Dashboarding, as described by the author, is a method of transforming scattered data into actionable insights through visualizations such as pie charts and bar graphs, which can help companies improve their Software Development Life Cycle (SDLC). By capturing and analyzing data from various sources like source code management systems, project tracking systems, and CI systems, organizations can monitor metrics such as commits per pull request, time to merge, and lines of code to identify bottlenecks and inefficiencies. This process allows for a deeper understanding of internal team performance, coding quality, and deployment frequency, ultimately aiding in strategic decision-making and process improvement. Dashboarding offers the advantage of developing tailored dashboards in-house without sharing data with third-party entities, ensuring full control over key information.
