'Durchführen' (to carry out / to guide through) is a separable verb. The prefix 'durch-' comes at the end in main clauses. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Die Firma führt eine Mitarbeiterbefragung durch.
The company is carrying out an employee survey.
The verb 'durchführen' (to carry out) is mainly used in formal, official, or scientific contexts. It often sounds bureaucratic or planned.
Die Polizei wird morgen Verkehrskontrollen durchführen.
The police will carry out traffic checks tomorrow.
'Durchführen' (to carry out) is often combined with nouns that describe a planned action. Common combinations are: 'eine Studie durchführen' (to carry out a study), 'ein Experiment durchführen' (to carry out an experiment), 'eine Reparatur durchführen' (to carry out a repair), or 'eine Veranstaltung durchführen' (to hold an event).
Die Wissenschaftler führen ein wichtiges Experiment durch.
The scientists are carrying out an important experiment.
You can recognize the literal meaning 'jemanden durch einen Ort leiten' (to guide someone through a place) by the fact that there is a subject that leads and an object that is being led. The preposition 'durch' is often repeated in the sentence to describe the route.
Der Förster führte uns sicher durch den dichten Wald durch.
The forester guided us safely through the dense forest.
to lead
'führen' and 'durchführen' look similar and can both have to do with leading or guiding. Use 'führen' when someone brings a person to a place or leads a group, company, or department. Use 'durchführen' mostly when you actually carry out and organize a plan, an event, a test, or a task. In the meaning 'to guide through a place or process', they are closer to each other. There is a risk of confusion because 'durchführen' contains the word 'führen'. But a meeting is usually 'durchgeführt' (carried out), while a department is 'geführt' (led / managed).
