Introduction

Question 1

What caused the mars climate orbiter to disappear? What did it cost?

Answer 1

Lockheed Martin used US units, while the contract with NASA expected SI units. It cost about $328 Million

Question 2

Why did GIRES fail? What did it cost?

Answer 2

Could not cope with changes to the requirements. It was allocated $80 million, but ended up costing $400 million in 5 years

Question 3

What was the original and end cost of the Canadian gun registry. Why this increase?

Answer 3

Original is $119M, but final was around $2B. Customers asked for over 2000 changes during the development period

Question 4

What 3 conclusions were met when key studies were performed about software development?

Answer 4

• Software development is highly unpredictable. Only 10% of projects are delivered within initial budget schedule
• Management has greater effect in success or failure than technological advances
• Too much software scrap and rework. Process is immature

Question 5

Over half of all software projects are completed and operational, but ________, ___________ or offers fewer features and functions than promised

Answer 5

over-budget, over-time estimate

Question 6

Why is software hard to develop?

Answer 6

It’s soft and can be programmed to do anything, but also gets easily out of hand
It’s intangible. People cannot see the product, and thus don’t know what they want.

Question 7

Writing code leads to less than __% of software development time

Answer 7

20

Question 8

Knowing how to code does not correlate to knowing how to develop ______.

Answer 8

software.

Question 9

How does the IEEE define software engineering?

Answer 9

The application of systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software; that is, the application of engineering to software

Question 10

Why are programmers not enough for software development?

Answer 10

Same reasons that bricklayers are not enough to build a skyscraper
Mechanics are not enough to build a new car

Question 11

What is the main goal of software engineering?

Answer 11

Develop and deliver software
On time
On budget
Feature complete

Question 12

What are the 4 project phases?

Answer 12

Inception: Establish scope, use cases, architecture, estimates for costs, and schedule
Elaboration: Define and validate architecture, baseline a detailed plan for the construction phase
Construction: Achieve useful versions, achieve adequate quality
Transition: Achieve final product baseline, achieve stakeholder concurrence of completeness
