Our software architects provide an interface between the client and our developers, creating a high level requirements definition based on the user's needs, and taking into account time, cost and other constraints. The architect prototypes the proposed system with the client and the developers using ViaData's Catalyst™ prototyping and development platform, together with data modelling, to ensure that what is required in terms of functionality and interoperability is architecturally and operationally feasible. This process also allows the client to get an initial feel for the system, and client requested enhancements can be added dynamically.
