The 'Completed Tasks Overview' on the RD Station CRM Dashboard, developed by Kondado, is a dynamic counter that adjusts according to the selected filters on the panel. This feature provides a quick and adaptable analysis of tasks that have been completed in different contexts, such as by period, responsible party, sales funnel, among others. This allows for an immediate understanding of the progress made and the productivity of the team over time, facilitating the identification of patterns and trends to optimize future sales strategies.
