The AL Dhakaliya Software development team is currently working on a new application
development project. An initial study has determined that the size of the program will be
roughly 90,000 delivered source instructions (DSI). According to the project head, this
project should be considered as embedded software project.

In the software business, the phrases "cohesion" and "coupling" are sometimes used interchangeably.
Does this suggest that software developers have a responsibility to produce code that can be maintained even if their employers do not require them to do so?

- Software engineering is a field of engineering which is concerned with all aspects of software production. Softwareengineering is the “application of a systematic, disciplined, quantifiable approach to the design, development, operation,and maintenance of software. Software engineers are people who are trained and skilled in the optimal use of softwareengineering practices to produce high quality software. Software engineers, therefore, are not just computer programmers;they may be programmers, but they also have a thorough understanding of the principles of software engineering, and thecomplete life-cycle activities of a software development project, such as software specification, software development,software validation, and software evolution. In your role as a software engineer, you will have to advise the development team on various software engineering aspects. 1.
