How Is AI Modeling Implemented in CRM Across Different Industries Over the Past Five Years? Based on a review of the selected literature, the implementation of Artificial Intelligence (AI) models in Customer Relationship Management (CRM) shows considerable variation, depending on the characteristics of each industry and its specific objectives. In this review. AI-CRM implementations are classified into 13 major sectors: telecommunications and communication, e-commerce, retail, credit and insurance, banking, research, online transportation services . , advertising and consultancy, information technology, academic administration, hospitality, business-to-business (B2B), and manufacturing. Table 4 provides the applications of AI Models in CRM and their functional tasks. In general. AI models are applied to support three main CRM types: Analytical CRM. Operational CRM, and Strategic CRM. Analytical CRM focuses on understanding customer needs and behavior by analyzing historical data and big data. Operational CRM aims to automate business processes that directly interact with customers. Meanwhile. Strategic CRM emphasizes the formulation of customer-oriented business strategies to gain a competitive edge and build longterm relationships. The classification results show that most of the AI models analyzed are implemented in the context of Analytical CRM, with the retail and e-commerce sectors as the primary adopters. One example of AI implementation in Analytical CRM within the e-commerce sector is presented in . , which developed models based on Decision Tree and Multi-Layer Neural Network (MLNN), namely the Enhanced Model for Customer Behavior and Purchase Analysis and Mouse Movement PatternBased Analysis of Customer Behavior (CBA-MMP).

AI implementation in Operational CRM was found in sectors such as advertising consulting and academic administration, where AI models are used to improve operational efficiency. For instance, study . Explored how deep learning-based AI enhanced CRM operations in an advertising consulting firm. The system utilized agent log data to replicate managerial behavior in classifying high- and lowpriority leads. Moreover, it could automatically identify the agent writing the log and predict the next word to be typed, supporting efficient documentation. Another example is shown in study. , which demonstrated that a WhatsApp-based chatbot for academic services improved service efficiency and positively impacted user satisfaction and loyalty. The application of AI models in supporting Strategic CRM can be seen in study. , which proposed an Improved LSTMbased CRM system to support automated decision-making processes in business relationship management. This system was shown to enhance inter-organizational relationship satisfaction and contribute to improved business performance in a B2B context. In some cases. AI applications have been mentioned in the context of Strategic CRM, particularly in scenarios where organizations seek to maintain competitive advantage and build long-term relationships with customers. These applications may involve decision-support systems, predictive analytics, and other AI-driven tools that contribute to strategic planning. While these examples illustrate that AI can be linked to Strategic CRM, the reviewed studies generally do not go into detail about how these systems are specifically designed or implemented in a strategic context. Instead, they mostly describe general potential benefits, such as improved decisionmaking or enhanced relationship management, without discussing the underlying processes.

What Are the Challenges in Implementing AI in CRM? The implementation of Artificial Intelligence (AI) in Customer Relationship Management (CRM) systems presents various challenges that organizations must carefully consider. One of the most widely discussed issues in the literature relates to data-related concerns. AI deployment is highly dependent on the availability of customer data, including sensitive personal Therefore, data ownership, privacy protection, and ethical use of technology are critical considerations . , . Companies must ensure that all processes of data collection and processing comply with global regulations and obtain customer consent to avoid legal penalties and reputational damage. This necessitates the application of data protection mechanisms such as encryption, anonymization, and strict access control . Another major challenge concerns the condition and quality of CRM data itself. In practice, customer data is often spread across multiple, unintegrated sources, and is typically unstructured and noisy . , . This complicates the preprocessing phase and requires complex data cleaning and transformation steps to generate valid outputs. , . , . In addition, the vast volume of data, particularly when dealing with millions of customers, can significantly hinder analysis and constrain the system's ability to generate real-time insights, especially for new customer interactions. Consequently, implementing a more sophisticated and robust CRM system is essential to leverage the capabilities of Artificial Intelligence fully. A related issue is the need for more diverse and representative data. For AI models to be effective, they must capture the complexity of real-world conditions, which requires rich, varied data. , . , . A lack of data diversity can lead to biased or suboptimal analytical outcomes. Beyond data quality and diversity, significant challenges include algorithmic bias and the lack of transparency in AI decision-making processes. Most AI models are trained on historical data, which can unintentionally replicate past biases. , . For example, systems may exhibit tendencies to treat customers differently based on age, gender, or past purchasing If left unaddressed, this can result in inappropriate recommendations or unfair decisions. To mitigate this risk, organizations must use balanced, inclusive datasets to ensure models are more representative and fair. , . Customer segmentation also presents its own set of Complex segmentation . eyond binary classificatio. is feasible only when sufficient data are available p-ISSN 2301-7988, e-ISSN 2581-0588 DOI : 10. 32736/sisfokom.

PP 467-474 for each segment . This becomes particularly problematic for small companies or minority segments with limited data . Moreover, several significant variables that could enhance customer analysis are still underutilized in the literature, limiting the representativeness of segmentation results . During implementation, organizations often struggle to adapt developed AI models to operational environments. The model's validity on real-world data is usually uncertain due to many variables that have not been empirically tested. address these challenges, organizations require more adaptive and robust model structures, along with more efficient preprocessing strategies, such as precise clustering techniques and more meaningful feature extraction methods. Additional challenges arise in cross-domain applications of AI models. Model performance often deteriorates initially and requires adjustment to new data characteristics and contextual . Furthermore, advanced tasks such as aspectbased sentiment analysis increase implementation complexity, as they demand a deep understanding of customer opinions regarding specific features of a product or service . Overall, although AI offers significant potential to enhance CRM strategies through personalization, prediction, and automation, its implementation poses complex challenges. The success of AI deployment in CRM depends greatly on an organizationAos readiness to manage data responsibly, comply with ethical and legal standards, and build systems that are fair, transparent, and reliable. In general, several broad approaches could be considered to address these challenges. Organizations may focus on improving data management practices, enhancing employee skills, and increasing investment in AI infrastructure. They might also explore partnerships with technology providers to gain access to more advanced tools and expertise. Furthermore, companies could adopt general ethical guidelines for AI use, along with basic monitoring mechanisms to ensure models remain aligned with business objectives. While these steps do not directly resolve all identified issues, they could contribute to a more supportive environment for AI-CRM adoption in the long term. IV. CONCLUSIONS This study provides an overview of AI-CRM literature from the last five years. Among the AI approaches identified, deep learning has shown substantial growth over the past four years, despite limited literature available in 2022, reflecting a shift toward more complex and advanced CRM applications that enable CRM systems to address more complicated tasks. Meanwhile, supervised learning remains the most widely adopted approach across the reviewed studies. A range of AI models has been employed across various CRM contexts, including Analytical CRM. Operational CRM, and Strategic CRM. However. Analytical CRM emerges as the most predominant focus in the literature, with tasks such as churn prediction, customer behavior analysis, and personalization being the most frequently addressed. These applications demonstrate the transformative potential of AI to enhance CRM strategies through automation, prediction, and personalization, ultimately improving customer retention and overall business performance. The review also identifies several key challenges, particularly related to data privacy, availability, quality, representativeness, algorithmic bias, and ethical considerations. These issues highlight the need for responsible data governance and the development of fair, transparent, and reliable AI Organizational readiness, including technical infrastructure and ethical compliance, is critical for successful AI-CRM integration. Future research should explore studies in a broader variety of industry sectors and include the evaluations of proposed AI Cross-domain AI models should be further investigated to enhance adaptability. More research is also needed in B2B contexts, which are currently underrepresented. Additionally, the role of AI in Strategic CRM should be examined in greater depth, as it remains a relatively underexplored area in current literature. Researchers could also test AI models across different environments to assess their REFERENCES
