A software product can be recognized by what it offers and how well it can be used.

This software must satisfy on the following grounds:
1.  Operational
2. Transitional
3. Maintenance

Well designed and engineered software is expected to have the following characteristics:

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
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
