Please note, visualization is one component of BI and not complete BI. It is a common mistake to compare the cost of visualization tool alone while selecting BI tool/strategy. Here are some of the critical components of BI that needs to come together seamlessly for long term success:
Connection: This is one of the most challenging components of BI. Most BI tools struggle to connect to all/majority of data sources that may be needed for building KPIs. Please ensure that the tool you select allows you to automatically connect to all key data sources. Typical data sources are ERP, on-prem applications, excel, csv, google sheet, cloud applications like salesforce, social media applications for marketing data i.e. Facebook, Google Analytics, Twitter, Instagram etc.
Storage: Once connected to the data sources, the needs to be stored at one common place where you can integrate them and build business logic. i.e. SQL Server, Azure Synapse, Snowflake etc. Please ensure that the data warehouse you choose can process the volume of data your business would use at an acceptable speed. While making decision for the organization, think of long-term data volume processing need.
ETL: Data coming from various systems in its raw form can hardly answer any question, therefore joining multiple datasets, adding business logic is very common without which data visualization can not happen. ETL is perhaps the heard of BI, without ETL, you can’t imagine BI success. The speed and ease of data transformation are key considerations.
Visualization: This is where you build KPIs to answer business questions. Most visualization tools cover basics of visualization, some may be more visualization as compared to others. If you have very specific use case and have any special need, you may want to ensure that is covered during the evaluation phase. You must ensure that the Performance of the dashboard with large volume is acceptable else it will be a big challenge for user adoption.
Collaboration: Not all BI tool offers this feature but, this feature can take your BI experience to a completely different level. This feature allows you to collaborate/converse on the KPIs in real-time with all the stakeholders without having to rely on offline email communication to initiate action.
Notification Alert: This is another feature that will significantly enhance the power of information in the organization. This feature allows you to set an alert on the KPIs so you get notified when the exception occurred. This facilitates management by exception and is extremely handy to monitor business performance in real-time.
