The idea of smart refrigerator will be really helpful like Amazon cart, where the items which you put can be scanned and like Samsung smart refrigerator it will have a UI to show the list.
I would add to what Prerana and Swasesh Kumar said, I would also have AI build that detects the freshness of the food and gives an alert when its time to remove the food from the fridge so that it doesn't get spoilt/ rotten inside. Those notification would be sent to user over the app directly. Also I'd want to keep the fridge temperature and compartments customisable and adjustable, dividable into different zone as per the needs by the user through the app. So that the person on a wheelchair could adjust it as per the needs and requirements.
I think being a disabled person , the major pain point of a user would be accessing the refrigerator be it like opening the refrigerator , accessing the vegetables or putting the vegetables or stuff back into the fridge after your purchase. All of these pain points can be solved by a smart refrigerator operated via a mobile app or Alexa or voice assistance where a user can give a command like open the fridge or open the container to get his vegetables or put it back. Rest all solution can be considered like screen scanner , integration with Amzaon Groceries etc after we launch the product. I would measure the success of this refrigerator via offline sales & return & adoption via mobile app where I can track telemetry usage of the person on the app while accessing the refrigerator
This video taught me a lot of things. Understanding problem, creating use cases, prioritizing use cases for a MVP, creating Solutions, prioritizing Solutions, etc. I would like to call this video as "Product Management First step". One must watch this video if they are new to the Journey of becoming a PM. Thank you Diego and to the interviewee!
Your channel is super underrated! I really enjoyed the incorporation of advertisement to the fridge at the end. Other feature solutions could be maybe a remote control or a voice control to open and close the fridge door seamlessly. Another edge case pain point could be: - An user in a wheelchair may be more susceptible to accidents occurring, maybe glass containers falling from the fridge if mishandled
Thank you Daniel! 🙏 Please consider sharing my channel so that it reaches many others! Thanks for these suggestions! How would you solve the edge case pain-point?
@@PMDiegoGranados Thinking about this problem, I think another edge-case pain point could be how it may be difficult for a wheel chair user to reach the taller heights of a normal fridge. In an attempt to tackle both pain points, I would suggest a low-level fridge. The highest counter of the fridge should be reachable for the wheel chair user sitting down. With a low-level fridge, 1) accidents are more avoidable and 2) wheel chair user has more agency in picking items from all spaces within the fridge However, I would include some tradeoffs such as a low-level fridge may take up more surface area while having less storage space as well. If the end goal is to design a fridge for wheelchair users, this design may still be worth it! Would love to hear your thoughts or feedback on this design!
@@danielkim254 I feel, We can have a robotic arm that is integrated with voice control. Now every time you want to take something out just mention its position to the arm (like 2nd compartment and 3rd bowl) which will take the product out and plat it on a plate which will be part of the fridge. Now the wheelchair-bound person can simply take the item and again voice command the fridge to close itself. This would reduce those dangerous cases where accidents might occur, but its implementation will definitely be difficult. Please correct me if I am wrong.
Your videos are so helpful, esp for someone who wants to break into PM. I watched a lot of mock videos on other channels and eventho they are very good, I was like “Gosh this is not for me. how am I going to think on the feet like this?” Landing here, your way of structuring the framework and repeatedly analyze them as candidates present their answers help so much. I have slowly found myself overcome that fear of saying some wrong or worthless solutions. Could you please do mock videos or talk about your framework for breaking down estimation questions and technical questions (like “why gmail search is slower than google search”?) too?
IMHO the interviewee was trying to show off all the theoretical knowledge he has. Yes, he has good understanding about the discussed PM subjects, but another valuable skill is to know what tools to use and to what extent. Nevertheless, thanks for the great content! I am learning something new with every video I watch
My moonshot idea: This is a very interesting use case. Leverage IOT, NLP and A.I. A.I.: 1. Use camera inside the fridge to identify the object and create directory of products in the fridge. 2. ML model can be used to predict product/produce expiration or near expiration IOT: These days IOT enabled fridge are readily available, so we can make use of that to fetch product directory (contents in the fridge) and display it over mobile device or fridge screen NLP: 1. Natural language processing has seen exponential improvements. It will be very convenient to send voice signals to the IOT enabled fridge. 2. In the MVP phase it can be as simple as providing voice instruction of what needs to be fetched from the fridge and item will dispense out. This will take care of the tough to reach spots (too High or too Low or too far back) pain point. Roadmap post MVP: User journey doesn't end with fetching the needed items but it extends into washing, cutting etc. A person in wheel chair will also be challenged in performing these tasks. Future phases are being recommended with consideration to these key user journey steps: 1. Inbuilt produce washing machine. This feature can potentially save a lot of water wastage. Also machine based power cleaning can work better than cleaning under tap water. 2. Fridge can have a peeling and cutting chamber. 3. Alert to replenish low stock items 4. Integration with external sources to alert about recall 5. Nutrition info display At just a push of button or voice command over phone, fridge can fetch, wash and peel, cut, chop produce and deliver in a ready to use state. Recall notification features will also help user to avoid consuming produce or products that are riskier to consume. I love this use case and there are endless possibilities (Cross-sell, Upsell, Optimal space utilization etc.) While the idea is being discussed for people on wheel chair but can be easily extended to all users and increase the TAM size.
LOVE THIS! Thanks for such a detailed answer @Harshad! Follow-up question for you about the MVP: Say that you have both the AI & NLP implementations in this Fridge - how would you measure that it was successful? In other words, what metrics will you use to measure success?
@@PMDiegoGranados For the MVP implementation leveraging AI and NLP, here are the two KPIs that I would like to measure to assess the product success: 1. Track how many times user was able to complete the journey without having to open the refrigerator. This would be a good indicator on couple of fronts a. Accuracy of tech stack in place (Voice command recognition, A.I. image processing, Dispenser functioning) b. Customer journey satisfactory completion To be able to track this metrics we can leverage IOT to sense device proximity and Sensors to understand user proximity and user action (opening the fridge) and drawing conclusions off it. 2. Number of commands sent to the fridge. This metric would give insights into the usefulness or utility of the product to the user. This metric should be looked at in conjunction with voice command recognition accuracy as high volume of command due to inaccurate recognition could lead to false positive signals. While suggesting above KPIs I took guidance from the suggestions you made, regarding how to propose metrics, in your "Product Manager Interview: Design Facebook Travel" interview. Thanks :)
Would I be wrong to say that simplicity in design is the best solution here? While I see alot of people mentioning all the fascinating tech available on the market today as a solution to the issue of reach for the disabled person, I am just here wondering... why not make the fridge low (like bed side height) with two-side doors so the user can easily access the fridge then increase the width to accommodate more compartments etc. Not only will this solve the primary problem, it will also keep the cost reasonably low so that more people being targeted can afford it. @Diego, I am really keen on knowing what you think regarding this simple solution.
Hi Diego,another gem of an interview.kudos to what you are doing,I am getting more interested in product management as a subject to dwelve deeper. If you ask me how i would approach, I would look at it in terms of affordability and reach for the product , revolve ,rotate and replace for design. As I am a start up I want to create a design which is cheaper and can replace the existing design like a chassis.i would borrow from automobile industry, chassis remains the same but the design is different. So, for bottom of pyramid market(at least in the Indian context) which has huge number of consumers , affordability matters. A fridges outer design is same, the cooling method is same, but I would create a replaceable internal design which can be patented and outsourced to existing fridge manufacturers. A simple way to solve accessibility of material inside a fridge is the revolve and rotate, which means imagine a cylindrical Design with grooves where vegetables can be kept,user opens the fridge and rotates the cylinder to access the vegetable she wants. The same thing can be used for accessing the top and bottom case in the fridge. Also remember that affordability is very important as usually people with disability would have lower incomes(just using logic as mostly they would be aged and retired, I do not have data) and once I am done with design then self ordering, iot can be done as versions of the basic fridge. I can go on, but thanks for igniting my mind.
Great content Diego! I especially love the onscreen thoughts. One thing I'd like to do is to ask interviewees to self reflect before providing feedback. Another thing I'm always wondering when viewing mocks on RUclips and would love an answer is whether this interview is above the bar. Maybe for those interviews where the faces are hidden, it would be very interesting to know, beyond the feedback, if this was "good enough" or amazing
Thank you so much for your comment, Chen! And thank you for the suggestions!! While I’ve thought about them too, here’s why I don’t show them in the video: I always ask the interviewees to self-reflect but I don’t publish that part of the video. Someone could feel bad if the difference between their self evaluation and the comments I share are too big or not what they expected. Ultimately, throughout the interview I want to make sure they feel comfortable in the process and in the outcome. And about the “above or below” a bar - it’s a tough one... The bar is very subjective and will depend on each interviewer and company. My own personal opinion on an interview like this doesn’t represent Microsoft or any other company, so it’s hard to say a definite yes or a definite no. If you have any other feedback or suggestions they are always welcome! I’m happy to share these thoughts to make the process transparent for everyone 😊 thank you for your suggestions!
How can we apply for a mock interview with you? I’m getting ready to apply for an internship, and I would really appreciate this experience, since I don’t have anyone else in my proximity to practice with.
What do you think about the solutions? What is your moonshot idea?
