PLM Software: Product Lifecycle Management explained simply

PLM software helps companies manage all information, processes, and data surrounding a product throughout its entire product lifecycle. PLM stands for Product Lifecycle Management, in German Produktlebenszyklusmanagement. It refers to the structured management of a product from the initial idea through development, design, manufacturing and use to service, further development or end-of-life.

PLM software plays a particularly important role in manufacturing companies, in mechanical and plant engineering, in the electrical industry, in medical technology, or in variant-rich production environments. Products are becoming more complex, development cycles shorter, and requirements for quality, documentation, and traceability are increasing. At the same time, development, purchasing, manufacturing, service and management must be able to access consistent product data.

A PLM software provides a central foundation for this. It helps to transparently organize product data, technical documents, CAD data, bills of materials, versions, changes, and release processes. In conjunction with an ERP system, product development and operational business processes can be more tightly linked.

What is PLM?

PLM stands for Product Lifecycle Management and describes the holistic handling of product information over the entire life cycle of a product. This includes all phases from the product idea through development, design, prototyping and manufacturing up to service, maintenance, further development, and end of life.

PLM is not only software but also an organizational approach. Companies define how product data is created, checked, released, changed, distributed and used. The goal is to create a reliable information base that all involved areas can access.

Key questions include: Which version of a component is current? Which bill of materials applies to manufacturing? Which technical changes have been released? Which documents belong to a product? Which requirements must be met? And how do relevant product data reliably reach purchasing, production, quality assurance, and service?

What is PLM Software?

PLM software is a digital solution with which companies centrally manage product data and product-related processes. It supports the organization of design data, documents, Bills of Materials, variants, approvals, changes, and workflows.

A PLM software typically offers functions for:

• Management of product data and technical documents
• CAD data management and CAD integration
• Versioning of drawings, documents and components
• Bills of materials management
• Change management
• Approval processes
• Collaboration between development, design and manufacturing
• Traceability of product decisions
• Integration with ERP-, PDM-, CAD-, and other systems

In this way PLM software helps to make product development more structured, transparent and efficient. It reduces the risk of working with outdated or conflicting product information and helps companies implement technical changes in a controlled manner.

Why is PLM Software important?

In many companies, product data arise at different places. Design drawings lie in the CAD system, Bills of Materials are maintained in spreadsheets, technical changes are coordinated by email, and manufacturing information is in the ERP system. The more complex products and processes become, the harder it is to keep track of things.

PLM software solves this problem by structurally bringing together product-related information. This makes clear which data are current, who made changes, which approvals have taken place, and which information is relevant for downstream processes.

The main objectives of PLM software are:

• Create transparency: Product data, versions, documents, and changes are traceably managed.
• Improve quality: Errors due to outdated data or unclear approvals are reduced.
• Facilitate collaboration: Development, design, purchasing, manufacturing and service work on a common information base.
• Control changes: Technical changes are reviewed, approved and implemented in a structured way.
• Shorten time-to-market: Better processes can reduce development and alignment times.
• Support compliance: Documentation, traceability and approvals can be better organized.
• Prepare ERP processes: Product data can be passed more specifically to manufacturing, purchasing and Materials Management.

What tasks does PLM Software take on?

The concrete scope of functions depends on the respective solution and the company's requirements. However, typical functional areas of PLM software are similar across many manufacturing companies.

Product Data Management

PLM software manages central product information such as items, components, assemblies, drawings, specifications, documents, and technical features. The goal is a reliable data base for development, manufacturing and other parts of the company.

CAD Data Management

In design, a lot of product-relevant information is created in the CAD system. PLM software or connected PDM systems help to manage CAD files in a structured way, control versions, and neatly assign technical documents.

Bill of Materials Management

Bills of materials describe which components make up a product. PLM software supports the management of technical bills of materials from development as well as the transfer of relevant information to downstream processes such as purchasing, production planning and manufacturing.

Versioning and Change Management

Products change over the course of their development and use. PLM software makes it traceable which version of a component, a drawing, or a bill of materials is valid. Technical changes can be requested, reviewed, approved and documented in a structured way.

Release Processes

Before product data are used in procurement or production, they often need to be checked and released. PLM software supports defined workflows so releases are traceable and carried out according to uniform rules.

Cross-Department Collaboration

Product development is rarely limited to a single department. Design, purchasing, production, quality assurance, service and management require different information. PLM software helps structure this collaboration and prevent information loss.

PLM, PDM and CAD: Where do the differences lie?

In connection with PLM software, the terms PDM and CAD also frequently appear. They are closely related, but describe different focus areas.

CAD

CAD stands for Computer-Aided Design. CAD systems are used to create technical drawings, models, and design data. They are especially important in development and construction.

PDM

PDM stands for Product Data Management. PDM systems focus on the management of technical product data, especially CAD files, drawings, documents and versions. PDM is thus often closer to design.

PLM

PLM is more comprehensive than PDM. While PDM mainly manages technical product data, PLM considers the entire product lifecycle. This includes, in addition to design and product data, processes such as changes, approvals, collaboration, compliance, manufacturing handover, service information and product further development.

Simply put: CAD creates product data, PDM manages technical product data, and PLM organizes the lifecycle of this product data across departments and processes.

PLM and ERP: Why the integration is critical

PLM and ERP perform different tasks, but should work closely together. PLM software mainly supports development, design, and product-related data processes. An ERP system controls central business processes such as purchasing, materials management, manufacturing, warehousing, sales, finance, and controlling.

In practice, both worlds meet no later than when a product idea becomes a producible product. Technical BOMs, item information, drawings, material data or change statuses must be handed over to operational processes. Only if this information is consistent can purchasing, production and warehousing operate reliably.

A good PLM-ERP integration helps avoid data integrity gaps. Product data from design and development can be reliably handed over to the ERP system. Conversely, information from manufacturing, purchasing or service can again provide important hints for product improvements.

PLM vs. ERP: What is the difference?

PLM and ERP are sometimes confused because both systems work with product and corporate data. The difference lies mainly in the focus.

PLM software focuses on the product lifecycle. It supports product development, engineering, technical documentation, versioning, changes and approvals.

ERP software focuses on planning and controlling business and operational processes. This includes purchasing, warehousing, materials management, manufacturing, sales, service, finance and controlling.

For manufacturing companies, it's not a question of whether PLM or ERP is more important. What matters is that both systems work together cleanly. PLM provides controlled product data, ERP ensures their operational execution in procurement, manufacturing, delivery and invoicing.

PLM in manufacturing

In manufacturing companies, PLM is particularly relevant because product data is directly linked to production processes. Faulty drawings, outdated bills of materials, or unclear change statuses can lead to rework, incorrect orders, production delays, or quality problems.

Typical challenges in manufacturing are:

• many product variants
• complex bills of materials
• frequent technical changes
• close coordination between design/engineering and manufacturing
• high requirements for quality and documentation
• integration of CAD-, PDM-, PLM- and ERP-systems
• traceability of approvals and versions

PLM software helps companies manage this complexity more effectively. It creates structures for product data and ensures that information enters manufacturing in a controlled way.

PLM software in mechanical and plant engineering

In mechanical and plant engineering, products are often customized, technically demanding and project-based. Job shop and contract manufacturing, variants, customer-specific adaptations, and long product life cycles place special demands on product data and change processes.

PLM software can help here by organizing design data clearly, making technical changes traceable, and improving coordination of information between development, project management, purchasing and manufacturing.

Especially when customer requirements are adjusted during a project, clean versioning is important. Companies must know which drawing, which bill of materials, and which change status apply to which order.

Engineering Change Management: Managing changes safely

Technical changes are a daily part of product development. Components are adjusted, materials replaced, suppliers change, or customers request a different specification. Without structured change management, such adjustments can quickly lead to errors.

PLM software supports Engineering Change Management by documenting change requests, reviews, approvals, and affected data in a traceable manner. This shows which products, assemblies, bills of materials, drawings, or processes are affected by a change.

In conjunction with the ERP system, it is especially important that approved changes reliably reach purchasing, manufacturing and warehousing. This helps avoid incorrect orders, outdated manufacturing documents, or unclear production foundations.

The Digital Thread in Product Lifecycle Management

The term Digital Thread describes the seamless connection of product data across different systems and process steps. In the PLM context: information from development, engineering, manufacturing, quality, service and other areas is not viewed in isolation but linked along the product lifecycle.

A seamless Digital Thread helps companies trace product information more effectively. Changes, decisions and data states can be represented more transparently across the lifecycle. Especially for complex products, this can create important advantages for quality, service and further development.

Advantages of PLM software

The benefits of PLM software arise mainly where a lot of product data, technical documents, versions and departments come together. A structured PLM solution can help companies better connect product development and manufacturing.

• Central product data: Product information is managed in a structured way and easier to find.
• More transparency: Versions, approvals and changes are traceable.
• Better collaboration: Development, engineering, purchasing, manufacturing and service work with more consistent information.
• Fewer errors: Outdated drawings or unclear data states can be avoided.
• Faster development processes: Coordinations and approvals can be organized more efficiently.
• Higher quality: Product data and changes are processed more controllably.
• Better ERP integration: Relevant product data can be specifically handed over to operational processes.
• More traceability: Decisions and changes remain documented.

When is PLM software worthwhile?

PLM software is particularly worthwhile when product data become more complex and involve multiple departments or sites. The more variants, technical changes, documentation obligations, and interfaces exist, the more important structured management of the product lifecycle becomes.

Typical indicators for PLM need are:

• CAD data, BOMs and technical documents are managed in different systems.
• It is not always clear which version of a document is current.
• Changes are coordinated via email, Excel or informally.
• Design and manufacturing do not work on the same data basis.
• Product variants are increasing.
• Approval processes are hard to trace.
• Technical changes cause errors in purchasing or production.
• Documentation and compliance become more time-consuming.

In such situations, PLM software can help structure product information better and improve collaboration between development and operational areas.

PLM software and Abas ERP

Abas ERP is an ERP solution for medium-sized manufacturing companies. The software supports central business areas such as purchasing, sales, manufacturing, warehousing, service, finance, controlling and management in a single integrated system.

For connecting ERP and CAD/PDM/PLM, Abas offers a process-oriented system integration via the CAD/PDM-Connector. This allows companies to connect CAD, PDM, or PLM solutions with Abas ERP and better embed product-related data in downstream ERP processes.

This integration is particularly relevant when technical product data from development and design are to be used in purchasing, materials management, manufacturing, or service. In this way, companies can transfer product information more structurally into operational processes and improve the continuity between engineering and ERP.

Abas ERP also supports manufacturing companies with comprehensive functions for central processes along the value chain. These include, among others, purchasing, sales, manufacturing, warehousing, service, finance, controlling and management. As a Cloud ERP or on-premise solution, Abas ERP can be adapted to different requirements and IT strategies.

What should companies look for when selecting PLM software?

The choice of PLM software should be guided by the product data, processes and system landscape of the company. It is not only the features but also how well PLM can be integrated into existing processes.

Important selection criteria are:

• CAD and PDM integration: The solution should support existing design processes effectively.
• ERP integration: Product data must be able to be handed over to operational processes in a controlled manner.
• Bill of Materials management: Technical and manufacturing-relevant BOMs should be managed cleanly.
• Change management: Changes should be auditable, reviewed, approved, and implemented in a traceable manner.
• Versioning: Documents, drawings and product data must be clearly versioned.
• Usability: The solution should be accepted by development, engineering and other departments.
• Scalability: The software should grow with increasing product and process complexity.
• Process support: Workflows, approvals and responsibilities should be clearly modeled.

Common mistakes in PLM projects

PLM projects involve not only software but also processes, roles and data quality. Problems often arise when companies treat PLM as a pure IT implementation.

Common mistakes are:

• unclear responsibilities for product data
• lack of coordination between development, manufacturing and ERP owners
• incomplete or inconsistent master data
• too complex approval processes
• missing interface strategy
• insufficient involvement of future users
• unclear rules for versioning and changes

Successful PLM projects therefore begin with a clear analysis of existing processes. Companies should define where product data originates, who uses it, which approvals are required and how the handover to ERP processes should occur.

Conclusion: PLM software connects product development and manufacturing

PLM software helps companies manage product data in a structured way across the entire lifecycle. It creates transparency about drawings, bills of materials, versions, changes and approvals and supports collaboration between development, design, manufacturing and other areas.

Especially for manufacturing companies, the integration of PLM and ERP is decisive. While PLM organizes the product-related data base, ERP controls the operational processes in purchasing, materials management, manufacturing, warehousing, sales and controlling. With Abas ERP and the CAD/PDM integration, companies can connect these worlds better and embed product data more consistently into their business processes.
