Minimum Viable Product

Correct Answer: Iterate on the MVP with core features focused on personalized travel recommendations and assess the need for a hotel booking feature based on user feedback and metrics.

The correct approach in Scrum and agile product development is to start with a Minimum Viable Product (MVP) that includes core features necessary to meet the primary need of the target audience, in this case, personalized travel recommendations. Including complex or possibly unnecessary features from the beginning, such as AR navigation or a hotel booking feature without validating the need through user feedback, can divert resources from more critical aspects of the product and delay its launch. Comprehensive market analyses are valuable but should not replace user feedback in decision-making for MVP development. Similarly, prematurely focusing on partnerships or integrations for unvalidated features may lead to wastage of effort and resources.

Correct Answer: Crypto buying and selling feature

The essential feature for a new cryptocurrency app's Minimum Viable Product (MVP) should be the core functionality of cryptocurrency 'buying and selling'. This is because the primary purpose of a cryptocurrency application is to enact transactions and trades of digital assets. This is what the users primarily look for. An MVP needs to demonstrate its primary functionality effectively to test their business model and hypotheses. Whereas 'Advanced chart analysis', while useful for experienced traders, it is not a core feature and may extend beyond an MVP's scope, potentially draining resources from core feature refinement. 'Community chat' is not a core feature as well, it's a complementary feature that can enhance user experience but is unnecessary for the functioning of a crypto app. Lastly, 'News update on various cryptocurrencies' is also a complementary feature, not a core feature of a crypto app. Therefore, focusing on the crypto buying and selling feature is the best approach.

Correct Answer: An effective product search and basic transaction functionality

The question asks about the key feature for an eCommerce startup's Minimum Viable Product (MVP). In the early stages of an eCommerce store, the most critical functionality is the ability to find products effectively and complete transactions - hence, the correct answer is 'An effective product search and basic transaction functionality'. Let's examine the other options: 'A complex rating system for products' is not essential for start-up stage MVPs; feedback is important but can be gathered in simpler ways initially. 'Integration with smart home devices for seamless purchases' seems too complex and specific for an initial MVP because the focus should be on proving the business concept, not on integrating with tech gadgets. Finally, 'An extensive backend for vendor handling' may be important down the line, but not for an MVP where the priority is verifying the market need and the basic functionality of the eCommerce site.
