Agile Modeling (AM)

Correct Answer: Set up a model storming session to debate and determine the appropriate technology stack to use.

Model storming is a technique used in Agile development projects to bring together the team to tackle a particular challenging aspect of the project. It involves intense brainstorming and discussions to come up with a solution. In the scenarios presented, the best use of Model Storming would be in setting up a session where the development team can debate and determine the appropriate technology stack to use. Letting each team member choose their own technology stack may lead to a lack of coherence and compatibility issues within the project. Also, using the same technology stack used in the previous project without consideration does not account for the unique requirements and characteristics of the new project. Additionally, asking the client to select the technology stack may not be the best approach as the client may not have the technical expertise to make an informed decision. Therefore, setting up a model storming session for the team to collectively deliberate and choose the suitable technology stack is the ideal approach.

Correct Answer: Review and simplify the test to ensure its functionality is well-understood before attempting to write the code.

In the Test-Driven Development(TDD) methodology, the 'Red-Green-Refactor' rule is executed. According to this rule, when a test fails('Red'), the developer's next step should be to write minimal code to pass the test('Green'), and after making the test pass, the code should be improved without affecting the behavior ('Refactor'). Thus, the best course of action when a test case is failing is to understand why it's failing and make it pass. Reviewing and simplifying the test can help in achieving this. The other answers are incorrect because ignoring the failing test and writing code for the new feature in test-driven development is not a good practice. The essence of TDD is to identify mistakes and issues during the development phase. Attempting to write complex tests until one test randomly passes could lead to more issues or bugs in the code. Lastly, the developer should not check with the project manager to decide the next course of action. The developer is expected to understand the failing test and handle the issue independently.

Correct Answer: Create a joint Architectural Model defining each service component

The best approach in Model Storming for the team to apply would be to create a joint Architectural Model defining each service component. This is because Model Storming, a method used in Agile Modeling, is an approach where the team collaboratively brainstorm and sketch a model on a just-in-time basis. As they are building a new search engine functionality and are unsure about the architecture, creating a joint Architectural Model would help in visualizing and defining each service component, thus ensuring everyone in the team has a clear understanding of the architecture. Meanwhile, performing waterfall project management is a sequential design process, and is not related to Model Storming. Using a blackboard method is a shared knowledge base approach, which again does not align with Model Storming. Lastly, adopting a traditional brainstorming session is a general method and doesn't provide the structure needed for designing a search engine functionality's architecture.
