Have a look at this diagram of a quality attribute scenario:

Q4 - is a condition that will cause the system to respond. What is this called?

• perturbation

• request

• error

• stimulus

Let's look at the same diagram of a quality attribute scenario:

[Q5] is the part of the system affected by the stimulus. What is this called?

• artifact

• context

• process

• component

Which of these could be considered under the environment in a quality attribute scenario?

• Send error to external system

• Internal subsystems

• Unrecognized system request

• Recovering from error

• Evaluation team, outsiders, project team

• Clients, designers, stakeholders

• Peers, outsiders, designers

• Evaluation team, project decision-makers, architecture stakeholders.

Leon is analyzing the architecture and notices that under conditions of high numbers of users signing on at the same time, there is a potential that one of the architecturally significant requirements (ASRs) will not be met. What is this called?

• Utility shortfall

• Risk scenario

• Tradeoff

• Non-risk scenario

Maddie's software team is split into two subteams working on two different components that work together. These teams share one large room and are in constant contact. According to Conway's Law, what could happen if Maddie does not physically separate the two subteams?

• The components they produce will be very tightly coupled.

• They will not leave sufficient comments, thinking that the other team already knows the relevant details

• Their components will repeat code unnecessarily

• The component interfaces will not be reusable

This is one of the styles of implementing variations. What is it called?

• replacement

• composition

• composition
