- Kev sib thooj tuaj yeem muaj txiaj ntsig zoo rau kev sib txuas lus, qhov chaw mus ntsib (yog tias tsim nyog), thiab logistical vim li cas, tshwj xeeb tshaj yog rau prototyping lossis kev xav tau ceev.
- Kev sim & Kev lees paub: Lawv puas muaj cov kev pabcuam kuaj hauv tsev (kev sim quab yuam, kev sim qaug zog, cov ntaub ntawv tsom xam) kom validate caij nplooj ntoos hlav kev ua tau zoo tiv thaiv koj specifications?
Tswv yim: Pib los ntawm kev tiv tauj 3-5 manufacturers uas zoo li zoo haum. Qhia koj cov lus qhia ntxaws ntxaws, thiab ntsuam xyuas lawv qhov kev teb, engineering cov lus nug, thiab clarity ntawm quotes. Qhov kev sib tham thawj zaug no tuaj yeem qhia koj ntau yam txog lawv cov kev tshaj lij thiab kev tsim nyog.
