Is Rational unified process still used?

For me, RUP is as alive as COBOL is and if you can still find a company that actively uses it, you'll probably find that they still use COBOL, too.

What are the advantages of unified process?

Advantages of Rational Unified Process Emphasizes the need (and proper implementation of) accurate documentation. Diffuses potential integration headaches by forcing integration to occur throughout development, specifically within the construction phase where all other coding and development is taking place.

Is RUP agile or waterfall?

But unlike waterfall, RUP is an iterative process. The three strategies captured by RUP are a customizable process that guides development, automated tools to expedite the process, and services that help to adopt process and tools faster.

How many phases are there in Scrum?

There are 3 groups of Scrum phases and processes namely pregame, game, and post-game. These are different from the waterfall, spiral, and iterative model. The waterfall methodology has the following phase such as planning and developing phases.

Why is software maintenance expensive?

But why does maintaining that software cost so much? Here are some of the reasons: Software by its nature is constantly evolving. Not only do users ask for new and modified features, but the systems on which the software runs keep changing, so the software has to be modified to fit new environments.

Why software costs are more to maintain than it does to develop?

Software costs more to maintain than it does to develop. Explanation: For systems with a long life, maintenance costs may be several times development costs. ... Explanation: Cost of a software is a management issue & is not related to process activities.

What are the four dimensions of dependability?

What is a FRD?

The functional requirements document (FRD) is a formal statement of an application's functional requirements. It serves the same purpose as a contract. The developers agree to provide the capabilities specified. The client agrees to find the product satisfactory if it provides the capabilities specified in the FRD.
