power users. These concerns may overlap partially with the blinking twelve problem, in which a complex user interface causes users to avoid certain features. It may be extremely difficult to both appeal to new users, who want user interfaces to be intuitive, and experts, who want power and flexibility. However, there are solutions for these problems, such as: Product variations Operation modes More advanced features, options and settings logically separated in submenus. Users may also erroneously label themselves as power users when they are less than fully competent, further complicating the requirements of designing software which caters to the desires and needs of those users. Simplicity vs. efficiency A simple intuitive interface often increases the technical complexity of a program and impedes its efficient use, while a well-designed but complex-seeming interface may increase efficiency by making many advanced features quickly accessible to experts. For example, a program with many advanced keyboard shortcuts may seem to be needlessly complex, but experienced power users may find it easier and quicker to avoid long sequences of mouse clicks to navigate menus and popups. Such menus and popups may exist to intuitively guide new users along a desired course of action, but they are often overly-simplistic by design so that novices might easily grasp the required steps. Providing both interfaces simultaneously is an option but requires greatly extended development time, so trade-offs are often made. Officialized roles SAP and Oracle SAP and Oracle are enterprise systems that require a complex set of training to gain professional certification. Because of this, and also to encourage engagement with the systems, many companies have created a "Super User Model" (also called Power User, Champion) to take regular users and raise them to a level of leadership within the system. Doing this accomplishes three objectives: More engaged use of the system as there is a personal face assigned to champion the system and make acceptance of the technology less challenging. A significant time and cost reduction as companies are not seeking or hiring new or temporary resources for the purposes of developing and/or delivering documentation, training, and support. ROI or proof of concept of the SAP investment should be more easily achieved as users are directly involved, thereby using the system invested in, which benefits the company overall. Extensive research has been done with the Super User Model in SAP, specifically in regard to the role they take
