Acknowledgements
I would like to express my thanks to CelPlan Technologies, Inc. for allowing me to describe its planning methodology and to use CelPlanner Suite tool dialogs and screen shots to illustrate concepts and procedures.
I would like to express my gratitude to my daughter Cristine Korowajczuk, for revising my text and providing valuable comments and corrections throughout the book.
The methodology explained in this book was developed over the past twenty years by a group of CelPlan partners, mainly me, Aluisio Ribeiro, Leila Ribeiro, Paulo Leite and Wagner Mello.
I would like to express my gratitude to Paola Durant and Mary Rizzo, two excellent English teachers who spent time revising parts of my text.
