Description of Activities

The BP EDO research group advances digital transformation by extending traditional ERP strategies with customer-oriented change management and a strong emphasis on sustainability and innovation. Core activities combine generative models, large language models (LLMs), advanced analytics, and natural language understanding to resolve complex ERP challenges. Enterprise architecture best practices such as datatype driven data management and service-oriented architectures (SOA) ensure interoperability, while AI generated proxy services and in memory databases deliver maintainable user interfaces and optimized performance.

Web enablement and SOA design operate across multiple layers. At the composite layer, dynamic development techniques create new applications. At the workflow layer, process engine orchestration (BPM) and edge computing provide real time data processing. These layers support AI-driven orchestration and adaptive service execution that align with intelligent enterprise principles spanning cloud strategy, DevOps, and data privacy and security, while enabling AI and BI functions across the enterprise.

The group analyzes natural language understanding (NLU) and rapidly evolving GUI technologies including generative AI and LLM powered interfaces, tracking their adoption from mainframe to client server eras and into modern contexts. Barriers to adoption are investigated, particularly where cutting-edge interfaces introduced first in educational settings can accelerate digital transformation and sustainability in business. Cognitive Information Systems and human computer interaction research underpin adaptive decision support environments that cultivate transparency, personalization, and trust through dynamic infocommunication loops. Expertise in process management, software optimization, best practices, and data visualization fuels novel BI and AI driven visual techniques that enhance insight and usability.

Dynamic development spans AI assisted code generation, data mining, and rigorous testing across UI, backend, database, and secure communications. Research also integrates edge computing for real-time performance gains. Advanced analytics and predictive modeling forecast business environment changes, enabling proactive adjustments to software and architecture. Intelligent version control and DevOps practices optimize performance indicators, ensuring alignment with cloud strategy, data privacy, security, and sustainability targets.

Supporting the group's broader digital transformation goals, this data-driven study on SAP implementation in SMEs examines how small and medium-sized enterprises customize standard SAP ERP systems. Analysis of multiple projects reveals common areas requiring adaptation, such as financial reporting, inventory workflows, and user role management. Identifying these recurring needs helps SMEs anticipate challenges, avoid costly late-stage changes, and streamline implementation. The insights lead to practical guidelines that improve the predictability, efficiency, and alignment of ERP systems with SME business needs.
