What are the key differences between software engineering and system engineering?

• Software engineering is not part of system engineering

• Software engineering encompasses the entire software development process, while system engineering is focused on the development of networks, people, databases, software, and hardware.

• Software engineering deals with all aspects of computer-based system development

• Software engineering is not a systematic process

• Client& Employer

• Judgement

• Profession

• Cost and Timeline

Define legacy challenge

• Challenge of maintaining & updating legacy software in such a way tat excessive costs are avoided and essential business services continue to be delivered

• challenge of developing techniques to build dependable software which is flexible enough to cope with different types of computer and support system

• challenge of shortening delivery times for large & complex without compromising system quality

What is software maintenance and why is it important?

• Software maintenance is a one-time task and does not require ongoing attention.

• Software maintenance is primarily focused on adding unnecessary features to the software.

• Software maintenance is crucial for keeping software applications running smoothly and meeting user needs over time.

• Software maintenance is only necessary for new software, not existing applications.
