User Stories

The user’s product journey is divided into several phases. Additionally, if there is any friction along the way, you risk permanently losing the client.

User stories are useful in this situation. They are a crucial component of the agile process and by placing oneself in the user’s position, they aid in understanding their expectations.

From the moment they visit your website for the first time to the point when they become devoted clients—will help you better understand their demands. In order to draw in and keep consumers, you can identify features and solutions for each phase by creating user stories.

Step 1: Searching for Solutions

Users go online for potential solutions to the problems and difficulties they typically face throughout the discovery phase. Additionally, they are contrasting your product with several platforms to see which best suits their requirements. At this point, writing user stories helps you decide which features to include in your product and how to display them online.

User Story: Activities connected with inventory management so I can free up my schedule and concentrate on more important things. I’m an E Commerce business owner.”

As a project manager at a big organization, I need a platform with reporting capabilities and the ability to delegate tasks so I can monitor the development of my remote team more effectively.

I need a payment solution with cheap transaction fees that enables me to charge businesses as a freelancer that works with clients outside of my nation in order to stop losing money on each assignment I finish.

Step 2: Registering & Creating an Account

The user has a few goals and expectations in mind as they prepare to sign up and use your product for the first time, which you must address beforehand. These frequently concern integrations, security, and welcoming users to the platform

User Story: In order to avoid having to manually add all of my products later, as the owner of an E Commerce company, I want to effortlessly connect my store with the inventory management platform after registration.

“As a project manager, I want to invite other team members to this project management platform so they can help me review it and see if it makes them more productive,” the project manager said.

As a freelancer, I would like the option to add two-step verification to the registration process to increase login security and ensure that only I have access to my money and invoices.

Step 3: Purchasing Your Product

There must be no friction involved in the purchase process for users to convert into paying customers. You’ll be left with empty shopping carts and missed opportunities otherwise. These problems are identified in user stories beforehand so that the product experience may address them.

User Story:

In order to know when to make my final decision, I want to be reminded how many days are left in my free trial of the inventory management application as the owner of an e Commerce firm.

“I need a specific price plan because I oversee numerous individuals in several departments at once and have complex needs,” a project manager claims.

As a freelancer, I want to have a variety of payment options (PayPal, credit card, bank transfer, etc.) so I may select the one that works best for me

Step 4: On boarding

Your user retention could be made or broken during the onboarding process. At this point, the objective is to get customers up and running as soon as possible and to point them toward the aspects that are most crucial to them.

User Story:

I want to be able to take a product tour of the inventory management solution as an owner of an eCommerce firm so that I can fully grasp its main advantages.

In order for me to recognize the value that the product has to provide right away, I want to create and assign my first job as soon as I can (within the first 10 minutes).

“As a freelancer, I want to first make a sample invoice to have a sense of what the procedure would be like when billing clients and getting paid.”

Step 5: Retaining Users

The success of your product hinges on keeping clients over the long term. A high retention rate is evidence that your product is addressing the needs of your target market in addition to increasing income.

User Story:

As the owner of an eCommerce company, I need an inventory management system that will enable me to scale, so I can prepare my shop for long-term growth.”

“I want access to a knowledge base with tools like webinars to better understand how my team can make the most of the project management platform,” a project manager says.

“As a freelancer, I want my invoice/payment platform to offer me weekly information on complicated accounting procedures (including budgeting, cash flow, payment safety, and more), so I can gradually learn to handle my invoicing better.”

Step 1: Identify all the entity sets related to your database. The entity sets for an online vegetable supermarket are:

· Website or Mobile Application

· Customer

· Admin

· Product

· Login/ Registration

· Shopping Cart

First of all, we need to start with the Mobile Application or website. This shows that the system is based on the software, and the main bridge between the customer and the store is the website or application.

Step 2: Now, we need to assign attributes to each of these entities like those given below:


Attributes: CustomerID, FirstName, LastName, Address, City, State, Zip, Mobile,Email, LoginID.


Attributes: RoleID, RoleName, Description


Attributes: Vegetable/ProductID, StockID, Name, Type, Description, Weight, Price


Attributes: StockID, StockItems, StockNumber, StockType, Description

Login/ Registration

Attributes: LoginID, RoleID, Username, Password


Attributes: OrderID, CustomerID, OrderDate, ShippingAddress, ShippingCity, ShippingState, Zip, VegetableID, Quantity, TotalPrice.


Attributes: PaymentID, BillID, OrderID, CustomerID, DateofPayment, Amount, PaymentMethod, PayerFirstName, PayerLastName, CardNumber, CardType, Expiry, BankName, AccountNumber, RoutingNumber.


Attributes: BillID, BillNumber, PaymentID, BillReceipt, Description.

Customers will need to register and log in first in order to purchase veggies. They can select the veggies online and put them in the shopping cart. The shopping cart will identify the product and its price immediately. An admin needs to be on the other end, ensuring the transaction goes smooth and there are no possible bugs. The admin can also offer support when needed and add new products or remove any old ones.

Step 3: Identify the key attributes. The key attribute is one specific attribute that uniquely identifies one entity from another in an entity set.

The key attribute for each of these will be:

· Vegetables/Product: Vegetable/Product ID

· Customer: Customer ID

· Login: Login ID

· Roles: Role ID

· Orders: Order ID

· Payment: Payment ID

· Bill: Bill ID
