Xperience Level Agreement (XLA)® is the framework and commitment to apply XM in tech- driven organizations and ecosystems. The three technology management philosophies that influenced our way of working are Lean, ITIL, and Agile. XLA is the missing piece of the puzzle. Why? In just two words: Lean is "No Waste", ITIL is "No Chaos", Agile is "No Delay", and XLA is "No Frustration." XLA® fosters curiosity, empathy, and courage to be customer-centric. This pocketbook explains the XLA framework and its practical use. We added a glossary to ensure we are all on the same page. This book is for those with an open mindset in IT, tech, outsourcing, and digital transformation. Tech can drive us crazy and delight us. The omnipresence of digital technology underlines the need for Experience Management (XM). XM is the discipline of designing, measuring and improving the experiences provided to customers, employees, and other stakeholders.
