2.Object Oriented Software Development Process

Question 1

In Object Oriented Development Approach we focus on structure and how the individual concept behave. That means object oriented development aproaches must be?

Answer 1

1. Use Case Driven
2. Architecture Centric
3. Iterative and Incremental

Question 2

Explain what does Use Case Driven means in Object Oriented Development Process

Answer 2

They are used to define which actors use the system and how they behave or interact with the system. This can be used to communicate requirements as well.

Question 3

Explain what does Architecture Centric means in Object Oriented Development Process

Answer 3

An architecture of the system is the structure of the system. It drives system specification, documentation and construction.

Question 4

What are the 3 architectural views ?

Answer 4

1. Functional - External
2. Structural - Static (describes in terms of classes, relationships, attributes, methods)
3. Behavioural - Dynamic (describes behaviour in terms of message passing among objects and changes an object goes through)

Functional- Describe the system behaviour from user perspective.

Question 5

Benefits of OOAD?

Answer 5

1. Decomposes system into managable modules.
2. Easy to communicate to users.
3. Since modularized, integration with other technologies is easy.
4. Modularization allows parts to be reused.
5. Data hiding concept allows us to create systems with tamper proofing.

Question 6

What are the phases of RUP (Rational Unified Process)

Answer 6

1. Inception - Establishes the business case for the system.
2. Ellaboration - Develop an understanding of the problem domain and the system architecture.
3. Construction - System design, programming and testing.
4. Transition - Deploy the system in its operating environment.

Question 7

What are the 2 types of iterations in RUP (Rational Unified Process)?

Answer 7

1. In-phase iteration - Repeat activities within a phase.
2. Cross-phase iteration - All the 4 phases are repeated.

4 Phases - Inception, Ellaboration, Construction, Transition

Question 8

What are the 2 categories of workflows in RUP?

Answer 8

1. **Engineering Workflows **- Which help to produce technical product (Software itself)
2. **Supproting Workflows **- Focuses on the managerial aspects of information system developments

Question 9

What are the workflows in RUP?

Name all 9 workflows. (6- Engineering/3-Supporting)

Answer 9

1. Business Modelling
2. Requirements
3. Analysis and Design
4. Implementation
5. Testing
6. Deployment
7. Configuration and change management
8. Project management
9. Environment

1-6 is Engineering workflows / 7-9 is supporting workflows

Question 10

What are the primary deliverables of the inception phase?

Answer 10

The primary deliverables of the inception phase include a vision document, primary requirements and constraints, an initial use case model, feasibility and risk assessment, project plan and milestones, and prototypes.

Question 11

Which activities takes place in Ellaboration phase?

Answer 11

1.Finalizing business case.
2.Risk assessment & eliminating risk.
3.Establish & validate system architecture.
4.Complete the project plan with sufficient details.
5.Gathering some amount of requirements and building the UML diagrams.

Question 12

What are the primary deliverables of Ellaboration phase?

Answer 12

1.UML structure & behaviour diagrams.
2.Description of the software architecture.
3.An executable, a baseline version of the evolving information system.
4.Devised business case and risk list.

Question 13

Explain construction phase in RUP

Answer 13

• Focuses heavily on programming
• Implementation workflow happens here.
• In the last iteration of construction phase, deployement workflow takes place.

Question 14

What is the primary deliverable of the Construction Phase?

Answer 14

Software product & programming code

Question 15

Explain Transition phase in RUP

Answer 15

• Primary focus is ontesting & deploying workflows however, some level of implementation takes place.
• Some re-design work maybe necessary but they have to be very minimal.

Question 16

Which activities takes place in Transition Phase?

Answer 16

1. Beta & Acceptance testing.
2. User Training.
3. ROlling out the software to production platform.

Question 17

What is the primary deliverable of the Transition Phase?

Answer 17

1. Executable system.
2. User Manual & training documents.
3. Platform specific information.

Question 18

What are the UML diagrams used in Inception phase?

Answer 18

Use Case

Question 19

What are the UML diagrams used in Ellaboration phase?

Answer 19

• Use case
• Sequence & Communication
• Object
• Class
• State

Question 20

What are the UML diagrams used in Construction phase?

Answer 20

• Component (Compile time dependencies)

Question 21

What are the UML diagrams used in Transition phase?

Answer 21

Deployment

Question 22

Name workflows in each phases for RUP

Answer 22

1.Inception- Business Medeling, Requirements.
2.Ellaboration- Requirements, Analysis, Design, Implementation,Testing
3.Construction-Design, Implementation,Testing
4.Transition- Testing, Deployment

Testing happens throughout the process, It’s iterative & must be done parrallel to implementaion.

Question 23

What is the purpose of the Business Modeling Workflow?

Answer 23

The purpose of the Business Modeling Workflow is to uncover problems, identify potential projects, and ensure that both developer and user organizations understand how the information system fits into the business processes.

Question 24

What is the primary purpose of the Implementation Workflow?

Answer 24

The primary purpose of the Implementation Workflow is to create an executable solution based on the design model, including writing new classes and incorporating reusable classes from executable class libraries into the evolving solution.

Question 25

What is the primary purpose of the Testing Workflow?

Answer 25

The primary purpose of the Testing Workflow is to increase the quality of the evolving system through unit testing, integration testing, user acceptance testing, and alpha testing. Testing should go on throughout the development of the system.

Question 26

What activities are included in the Deployment Workflow?

Answer 26

The Deployment Workflow includes software packaging, distribution, installation, and beta testing.

Question 27

What is the purpose of the Project Management Workflow?

Answer 27

1.Identify & manage the scope. 2.Estimate the time to complete each iteration & entire project. 3.Estimate the cost of individual iteration and entire project. 4.Tracking the progress being made towards the final evolving of information system.

Question 28

What is the purpose of the Environment workflow?

Answer 28

1. Managing the software tools to support the team. 2. CASE tools are developed and used.

Question 29

What are the supporting workflows in the Unified Process?

Answer 29

The supporting workflows in the Unified Process include project management, configuration and change management, and environment workflows.

Question 30

What are the engineering workflows in the Unified Process?

Answer 30

The engineering workflows in the Unified Process include business modeling, requirements, analysis, design, implementation, test, and deployment workflows.
