Model-based Conceptual Design Working Group (MBCD WG) Charter
The purpose of this working group is to advance the body of knowledge and practice of systems engineering (SE) through the development and application of model-based systems engineering (MBSE) methodologies to the Exploratory Research and Concept stages of systems engineering.
Develop best practice for model-based conceptual design
- Enhance the practise of problem definition and identifying capability needs
- Develop modelling practise in support of Exploratory Research and Concept Stage
Activities cover current and future model-based conceptual design theory, practice and education. The working group's focus is on the Exploratory Research and Concept Stages of the generic life-cycle defined by INCOSE1. However, the working group will also consider how model-based conceptual design influences and is influenced by other life-cycle stages.
Model-based Conceptual Design
Model-based Conceptual Design (MBCD) is the application of MBSE to the Exploratory Research and Concept Stages of the generic life?cycle defined by INCOSE and more specifically to the following activities:
i. Identify stakeholders' needs
ii. Explore ideas and technologies
iii. Refine stakeholders' needs
iv. Explore feasible concepts
v. Propose viable solutions
The main MBCD outputs, listed below, summarise the generic products from the first two technical processes defined by INCOSE1. These technical processes are also depicted in Figure 1.
i. Stakeholder needs
ii. Concept documents, including the concept of operations and support.
iii. Stakeholder requirements specification
iv. Measures of effectiveness
v. System Functions and System Functional Interfaces
vi. Key performance parameters
vii. One or more System Conceptual Designs
viii. System analysis including trade studies to identify preferred concepts
ix. System requirements specification incorporating measures of performance
x. Validation and verification Criteria
Figure 1: INCOSE1 Systems Engineering ï¿½ Initial Technical Process Steps
Following a recommendation by INCOSE's Community Advisory Board2, the MBCD WG will, into the future, explore the application of the MBCD advances identified in the Exploratory Research and Concept Stages to the Validation Technical Process of the generic life?cycle defined by INCOSE1.
Member Skills and Expertise
Members should have a sound understanding of systems engineering, and expertise in model?based systems engineering, and a willingness to learn and advance the MBCD body of knowledge and practice. Researchers, practitioners and educators from the following domains, to the competency level of at least practitioner, act as examples of the expertise and skills required:
Systems Engineering Technical Skills
i. Stakeholder needs and requirements elicitation and definition
ii. Requirements analysis
iii. Requirements verification and validation
iv. Model-based systems engineering
Systems Engineering Project Skills
i. Project planning
ii. Project assessment
iii. Project control
i. Legal and policy
ii. Business analysis
iii. Soft systems analysis
iv. Systems thinking
v. Holistic lifecycle consideration
Membership, roles and responsibilities
The working group is structured with a steering group and activity teams.
The steering group consists of:
i. Chair ï¿½ Provide direction to, and be responsible for, the leadership of the MBCD WG
ii. Co-chairs ï¿½ Support the chair leading the MBCD WG and serve as chair in absence of the chair
iii. Members ï¿½ Support the activities of the MBCD WG steering group
Individual teams will be responsible for tackling specific challenges and issues. The teams consist of:
i. Lead - Provide leadership of team tackling specific challenges and issues
ii. Members - Support the team
Related working groups
It is desirable that the following INCOSE working groups should be engaged:
i. Requirements working group
ii. Systems of systems working group
iii. MBSE Initiative ï¿½ challenge teams and activity teams
iv. Tools integration and interoperability working group
The following are maintained on an ongoing basis by the steering group:
i. Working Group Charter
ii. Working Group strategy
iii. Working Group membership
iv. MBCD WG promotional material, including website and discussion forum
v. MBCD WG progress summary
The following are to be delivered by the teams:
i. Annual participation in the MBSE symposium, focusing on model-based conceptual design
ii. Description of the challenges and issues the MBCD WG could address, along with proposed selections and approaches
iii. MBCD WG activities roadmap
iv. Establishment and maintenance of an MBCD discussion forum
v. MBCD handbook (future)
vi. Half-yearly progress reports
The steering group will meet at least quarterly.
The individual teams will meet regularly and report to the steering group half-yearly.
Communicate via electronic media, including website, discussion forums, email and telecom.
Measures of success
Measures of success include:
i. Membership of activity teams
ii. Deliverables from activity teams
iii. Contributions to discussion forum
iv. New and updated MBCD practice products
v. Conference, symposiums and journal contributions
vi. MBCD symposiums organised
The MBCD WG will submit resources requirements as required. Resources required may include meeting facilities, teleconferencing, and publication costs.
This Charter will remain in effect until rescinded by the duly authorised INCOSE representative.
