What is software engineering?

How would you define software engineering?

This is Q. 1 on today’s 372 quiz.

How does IEEE define software engineering (SE)? (1) The application of a systematic, disciplined, quantifiable

approach to the development, operation, and maintenance of software; that is, the application of engineering to software.

(2) The study of approaches as in (1).

See the Software Engineering Body of Knowledge -- http://www.swebok.org/ch1.html#Ref1

What do you think SE includes?

This is Q. 3 on today’s 372 quiz.

SWEBOK defines SE “knowledge areas”:Software requirementsSoftware designSoftware constructionSoftware testingSoftware maintenanceSoftware configuration managementSoftware engineering managementSoftware engineering processSoftware engineering tools and methodsSoftware quality

All these areas are addressed in your 37X curriculum at Rose!

What's a project?Chapter 1, pages 3-17

Hint - Basically, all engineering work is “projects”Why is that?

This is Q. 5 on today’s 372 quiz.

Let’s talk about projects!DefinitionProject parametersTriangleCreepsApplicationsClassifications

More about each of these…

We need a definition….A project is a sequence of unique, complex, and

connected activities having one goal or purpose and that must be completed by a specific time, within budget, and according to specification.

Let’s do one, in class, on teams!Here’s the problem… Jelleystone park wants to tag all

their grizzly bears so they can geo-locate them from the park rangers’ cell phones, as the rangers move throughout the park.

Define the basic steps of your team’s project that would accomplish this!

We’ll all report back in 15 minutes!

What role will you play?

Takes us back to Q. 4 on today’s 372 quiz.

What will you do on a team out in the “real world”?Starting SE’s or software developers on large

projects usually: Test & create tests Design & develop code

Starting SE’s or software developers on small projects usually:

Do a little of everything Including talking to “outsiders”
