Software Development Framework

2. RUP Backstory
Was originally developed by Rational Software Corporation.
They are also the creators or Rational Rose and the UML Modeling Language.
They’ve been a division of IBM since 2003; purchased for 2.1 Billion.

3. Rational Unified Process (RUP)
RUP is an Object-Oriented program development methodology.
Rational states that it is an online mentor that provides guidelines, templates, and examples.
There is no 1 set of framework to be used in RUP, it is dynamic; to be able to it a large number of situations.
Process framework that can be tailored to a specific organization or project need.

4. RUP Terminology
Cycle: A development cycle is the period of time from the very start of the project until product release (or project cancellation); it includes all the activities that are executed during that time.
Phases: Each cycle of the RUP is broken down into a sequence of 4 stages called Inception, Elaboration, Construction and Transition. (More on this later)
Milestone: The point at which an iteration formally ends; corresponds to a release point.
Workflow: is a sequence of activated that produces a result of observable value.

5. RUP Terminology Cont.
Iteration: Inside each phase there may be one or more iterations. Software is developed in each iteration, which is concluded by a minor milestone, including a release (internal or external) that is a point for assessing the project progress.
The primary goal of each iteration is to slowly chip away at the risk facing the project, namely: Performance risks, integration risks, conceptual risks (design flaws).
The result of a single iteration is an incremental improvement of the system.

6. Phases of RUP Inception Elaboration Construction Transition
RUP is broken into four phases of development, each of which is organized into a number of separate iterations that must satisfy defined criteria before the next phase is undertaken.
Inception
Elaboration
Construction
Transition

8. Inception Phase
Build a good understanding of the requirements and scope of the system
Initial requirements captured
Cost benefit analysis
Initial risk analysis
Defining a candidate architecture

9. Elaboration Phase
Use Case Analysis- Sequence and collaboration diagrams
Domain Model- To understand the problem. (System requirements are within this context)
Risk Assessment Plan revised
Developers analyze the project's needs in greater detail and define its architectural foundation

10. Construction Phase
This phase is concerned with moving from the executable architecture created in the elaboration phase to an operational system
The focus here is to develop the application to the point where it is ready for deployment
Focus is on implementation and design; developers create the application design and source code

11. Transition Phase Also known as the termination phase
Development team begins to shrink
Control is moved to maintenance team
Deliver System into production

12. Cons of RUP
The process may be too complex to implement in certain cases
Development can get out of control
It’s a heavyweight process
You need an expert to fully adopt this process

13. Pros of RUP Regular feedback from stakeholders
Efficient use of resources
You deliver exactly what the customer wants
Issues are discovered early in your project
Supports iterative development
Improved risk management
