2. List the user groups and chose the one you’re focusing on
Food delivery app is 3 sides marketplace, so we have 3 main type of users:
Users: Parents and children
Couriers
Restaurants
I’m going to focus on children, who need specific user experience.
I would divide children into next users segments:
0-5 years - too small, don’t have smartphones
6-10 years - some of them has smartphone, almost all the time with guidance.
11-15 years - have smartphones, stay at home alone.
I’m going to focus on 11-15 years group.
3. Describe user flow
Open app - confirm address - choose restaurant - choose food - pay - wait for order - get order
4. List the user needs for your user group
Choose correct street
Eat healthy food
Exclude allergens
Place order
Pay for this order
Don’t be bored while waiting
Safely get this order
5. Prioritize the user needs
I would focus on eating healthy food, because I think it's the most severe problem for children and their parents.

7. Success metrics
I would like to track next funnel:
Number of acquired users - first order - retention - NPS
Clarification and Understanding
The basic functionality of a food delivery app is as follows: User logs onto the app, chooses which restaurant or place they want to order food from, selects items from a menu, and then the food gets delivered directly to the user.
Can we clarify what we mean by kids? I would say a kid is anything from 0 - 12, but even within that range there is a large difference in autonomy between a 5 year old and a 10 year old. For the sake of this problem let's focus on kids aged 8 - 12. They will at least have some basic technical proficiency and be able to comprehend what food delivery means.
What is our main goal with this app? Do we have the luxury of focusing on engagement or should we focus on monetization? Everyone always focuses on engagement, so let's focus on monetization. I am going to approach this question with the context of the US in mind, but if the solution works for other countries as well great.
User Personas
1. Kids - These are the kids themselves who would be using the app. While there is a wide range of ability between kids, we mentioned previously that we were going to focus on 8 - 12 year olds. Will most likely need to have a clean easy to understand and use interface as they are in fact kids.
2. Parents / Guardians - These are the ones responsible for the child using the app and paying for what the child ordered.
3. Restaurants - The people who are preparing the food to be delivered. If the kid centric delivery app has enough traction it might be worth offering an extended kids menu through the app.
4. Delivery Drivers - The people responsible for delivering the food once it has been ordered. These may be 3rd parties or the restaurant's own personell.
With the goal of increasing monetization in mind, let's go ahead and focus on the parent user persona. Ultimately, they will be the ones paying for the food delivery service.
Pain Points / Needs
1. Want to be able to see what their child is ordering
2. Want to be able to control what their child can order
3. Want their child to eat healthy and balanced meals
4. Don't want to overspend on food
5. Want a convenient and easy to use experience
6. Need confirmation that the food has been delivered and the kid has received it
Solutions
Now that we have a better understanding of the different pain points parents face let's go ahead and brainstorm some solutions with increasing monetization as our end goal:
- Meal Subscription service for kids - This would be a weekly subscription service that would deliver pre-selected meals at pre-determined dates and times throughout the week.
- Food Gifting Capability - For special occasions or as a reward, parents could grant their kids permission in the app to order a dessert item. For example, if little Johnnie got an A on his math test his father could grant him a sundae within the app. Upon opening the app Johnnie would see a sparkling congratulations animation and a nice note from his father and then will have the ice cream sundae menu unlocked. Additionally, this could be used as a gift. For example, it is Little Susie's Birthday and Aunt Beckie lives far away but still wants to send her a cupcake she could gift Susie one through the app.
- Group Order - This would a communal app experience for putting together a large delivery order. Instead of having to text or physically go ask everyone what they want from the Chinese Food restaurant you could share a delivery order URL with them and it would open up our delivery app where they could add items to the menu. The parent who started the order would then see everything selected and have final say in what gets ordered. If Susie sees her brother Johnnie asking for a Sunday for dessert she might want one too.
Prioritization
We don't have enough resources to build out all of these solutions in parallel so let's go ahead and prioritize one to focus on while keeping in mind that our focus is on monetization. Let's use the comparison matrix below to help guide our choice:
User Satisfaction, Monetizability, Ease of Implementation
- A,A,B
- B,B,B
- B,C,A
I'm going to suggest we focus our efforts on prioritizing solution #1, the meal subscription service for kids. While this seems like it would be the most difficult to build out it seems like it would have the greatest monetization opportunity.
Solution #3 seems like a nice to have feature, but not necessarily something that users would want to pay extra for. While I could see the Food Gifting app increasing revenue through additional orders, with special occasions only happening once in a while I don't think we would do high enough of a volume to really impact our bottom line. With the sheer volume of food that would be ordered through a subscription service, I think that alone would give us our best shot at increasing revenue. Food delivery is a margin based business so we really need to capture a lot of volume for the numbers to make it worth our while.
Solution Explanation
Let's talk about the solution and why it is appealing to users a little more indepth. I am envisioning the majority of parents using a food delivery service for their children as busy working professionals who don't have the time to cook a proper meal and may not even be home during meal time.
Based off of the presence and popularity of Lean Cuisine's kid focused frozen meals "Kidcuisine" we know there is in fact a market for convenient low effort meals for kids. In recent years there has been a large movement towards eating healthier and organic, which is the opposite of a frozen "Kidcuisine" meal so this tells me there is really an opportunity here. Furthermore, users are used to paying more for convenience as well as paying more for healthy and fresh. If a user wants both convenient and fresh one would assume it would be expensive which is great for us since we are focused on monetization.
In terms of the app itself, the parent would choose a weekly subscription tier which would determine how many meals they want each week and when they want them delivered. Next we would allow the parent to choose which items they wanted their child to eat or we could share a parent approved menu with the child through the app and let them pick out which items they wanted to eat. We would use local restaurants in the area to fullfill the orders and much like today's delivery apps there would be a little map of the delivery driver on their way. After the food has been delivered the child could mark the order as received inside their app which would send a confirmation notification to the parent.
The beauty of this solution both its monetizability as well as its convenience to the user. The busy working parent can schedule this ahead of time at the begining of the month and not have to interrupt their work to order a meal everytime their child needs to be fed.
Random Thought: In order to compete with non-kid specific food delivery services, we could work with restaurants to provide adjustable portion sizes. An eight year old child does not need to eat the same half pound burger that an adult does.
Summary
In order to increase revenue, we are going to focus on the parent user persona and offer them a Meal Subscription Service for Kids. For a weekly fee, parents can choose healthy kid-friendly food items to be delivered at set times to their household.
