This new quantitative text is the first to be written specifically for management students and practitioners and places a much greater emphasis on competency and work-based assessment. It goes beyond improved presentation of quantitative material covered in other texts to consider the genuine needs of the manager. Its user-friendly approach helps to dispel the characteristic fear of all things mathematical by relating concepts and assignments to the student's work experience. The design and conception of this package, consisting of a book and accompanying disk of Lotus models, is aimed particularly at managers taking the certificate or diploma in management. It is problem based and enables the reader to become comfortable with the subject matter and competent in the tasks set out in the text.
