Let’s understand how to answer these questions in detail.
Q Form — Design: How would you design a <product>?
What approach to take:
Step 1: Identify the users and customers who’d be using the product. Understand the well.
For example, if you are asked to design mobile app for an e-commerce seller.
Get deep into understanding your users –
Ask about what do these sellers sell?
Do the sellers sell on multiple channels?
Are the seller’s individual or enterprise sellers?
For Step 2 to 3, it would be helpful to develop a customer journey map.
Refer: PM101 – Chp 4 – How to Create Personas & User Journey Mapping?
Step 2: Understand the use-case. What are the goals of your users or customers in each phase of using the product?
Step 3: Are the users using any current product? What are the challenges faced in the current flow or by using the current product?
Step 4: What improvements would lead to a better experience for your users or customers based on their goals?
Step 5: Visualize (if possible) the design based on identified improvements.
Q Form — Improve: What would you improve about <product>?
Step 1: Understand the User and their goal.
Step 2: Understand the Product Goal.
Step 3: What are the problems that the product face currently? This can be related to product flow, lower user engagement, increasing revenue or conversions, etc.
Step 4: Brainstorm on how you can improve the product. The improvements can be bold and big as well as small and iterative. You could use –
a – Customer Journey Mapping as shown to brainstorm improvements around the current challenge
b – Focus on Usability of the product to come up with improvements
Step 5: How would you implement these improvements? Are there any technical or business constraints that you should discuss?
Step 6: How would you validate your improvements? What metrics would you track for validation?
You are asked how to improve Go-Fro website — a holiday package booking site. You could develop a customer journey which would help you answer.

Step 3: How does the product solve the problems? Or How does it accomplish the user goals?
Step 4: What is great about the product — in terms of Usability? What are the “Wow” features?
Step 5: How does it compare with other alternatives?
Example — Trello is a visual system to organize anything (Projects/Ideas/Personal Tasks) the way you want. It is a super powerful tool to make project management easy, collaborative and even fun. Let’s explore how you can use Customer Journey Mapping to answer a question on a favorite product (Trello).
– Visual Appeal where user can visually see tasks rather than simple texts
– Intuitive and ease of use
– Conceptually Easy
– Flexibility to use Trello as a Project Management Tool, Week Planner, Travel Itinerary Planner, Ideas Management Tool or simply day planner
You could also rate Trello in terms of usability (using screenshots) –
Learnability — The product is pretty easy to use for any first-time user
Efficiency — User can accomplish their tasks/goals with ease and in less time
Recovery from Error — User can easily undo any changes that they make (e.g. moving a card back, or deleting any task)
Satisfaction — Going by reviews the users are pretty satisfied by Trello
Q Form — Question on Product/Business Strategy
You should think about a Product Strategy on Micro (Product) level and Macro (How Product fits into Business Strategy) level.
– Why did MakeMyTrip and Goibibo merge?
– Why did Amazon enter into India via Junglee and why would it suspend it later?
– Why Microsoft bought LinkedIn?
– Why Flipkart bought Myntra?
– Why would Google be interested in entering into cell phone market?
– Why did Google stop shipping Google Glasses?
– Why would Facebook buy Whatsapp? What could be the possible ways to monetize Whatsapp?
You could think of following strategies which can help you answer the questions –
- Increase addressable market
- Synergize products to provide more value to users and complete workflow solution
- Entering into new market
- Reducing reliance on a Key Partner
- Bringing a core competency in-house
- Being a “One Stop for — ”

Workflows for Product Synergy
Example Why Microsoft bought LinkedIn?
Microsoft has been moving from just being a productivity tool to offering a whole range of cloud service (especially for enterprises). LinkedIn brings the power of professional network which can really help Microsoft provide a differentiated cloud offering which can re-invent business processes in a whole new way.
This synergy can bring together a professional’s information on LinkedIn’s public network with the information in Office 365 and Dynamics to provide a more connected and intelligent productivity flow.
Also, it would drive better monetization through more targeted advertising.
Remember, Microsoft knows what you are working and with whom (Office 365) and what kind of people (LinkedIn network) and what information (LinkedIn news feed and Lynda) can be helpful to you.
And combine all this with Cortana!
Q Form — Metrics: What metrics would you track for a <product>?
Step 1 — What are the business goals?
Step 2 — Identifying business metrics based on business goals e.g. CAC, LTV, MRR.
Step 3 — Identifying any North Star Metric and/or Check Metric.
Step 4 — Identifying Product metrics based on Business metrics
The two approach to defining product metrics are –
– You are launching a major change in UI of your company’s app. What metrics would you track and why?
– You are a founder of SaaS startup and have just raised capital. Your investor has asked you to develop a company health dashboard. What metrics would you choose to display on that dashboard?
Q Form — Launch: How would you launch a <product>?
Important framework to use –
