Define a simple and uniform use

But the Baker struggles to avoid user specialization by Functional Domain. Once trained in a job, the actors don't want to change as the gap between positions seems too big to them.

The specialization of actors in their jobs hampers internal mobility.

The ergonomics of the workstation can be optimized and standardized from one station to another, in order to facilitate its acceptance and therefore the versatility of the actors. For the IT Solutions, we can harmonize the formatting, navigation, authentication, security... to facilitate and harmonize the "user experience"...

Each new Solution is built with the same user interface. We reuse the same ergonomic components, the same presentation of examples, the same navigation, Workflow Engine, the same security mechanisms. From here on in, the employees accept to change activity..

  1. The Usability Value becomes essential

    The user admires what is complex, but likes what he/she understands: it is what guides his/her purchase motivations. Ease of use is one of the keys to success.

    We remember the survey that showed that 50% of video-recorder users only knew how to play the cassettes and did not know how to record on them! The many buttons and functions provided by the manufacturers to justify the more expensive prices made no sense.
    On the other hand, the design and ease of use of a device like the iPhone was the main reason for its success. This is also an opportunity to show that being rich in functionality does not necessarily mean having a complex user interface.

    The automobile manufacturers are thinking about new interfaces that will replace the many buttons that can be found on the dashboard. Several possibilities are being examined: go down a menu to choose a specific item (radio volume, temperature, indicators...) with a simple hand movement in front of a screen, thanks to a gesture recognition system, or even by using cameras to detect the driver's eye movements. Advantage: being less distracted enables us to concentrate on the driving.
  2. Uniform usability facilitates acceptance

    Uniform Usability has profound consequences on the acceptance of new Solutions by the users.
    Learning one way of Using something takes time: some say that you have to forget a functionality 7 times in order to assimilate it. If new Solutions are provided that respect the same usability as previous Solutions, then the Actors are on known ground: they will like the new Solution because they know how to discover and navigate their way through it; the difficulty is transformed into a pleasure. The Enterprise gains a more flexible organization as it becomes far simpler to change where we assign the Actors.

  3. How do we obtain uniform usability?

    There are several approaches:
    • Use Solutions that are broad in scope: the same development team, whether it be in-house or external (software package or Cloud) provides different functionalities with the same user interface. It is therefore in our interests to seek Solutions offering the maximum of functionalities. If the development is in-house, we must make sure that the development team has established its standards properly (that can be based on well-established standards) and that they ensure they are respected within the team; the best method is to carry out ergonomic reviews during the development. 
    • Provide Components to Solution builders who generate standardized user interfaces, whether for the "look and feel" or the navigation.
    • Choose Solutions where the "user interface" is isolated so that it can be personalized.
