About にもとづいて

In order to say that one thing is 'based on' another in Japanese, the expression (もと)づいて will be used. This is a combination of the case marking particle に, the う - Verb, (もと)づく 'to originate from', and the conjunction particle て. This expression regularly highlights some kind of judgement/conclusion that the speaker has made, using (A) as their base.
To use (もと)づいて, put the noun (or noun phrase) that you would like to identify as a 'basis' before (もと)づいて, and then express your judgment/conclusion in part (B) of the sentence.
  • クライアント指示(しじ)(もと)づいて編集(へんしゅう)しておきました。

  • 以前(いぜん)成功(せいこう)した計画(けいかく)(もと)づいて(あたら)しい計画(けいかく)()ようと(おも)っています
    I am thinking of making a new plan based on the previous successful plan.
Alternatively, the past form of (もと)づく may be used when connected directly to a second noun. (A) に(もと)づいた (B) directly expresses that (B) is based on (A).
  • (わたし)実話(じつわ)(もと)づいた映画(えいが)()です
    I like movies based on true stories.
  • 来週(らいしゅう)までに、アンケート(もと)づいたグラフ作成(さくせい)てください
    By next week, please make a graph based on these surveys.
Fun Fact
The kanji (もと) is fairly accurately translated as 'foundation', and is regularly used to highlight things that 'stem' from something. Due to this, (もと)づいて may also be used to identify things that are 'produced from (A)', 'created from (A)', or 'invented based on (A)'.

    I am having some trouble understanding the distinction between this point and の下で – for example, in the sample sentence ちゃんと計画に基づいて、動いてください, would ちゃんと計画のもとで、動いてください not have the same meaning?
