What are Factors to consider before buying a Data Visualization Tool?

Factors to consider before buying a Data Visualization Tool

Data Environment – With big data and its volume, we all know we don’t get data feeds just from one system. So the tool should be adaptive enough to support feed intake from multiple systems

Real Time IndicatorsGartner report recently concluded that most of the CFO’s rely on real-time indicators to make a decision. Hence, the tool you choose should support real-time data feed and able to process the infographics accordingly.

Visual Displays – The product under scrutiny might offer a lot of options for visual display. But make sure take a test run on the infographics you wish to choose for your firm and are they able to provide the key indicators you need for your business.

Ability to integrate with your current system – You wouldn’t be willing to buy something that cannot be integrated with your existing system. So do run a smoke test to check the feasibility.

Analytical Features – Most of the data visualization tools do come with some intelligence to help with data analysis [that most of the seller will mention explicitly], but they are not that powerful to help you with decision making at times. So do gather the information on how powerful is the product in analyzing, may be in terms of data depth or terms of percentage.
