Shop on your own pace, with the self Checkout- UI/UX Case study | by Ashokkumar Balasubramaniam | Nov, 2021


Now that I have insights organized into user sets, to connect more with the user sets and use them as a reference across the project, create well defined user personas based on the user sets

After all the research is done I have to validate the hypothesis with my research and scope it down to which hypothesis was validated and which was not validated in order to proceed with ideation stage

Hypothesis Statement 1

This hypothesis was validated by my research

In my brainstorming session, I got this hypothesis statement where the user can scan the product and the item will be updated in the virtual cart in the app itself though this process has not been implemented anywhere some of the features have been implemented where the user can grab few items like nearly 10 items and take them to the self-checkout counter and bill them all by themselves

Validation through research

In my secondary research, I have this insight where the user can use a bar code scanner to scan the item they want to buy “just as barcode technology transformed the efficiency of retail stores in the early 1980s”

Hypothesis Statement 2

This hypothesis was validated by my research

In my primary research, I have got a lot of insights about the user using a pre planned list for the items they need to shop and shop. According to that so that they don’t miss anything and have to come back to get that particular item to avoid this they use a shopping list

Validation through research

My user would like to have a preplanned shopping list within the app so that they need not write it down and carry it with them and some of my users uses the notes feature in the mobile to write down the list. I suggested the idea of having a shopping list to note this within the app and they supported this feature

Hypothesis Statement 3

This hypothesis was validated by my research

In my brainstorming section, I got this idea to make the self-checkout process at its maximum because if the user is waiting for a long time to make the payment alone the self-checkout process is not useful to the user so I had this hypothesis about making the payment online within the app means it will be useful for the user to checkout easily

Validation through research

In my secondary research, I got an insight that validates this theory which is

“More consumers are armed with smartphones, and the number of people who use mobile payment methods is also on the rise. In fact, it’s expected to be used by 56% of the consumer population in 2020, according to Mobile Payments World

Hypothesis Statement 4

This hypothesis was validated by my research

In my primary research, I had this insight from my user for how they are facing this issue of packing once they are done shopping, from the insights I came up with an idea for this packaging problem

Validation through research

In my primary research users are more likely to get their items packed and wants them to be dropped off in the car or delivered in their home

These hypotheses are not validated by the research or these are not in priority to be solved in this problem statement. maybe it can be solved in the future updates

Scoping down the hypothesis that needs to be solved in priority:

  • My hypothesis is that the user can scan and update their items in the virtual cart
  • My hypothesis the user needs to track their items during the shopping on which they already planned to shop as a shopping list
  • My hypothesis is that the user needs to make the payment easily because making payment for all the items can be a hassle
  • My hypothesis is that packing all these items. So let the staff pack the items

Original: Natures Basket wants to introduce a product that will allow the self-checkout process in its physical stores. This will help with the long lines and will help avoid contact. They will still have people to monitor and be present in case of any assistance.

Reframed:

Nature basket found that the number of people shops in their physical store has been reduced because of the crowd in the check out section. So introduces a self-checkout process to increase the shopping rate

  • Implementing a self-checkout process
  • Making the payment easy in this self-checkout process
  • Making the packing better to give a good user experience

The reason for scoping down the problem statement:

The reason for scoping down the problem statement is because there are problems faced by the user while implementing this self-checkout process and considering the user spends a lot of unwanted time .. so reducing it efficiently to give a better user experience

Solution 1:

Scan your product and it will be updated in your virtual cart

how it might work

The user needs to scan the item with a barcode scanner that was given to them and automatically it will update in your shopping cart

Problem solved:

To make this self-checkout process .. the user should have control of what they are shopping so the idea is to give them a bar code scanner, the bar code scanner has a QR code stuck on the scanner so that the user can scan with the phone camera and update it in the app

Insights from the research:

In my desk research, I just got this insight about giving a bar code scanner to the customer and letting the user scan whatever they shop.

“Just as barcode technology transformed the efficiency of retail stores in the early 1980s”

And I asked this idea to my users and most of them said it will be helpful to them

User 1:

It’s a nice idea to give the bar code scanner.

User 2:

I feel this will help me and save my time.

Solution 2:

A shopping list within the app

How it might work

A feature that allows the user to make a list of the items which they want to shop for when they enter the supermarket and also when they scan this item in the barcode it also gets striked out it will help the user to keep track of the items

Problem solved:

In my primary research, the users are preparing a list before going shopping most of them are writing in a paper and using a notes app to write down on the mobile phone so to solve this problem. I’m introducing this feature so that the user doesn’t need to switch between apps or carry the paper along with them all the time.

Insights from the research:

User 1: I prepare a list in the Samsung notes app before going to shop so that I don’t need to think about the items which I want to shop and forgetting things causes problems “I have to come back or go to a nearby grocery store to get that particular item which I missed while shopping

Solution 3:

Making a payment online after they finish shopping using this self-checkout process

How it might work

Making a payment online could be easy when implementing a self-checkout process because the items will be scanned and updated in their apps virtual cart making payment in cash could be a problem

Problem solved:

In my primary research, I got insights that users want to make it as contact-less as possible so making the payment could also be done online to avoid the hassle

Insights from the research:

In my desk research, I got the insight of people to prefer paying digitally

More consumers are armed with smartphones, and the number of people who use mobile payment methods is also on the rise. In fact, it’s expected to be used by 56% of the consumer population in 2020, according to Mobile Payments World

Solution 4:

Packing the things that the user has shopped without making them spend time on it

How it might work

Packing things could be a big problem for the user especially for the thing they shop for once in a month or two so .. my solution is to leave the shopping cart in a place and get it packed until that the user can have a cold coffee or something and collect their items packed at a pickup point or something.

Problem solved:

The packing takes time because the items will be lots because we are getting it for 2 months of groceries and they have to keep the edibles and the other groceries separate for the soap, detergent, etc. so it takes time and they will come and keep it in the car.

My solution: My solution is to leave the shopping cart in a place and get it packed until that the user can have a cold coffee or something, the app will intimate the user that their items are packed and tells the estimated time when to collect their items packed in a pickup point or something

Insights from the research:

Each of my users expects the packed item to be dropped in their car or to be delivered to their house.

After ideating the solution for the problem statement. I have made a user flow draft. This helps me keep on track when designing the wireframes
