The need for software development arises from the higher rate of change in user requirements and the environment in which the software runs.
Big software. It is easier to build a wall than a house or building, just as the size of the software becomes large, and engineering has to do the scientific process.
Scalability – If the software process is not based on science and engineering concepts, it would be easier to recreate new software than to scale existing software.
Costs. As the hardware industry has demonstrated its prowess, and huge manufacturing has lowered the price of computer and electronic equipment. But the cost of software remains high if the proper process is not adapted.
The dynamic nature of . The ever-growing and adapting nature of software is highly dependent on the environment in which the user works. If the nature of the software is constantly changing, new improvements must be made to the existing one. This is where software development plays a good role.
Quality Management – A better software development process ensures a better and higher quality software product.
Characteristics of good software.
A software product can be judged by what it offers and how well it can be used. This software must satisfy the following grounds:
operational
transitional
maintenance
A well-designed and built software is expected to have the following characteristics:
Operational
This tells us how well the software performs in operations. This can be measured on:
Budget
Usability
EFFICIENCY
correctness
functionality
reliability
security
safety
transitional
This aspect is important when software moves from one platform to another:
Portability
Interoperability
reusability
adaptability
maintainability
This aspect summarizes how well the software can maintain itself in an ever-changing environment:
Modularity
maintainability
flexibility
Scalability
In short, software development is a branch of computer science that uses well-defined development concepts necessary to create software products that are efficient, reliable, scalable, budget-friendly, and timely.
