This book is for all financial professionals whose work, to a greater or lesser degree, involves complex spreadsheets and financial models. This includes investment bankers, commercial banks, accountancy firms, property firms, public sector including local government and healthcare, PFI/PPP enterprises, financial managers and financially literate general managers. Junior/middle management, where the focus would be on cash flow forecasting and budgeting tasks, will also find this book of value. For the vast majority of people involved in this subject, financial modelling is an activity, a task requiring skills. Once people have the ability to structure the model, they have a better starting point from which to address the financial problems. This new book proposal intends to offer that starting point. Theory is limited to the absolute essentials that aid understanding; thus the focus with this new book is very practical - this is how-to-do-it, showing best practice, and is illustrated with many practical worked examples.
