Aspects of software development

---

Overview

• Analysis: Before the problem can be solved, the requirements of the new system must be gathered.
• Design: In the design phase key components of the project are designed and the overall structure of the project is planned.
• Development: In this stage the solution is developed.
• Testing: In this stage the developed software is tested and any bugs are fixed.
• Implementation: In this stage the last development stage is carried out and final testing is done.
• Evaluation: In this stage the software is evaluated and a post-implement review is carried out.

Analysis

The analysis stage is first stage of the software development cycle. In this stage the requirements and constraints of the new system are gathered.

Design

This stage is the planning of the project and designing the new system. In this stage the following is designed:

• processing
• Data structures
• outputs
• inputs
• user interface
• hardware

Testing

This stage is the testing of the software and fixing any bugs that are found.

Black box testing

Black box testing is testing that tests if the inputs and outputs of the program are expected.

Alpha testing

Alpha testing focuses on the checking the structure of the code.
