Anubhav A. - "Clarifying question: Do we want to judge need of an existing product or an idea that can be converted into a product Let me solve for both the cases. Q: Determine if there is a need for a platform that is already live and has some users. While thinking about need, I am finding it resonating with "Does this product have a pmf". Few ways to do that: Take a look at the retention number (D1, D3, D7 and D15). Basis on the product the time range can be different but if the retention number is"See full answer

ready4new - "I will need to understand What are we selling and who is the target customer? Is one retail location per metro area enough or is the market big enough for multiple stores? What is the goal of future retail locations? Gauge the market for fit or drive revenue.

If LA market is not large enough, then my second store will be in an a different"See full answer

Harsh S. - "Some clarifying questions. Does this include storage required for backup? Assume - Yes and only one replica. Will email be compressed? Assume - Yes Assuming world wide user base. Let's formulate the equation required to estimate this answer. total storage required = (Total users x storage growth/per user + new users x storage required/user - all users x delete storage)*compression ratio + storage required for one replica. Total Gmail users = ~1B Based on my own ema"See full answer

Katherine B. - "We want to use rigorous framework for evaluating shipping a new feature — ideally an A/B test. If an A/B test is not available, we first evaluate quantitative data; we look at feature adoption metrics, time-to-use, retention and frequency of visitation. What does the business impact of the feature on conversion rates, revenue per users and LTV, and secondarily evaluate any error rates that could be occurring after the launch of the new feature. It’s important for this analysis to perform segmen"See full answer

Rajeev K. - "At Kabuk Style, I found myself managing two major initiatives at the same time both of which had high visibility and were critical to the business.

Scott S. - "As engineering managers, it’s our obligation to prioritize and manage technical debt properly. However, achieving the correct mix between reducing technical debt and providing new features while meeting deadlines can be fairly tough.To manage technical debt efficiently, it’s vital to first understand how to detect it inside your projects. One way to do this is by doing regular code reviews and encouraging your team to share any concerns or areas where they feel the codebase may be improved. This"See full answer

Bhavana J. - "First let me try to understand the metric: when you say traffic to facebook marketplaces, you mean that number of people clicking on the marketplace tab or landing on the marketplace section has reduced. Am I right? Ok, here's my approach: I will first try to narrow down the scope of the problem by understanding what the details associated with the drop. Then I will try to hypothesize on what all could have caused it. Finally I will try to propose a solution basis the findings. Understanding th"See full answer

Adib M. - "Ask if the quality aspect is negotiable? Clearly hoping it is not. Then move on to explain nicely about the iron triangle - scope, time, resources. With scope and resources fixed, the time would need to be variable unless the project is considered cookie cutter, the exact project has been done many times in the past. (which is unlikely). If time cannot be relaxed, then the scope should be variable."See full answer
