In-Depth Information
In this example, access to a service group is considered as being a change in the
active business process and will be identified as such in the history of category
changes. Given the distribution of confidence levels, the category change could
require a certain amount of time to really be taken into account.
During the Viatic.Mobilité project, due to a lack of time it was only possible to
conduct a limited number of experiments with test users. This did not enable us to
provide a definitive conclusion regarding our global approach, but we did identify
three initial avenues for improvement:
- the semantic characterization of the category of travel time experience of users
is not easy to define for sure, as each participant within the work groups can make
his own interpretation of the needs analysis results;
- the definition of the confidence levels for each category is currently more
experimental than scientific, and it has not yet been possible for us to define a
collection of rules to determine them in a confident manner;
- the validation of the approach by carrying out surveys in the field is not easy as
each surveyor may have his own perception of different categories; certain situations
perhaps leading to different conclusions depending on the surveyors.
That being said, a certain number of results have been able to be determined:
- the use of confidence levels enables us to have results for the applications that
are closer to the real behaviors and needs observed by the surveyors in the field;
- the number of incorrect changes in categories of travel time experience within
an application is limited.
In fact, the main problem identified during the field surveys was the difficulty in
having reliable information about the category of the user when he is not using the
application. This can lead to poor category choices and/or a certain adaptation time
to determine the real category of the user.

An example of business process personalization: the organization of a trip
To illustrate the case of the adaptation of a business process to the category of
travel time experience, we will present the example of a business process, the aim of
which is to enable the display of information associated with the next departure of
the user. The analysis of needs has given rise to the identification of two different
adaptations of the business process. The first, linked to the
Beaver
category, enables
the display of information concerning the trip to be linked with the information
contained in the work schedule of the user in order to give him information
regarding the reason for the trip and about the next rendezvous. The second,
