A list of definitions of terms used in this document.
- Arcadia refers to the MBSE method supported by Capella.
- The Eclipse Capella Industry Consortium is referred to as the Capella IC in this document
- Capella Project (“Capella”) refers to the Polarsys project hosted at
- Capella refers to the Polarsys Solution consisting of a ready-to-use and well-tested
package with the Capella Project and its open source dependencies, as described at
- Capella Add-ons refers to the plug-ins which extends the scope and feature set of Capella,
including connectors, and which are not included in Capella itself.
- Capella Studio refers to the solution consisting of Capella and its SDK which is used to
- Model Based Systems Engineering (MBSE) refers to model-based systems design and
- Suppliers refers to any organization providing commercial software related offerings,
including proprietary products, professional services, training, and mentoring, related to
the technologies within the scope of this consortium.
To fulfill the overall MBSE vision, industrial users needs a mature, full-featured,
sustainable solution which can be widely distributed as an open source alternative to existing
proprietary modeling tools.
The Capella tools, in association with the Arcadia method, can meet this need.
The Capella ecosystem will include companies developing complex systems and software,
suppliers providing offers on top of Capella and academics researching MBSE themes. A place to
foster collaboration, share investments, exchange best practises, and to leverage Open
Innovation will ensure a vibrant ecosystem that will enable the co-development of new MBSE
The Capella IC aims to host the Capella Ecosystem stakeholders in a vendor neutral way,
organized by an open governance model.
The main goal of the Capella IC is to make Arcadia the leading system engineering method and
Capella the leading MBSE tool. Other key goals are in the following thematic areas:
- Share MBSE experiences and case studies among consortium members to enable broad adoption
of Capella and Arcadia in operational projects.
- Establish a technology watch service to help members leverage innovation in Capella and
- Keep up-to-date with new and noteworthy, future improvements, success stories, and user
- Organize private exchange workshops between members
Joint development financing
- Coordinate investments from consortium members in the different aspects of the overall
MBSE solution to reduce development time, risk, and costs, and to maximize ROI
- Capture, consolidate, and manage requirements from the different consortium members and
- Define development priorities based on consortium members requirements/needs
- Discuss the roadmap among users and contributors
- Operate a transparent process supported by tools.
- Promote the use of Capella as a leading industrial MBSE solution
- Provide materials to explain the value of Capella and Arcadia to executives and managers
- Provide a focal point for organizing collaboration and creating partnerships among
suppliers, end-users, and research/academia
The initial areas of work for the Capella IC include:
- Capella Studio
- Underlying technologies and plug-ins used by Capella and Capella Studio
- Capella Add-ons
Additional areas of work may be defined in the future by the Steering Committee of the IC.
The scope of the Capella IC includes the following key modeling processes:
- Definition of the Problem - Customer Operational Needs Analysis
- Formalization of system requirements - System Needs Analysis
- Development of System Architectural Design - Logical Architecture (Notional Solution)
- Development of System Architecture - Physical Architecture
- Formalize Component Requirements - Contracts for Development and IVVQ (Integration
Validation Verification Qualification)
- Co-Engineering, Sub-Contracting and Multi-Level Engineering
- Adaptation of Arcadia to support new dedicated Engineering Domains and to improve
integration capabilities with other tools
Summary of Membership Classes and Membership Fees
Membership is based on a one year renewable commitment. As Capella IC is a neutral and
transparent consortium, the rules for joining are clearly defined by the Working Group
participation agreement and the Eclipse membership agreement.
As the Capella IC is a sub-group of the Polarsys Working Group, and as Polarsys itself is a
working group of the Eclipse Foundation, there are two additional membership requirements for
joining the Capella IC:
- Eclipse Solution membership as a minimum requirement, in compliance with the Eclipse
bylaws and processes
- Polarsys membership, in compliance with the Polarsys charter
All Capella IC members must pay both Eclipse Membership fees and Polarsys WG Membership fees.
No additional fees are mandatory to join the Capella IC.
Each year, Polarsys members are entitled to allocate a pre-determined portion of their
membership fees to ICs and Common Activities. To join the Capella IC, a minimum 20% of this
pre-determined portion, must be allocated to the Capella IC.
The fees to join the Capella IC are currently USD 0. Fee changes are at the discretion of the
Capella Steering Committee.
The membership classes of the Capella IC are designed to reflect the varied interests of the
members. The membership class of each Capella IC member is confirmed once per year.
Driver members want to influence the development of Capella and be an integral part of the
group of organizations that govern the development of the open source MBSE solution. They
invest a substantial amount of resources to sustain the Capella IC activities and contribute
to the development of the open source technologies.
Typical Drivers members are organizations that use MBSE solutions at the core of their
development process and who consider Capella as a strategic asset.
Each Driver member must document annually a minimum investment in the Capella IC activities
such as allocation of internal developers, features outsourcing, maintenance and support
contribution, marketing. These activities do not include investments for internal deployments
within the members’ teams or for private customizations. The minimum annual amount is
$50 000. The Steering committee is responsible for the analysis and approval of the annual
Participant members participate in the development of the Capella ecosystem. They contribute
to the development and adoption of Capella according to their roles, such as the development
of viewpoints for tools providers, participation at conferences, or providing requirements or
user experiences for end-users.
Research/academia members are Universities and research organizations that want to
participate in the development of the overall MBSE solution based on Capella. Their
contributions take the form of addressing various relevant research topics, using Capella for
teaching/training purposes, and contributing to the overall development of the ecosystem.
