AI Initiatives: identifying and promoting practical Artificial Intelligence use cases across the IT department
As Interim Head of IT for a German medium-sized industrial distributor, I am responsible for 31 IT employees and lead the digital and organizational transformation, reporting directly to executive leadership. I took over an IT department with almost no basic structures – no clear roles, processes, documentation or ticket system – and with significant technical debt that tied up most of its capacity. Introduced agile principles and ways of working in the IT organization and transformed the traditionally structured IT department into cross-functional Scrum and Kanban teams focused on transparency, collaboration, and customer value delivery.
Redesigned the entire IT organization by establishing a modern operating model, introducing new roles such as Product Owner, Scrum Master and Solution Architect and strengthening the organization through strategic hiring and targeted capability development. Recruited and onboarded Agile Coaches to accelerate the transformation and personally managed and coached Scrum Masters as well as IT department leaders to foster servant leadership, self-management and a culture of continuous improvement.
Aligned IT-internal planning across eight teams to three Flight Levels based on Klaus Leopold (strategy, coordination, team), laying the foundation for later company-wide portfolio management. Consolidated the backlog of more than 10 workstreams and prioritized it by business value and cost of delay. Introduced a ticketing system to increase transparency and enable data-driven decision-making, flow-based work management, and greater accountability at all levels.
Established and supported multiple cross-functional teams, including the Operational Core (ERP) domain with dedicated streams for Support, Feature Development and ERP Migration, as well as teams responsible for Warehouse Operations, Maintenance & Operations (M&O) including system engineering and security, Modern Workplace, Data Quality and integration initiatives. Worked closely with Agile Coaches to support team development, remove impediments, and continuously improve delivery effectiveness.
Acted as Interim Product Owner for the operation and enhancement of the existing ERP landscape while supporting the ERP migration as a Project Manager. Reorganized the project organization and had the already negotiated contract with the implementation partner realigned with a focus on approach and overall responsibility; Phase 1 (financial accounting) has been live since October 2025. Collaborated with the selected implementation partner to design and establish the project organization and target operating model for the ERP transformation, introducing agile delivery structures and ways of working. Facilitated the alignment between business, IT and the external vendor and played a key role in negotiating the contractual framework and delivery model to ensure a sustainable foundation for the transformation program.
Initiated the strategic modernization of the workplace environment through the adoption of Microsoft 365 cloud capabilities, establishing the foundation for enhanced collaboration, scalability and future digital services.
Launched AI initiatives to identify practical business use cases and promote the responsible adoption of Artificial Intelligence across the IT department. Encouraged self-management and empowered teams to take ownership of decisions, delivery and continuous improvement.

About the technology
What Data Quality Covers
Data Quality is the discipline of measuring, improving, and maintaining the fitness of data for business use. Specialists examine accuracy, completeness, consistency, timeliness, validity, and uniqueness across operational and analytical systems. The work turns scattered records into data people can trust.
Typical Use Cases
Companies bring in Data Quality expertise when critical information is duplicated, incomplete, outdated, or contradictory between systems.
- Profile customer, product, supplier, and transaction data
- Detect duplicates, missing values, and invalid formats
- Standardize names, addresses, codes, and reference data
- Monitor quality rules in reporting and data platforms
- Prepare datasets for migration, analytics, or machine learning
Ecosystem And Tools
Data Quality work connects source applications with data warehouses, lakes, integration layers, and governance programs. Professionals may use SQL, Python, spreadsheets, ETL and ELT tools, data catalogs, observability products, and master data management systems. They also work with validation frameworks and automated pipeline checks.
When To Hire Specialists
Freelance specialists are useful during system migrations, mergers, CRM cleanups, regulatory data reviews, and analytics launches. They can establish a baseline, prioritize remediation, and transfer repeatable controls to internal teams. In Germany and other markets, remote collaboration is common, while workshops may still benefit from on-site or local-language support.
What Strong Professionals Deliver
A strong professional combines investigation with practical remediation. They trace defects to their source instead of correcting symptoms in reports, document business definitions, and make quality rules testable. Clear ownership, measurable checks, and useful exception workflows matter as much as the cleanup itself.
- Data profiling with clear findings and priorities
- Reusable validation and monitoring rules
- Safe cleansing with documented transformations
- Quality dashboards that support accountable decisions
Skills To Evaluate
Look for experience with the systems that hold your most important data and with the outcomes your project requires. Relevant adjacent skills include data governance, master data management, metadata management, SQL, pipeline design, privacy controls, and business analysis. Ask candidates to explain how they protect source data, validate changes, and prove that quality has improved.
Frequently asked questions
Quick answers to the questions that come up most around Data Quality.
Data Quality is used to make information accurate, complete, consistent, valid, unique, and timely enough for a defined business purpose. Companies apply it to customer records, finance data, product catalogs, operational systems, reporting, and machine learning inputs.
Data Quality is a broader management discipline than data cleansing. Cleansing corrects or removes problematic records, while Data Quality also covers profiling, rules, monitoring, ownership, prevention, and ongoing measurement.
Data Quality work often overlaps with data governance, master data management, metadata management, SQL, ETL or ELT design, and data observability. Strong specialists also understand the business definitions behind fields and can work with system owners to resolve root causes.
Data Quality projects vary with the number of source systems, the condition of the records, and the impact of errors. A focused profiling or cleanup assignment may need a narrower skill set, while enterprise governance and monitoring require experience across architecture, processes, and stakeholder groups.
Data Quality work is often suitable for remote collaboration because profiling, rule design, documentation, and dashboard reviews happen in shared systems. On-site workshops can help when specialists must map processes with business teams or access restricted environments, and local language skills may matter for field definitions and stakeholder interviews.
Data Quality expertise is best assessed through a concrete example of profiling, root-cause analysis, remediation, and monitoring. Ask how the specialist defines acceptable quality, avoids damaging valid records, documents transformations, and demonstrates that controls continue to work.
Data Quality deliverables commonly include a profile of key datasets, a defect and impact analysis, business rules, cleansing logic, exception handling, and monitoring documentation. The specialist should also explain ownership and provide practical handover materials for ongoing control.
Data Quality requires more than validation when errors originate in upstream processes, unclear definitions, or duplicated ownership. Validation can flag a problem, but lasting improvement may require changes to source applications, master data processes, governance decisions, and pipeline design.
The average hourly rate of freelancers who have used Data Quality in their recent projects is 98 €, which corresponds to a daily rate of about 786 € based on an 8-hour working day.
Of the freelancers who have used Data Quality in their recent projects, 95% hold at least a Bachelor's degree, 68% hold at least a Master's degree, and 10% hold a doctorate.
