Langzeitverlässlichkeit

The term you provided appears truncated. Could you please provide the full term or clarify the intended topic? For example, it could refer to topics such as Langzeitverlauf (the long-term progression of a disease or process), Langzeitverlegung (long-term relocation), Langzeitverlust (long-term loss), or another related concept. If you specify the exact term or domain (medicine, sociology, technology, etc.), I can write a concise, neutral wiki-style article under 300 words.
