Interactive development of web-based applications containing decision-makers

Web applications that contain personalized offers involve an interaction between client and supplier. The supplier faces the dculty of building a wide range of offers, which ultimately come to be personalized, and the customer is confronted with defining its requirements. An example might be a web application that offers houses with modular structure. The application can offer several types of homes, in which case it will only satisfy a small number of customers or can provide solutions for each client. Providing customized solutions to each customer can be accomplished through direct communication with the design expert, but this involves high costs or a small expert system that assists the customer in building the offer. This last solution implies a step-by-step development so that the expert system meets customer requirements in identifying supply data. A construction of customer demand details can become difficult and the client should learn to use the specialized software for house design, which would reduce the number of clients. The paper aims to present an approach that minimizes the costs of developing and operating such a software application.
