When does it start?
2
When does the NPI process start?
3
Sure, so before NPI starts you've got your typical product development phase.
4
So it's very important that product development is done thoroughly and
5
that you are doing mechanical and electronic design for a consumer product
6
and prototyping to a level that verifies that your product works and it has value-add as you anticipated.
7
So that really needs to happen before you get into NPI.
8
So I would say you would need a list of documentation
9
from an engineering point of view before you could say that you're ready for the NPI phase.
10
So this includes translating the requirement into very specific requirements, making it as specific as possible,
11
getting the product design firmed up and frozen basically
12
and also getting some prototypes that are relatively close but maybe not made with production tooling,
13
not made with the same processes as would be in production
14
but something that already looks more or less the same as the desired product and already works right, it already has to be functional.
15
Yeah, it should have all the key features.
16
Most likely there's going to be some known issues that need to be resolved.
17
But as you said, the product requirements document should be established
18
and it should be meeting 90% of that and then any known issues should be documented.
19
And then the NPI phase can begin.

シャドーイングとは?英語上達に効果的な理由

シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
