Adoption View

Welcome to the Modular Engineering (ME) KIT Adoption View. This view provides business value, strategic benefits, and use cases for business stakeholders and decision-makers.

Vision & Mission​

Vision​

To enable a modular and federated engineering ecosystem where complex systems can be collaboratively developed by multiple partners – efficiently, transparently, and securely. This empowers organizations to innovate faster, reuse proven solutions, and integrate interdisciplinary expertise across the Ecosystem.

Mission​

The Modular Engineering KIT establishes a common framework for modularized, data-sovereign product/system development.

It provides standardized semantics and interface definitions that allow engineering activities (projects) to be modeled, distributed (utilizing EaaS), and coordinated/executed across organizational boundaries. By structuring and interlinking engineering activities Modular Engineering ensures that every design, task, and decision is traceable and harmonized.

By doing so, ME becomes the operational runtime for engineering — the layer where conceptual designs, processes, and collaboration converge into tangible, traceable engineering results.

Business Value​

Modular Engineering can add substantial strategic and operational value to the Catena-X ecosystem and its participants through:

  1. Federated Engineering Collaboration – Complex development programs are structured into standardized $^1$, interoperable modules that can be orchestrated among the ecosystem participants. This takes into account scalability, alignment, and traceability across the entire engineering lifecycle.
  2. Requirement Alignment & Traceability – Engineering objects and activities are (and consistently remain) connected to explicit requirements, enabling transparent validation, verification, and compliance tracking.
  3. Process Efficiency & Modularity – Standardized process patterns and reusable engineering modules reduce redundant work, shorten development cycles, and improve overall quality.
  4. Ecosystem Scalability & Resilience – Modular Engineering supports a scalable collaboration model that allows quick partner onboarding, dynamic resource allocation, and flexible reconfiguration of engineering networks in response to market demands.
  5. Data Sovereignty & Intellectual Property Protection – Through dataspace principles, partners retain full control over their engineering data and models while enabling the selective, trusted exchange of information.
  6. Outlook: Foundation for AI-Enhanced Engineering – Standardized structures and data interoperability form the foundation for advanced analytics and AI-assisted decision-making in engineering workflows.

$^1$ as much as necessary, as little as possible

Summary of Business Benefits​

For Engineering Project/Product Owners (OEMs, System Integrators):

  • Clear visibility into progress and interdependencies across modularized development units.
  • Federated control of data, models, and configurations across suppliers.
  • Simplified integration and validation processes through harmonized interfaces.
  • Reduced program risk through standardized, traceable collaboration.

For Engineering Service Providers (especially SMEs):

  • Easier access to projects with clear scope, interface definitions, and deliverables.
  • Opportunity to demonstrate specialized skills through standardized capability descriptions.
  • Reduced rework and improved project predictability through harmonized workflows.

For the Entire Ecosystem:

  • Improved interoperability between engineering tools and data sources.
  • Enhanced ability to reuse knowledge, modules, and engineering artifacts across projects.
  • Strengthened European competitiveness through standardized digital collaboration.

Use Case Context​

Industry Challenge​

Modern product development increasingly depends on distributed, multidisciplinary teams working across different organizations and digital environments. However, current engineering practices are often siloed, with inconsistent data formats, redundant tasks, and limited process/workflow visibility. The lack of modularization makes scaling and collaboration inefficient, especially for specialized SMEs.

Without a standardized foundation for project breakdown, interface definition, and lifecycle control, cross-company development efforts are prone to misalignment, delays, and costly integration issues.

The Solution​

Modular Engineering establishes a unified method for structuring, managing, and integrating engineering activities across company boundaries. It provides:

  • A common semantic foundation for project scoping and orchestration for all engineering stakeholders.
  • A modular project architecture that enables the decomposition of complexity into manageable, interoperable elements.
  • A trusted collaboration space that respects data sovereignty and intellectual property.

This enables the orchestration of federated development ecosystems, where each participant contributes specialized expertise while maintaining full control

Business Processes​

  1. Requirements Definition – A development (with demand for modular engineering activities) is initialized by a set of requirements.
  2. System Decomposition – A complex system (subject of development that meets the requirements) is divided into a modular set of objects (subsystems) for collaborative engineering.
  3. Project modeling – Each object is linked to corresponding engineering activities and phases.
  4. Interface Specification – Define clear data, model, and process interfaces between modules.
  5. Concurrent Development – Execute modular engineering tasks while maintaining consistency through synchronization of product and process representations.
  6. Integration & Validation – Merge subsystem results and validate against defined interfaces and requirements.
  7. Version Control & Feedback – Manage iterative updates and improvements through traceable versioning.

Semantic Models (outlook)​

Modular Engineering complies to/defines several semantic models. Examplary suggestions are:

  • Bill of Engineering Processes (BoE) – A BoE data model defines a set of mandatory properties to provide information about the engineering process and enables the common understanding required for engineering task orchestration.
  • Engineering Status Tracking – Get status information about engineering tasks to enable tracking of progress & task management.
  • Bill of Requirements – Represents the functional and non-functional requirements towards the product and its engineering process.

Deliverables: Jointly refined model specifications and GitHub repository links.

Functional Role and Ecosystem Integration​

Modular Engineering acts as a collaboration-orchestration KIT within the Tractus-X engineering ecosystem, providing the framework for federated, collaborative development. Its functionalities are designed to connect and synergize with other Tractus-X KITs and overarching data space conecpts, creating an integrated engineering value chain:

1. Connection with Product Portfolio Management (PPM)​

  • Modular Engineering builds and orchestrates concrete engineering procedures (HOW) based on the elements (processes & products) provided by PPM (WHAT).
  • More precise: A modular development is composed of a set of engineering activities (processes/tasks) and corresponding objects (products/sub-systems) that are instantiated under a PPM-managed lifecycle. In Modular Engineering, they are selected, combined and orchestrated in a way so they meet concrete requirements.
  • Feedback on progress, design maturity, and engineering performance is continuously reported back to PPM.

[!NOTE] The Product Portfolio Management KIT (Sandbox State) is currently under development for release 26.06. For an overview on the current content please refer to the release planning issue Product Portfolio Management (PPM) Use Case Information.

2. Connection with Engineering as a Service (EaaS)​

  • Modular Engineering defines what is to be done (tasks, interfaces, modular objects), while Engineering as a Service (EaaS) defines who performs it.
  • The EaaS KIT leverages the task definitions from Modular Engineering to identify, match, and contract suitable partners/service providers. The results are fed back into ME’s execution environment and utilized within the project context.

3. Relationship with overall Data Sovereignty and Governance​

  • Modular Engineering builds on the Catena-X principles of data sovereignty and usage policy enforcement, ensuring that engineering data shared between partners adheres to defined access rights and contractual terms.

4. Alignment with Digital Twin and Product Lifecycle KITs​

  • Modular Engineering utilizes Digital Twin frameworks to represent structured engineering information (requirements, process & product data etc.) - of course.
  • The KIT complements lifecycle management by linking design data with manufacturing and operational twins, ensuring traceability across the product’s lifecycle.

Standards​

Supported Standards​

ME aligns with and contributes to Catena-X and IDSA standards for interoperability and data sovereignty. The interconnection with existing standards and the scoping of additional standards are yet to be completed.

Tutorials & Resources​

To be developed for the “Graduated” stage. Tutorials can demonstrate:

  • How to define requirements and link them to a set of development objects and processes.
  • How to model and manage relationships and dependencies between components and activities.
  • How to define, assign, and execute modular tasks.

Currently, the creation of tutorial content is not planned.

Whitepaper (outlook)​

A Modular Engineering Whitepaper could elaborate on:

  • The conceptual foundations of modularized engineering within Catena-X.
  • The architecture and lifecycle of Virtual Development Objects.
  • Governance models for federated engineering networks.
  • Semantic standards supporting interoperability and lifecycle traceability.

Currently, the creation of a whitepaper is not planned.
