A análise da operação agrícola como base para a definição de requisitos funcionais no processo de desenvolvimento de máquinas agrícolas.

Abstract

The agricultural machinery development process encompasses a set of phases which start from the recognition of a market opportunity up to the launch of an agricultural machine (AM) and its aftersales validation within the intended market. However the execution of a formal development process is not a guarantee for the market success of the AM, if the motivating need for such undertaking is not to be translated into adequate functional requirements for the operational context of its potential users. The undertaking of this work involved, in the first phase, the survey of references wherein the agricultural operation is characterized. They were found with organizations of descriptive approaches upon machinery by agricultural task, and an example of systematic method of characterization for the same. Such survey created conditions for the execution of a case study on that characterization in an academic work on the definition of functional requirements for a small lawn/garden tractor. The attained results allow concluding that the systematic consideration of the agricultural task makes it easier to synthesize functional requirements for good operation performance of AM in the crop field.
