3. Introduction
What is RUP?
Iterativesoftware development process framework created by the Rational Software Corporation.
Why RUP?
Adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs.
It combines the experience base of companies to articulate 6 best practices:
iterative development
requirements management
employment of a component-based architecture
modeling software visually
Continuous verification of quality
Control change control.
Tailorable process that guides development, has tools that automate that application, & services that accelerate the adoption of those processes & tools.
Capability Patterns-Add/Remove chunks of Processes + Modify to address needs.
Ready to use Delivery Processes-quick starting point for planning & initiating a project.

5. Features of RUP
Architecture Centric with 4+1 Views of an architecture:
Logical: the functionality as seen by the end user
Implementation: the system as seen by the programmers
Process: view seen by system integrators
Deployment: view seen by system engineering to be used for installation and delivery
Use-Case: the high level use-cases that drive the architecture
Use-Case-Driven
Iterative Development
Configurable
Supported by tools

14. RUP-Building Blocks The RUP uses four elements to describe processes:
Workers – describe a role, some people have many roles.
Activities – small, definable, reusable tasks that can be allocated to a single worker.
Artifacts – usually process deliverables, like: use cases, code, plans, test cases, test results.
Workflows – coordinated sequences of activities.
There are 9 workflows, 6 engineering workflows:
Business modeling, Requirements, Development & Analysis, Implementation. Test, Deployment.
And 3 supporting workflows:
Project management, Configuration and Change Management, Environment.

22. Core Workflows Workflow Goal Business Modeling
Document business processes using business use cases.
Requirements
Describe what a system should do (elicit, organize, document required functionality, constraints, track & document trade-offs & decisions).
Analysis & Design
System will be realized in implementation phase.
Implementation
To define organization of code(subsystems), implement classes & objects(components), test components as units, integrate results from implementers/teams into an executable system.
Test
Verify interaction between objects, integration of components, requirements have been correctly implemented, identify & ensure defects are addressed prior to deployment.
Deployment
Producing external releases, packaging, distributing, installing, providing help & assistance to users.
Project Management
Framework for managing software intensive projects, practical guidelines for staffing, executing & monitoring projects, manage risk.
Configuration & Change Management
Manage multiple variants of evolving software systems, tracking versions, performing builds, enforcing site-specific development policies, perform change request management.
Environment
Provide software development organization with software development environment - processes + tools to support the development Team.

24. RUP – Work Components & Work Products
Work products involve: Iteration Assessment, Project Measurements, Periodic Status Assessment, Work Order & Issues List.
RUP is like an online mentor that provides guidelines, templates, and examples for all aspects and stages of program development.
The RUP development methodology provides a structured way for companies to envision & create software programs.

25. RUP Related Frameworks
OpenUP(OpenUP): is a part of the Eclipse Process Framework (EPF), an open source process framework developed within the Eclipse Foundation. Its goals are to make it easy to adopt the core of the RUP / Unified Process.
Agile UP: simplified version of the IBM Rational Unified Process (RUP) developed by Scott Ambler.[1] The AUP applies agile techniques including test driven development (TDD), Agile Modeling, agile change management, and database refactoring to improve productivity.
EssUP: you can pick those practices that are applicable to your situation and combine them into your own process.
UPEDU:software development process specialized for education, developed by Pierre-N. Robillard (École Polytechnique de Montréal), Philippe Kruchten (Rational Software) and Patrick d'Astous (École Polytechnique de Montréal).
ITUP: knowledge base of widely accepted industry best practices and the accumulated experience from IBM's client engagements.
Oracle Unified Method: plan-based method – that includes extensive overview material, task and artifact descriptions, and associated templates – the method is intended to be tailored to support the appropriate level of ceremony required for each project which is used by Oracle employees, customers & partner networks.

29. Advantages of RUP
This is a complete methodology in itself with an emphasis on accurate documentation
It is proactively able to resolve the project risks associated with the client's evolving requirements requiring careful change request management
Less time is required for integration as the process of integration goes on throughout the software development life cycle.
The development time required is less due to reuse of components.
There is online training and tutorial available for this process.

30. Disadvantages of RUP
The team members need to be expert in their field to develop a software under this methodology.
The development process is too complex and disorganized.
On cutting edge projects which utilise new technology, the reuse of components will not be possible. Hence the time saving one could have made will be impossible to fulfill.
Integration throughout the process of software development, in theory sounds a good thing. But on particularly big projects with multiple development streams it will only add to the confusion and cause more issues during the stages of testing

32. Relevance to CS577 & Conclusion
The iterative Phases of RUP find application in ICSM Spiral Model Life-Cycle phases & milestones.
The core workflows of RUP are incorporated as activities in ICSM.
The management workflows (PM,CCM & ENV) of RUP could be incorporated in ICSM.
The RUP related frameworks could be adopted for a particular project (domain) that plans to use ICSM.
The Best Practices upon which RUP was built are now the pillars on which ICSM rest.
Conclusion: RUP provides a unified Software Process Model as a Framework in which team members have access to the same large knowledge base of guidelines, templates, tools, and other items to ensure that they share the same language and perspective on the project. RUP development methodology provides a structured way for companies to envision & create software programs. Since it provides a specific plan for each step of the development process, it helps prevent resources from being wasted and reduces unexpected development costs. By incorporating many more features of RUP, ICSM can be tailored to be a better process to design Software & Systems.
