9. Observation:
Most interviewees were environmentally aware of food
waste.
Insight and Learnings:
Most already purchased groceries online and would do so
for outgoing food if the food came from reliable merchants
that were convenient. Some stated that it would depend on
the type of food (e.g. bread or pasta instead of dairy or
seafood products)
Conclusion:
A marketplace app that is easy to use and would provide
a wide range of outgoing food and groceries that is
conveniently located near our users
Next Steps:
Empathy map input will be used to develop persona
motivations, goals and needs

10. How might we provide better access to a wider variety of food
and groceries
For green aware and budget conscious consumers
So that they can easily find and purchase excess food, near
expiry groceries and contribute to the reduction of food waste

12. Green Gabriella reads and finds out about food waste in
her city and wants to do her part in her family life.
She is working late and is hungry.
It's 9pm and food options are limited.
As reducing food waste is top of her
mind, she whips out her phone to check
the Food Angel app and sees a range of
restaurants with good quality outgoing
food that restaurants need to sell by end
of day. She decides on a bento set for
dinner.
She finds a warm hearty meal at a
discount, near her, at a time most
restaurants were closing

13. Bob, a bakery owner, realizes that he has
excess donuts and that many will be unsold.
He uses the Food Angel app to update his
sales items for today on the app, offering a
whopping discount to customers. While
surfing the app, Green Gabriella finds the
offer and decides to also get donuts for
breakfast.
While on the platform, she also finds out
that her neighbourhood supermarket is
currently stocking outgoing fruit and
vegetable items that she needs.
She puts in an order in for a bento set,
5 pieces of donuts and a vege box at an
amazing discount. She makes payment
through the Food Angel app and receives
an instant confirmation immediately.

Green Gabriella feels she has contributed to
the reduction of food waste, saved some
money and feels great doing it.

16. Problem Statement
There is a general lack of access (both in ability to buy and awareness) for everyday
consumers to buy excess/outgoing food from restaurants, cafes, hotels, bakeries and
grocery stores.
Wastage of food and grocery products in Singapore are significant and there is great
opportunity to reduce food waste and improve Singapore’s environmental footprint.
Hypothesis
We believe that consumers in Singapore will use an app (marketplace) to buy outgoing
food and grocery items because it provides ease of access to a variety of outgoing
food items near them, at a reduced retail price and contribute positively to reducing
food wastage.
Test
A wireframe was created, additional first-time landing information was included to
accelerate learning curve about the unique selling point about the app.
