Expert Solution & Answer
Chapter 15, Problem 15.1E
Explanation of Solution
Technical and non-technical issues:
Technical issues:
- These issues focus on how to reuse the software and how much is it reusable?
- Technical issue is not only related to the reusability to reach its full potential, non-technical factors are also considered.
- These factors are related to organizational and motivational issues like managers may not be willing to compromise with their requirements by allowing the reusable components to be used.
- Sometimes there may be lack of tool support.
Non-technical issues:
- These issues focus on how a project is managed and funded.
- Non-technical issues in reusing the components include high maintenance costs, finding understanding, and adapting the reusable components.
- If the source code of a reusable software system is not available, then there will increase in maintenance cost.

Why is JAVA OOP is really difficult to study?
My daughter is a Girl Scout and it is time for our cookie sales. There are 15 neighbors nearby and she plans to visit every neighbor this evening. There is a 40% likelihood that someone will be home. If someone is home, there is an 85% likelihood that person will make a purchase. If a purchase is made, the revenue generated from the sale follows the Normal distribution with mean $18 and standard deviation $5.
Using @RISK, simulate our door-to-door sales using at least 1000 iterations and report the expected revenue, the maximum revenue, and the average number of purchasers. What is the probability that the revenue will be greater than $120?
