The term "I-shaped" refers to a type of skill set or professional development characterized by deep expertise in a specific area, represented by the vertical line of the "I." Individuals with I-shaped skills possess a strong foundation in one discipline, allowing them to excel in that field. In contrast to "T-shaped" professionals, who have both depth and breadth of knowledge, I-shaped individuals focus primarily on mastering their core area. This specialization can lead to high levels of proficiency and innovation within their domain, making them valuable assets in fields such as engineering, medicine, or research.
