Uma investigação da usabilidade de uma plataforma web na escolha de cultivares da embrapa soja

Abstract

Embrapa Soja is one of the 43 research units of the Brazilian Agricultural Research Corporation (EMBRAPA) and is a global reference in developing technologies for soybean cultivation in tropical regions. The Communication Core (NCO) of Embrapa Soja is responsible for disseminating technologies, techniques, and guidance developed by Embrapa Soja researchers to soybean farmers and rural technicians. This dissertation presents the development and usability evaluation of Embrapa Soja’s Web Platform of Cultivars, aiming to assist soybean farmers in selecting the best cultivars for their regions. The platform was conceived as a solution to the challenge faced by Embrapa Soja in providing up-to-date and accessible information about soybean cultivars. The importance of making the correct choice of cultivars is fundamental for the success of soybean production, as improper selection can lead to significant losses in productivity and profitability, as well as affect the environment. In this regard, Embrapa Soja sought to develop a platform that would offer reliable and up-to-date information about their soybean cultivars. After implementation, the platform was evaluated in three dimensions: usage, user satisfaction, and heat and area maps analysis. Participants from different regions of Brazil, recommended by Embrapa Soja’s NCO, were invited to use the platform on their own devices. Usability evaluation was conducted through SUS and UEQ-s questionnaires. The results indicated that overall, the platform’s usability was considered positive. However, specific points, such as difficulties in use, were highlighted, suggesting the need for improvements in interface and navigation. User satisfaction survey, conducted through a structured questionnaire, revealed that the majority of participants are content with the Web Platform, with a significant percentage of responses indicating a high level of satisfaction. The CSAT (Customer Satisfaction) was calculated at approximately 76.54%, confirming the positive assessment of the platform. The analysis of area heat maps, performed through the Clarity plugin, provided valuable insights into user behavior on the platform. Area maps revealed that the cultivar search functionality is extensively utilized by users, representing over half of the clicks on the main page. These results underscore the relevance of this feature to users and emphasize the importance of suitable usability.
