1. | What is the main challenge in estimating the cost of a software development project? |
Discuss |
Answer: (c).Difficulty in accurately estimating the costs up front
Explanation:Getting reliable cost and schedule estimates for software development projects is still largely a dream.
|
2. | What is the main factor used in most cost estimation models for software development projects? |
Discuss |
Answer: (c).The effort required for the project
Explanation:In most cost estimation models, a simple relation between cost and effort is assumed.
|
3. | What is the definition of total cost in the context of software development projects? |
Discuss |
Answer: (b).The cost of initial software development effort only
Explanation:The notion of total cost is usually taken to indicate the cost of the initial software development effort.
|
4. | What does the term "development time" refer to in the context of software development projects? |
Discuss |
Answer: (a).The time between the start of the requirements engineering phase and the point in time when the software is delivered to the customer
Explanation:Development time will be taken to mean: the time between the start of the requirements engineering phase and the point in time when the software is delivered to the customer.
|
5. | What do most cost estimation models assume about the relationship between cost and effort? |
Discuss |
Answer: (c).A simple linear relationship
Explanation:Most cost estimation models assume a simple linear relationship between cost and effort, where effort is usually measured in man-months and the total cost is calculated by multiplying the estimated number of man-months by a constant factor.
|
6. | What is the problem with different cost estimation models using different measures and cost drivers? |
Discuss |
Answer: (a).It makes mutual comparisons difficult
Explanation:Different models use different measures and cost drivers, making it difficult to compare the results of one model to another.
|
7. | What is one approach used to determine the equations of an algorithmic cost estimation model? |
Discuss |
Answer: (a).Based on the results of experiments
Explanation:One approach to determining the equations of an algorithmic cost estimation model is to base them on the results of experiments, where one variable is varied while others are kept constant.
|
8. | What is a limitation of laboratory experiments used to determine the equations of a cost estimation model? |
Discuss |
Answer: (a).They are not representative of industrial settings
Explanation:Laboratory experiments are often performed at universities with students as subjects and may not be representative of the conditions and professionals encountered in industrial settings.
|
9. | What is the main problem with comparing different cost estimation models? |
Discuss |
Answer: (a).They use different measures and cost drivers
Explanation:Different models use different measures and cost drivers, making it difficult to compare results and draw accurate conclusions.
|
10. | What is the typical approach for determining the equations of an algorithmic cost estimation model? |
Discuss |
Answer: (a).Base equations on results of experiments
Explanation:The approach of determining the equations of an algorithmic cost estimation model is to base them on results of experiments, where one parameter is varied while others are kept constant to determine the influence of that parameter.
