Overall Satisfaction with Qlik Sense
All employees throughout our organization use Qlik Sense as the primary tool to analyze and improve the performance of our online advertising products and to follow company KPIs. It has certainly changed the way we can react to things and made the company more data-driven.
- Qlik's associative data engine (based on a proprietary in-memory database) makes the slicing and dicing of data very easy.
- Self-service aspect: it's easy for the end-users to create their own variations of existing sheets to better suit their needs.
- Easy to use: end-users learn how to use it in a short time.
- Inflexible licensing model. For example, if you purchase per-user enterprise licenses for your users (which are expensive), you cannot decrease the amount of them later.
- Doesn't work that well if data sets cannot fit into memory.
- Query language (especially 'set analysis' functions) is quite complex and unlike most programming languages.
- Some calculations are difficult to implement with Qlik.
- Many third party visualization (available in "Branch") are of low quality.
- Makes organization more data-driven.
- Promotes self-service and general interest in data.
- Frees resources by removing need for generating ad-hoc reports manually.
Qlik Sense suits very well for use cases where the associative data model shines, i.e. finding reasons through quickly slicing and dicing through the data. It's also very easy to use from the end-user perspective and that's why many business users love it. For complex ad-hoc analysis and more flexibility, data scientists may want to use other tools to complement it.
