All scheduling software is difficult to learn for a number of reasons. None have the optimal settings when installed and Layouts, User Preferences and default options need to be adjusted to obtain the best possible performance. Usually the Help files do not connect the user to real life situations and do not explain the practical use of functions. Furthermore, there are many flicks and switches with obscure names that are difficult to understand or decide what they do or which are important. These issues make learning the software very difficult without a comprehensive guide written by an experienced user. Investing in a book written by Paul E Harris will address all these issues and allow you to setup the software properly and understand all the obscure functions letting you become productive more quickly and enhance your career opportunities and salary with a solid understanding of the software.This book is an update of the author's Primavera P6 Version 8 to 21 book and has been written so it may be used with any software industry version.
