Subclaims¶

q3 i2 Engineering team members scored significantly lower on both ONA dimensions than product design team members (d=0.496 X-axis, d=1.49 Y-axis), reflecting different KC approaches. → Ohsaki 2026 q3 i3 Product design team scored significantly higher on Y-axis than service design team (d=-2.12), reflecting greater focus on creating shared understanding. → Ohsaki 2026 q3 i1 Engineering team scored significantly higher on X-axis than service design team (d=0.79), reflecting engineers' focus on restructuring ideas versus service designers' information acquisition. → Ohsaki 2026

q3 · i2 · associational · r1

Regression analysis of ONA scores from three teams (N=27 speaker-phase units) during 30-minute wallet prototyping sessions. Engineering vs Product Design: "t(24) =2.52 , p<0.05 , d=0.496" on X-axis and "d=1.49" on Y-axis. Engineering vs Service Design: d=0.79 on X-axis. Product Design vs Service Design: d=-2.12 on Y-axis.

"Members of the Engineering Team were significantly lower on both dimensions than members of the Product Design Team: t(24) =2.52 , p<0.05 , d=0.496 along the X-axis and t(24) =5.46 , p<0.05 , d=1.49 along the Y -axis."
