Laura Kerrigan provides a summary of her approach to segmented marketing. She begins by gathering existing marketing data from local ACDC markets through discussions with local marketing and sales teams. This information is compiled into databases to understand audiences, capabilities, and needs. Customer personas are then established based on segmentation of end users. Finally, the consolidated insights are presented to global teams to identify any gaps between local and global strategies. The goal is to develop local market toolkits that match the segmented knowledge and drive sales through tailored marketing materials.
