What is the Rational Unified Process?

• P. Krutchen answers this from several
  perspectives in his Rational Edge article
• What is the purpose of the RUP?
• a software engineering process
• guides software development organizations in
  their endeavors
• How is the RUP designed and delivered?
• process product
• integrated with the Rational suites of software
  development tools
• What is the structure of the RUP how is it
  organized internally?
• has a very well-defined and regular structure
  (phases, workflows)
• uses an object-oriented approach for its
  description
• How would an organization proceed to adopt the
  RUP?
• tailor or extend the RUP to match its specific
  needs
• What will I find in the RUP?
• captures best practices harvested by Rational
  over the years

What is the Rational Unified Process?

• Purpose of RUP
• Organizations have become aware of how important
  a well-defined and well-documented software
  development process is to the success of their
  software projects
• The development of the CMM (Capability Maturity
  Model) by the Software Engineering Institute
  (SEI) has become a standard to which many
  organizations look
• Some organizations have collected their knowledge
  
• design methods, textbooks, training programs,
  how-to notes
• unfortunately, in practice, these internally
  developed processes rapidly become obsolete, and
  almost never followed
• Other organizations have little or no process at
  all
• need a starting point
• The RUP can help both kinds of organizations, by
  providing them with a mature, rigorous, and
  flexible software engineering process.

What is the Rational Unified Process?

• RUP Is a Process Product
• designed and documented using the Unified
  Modeling Language (UML)
• delivered online using Web technology
• easy to access
• regular upgrades are released
• process is never obsolete
• users benefit from the latest development
• All team members access the same version of the
  process
• modular and in electronic form
• can be tailored and configured to suit the
  specific needs of a development organization
• integrated with the many software development
  tools in the Rational Suites
• developers can access process guidance within the
  tool they are using

What is the Rational Unified Process?

• RUPs Architecture
• underlying object-oriented model, using UML
• overall architecture has two structures or, if
  you prefer, two dimensions
• The horizontal dimension represents time and
  shows the lifecycle aspects of the process as it
  unfolds
• The vertical dimension represents core process
  disciplines (or workflows), which logically group
  software engineering activities by their nature

What is the Rational Unified Process?

• the horizontal dimension represents the dynamic
  aspect of the process
• cycles, phases, iterations, and milestones
• a software product is designed and built in a
  succession of incremental iterations
• Early testing and validation of design ideas
• Early risk mitigation
• The vertical dimension represents the static
  aspect of the process described in terms of
  process components activities, disciplines,
  artifacts, and roles

What is the Rational Unified Process?

• Adopting the RUP
• process framework can be adapted and extended to
  suit the needs of an organization
• can also modify, adjust, and expand the Rational
  Unified Process to accommodate the specific
  needs, characteristics, constraints, and history
  of its organization, culture, and domain.
• The process elements that are likely to be
  modified, customized, added, or suppressed
  include artifacts, activities, workers, and
  workflows as well as guidelines and artifact
  templates
• Starting in 2000, the RUP contains several
  variants, or pre-packaged development cases for
  different types of software development
  organizations.

11
What is the Rational Unified Process?

• RUP Captures Current Best Practices
• Develop software iteratively
• Manage requirements
• Use component-based architectures
• Visually model software
• Continuously verify software quality
• Control changes to software

12
What is the Rational Unified Process?

• RUP Software Architecture
• Architecture activities the 41 view
• logical view
• object model of the design (when an
  object-oriented design method is used)
• process view
• captures the concurrency and synchronization
  aspects of the design
• physical view
• describes the mapping(s) of the software onto the
  hardware and reflects its distributed aspect
• development view
• describes the static organization of the software
  in its development environment
• use case view
