This document discusses techniques for improving project estimation and management based on the Critical Chain Method. It begins by outlining common pain points in IT projects such as going over budget, delays, and scope creep. It then analyzes three main reasons for these issues: multitasking between tasks, leaving work until deadlines approach, and using buffer time instead of estimates. The document proposes three "painkiller instruments" to address these: reducing work in progress to focus on fewer projects, using a project buffer according to critical chain methodology, and monitoring buffer consumption. Implementing these changes could dramatically increase the number of on-time projects without extra resources.
