Inception Know What to Build

• Prepare vision document and initial business case
• Include risk assessment and resource estimate
• Develop a vision of project requirements
• Initial use-case and domain models (10-20

• Manage project scope
• Reduce risk by identifying all key requirements
• Acknowledge that requirements will change
• Manage change, use iterative process

UPM(Unified Process Model)

• UPM is used to describe a concrete software
  development process or a family of related
  software development process.
• UPM and Rational Unified Process
• UPM is a process meta-model for defining
  processes and their components
• RUP is a process model
• May 12, 2000 OMG submitted by
• IBM, Rational Software, SofTeam, Unisys, Alcatel
• Etc
• The purpose of the UPM is to support the
  definition of processes including processes such
  as RUP that mandate the use of UML.
