What I like best about Qlik Sense is the way its associative engine handles complex, multi-table telecom and activation datasets without breaking the model. For our modem activation dashboards, it’s extremely helpful to link VIN-level data, activation events, modem health signals, and backend system logs in a single Qlik data model. The ability to script transformations in the load editor, perform incremental loads, and manage large QVD layers makes the pipeline stable even with high-volume activation data.
The visual layer is equally strong-things like set analysis, custom expressions, and responsive KPIs let me build very granular views (e.g., activation rate by model year, carrier, region, modem type, or failure codes). The SaaS version performs especially well for heavy dashboards, while the on-prem version gives more control over data gateways and refresh schedules. Overall, Qlik Sense allows me to handle complex activation workflows and root-cause analysis in a way that’s both scalable and technically flexible. Review collected by and hosted on G2.com.
The biggest downside of Qlik Sense is that some of the advanced features still require a fair amount of scripting. Things like complex data transformations, incremental loads, or handling edge-case modem activation logic often need Qlik load script workarounds instead of native UI-based solutions. Managing section access and data security rules can also get tricky, especially in environments with multiple data sources and frequent schema changes. On the visualisation side, the customisation options are somewhat limited unless you rely on extensions, which aren’t always stable or supported across SaaS and on-prem.
Performance can also be inconsistent-large activation datasets load well with QVDs, but live connections or heavy front-end calculations can slow down both SaaS and on-prem servers. Overall, Qlik Sense is powerful, but the complexity in scripting, limited UI customization, and dependency on strong data modeling skills are the main pain points.
