Situation

Designers of seven different disciplines make discipline-specific partial designs. As a team, they align their partial designs on a regular basis to form an integral design. When aligning their partial designs, the designers discover design conflicts, which they resolve by changing their designs.

Challenge

[Improving a design service, Advancing a design team] How can designers from different disciplines reduce the number of design conflicts between their partial designs?

gps_fixed

Ambition

[Time, Cost] Spend less time on discovering and resolving design conflicts, which results in less cost. This is desirable, feasible, and viable.

Assessment

Competitive position

[Weakness] Designers of different disciplines are unaware of conflicts arising between their partial designs.

report_problem

Problem

[System] To reduce the number of design conflicts between partial designs, designers from different disciplines need to share design objects, relations, and models when created and updated. This capability is missing. Designers can develop it, and its nature is explicit. Prognosis:

  • Unfavorable without intervention.
  • Favorable after an intervention.

Concept

[System] Adapt the way of working to prevent design conflicts between partial designs from arising.

Intervention

Step 1. Define a design ontology: have a knowledge engineer interview designers to extract meta-knowledge of design objects, relations, and models together making up an integral design.

Step 2. Create a meta-model of design: have a knowledge engineer represent the defined design ontology in a digital repository.

Step 3. Teach designers how to use a digital repository while designing: have a knowledge engineer train designers.

Series aircraft design

description

Situation

Junior designers struggle to design a successor. Progress is slowing down whenever there are no senior designers looking over their shoulder, or to spar with them.

Challenge

[Improving a design service, Advancing a design team] What can junior designers learn from senior designers to design a successor?

Ambition

[Time] Junior designers design a successor more quickly. This is desirable, feasible, and viable.

Competitive position

[Weakness] Unlike senior designers, junior designers do not know well how to design a successor.

report_problem

Problem

[System] What junior designers can learn from senior designers to design a successor is to make use of the design rationale of earlier aircraft in the same series. This capability is valuable but not organized: junior designers do not have it. They can develop it, and its nature is implicit. Prognosis:

  • Unfavorable without intervention.
  • Favorable after an intervention.

Intervention

Step 1. Define how to make use of the design rationale of earlier aircraft in the same series: have a knowledge engineer interview senior designers to extract knowledge of the way of working to retrieve, reuse, revise, and retain design rationale.

Step 2. Transfer knowledge of how to make use of the design rationale of earlier aircraft in the same series: have senior designers train junior designers in the way of working.
