Overall Satisfaction with QlikView
QlikView is being used as our Enterprise Analytics Solution to create dashboards containing HR, Payroll, Finance, Training, and other data. It has helped to reduce ad hoc reports and increase communication and awareness. It has been utilized for general info and to help target specific problems.
My use of Cognos was as an embedded BI tool inside of a cloud HCM. At the time, you could not marry up data from other external sources with that version. QlikView makes it easy to connect data from multiple sources. As a BI tool I do prefer the Cognos set up, but that's more of personal preference. Security was also different due to the way it was deployed, but QlikView can do anything Cognos did and sometimes better with data visualizations.
As an organization we have been able to deploy many dashboards and have a civilian developer model, where many individuals can contribute to building dashboards with some oversite of a centralized BI team.
