Let’s discuss Rational Unified Process in Software Engineering with the phases of RUP. There are four main phases of RUP;

1. inception
2. elaboration
3. construction
4. transition

What is the Rational Unified Process?

Rational Unified Process is also called RUP. RUP is a process for software development. The inventor of RUP is Rational Software Corporation.

RUP involves 4 phases;

• • Inception
  • Elaboration
  • Construction
  • Transition

What is the inception phase?

Inception phase involves the following activities;

• Requirements understanding and requirements description
• Maintaining Software Requirement Specification (SRS)
• Understand the business case of the system being developed.
• Describes the scope of the system.
• Describes the goals of the system.
• To identify the following  to interact with the systems initially;
  • External systems
  • People
  • Organizations

• To describe the followings initially;
  • Schedule
  • An estimate of the overall system
  • Risk assessment

What is the elaboration phase?

In the elaboration phase, we refine the requirements

It ensures the followings for the construction phase;

• • Standards
  • Guidelines
  • Processes
  • Tools
• Understanding of high priority risks
• Elimination of high-quality risks.

What is the Construction phase?

• To completely understand and describing the remaining requirements that were miss during inception and elaboration.
• Prepare the design of the system.
• To ensure the successful validation of the customer.
• To optimize the resources.
• To minimize the cost.
• To develop the versions of the system.

What is the Transition phase?

• Delivery of the overall system to the customer.
• Defects findings
• System modifications.
• Product installation
• Product release

What are the six best practices of rational unified process?

1. Manage requirements.
2. Develop iteratively.
3. Model visually.
4. Continuously verify quality.
5. Use component architectures.
6. Manage change.

Is Rational Unified Process Agile methodology?
Agile Unified Process (AUP) is considered as a simplified version of the Rational Unified Process (RUP.
