The breadth of features, compared to the simplicity of implementation and use. The product doesn’t try to do everything, for everybody – but it has a broad range of capability. As an implementer, the ease of installation, plus how quickly you can bring a customer up to speed is important.
I have been involved with the implementation of many BI products; many products are expensive, require complex and difficult implementations, and once installed it is only the start of a lengthy consulting engagement to get the installation to where the customer wants it to be. Yellowfin is the antithesis of this; it installs easily, the configuration is done quickly, and the user can come up to speed quickly (especially if they have used other BI products). As an implementer, this changes how we operate, because we can focus on providing the customer what they want, not just on technical wizardry to get the product operational.
