• Enablegood communications between participants in a project
  
  

SSADM uses waterfall model of development

• Feasibility Study - Feasibility Report
• Investigation of the current environment - Initial System Requirements 
• Provide Business systems options - Business Cost / Benfits
• Definition of System requirements - Requirement Specification
• Provide Technical system options - Technical Cost / Benfits
• Logical design - Information Flow, Data Flow Diagram, Data Design, Process Design
• Physical design - Equipment, Networks, Training etc
  
  

For each stage, SSADM provides
techniques and procedures, and conventions for recording and communicating information both in textual and diagramatic form.
