Izenda Business Intelligence

Izenda allows seamless white label integration for non-technical users but also allows technical users to customize all areas to provide a powerful solution that matches their core solution. It pushes the reporting burden away from IT and into the hands of the user and allows for complex reporting in a simple to use UI experience.

The documentation whilst getting better still needs to be kept more up to date

I really like their flexible architecture. They have many integration and stand alone modes that fits all scenarios. The technology stack aligns quite well with ours - so that was a plus. The visualizations and ad hoc reporting capabilities are great. The simple licensing model is a must, and very good customer support.

The documentation on integration for both series 6 and 7 is a bit lacking - although I have seen a great push on getting it updated, its had to get any fine details. Due to this it has taken a long time for us to embed the solution properly.
Although series 7 has many advantages, it is also lacking in certain areas compared to series 6. Having no export of the reports makes it hard to mange tractability with source control. 7 series is still quite immature with a lot of bugs. Performance is always a concern.

Izenda fit well in the "good enough" domain. It answers most business analytics and reporting needs without having to hire an army of developers and/or pay a tremendous amount. The embedded analytics model lets you develop customized solutions that can be given to end-users. but it is also powerful enough that it can be used for more advanced purpose.
I personally have been using Izenda for less than 6 month and the learning curve is somewhere between Tableau and Qlikview to get to the expert level.
Most end-users will learn how to navigate reports and dashboards designed for them in a couple of hours as most features are quite intuitive and fit most needs.

The onus is on the developer of Izenda's applications to design applications that are easy to use. Most complains are related to people trying to use out of the box features that need a little bit of in-depth knowledge - mainly SQL and database related - in order to use the whole potential of Izenda.
Charts start to look and feel a bit outdated, but each new release brings updates that address the problem.
