes reach manufacturing slowly or inconsistently, focus on engineering change management.

If CAD files are disconnected from the wider product record, evaluate PDM and CAD integration carefully.

If suppliers regularly receive outdated specifications, examine external collaboration and controlled access.

If information breaks when engineering hands a product to manufacturing, prioritize PLM-to-ERP integration and product-release workflows.

Then compare PLM platforms based on your industry, product complexity, engineering stack, implementation requirements, integration needs, and total expected cost.

The best PLM system is not the one that manages the largest number of processes. It is the one that gives your organization reliable control over product information and change without making product development unnecessarily difficult.
