What are the attributes of a good software? What makes software good?
It is a known fact that writing good software is hard. This is because writing good software often requires a strict adherence to the software development process. The software development process is mainly in 7 phases; Planning, Analysis, Design, Development, Testing, Implementation and Maintenance. While many software developers today will skip some of these 7 steps, they are all very crucial in the delivery of a good software.
In this post, we dive into the essential attributes of a good software.
What are the attributes of a good software:
1. Functionality: This is a very important feature of a good software. A good software must deliver on its promises; must do what it is expected to do. The features highlighted in the software specifications document must be fully implemented for a software to be said to be functional. A software that meets the functionality requirement is well on its way to becoming a good software.
2. Usability and User experience: Does the software appeal to the end users? The users’s perception of a software’s usefulness, useability and desireability based on their interaction with the software is a deciding factor on whether a software is good or not. A good software is intuitive by design, and this makes for a good user experience.
3. Performance and Efficiency: A good software must be perform its tasks in a timely manner; one that meets the business and end-user’s expectations. A good sofware would typically only use the minimum resources needed to complete a given task and nothing more.
4. Reliability: A good software must be immune to failure at least to a large extent. A reliable system will rarely fail. In the event of software failure, a good software will have mechanisms in place to recover gracefully from the failure as soon as possible. All software is prone to fail at some point, but a good software will be able to recover quickly with minimal negative impact.
5. Maintainability: Software should evolve very quickly, as requirements change very quickly. A good software is one that is maintainable; it should be possible to add new features to a software when the business requirements change. The easier it is to make changes to a software, the better the software is overall.
6. Security: An ideal software is one that is secure. A secure software will usually incorporate security into every phase of the Software Development Life Cycle (SDLC). This ensures the overall integrity of the developed software. A good software will not expose its users to risks.
7. Understandability at the code level: From a system design perspective, a good software should be easy to understand. This makes it easy to make changes, patch defects and expand on the system as the software evolves. Having an easy to understand software codebase is crucial if software is to be called a good software.
8. Good economic value: The design and development costs of software should not be so high that it outweighs its business value. A good software brings economic value to the business.
Software has a lot of moving parts. It is therefore important to maintain the best quality at every software development step - from the planning stage to the software implementation and delivery stage.
