Understanding the Users

I conducted the user interview with 8 bakers to gain insight into their passion and pain points.

{ Pain Points }



Specific products sometimes missing, so uses substitutes, but this results in unpredictable results.



Unable to finish ingredients and they are difficult to keep fresh.



Lack of confidence to prepare food at home, or don’t know how to cook a dish without a recipe.



Working adults are too busy to spend time on meal prep.


Users thoroughly enjoy the baking process, but they often feel uncomfortable when dealing with unfamiliar ingredients or recipes for the first time. Additionally, many people find it challenging to allocate time for shopping or baking.

{ Personas }

Created by conducting user research and identifying common pain points, which are UX issues that frustrate and block the user from getting what they need from a product.

Problem Statement

Molly is a busy marketing intern, who needs a more effective way to buy ingredients at one time because some products usually out of stock, it isn’t good use of her time.

Going Forward

{ Next Steps }

Create for other pages. In addition, add more details like motion and interaction settings to make this app more practical and easy to use.

Conduct another round of usability studies to validate whether the pain points users experienced have been effectively addressed.

Conduct further user research to identify potential new areas of need. This could involve interviewing bakery shop owners to gather their perspectives and insights.

{ Takeaways }


The app makes clear that it cares about fulfilling user needs.

The quote from users‘ feedback:
“It was very intuitive and straightforward without taking me on unnecessary detours.  I would absolutely use this app to purchase my daily ingredients.”


While designing the HomeBaker app, I learned that the first ideas might not be the best ones.  Usability studies and peer feedback influenced each iteration of the design choices so I could make the right design choice to improve the product.
