Is there any BI solution that is easy but have a complete modul?

Usability is defined in ISO 9241-11 standard fitness-for-use in specific context. Therefore you need to identify contexts that you interested in measuring the usability. Context is defined in the ISO: User, Tool, Task, Environment.

According to Forrester Research, Business Intelligence is often defined in two ways - broad and narrow. The broad category includes topics like DW, MDM, Predictive analytics, Data Quality. The narrow definition means BI-suites as traditional reporting platforms. I assume you are focusing on narrow BI-reporting platforms.

Considering your topic and interest, you should combine ISO and BI issues.

Users: BI-admin, BI-developer, BI-Power user, BI-consumer. Each technology provider has a slightly varied version of these user groups. All user groups have one or more tools that are developed for their tasks.

Tools: Admin Module, web-tools, client-tools, graphical client-tools, mobile tools etc. The same functionality can be provided with different technological tools at the same time. For example SAP BO has had their ad hoc-reporting tool (WebI) as a rich client and web-version with nearly identical functionality. On the other hand, KPIs might have been constructed with WebI or XCelsius dashboards, although they are completely different in their usability and technical flexibility. There can be several tools for one activity but also one activity can be done with many alternative tools. Also in a single BI platform.

Tasks: Administrating, data gathering (building semantic layers, ad hoc-ETL), data manipulation (build reports, explore data sets, create KPIs, statistics), data publishing (static reports, drill-in reports, KPIs, graphics). There is huge difference how easily each task can be done and how significant limitations each tool has. One tool might be really easy to start with but soon you end up in significant restrictions. You simply cannot do something, although BI suite seems to have a tool for it. Or doing something requires massive efforts and becomes very risky network of human errors and technological workarounds.

Environment: Desktop in office, mobile out-of-office, offline in wilderness, cloud-based multi-context use. Again, the same task can be done in various environments with different tools. Mobile tablet can be used to build a new report or you can analyze millions of rows data completely offline in wilderness.

Each BI suite varies a lot in their usability and completeness even in this quite general level.

In conclusion.

You can not compare SAP Business One or OBIEE unless you define and decide more general use cases and frameworks. What you are actually evaluating. You need generalized categories that can be used limit your evaluation:

a) user types and their needs,

b) tool types and their required features

c) task types and their aims

d) environments.

Then you need to develop tests for each category. Then you need to perform the test to measure whether tools pass them or how they pass. In fact, a lot of tasks can be done with all major BI suites - it just depends how these are done and by which tool. And what kind of restrictions you might end up having problems with.

For example, SAP BO or Microstrategy are really easy to use on top of semantic layer. However, building the layer requires significant work and understanding. To accomplish something you might need to redefine semantic layer or even data warehouse. Also each BI suite has probably several tools for each task. They vary according to easy-of-startup but also flexibility-in-the-end.

I would say that there is no such thing as and you will not find "the best" or "the most complete" BI Suite. It depends on what you are trying to do and what you want to include in your comparison. Each BI suite has own advantages and specific limitations.

BI Suites are evaluated yearly by Gartners Magic Quadrants for Business Intelligence Platforms and Forrester Research (Wave Reports?) about Enterprise Business Intelligence Platforms. Both reports have a huge lists of BI Suites and even larger llists of technologies that they have been following, but did not perform full-scale evaluation.
