Digital transformation is driving companies to fundamentally rethink and modernize their business processes. In this context, AI-based workflow automation is gaining in importance, as it promises huge efficiency gains. It is estimated that up to 37% of companies use paper to manage critical business processes — a resource-intensive approach that saves valuable time (source). At the same time, 71% of companies already recognize the potential of AI agents for automation in order to relieve employees of repetitive tasks and enable them to focus on value-adding activities (source).

However, AI-based workflows go one step further: They not only enable processes to be carried out more quickly and efficiently, but also enable data-driven analyses to make complex decisions in real time and to adaptively control processes. This not only leads to an improvement in the quality of existing processes, but also opens up completely new opportunities for added value and customer service. Overall, a well-thought-out AI automation strategy is an important building block for remaining competitive and efficient in the digital age.

Traditional approaches to workflow automation are mostly rule-based. They relied on hard-programmed if-then rules and static decision tables, which was effective for predefined, repetitive tasks. However, such systems quickly reach their limits when unforeseen scenarios occur that are not reflected in the rigid rules. A lack of flexibility often leads to process interruptions or manual intervention, which results in bottlenecks and an increased incidence of errors. In addition, adapting to changing business requirements often requires time-consuming manual changes.

In contrast, AI-controlled workflows make it possible to react flexibly to changing process parameters. By using technologies such as machine learning and deep learning, these systems can learn from incoming information and adapt in real time. New data leads to dynamic decision-making without the need to explicitly formulate new rules. This adaptive character ensures that AI workflows also react to changing conditions, making processes run more smoothly and robustly. In addition, the user experience is improving, as such systems often enable more intuitive and personalized interaction. Overall, it is clear that AI-based workflows significantly exceed traditional automation in efficiency and flexibility. Machine learning (ML), natural language processing (NLP), and autonomous agents form the core technologies that enable AI-based workflows.

Machine learning is a sub-area of AI in which computers recognize patterns from existing data and make decisions without being explicitly programmed to do so. A trained ML model can, for example, make predictions or classify objects. In workflows, ML is used to learn from historical process data and, for example, to derive decision rules.

Natural language processing describes the ability of computers to understand and process human language. NLP models make it possible to automatically evaluate unstructured text inputs — such as emails, reports or chat messages. In workflow automation, NLP is used, for example, to analyze documents, classify texts, or understand user inquiries.

Autonomous agents are AI systems that can perform tasks independently and learn from their experiences without needing human instructions for every step. An autonomous agent acts in an environment, senses data, interprets it based on programmed logic or learned models, and then performs actions to achieve specific goals. It is important that such agents can continuously improve their own performance by learning from success and failure. Modern AI systems often rely on a combination of several such agents to manage complex processes.

AI-controlled systems can basically be divided into two approaches: the single-agent approach and the multi-agent approach.
In single agent system A single, central AI agent performs all tasks. This architecture is easy to implement and maintain, as all necessary functions are bundled in one module. It is particularly suitable for clearly defined, stable use cases — such as a virtual assistance bot that answers frequently asked customer questions. The disadvantage lies in limited adaptability and interactivity: With more complex, diverse requirements, an individual agent quickly reaches its performance limits. There is also no internal feedback mechanism, meaning that the entire process is jeopardized in the event of errors or failures.

The multi-agent approach On the other hand, distribute work among several specialized agents. Each agent has a specific role — such as data collection, analysis, or decision making. Close coordination and communication with each other creates a flexible, scalable and robust system. This architecture is particularly beneficial when it comes to automating complex and dynamic workflows. If an agent fails, their duties can be at least partially compensated by other agents. Research suggests that multi-agent systems offer higher processing speed and fault tolerance and are better able to deal with uncertain or incomplete data.

Single-agent systems are ideal for simple, isolated tasks, while multi-agent systems show their strengths in dynamic and complex environments through specialization and collaboration. The choice of the appropriate architecture ultimately depends on the particular use case — in some scenarios, a single intelligent agent is sufficient, in others, a cooperative team of AI agents is the optimal solution.

Companies generate large volumes of documents, from invoices to contracts to emails, with around 90% of the data being unstructured (spring). Manually processing this data is time-consuming, error-prone, and expensive.
This is where IDP comes in: An AI-supported workflow that automates the entire document process — from capture to integration into downstream systems.

IDP workflow overview

1. Document capture: Documents are imported from various sources, such as scanned paper documents, PDFs, email attachments, or photos. Using OCR technologies (optical character recognition) and preprocessing (e.g. noise reduction, image orientation), analog data is converted into digital texts so that they are ready for further analysis.
2. Document classification: The system uses layout, keywords, or sender data to identify the document type — such as an invoice, delivery note, form, or contract. Machine learning helps to correctly categorize documents so that different branches of processing are set in motion.
3. Data extraction: AI algorithms from the areas of NLP and computer vision extract relevant information. In the case of an invoice, for example, the invoicer, date, number, amount and payment term are automatically identified — even with varying layouts and free texts.
4. Validation: The extracted data is checked for plausibility and completeness. For example, a comparison with existing databases is carried out to confirm matches between customer numbers or amounts. Regulations check formats and mandatory fields, while exceptions to a human-in-the-loop approach are reviewed. In this way, the system continuously learns from corrections.
5. System integration: After validation, the data is integrated into target systems such as ERP, accounting software or databases using interfaces or RPA (Robotic Process Automation). In invoice processing, for example, a booking record is automatically created and payment transactions are initiated. Media breaks are eliminated, as the data is passed on digitally and seamlessly.

IDP demonstrates how AI-based workflows significantly increase efficiency, quality and speed in document processing. Despite existing implementation challenges, practical examples show that companies can achieve significant cost savings and process improvements by using IDP.

Despite the benefits of AI-driven workflows, there are various problems with their implementation that need to be addressed.

• data quality: The quality and integrity of input data are crucial (“garbage in, garbage out”). Incorrect, incomplete, or inconsistent data — such as illegible documents or outdated information — lead to poor results.
• Technical integration: AI workflows must be integrated into existing IT landscapes, which is particularly complex with old systems (legacy systems). Older software often does not support modern communication with AI services, which requires the use of middleware and extensive adjustments. Lack of integration leads to data silos and affects overall performance.
• Security and compliance: Since AI-based workflows often process sensitive data and make automated decisions, strict security measures and compliance with regulatory requirements (e.g. GDPR) are essential. Access restrictions, data encryption, and continuous monitoring are necessary to prevent unauthorized access and data manipulation.
• scalability: A prototype that works in a pilot project often reaches limits when used company-wide. AI workflows must keep pace with growing amounts of data, additional users, and expanded use cases without sacrificing performance. This requires a flexible, mostly cloud-based infrastructure and sophisticated orchestration methods.

The introduction of AI-driven workflows requires not only technical expertise, but also careful planning in terms of data quality, integration, security, and scalability. Only by consistently taking these challenges into account can companies make optimal use of the potential of AI while minimizing risks.

Step-by-step implementation (pilot projects)

Instead of completely automating business-critical processes right away, it's a good idea to start with small, manageable workflows. By selecting a limited use case with low risk, initial experience can be gained and the results thoroughly evaluated. Close monitoring of pilots is essential to ensure that the systems are tested in a controlled manner. Initial experiences of success create acceptance and serve as a blueprint for the subsequent rollout.

Prioritize high-quality use cases

The use of AI should initially focus on processes where automation provides the greatest benefit. Typical candidates are repetitive, time-consuming, or error-prone tasks that can be significantly improved through automation. It is important to select processes in which the data situation is stable and consistent. In this way, automation creates direct added value that justifies the investment in AI.

Integrating Security & Compliance by Design

All safety-relevant and regulatory requirements must be considered early in the planning phase. This includes defined access to sensitive data, its encryption and compliance with data protection regulations such as the GDPR. A well-thought-out concept, which also includes mechanisms for tracing decision paths (audit trail), prevents security gaps and compliance violations. The early involvement of IT security and data protection experts not only ensures technical implementation, but also builds trust among stakeholders.

AI-based workflow automation is more than just a technology trend — it is a key enabler for operating efficiently and competitively in a digitalized economy. By using AI, companies can speed up processes, reduce errors and relieve their employees of dull routine tasks. Intelligent document processing (IDP) shows the transformation potential of AI workflows — analog, slow processes are transformed into digital, scalable processes. Companies that use these opportunities and implement them with a clear vision and the right framework conditions can achieve a sustainable competitive advantage.

In the end, the aim is not to see AI in isolation, but as an integral part of a comprehensive digital transformation. If this is successful, AI-based workflow automation paves the way to permanently higher productivity, more freedom to innovate and better added value.
