Rational Unified Process Flashcards
RUP
Rational Unified Process
- A sample process model
- Captures many of the best practices in modern software development
- Designed for incremental software development
- Widely used
- Emphasizes the development and maintenance of (UML) models with sematically rich representations of the software system under development.
- IBM Course
RUP Phases
- Inception
- Elaboration
- Construction
- Transition
Inception Phase
- Establish project scope and boundary conditions
- Determine the use cases and primary scenarios that will drive the major design trade-offs
- Demonstrate a candidate architecture against some of the primaru scenarios
- Esimate the overall cost and schedule
- Identify potential risks (the sources of unpredictability)
- Prepare the supporting environment for the project.
Elaboration Phase
- Define, validate and baseline the architecture as rapidly as is practical.
- Baseline the vision
- Refine support environment
- Baseline a detailed plan for the construction phase
- Demonstrate that the baseline architecture will support the vision at a reasonable cost in a reasonable period of time.
Construction Phase
- Complete the software product for transition to production
- Minimize development costs by optimizing resources and avoiding unnecessary scrap and rework.
- Achieve adequate quality as rapidly as is practical
- Achieve useful vesions (alpha, beta, and other test releases) as rapidly as possible.
Transision Phase
- Achieve user self-supportability
- Achieve stakeholder concurrence that deployment baselines are complete and consistent with the evaluation criteria of the vision.
- Achieve final product baseline in a rapid and cost-effective manner.
What is an iteration?
A distinct sequence of activities with a baseline plan and evluation criteria resulting in a release (internal or external)
What is the duration of an iteration?
- Begins with planning and requirements and ends with an internal or external release
- Ideally should run from 2 - 6 weeks, depending on your project size and complexity.
- Factors that affect duration of an iteration:
- Size, stability, maturity of an organization
- Familiarity with the iterative process
- Size of the project
- Technical simplicity of project
- Level of automation used to manage code, distribute information, perform testing.
What is the rule of thumb for the number of iterations?
Use 6 +/- 3 iterations.
What is an iteration plan?
- An outline of an iteration plan.
- Contains an iteration schedule section for requirements discipline.
Concepts that drive iterative development
- Early mitigation of risk
- Early base-lining of architecture
- Use of objective metrics
What is the definition of risk?
An ongoing or upcoming concern that has a significant probability of adversely affecting the success of major milestones.
What are some risk types?
- Technical/Architectural Risks
- Unproven technology, uncertain scope
- Resource Risks
- People, skills, funding
- Business Risks
- Competition, ROI, supplier interfaces
- Schedule Risks
- Project dependencies
- Only 24 hours in a day
What is a Risk List Artifact?
An identification and prioritization of risks and risk types.
What is a direct risk?
A direct risk is when the project has a large degree of control.
