Software Engineering Operations 1

Software life cycle?

The software life cycle consists of 3 periods: Software definition, software development and operation maintenance.

Waterfall Model:

Advantages:

It is advantageous to the organization and management of the personnel in the process of large-scale software development, which is beneficial to the research of software development methods and tools, thus improving the quality and efficiency of large-scale software project development.

Disadvantages:

The waterfall model is document-driven.

Range

A stable user demand project.

Rapid prototyping:

Advantages:

Helps ensure that users ' real needs are met.

Disadvantages:

Accurate prototyping is more difficult. Customers and developers have different understandings of prototypes.

Range:

Familiar with the development field, and have the project of developing prototype.

Incremental Model:

Advantages:

Can in a short period of time to submit to the user can complete part of the work of the product, gradually increase the product function can enable users to have more time to learn and adapt to new products.

Disadvantages:

Parallel development controls may run into risks. Flexibility makes it easy to degenerate into a model for edge modification, losing control.

Range:

Perform an existing product upgrade.

Spiral Model:

Advantages:

Design flexibility, can be modified at all stages of the project. Customers are always involved in all stages of development, ensuring the right direction of the project.

Disadvantages:

A significant risk assessment is required, with multiple iterations increasing costs and delaying submission times.

Range:

Large-scale software projects.
