SIAGRO is a project composed by several systems that serve as registration and source of information for the Brazilian National Supply Company’s (Conab) experts. It has a fundamental role for the Brazilian government, because subsidizes analysis and decisions based in prices and agricultural and livestock production.
The purpose of the Value of the Production module (VBPA) is to calculate the volume of the agricultural and livestock production. I designed this module interfaces according to the specifications documented and with the existing interaction model. I developed the prototypes, that were approved by the users.
