FAST Phases are more detailsed than the classic phases:
Reference: SAD pg 71, 79

Reference: SAD pg 79
An Information Systems life cycle can be divided into two stages:
Two key events alters between the stages:
Reference: SAD pg 71
Assesses the maturity level of an organisation
Level 1: INITIAL (inconsistent methods)
Level 2: REPEATABLE (consistent project management)
Level 3: DEFINED (consistent process used)
Level 4: MANAGED (process managed & measured)
Level 5: OPTIMISED (continuous process improvement)
Reference: SAD pg 69
Systems Analysis & Design methods are required for developing information systems for businesses. In order to understand the processes fully, invest in the following book:
Systems Analysis & Design for the Global Enterprise 7th Edition
L.D. Bentley / J.L. Whitten
Published by McGraw-Hill/Irwin
ISBN-13: 978-0-07-110766-2

I refer to this edition often & recommend it to anyone interested in focusing on Systems Analysis & Design. It gives an overall picture & breaks the process down into easy to read chapters, identifying what stage the method refers to in the life cycle.
