TAX-i application [Logica, HWH]

2009 – 2010 • Logica
The TAX-i project consists of 2 applications; ODB which leverages municipal data across silos, and UBS that calculates water levies based on this data. It is being co-developed by Logica and a couple of Water Boards. Representatives of the Water boards and users of the system are part of the acceptance procedure.

I was responsible for the Interaction design of ODB (Java) which would often be used in unison with UBS that had already been developed in Oracle. The challenge was to adopt enough of the interaction patterns / behavior of the existing application for consistency of use while still trying to improve the user experience of the new application.

Responsibilities:

• Leading workshops to collect user requirements,
• analysis of the interaction patterns used in UBS,
• making interactive prototypes,
• writing the interaction design document (describing a.o. usability guidelines, user mental models, navigation, interaction patterns and errors, alerts and confirmation).
