Use in order to + infinitive to explain the purpose of an action: ‘They work hard in order to make the company successful.’
Normally, the subject of both actions is the same: they work and they make.
When the second part has a different subject, use so that + subject + verb: ‘They work hard so that the company can be successful.’
We can also use in order for + noun/pronoun + to + infinitive, but this is more formal: ‘They work hard in order for the company to be successful.’
