Software Development Life Cycle Sdlc Questions Medium
During the Software Development Life Cycle (SDLC), various types of software defects can be identified. These defects can be categorized into the following types:
1. Functional Defects: These defects occur when the software does not perform its intended function correctly. It may include issues such as incorrect calculations, missing or incorrect data validation, or improper handling of user inputs.
2. Performance Defects: Performance defects refer to issues related to the software's speed, responsiveness, or resource utilization. It may include problems like slow response times, excessive memory consumption, or inefficient algorithms.
3. Usability Defects: Usability defects arise when the software is difficult to use or understand for the end-users. It may include issues like confusing user interfaces, unclear instructions, or lack of intuitive navigation.
4. Compatibility Defects: Compatibility defects occur when the software does not work correctly with other systems, platforms, or devices. It may include problems like software crashes on specific operating systems, incorrect rendering on different browsers, or incompatibility with certain hardware configurations.
5. Security Defects: Security defects refer to vulnerabilities or weaknesses in the software that can be exploited by malicious users. It may include issues like inadequate data encryption, improper access controls, or susceptibility to hacking or data breaches.
6. Documentation Defects: Documentation defects occur when the software's documentation, such as user manuals or technical guides, contains errors or lacks necessary information. It may include issues like outdated instructions, incorrect diagrams, or missing details.
7. Maintenance Defects: Maintenance defects are defects that arise during the maintenance phase of the SDLC. It may include issues like incomplete bug fixes, regression errors, or unintended side effects of code modifications.
8. Interface Defects: Interface defects occur when there are problems with the interaction between different software components or external systems. It may include issues like incorrect data exchange formats, incompatible APIs, or communication failures.
It is important to identify and address these defects during the SDLC to ensure the development of high-quality software that meets the desired requirements and expectations.
