    """
    Example request flow for enterprise generative AI applications
    """
    # Preprocess and validate input
    sanitized_input = security_layer.sanitize(user_input)
    validated_input = validation_layer.validate(sanitized_input)

    # Retrieve relevant context
    context = context_retriever.get_context(
        validated_input,
        user_context=context_data.user_context,
        enterprise_knowledge=context_data.knowledge_base
    )

    # Construct prompt with guardrails
    prompt = prompt_manager.construct(
        validated_input,
        context,
        safety_guidelines=model_config.safety_rules,
        tone_guidelines=model_config.enterprise_tone
    )

    # Generate with monitoring and fallbacks
    try:
        response = model_orchestrator.generate(
            prompt,
            model=model_config.primary_model,
            params=model_config.parameters,
            timeout=model_config.timeout
        )
    except Exception as e:
        response = fallback_handler.process(e, validated_input, context)

    # Post-process and validate output
    validated_response = output_validator.validate(response)

    # Log for improvement
    feedback_collector.log_interaction(
        user_input,
        prompt,
        response,
        metadata=context_data.metadata
    )

    return validated_response
