Validierungsaktivitäten

I’m not sure what specific term you want me to cover, since “Validierungsak...” is incomplete. Could you please confirm the full term or provide the intended context? For example, you might mean:

- Validierungsakt (an act of validation) in legal or regulatory contexts

- Validierungsaktion (a validation action) in IT or data processing

- Validierung (validation) as a general concept in software quality assurance or data integrity

If you clarify the term and the target audience (German-speaking readers, technical or general audience), I will write a concise, neutral wiki-style article in plain text under 300 words.
