This document discusses challenges that organizations face when implementing ITIL (Information Technology Infrastructure Library) frameworks. It identifies eight key sources of challenges: 1) lack of senior management commitment, 2) difficulties managing organizational changes, 3) implementing the wrong scope, 4) insufficient competency of IT staff, 5) poor project methodology and governance, 6) weak management of communication, 7) failure to consider all stakeholders, and 8) low quality of any consultancy firms involved. The document provides examples and explanations for how each of these challenge sources can negatively impact an ITIL implementation project.
