Why Power BI Requires Ongoing Internal Expertise
Many businesses adopt Microsoft Power BI to improve their reporting and move away from manual spreadsheet processes. The platform offers powerful tools for building dashboards and visualising data, making it an attractive option for organisations looking to modernise their reporting.
However, one of the most common challenges SMEs face is the level of ongoing expertise required to maintain a Power BI reporting environment.
While creating dashboards is an important first step, it is only part of the overall process. In order for reports to remain accurate and useful, the underlying data structures, models and calculations must be maintained over time.
This requires a combination of technical and business knowledge.
Data from systems such as accounting software, ERP platforms and other applications must be extracted, transformed and structured correctly. Relationships between data tables need to be defined, and calculations must reflect how the business measures performance.
As reporting requirements evolve, these models often need to be updated.
New products, changes in pricing, additional reporting dimensions or adjustments to how performance is measured can all require modifications to the reporting environment.
Making these changes is not always straightforward. Power BI relies on data models, transformations and calculations that must be carefully managed to ensure that reports remain accurate.
For businesses without in-house BI expertise, this can become a challenge.
Responsibility for reporting may fall to finance or operational staff who understand the business but do not have the technical skills required to manage the reporting system effectively.
Alternatively, businesses may rely on external developers or consultants to make updates. While this can work, it introduces ongoing costs and dependency on external support.
One finance director described how their organisation implemented dashboards but found that maintaining them required more time and expertise than expected. Changes that seemed simple often required technical input, and over time the reporting environment became something that needed continuous attention.
Another issue is continuity.
Power BI solutions are often built by a specific individual who understands how the data has been structured and how the reports function. If that person is no longer available, it can be difficult for others to take ownership of the system.
New developers may need time to understand the existing models before making changes, which can increase both cost and delay.
As a result, what begins as a reporting improvement project can evolve into an ongoing responsibility that requires internal coordination and technical expertise.
For many SMEs, the challenge is not creating reports — it is maintaining them.
Illuminis provides a different approach through the Octelas business reporting platform.
Rather than requiring businesses to manage their own reporting environment, illuminis acts as a long-term data partner. The reporting system is designed, implemented and maintained as part of an ongoing service.
This begins with understanding how the business currently reports its data. Existing spreadsheets, calculations and reporting logic are reviewed and recreated within a structured reporting environment.
Once implemented, reporting is continuously supported and developed. When requirements change, updates are handled as part of the service, without the need for internal technical expertise.
This removes the dependency on individuals within the business and ensures that reporting remains reliable over time.
One managing director described the benefit as having a reporting system that did not require ongoing internal management. Instead of needing to understand how dashboards were built or maintained, the team could focus on using the data to run the business.
For SMEs, having access to reliable reporting without the need for in-house BI expertise can make a significant difference.
While Power BI can be a powerful tool, many organisations find that a fully managed reporting solution provides a more practical and sustainable approach.
By removing the need for ongoing technical involvement, businesses can save time, reduce complexity and focus on making better decisions using their data.
