Uma linha de produto de software para micro e pequenas empresas

Abstract

When building an automobile, a car product line may use the same body and engine to build a specific car model. Different parts allow the creation of different cars. This same parts reuse procedure can also be used in software through a Software Product Line (SPL). In an SPL a common code contains the components considered base that are used for the creation of all products in the line. Variations in components allow the creation of different products. An SPL is always implemented in a given domain. The domain chosen for the SPL of this work is the trade of micro and small enterprises. The features implemented within the SPL were: dashboard, sales control, item, employee, customer, and notify customer. For the SPL construction, the following technologies were used: Node.js, React, Next.js and TypeScript. To validate the proposed SPL, a pilot experiment was initially carried out with four participants who gave suggestions and criticisms. The final experiment to validate the SPL was carried out with eleven participants who gave their opinions on the proposed SPL. It was used the Technology Acceptance Model (TAM) to collect data about the perceived ease of use, perceived usefulness and intention of use of the proposed SPL. The results showed that the SPL was considered easy to use (mean 4.37 out of 5.00), was considered useful (4.25 out of 5.00) and that the participants intend to use SPL (4.22 out of 5.00) in the future. It is expected that the proposed SPL may benefit the trade sector for micro and small companies, because this SPL will assist managers in decision making, and better communication with its customers. Moreover, there may be a possible productivity gain of its employees
