Book excerpt: Most large companies worldwide today have some kind of shared services concept in place. Over half of the medium and large companies are currently engaged in some kind of shared service project activity. The investment in shared services is always calculated in millions. In other words, the costs of getting it right (or getting it wrong) can be huge. Shared Services in Finance and Accounting is a concise blueprint for identifying, assessing, designing, implementing and improving the process for shared services in the finance and accounting function. Tom Bangemann focuses on critical success factors, the people issues involved, and learning from other people's big mistakes. The book includes a variety of real life examples and real benchmarking data, performance metrics and best practices. The section on implementation is based on a proven five-phase methodology and explains the steps and activities involved as well as showing examples of the deliverables and the results you can expect. Any CEO, MD, CFO, Finance Director and senior finance people will find this book a 'must-have' guide to the process before they start and an excellent benchmark against which to measure the performance of any existing shared service operation.
