The ability to customize it. This involves a bit of programming however and that can be an issue. For data visualization, it involves the end-user with self-service BI. It's ETL functions are powerful as well, but this is a bit of an old fashioned approach.
Improvements to My Organization
Annual Information from public sector following transparency laws are now publicized in an automated way. Previously, this task used to involve a lot of scripting development and data warehouse routines, such as ETL. Now all this is done using QlikView and raw data.
Room for Improvement
Actually, Qlik, has decided to move forward with a brand new product, Qlik Sense, so it seems that QlikView can be deprecated as it follows an older approach that pre-dates data visualization in data warehouse and BI.
Use of Solution
I've used it for the last two years.
The tool involves too much programming when compared to other tools. It has a development/delivery circle as any internal system development for test/production environment does.
There have been no stability issues and a restart can be automated on a virtual machine.
The product eats all memory you give according to the number of accesses it gets, as the navigation is buffered for future queries. Ideally, the datasets must be summarized to the granularity that the public expects.
Customer Service and Technical Support
It was done with technical support, but I wouldn't classify it as complex.
We used a vendor team who were 9/10.
This is not easy to measure, but senior management and the public are satisfied.
Pricing, Setup Cost and Licensing
It's aligned to the market, but document viewing and sharing constraints are a bit confused and intimidate. They have changed their approach for Qlik Sense.
Other Solutions Considered
All proof of concepts used trials and it's not easy to buy a specific product for the government, so the management decision was to apply to an on going acquisition process where the product was already chosen. Two other options were Tableau and Infogram.
Their competitors seem to be more up to date with features and technology. Check whether Qlik Sense is better for you, otherwise you may acquire a legacy tool.
