_________ are system development methodologies that propose incremental implementations, respond to rapidly changing requirements, and reduce the emphasis on rigorous requirements. Scrum and extreme programming are both examples of these methodologies. Scrum is a hands-on system consisting of simple steps: The system owner makes a prioritized wish list. The scrum team selects an item toward the top of the wish list and plans the implementation during an event called "sprint." The team completes the list of objectives while assessing progress in daily meetings called scrums. The sprint ends with the system ready to be released. A new sprint starts, using another item on the wish list. This process continues until the prioritized wish list is clear.

In this planning phase, the business typically defines the goals and purposes of new applications or updates to existing applications and briefs Information Technology, or IT, about the plan. In the design phase, architects think about the components they would need to solve the problem or implement the plan. It's akin to looking at a pile of LEGO pieces and deciding which ones you would need to build a model. The design then goes to the programmers who translate it into code to execute the plan during the implementation phase. After the programmers implement the plan, testers validate parts of the code to check if the application is functioning as it should. For example, when you add two and two, do you reliably get four, or do you only sometimes get four? The testers check out normal, day-to-day functions as well as less common things. If the code is unreliable, they try to figure out why. The testers and the programmers work together on iterations and troubleshooting until they develop an application that is workable and stable. During deployment, the application undergoes more testing. For some apps, you release an alpha version for internal testing before going public. Other program

Abigail works as a waitress at a popular local restaurant. When she takes an order from one of her tables, she then types it into the restaurant's computer system. The computer recognizes the menu items that Abigail enters and calculates the cost of the meal. The computer then sends the meal order to the kitchen as a ticket and prints out a bill for Abigail to bring to the table at the end of the meal. Once Abigail's customers have paid the bill, Abigail enters the method of payment into the computer system, which saves the information about the meal and amount paid so that at the end of the evening Abigail's manager can print out a report of how many customers the restaurant served and how much money the restaurant made.Which of the input/output processes is the computer using when it saves the meal and payment information so that the information can be used for future earnings reports.

The Pareto principle is based on the theory that 80% of errors come from 20% of the system, meaning most errors can be identified by testing carefully selected groups of samples. Basis path testing is another software testing methodology. Basis path testing develops a set of test data that ensures each instruction in the software is executed at least once. Techniques based on the Pareto principle and basis path testing rely on knowledge of a system's internal components. This is known as glass-box testing, commonly referred to as ____________ , which includes having developers test internal structures of software. Black-box testing does not rely on the tester's knowledge of the system's structure but is focused on the user experience (UX).

White-box testing
