This book focuses on several management science modeling problems and explains clearly how to implement them with Excel.
Winston teaches you how to employ standards (colors, borders, etc) to make your spreadsheet more professional. You will learn much about Excel even if you are not interested in management science models.
Contrary to Optimization and Operations Research books, it does not worry about algorithm details, being directed mainly to develop the student modeling skills.
Then, if your goal is to find a text that contains excel-based ways of solving managerial problems, and you are not concerned with solver details (simplex method, transport algorithms, nonlinear programming algorithms, interior point methods) this book is for you.
Another information: Chris Albright has a Modeling book directed to people that want to learn how to use VBA in modeling, that is, if you are a "want to be advanced" Excel user. He says that his VBA book is the natural next step to "Practical Management Science".
