Main challenges:

- Development of new product family (passenger multiple unit) started

- Development team distributed over different sites in Europe

- Product with complex functional vehicle architecture

- Many variants to be derived from product family

Apply MBSE & SCRUM to

master complexity and meet quality, time and cost targets

INITIAL POSITION & OBJECTIVES

Modeling of large complex systems such as

rolling stock systems requires an excellent

coordination of the modelling team

APPLIED TOOL CHAIN


**no links beween work item in RTC and model element/requirement in Magic Draw/DOORS

✓ Supports distributed project teams

(web based client)

✓ Provides SCRUM templates, graphical

Kanban boards and sprint/project

burndown charts

✓ Allows the customization of the

workflow supporting the modeling

methodology

✓ Available at BT

✓ Requirements artifacts in DOORS and

model elements in MagicDraw are

linked **

CONNECTION BETWEEN WORK ITEMS AND MODELS


Modelers are responsible to update the

tickets in the Kanban Board according to

the status of models and reviews. In this

way:

✓ Connections between the work items

and models are created

✓ The MBSE Team’s feeling of success

and motivation is increased ;-)

SCRUM4MBSE improved collaboration but also increased the team

spirit by sharing small and regular successes throughout the sprints

RESULTS

BENEFITS OF MODELING “AGILE”

Benefits of SCRUM

✓ Improvement of planning quality already after

the first sprint

✓ Continuous visibility of the impact of deviations

from the planning and thus possibility to react

fast

✓ Cost target, delivery due date and quality goal

achieved

Benefits of MBSE

✓ Increase of requirement specifications quality,

e.g. missing requirements added, wrong

allocation of requirements corrected and

inconsistencies between requirements on

different levels resolved

✓ Finalize stable high quality functional

architecture as a base for further development

of variants out of the product family
