Happy Customers speak up!
Ian Webb, Product Manager, Inca Software
“When Inca started to rewrite its planning software (Inca Planning) it recognised the importance to
involve good design principles with the aim of giving all users an easy to use logical interface while
satisfying the complex functional requirements.
We involved the Rave's Usability Centre of Excellence from the start of the project in conducting
stakeholder interviews and user studies. Rave‟s usability centre created the Wireframe designs and
User interface designs following user-centred design practices.
Subsequently using their skills and knowledge throughout the project we ensured that the final
product realised most the initial aspirations. Going forward, Rave‟s Usability Centre is involved with
the development of the Inca Planning GUI interface to ensure that it continues to keep its fresh look
and feel and easy to use interface while maintaining a standard design.”
Marge Hart, Sr. .Product Designer, Newforma
“Rave was able to provide insightful feedback to improve the usability of a web application used by our
customer‟s customers in the AECO industry. We found the team to be very professional during the
heuristic evaluation and final presentation of the findings. As a design professional, it was helpful to
have another set of eyes evaluate the product and find issues with an application that users and
testers had not identified.”
