Frequently asked Questions
Q: Our reporting is currently still Excel-based. Regular updates to the reports are time-consuming. Additionally, we have difficulties setting up scenario comparisons. What is the best solution for future reporting?
A: The requirements for meaningful reporting can be very individual. The goal should be to establish as centralized data structures as possible and implement automated data flows. Building on this, relevant and insightful visualizations should ideally be developed in interactive dashboards. This creates a solid foundation for future new requirements. To keep costs for new tools as low as possible, it’s worth considering existing technologies. We are happy to support you with all these challenges. After a quick check, we can provide initial recommendations for the next steps.
Q: Our employees’ knowledge is not sufficiently documented. A controller will leave us soon. Would Green Lemon Consulting be able to take over the activities on short notice and provide interim support?
A: Absolutely! We are experts in process documentation with a strong Finance & Accounting background. We are happy to help you quickly secure critical knowledge and enable you to continue control-relevant activities. In most cases, we also identify additional automation and optimization potential.
Q: What is End-User Computing?
A: End User Computing (EUC) describes applications and analyses created and used independently by employees outside the IT department—typically in Excel or similar tools. These solutions often arise from operational needs and are indispensable in many departments for analyses, planning, or control tasks. Our focus is on making these EUC solutions more robust, transparent, and compliant, as well as establishing processes and responsibilities so that end-user computing does not become a source of frustration. If EUC has led to historically grown structures, our Excel spreadsheet optimization is the right solution.
Q: We recently started using Microsoft Office 365 and want to enable Power BI for our employees. What should be considered?
A: Power BI is a cloud-based data visualization tool for building interactive dashboards and reports. When created outside IT, this counts as End-User Computing. To prevent uncontrolled growth, ensure data consistency, and guarantee data privacy and security, there are fundamental aspects to consider. Please feel free to have us assess your project as part of our remote consulting so you can fully leverage the potential of your future applications.
