Proper balance between support and control

CM function is flexible and can accommodate the changing needs and requirements

Question 7

Reasons for CM

Answer 7

Requirements creep

Multiple copies

Shared data

Simultaneous updates

Question 8

What is requirement creep

Answer 8

Occurs when there is a difference between the original design and the final product

Question 9

What is the greatest source of time and cost overrun

Answer 9

Requirements creep

Question 10

What is a simple tool for controlling requirement creep

Answer 10

Statement of work, an agreement between consumer and developer on what will and will not be built in a particular iteration of development

Question 11

Why would CM help if there are multiple copies?

Answer 11

It documents of all the different software that use similar/same code that you changed/fixed.
If one method you wrote needs to be changed, you know every place that code was

Question 12

Why would CM help if there is shared data?

Answer 12

When multiple programmers are working on serval modules of a program, changes made in one module can affect operation of another module. Documents changes that would affect other peoples work, so they know what is happening

Question 13

Why would CM help if there are simultaneous updates?

Answer 13

Protects against two people changing the code overwriting each other.

Question 14

Primary goal of CM

Answer 14

Maximize productivity by minimizing mistakes

Question 15

Answer 16

Coding phase

Question 17

CM goals during testing phase

Answer 17

1. Continue minimizing divergence
2. Having programmers find and fix bugs quickly
3. Build a project baseline of accurate and consistent code

Question 18

Best way to have programmers find and fix bugs quickly

Answer 18

By letting programmers do their job with independence and stability

Question 19

Answer 19

1. Maintain the accuracy and consistency of baseline
2. Keep track of corrected and outstanding bugs
3. Prepare the best state of software for delivery

Question 24

The Control function of CM does what?

Answer 24

1. Locks down the specifications, documents , drawings, requirements, tools, software, and other deliverables associated with the project
