Arthur D. Little conducted a global and cross-industry Digital Transformation Study in 2015, with over 100 global players participating. The study found that turning digital has become a well-understood imperative, but the path to transform adequately remains unspecified. The study assessed 1+7 sections and covered 7 major industry clusters, with expert interviews conducted with management representatives. The Digital Transformation Index (DTI) was used to measure progress in digital transformation, with 80% of surveyed companies being digital adaptive only. The major challenge for 50% of companies was perceived as a lack of digital knowledge across the value chain.
