A software product can be judged by what it offers and how well it can be used. This software must satisfy on the following grounds:
● Operational
● Transitional
● Maintenance
Well-engineered and crafted software is expected to have the following characteristics:
Operational
This tells us how well software works in operations. It can be measured on:
● Budget
● Usability
● Efficiency
● Correctness
● Functionality
● Dependability
● Security
● Safety
Transitional
This aspect is important when the software is moved from one platform to another:
● Portability
● Interoperability
● Reusability
● Adaptability
Maintenance
This aspect briefs about how well a software has the capabilities to maintain itself in the ever-changing environment:
● Modularity
● Maintainability
● Flexibility
● Scalability
In short, Software engineering is a branch of computer science, which uses well-defined engineering concepts required to produce efficient, durable, scalable, in-budget and on-time software products.
