Abstract

We live in an era in which the race after time is one of the main challenges imposed on organizations and society in general, which is why some compare time to money and, in fact, the dynamics of the market and business in They generally require activities to be carried out in record time because the less time it takes to carry out tasks, the greater the possibility of gaining considerable space in the market. Customers are interested in having the results (products) as soon as possible and they will choose whoever promises (and of course fulfills) makes them available in a relatively short period of time. This reality is shared by almost all types of organizations because in all of them there is the one we call the customer (the beneficiary) who is not interested in waiting so long for a result. In this context, several organizations/companies feel pressured to adopt new work mechanisms in order to satisfy the increasingly demanding customer in terms of product quality and the time he has to wait for them. These mechanisms are based on the use of techniques, tools, and methodologies that make organizational activities more flexible. Among the organizations most affected by this new business dynamic are those dedicated to the development of computerized applications (Leite, 2007)^ The growing demand for automated information systems causes application developers to find themselves overwhelmed by application development projects which have very strict execution time constraints, that is, project delivery times are very short. that they have sought to use sufficiently flexible methodologies to respond to this and other market demands. In order to respond to market dynamics and satisfy requirements such as consistency (of applications), flexibility and low cost (in terms of development efforts, development time, etc.), those dedicated to application development have been coming to employ application development techniques, among which we can highlight: Functional programming, Logic programming, Structured programming, modular programming, event-oriented programming, among other application design methods. One of the techniques that proved to be powerful for achieving the attributes listed above is object-oriented programming, which until today is an almost inevitable option for the development of low-cost, flexible and easy-to-maintain applications (Larman, 1998).
