Unit 1: The Evolving Role of Software

Problems with cost Notes
Problems with quality.

Software Development Problems

Software is becoming larger and more complex, e.g. the code in consumer products is
doubling every couple of years.

Many software products have poor quality, e.g. Software testing typically finds 25 defects
per 1000 lines of code.

Software development is costly, e.g. Development of the FAA’s Advance Automation
System cost over $700 per line of code.
Serious scheduled overruns are common, e.g. One in four large-scale development projects
is never completed.

Challenges to the Profession

Serious problems in software development associated with cost, quality, and scheduled
still remain.

Although improving, the software engineering profession is still viewed as immature;
and many organizations still have ad hoc software development process.
The initial professional education of engineers is critical to the advancement of the discipline.
