 What are the biggest disadvantages or drawbacks of using Power BI ?

While Power BI is a powerful tool for data analysis and visualization, it does have some disadvantages and limitations to consider:

Cost:

• Free version has limitations: The free version offers limited features and data storage compared to paid versions. Businesses with complex data needs or large datasets might require paid plans, which can be expensive.

• Additional costs for data connectors: Certain data connectors, especially for enterprise applications, require separate subscriptions or licenses, adding to the overall cost.

Performance and Scalability:

• Can be slow with large datasets: Complex models and massive datasets can lead to performance issues, especially in the free version. Users might experience lagging when interacting with visuals or refreshing data.

• Steeper learning curve for complex models: Building and managing intricate models with numerous calculations and relationships can be challenging for beginners, requiring investment in learning and training.

Data Security and Governance:

• Security concerns with DirectQuery and Live Connections: While convenient, these connection modes might raise security concerns for sensitive data as it resides on external sources. Careful configuration and access control are necessary.

• Limited user authentication options in the free version: The free version offers less granular control over user permissions and access levels compared to paid versions, potentially impacting data security and governance.

User Interface and Usability:

• Can be cluttered and overwhelming for beginners: The Power BI interface, with its numerous icons and options, can be intimidating for new users. A learning curve is involved before becoming comfortable navigating and utilizing its full potential.

• Mobile limitations: While Power BI mobile apps offer on-the-go access to reports and dashboards, functionality is limited compared to the desktop version, hindering complex analysis or data manipulation on mobile devices.

Additional Drawbacks:

• Limited offline functionality: The free version restricts offline access to reports and dashboards, requiring consistent internet connectivity for analysis.

• Dependence on Microsoft ecosystem: Power BI integrates seamlessly with other Microsoft tools and services, but might not be ideal for users heavily invested in non-Microsoft environments.

Overall, Power BI remains a powerful tool for data analysis and visualization. However, it's essential to understand its potential drawbacks and ensure it aligns with your specific needs and resources before adopting it. Weighing the benefits against the limitations, coupled with exploring alternative solutions, will help you make an informed decision for your data analysis requirements.
