Read and understand the Case Study below and create a Data Flow Diagram (DFD) for it.

Topic:

Selecting and Buying Furniture

Scenario:

First, customers initiate their furniture buying process by identifying their needs and preferences. They may consider factors such as the type of furniture, style, size, functionality, and budget.

Once customers have a clear idea of their requirements, they usually engage in information gathering. This involves researching different furniture options, brands, and retailers. Customers often explore various sources, including online platforms, furniture stores, catalogs, and recommendations from friends or family.

After gathering information, customers move on to the selection phase. They compare different furniture options based on their criteria and narrow down their choices to a few preferred items. This may involve visiting physical stores to see the furniture in person, examining the materials and quality, and testing the comfort and functionality.

Once customers have made their selection, the next step is the purchasing process. This involves finalizing the transaction and making the payment. Customers have the option to purchase directly from the store.

After the purchase is made, the furniture is either delivered to the customer’s location or made available for pickup. Delivery arrangements, including scheduling and logistics, are typically coordinated between the customer and the retailer.

Once the furniture is received, customers may proceed with assembly and installation if required. This step involves following the provided instructions or seeking professional assistance if necessary.

Finally, customers evaluate their furniture buying experience. They may provide feedback, testimonies, or share their overall satisfaction with the purchased furniture and the buying process. This feedback can be helpful for other potential customers and can also assist retailers in improving their products and services.

Explanation of the DFD:

The process starts with the customer identifying their needs and preferences.
The customer then moves to the “Gather Information” process, where they research various furniture options, brands, and retailers.
After gathering information, the customer proceeds to the “Select Furniture” process, where they compare options and narrow down their choices.
Once the selection is made, the customer moves to the “Purchase Furniture” process. The interaction between the customer and the retailer takes place here, where the transaction is finalized and the payment is made.
After the purchase, the retailer coordinates the “Delivery” process with the customer to schedule and deliver the furniture.
Once the furniture is received, the customer can proceed with the “Assembly” process, either by following provided instructions or seeking professional assistance if needed.
Finally, the customer provides feedback in the “Evaluation” process, which can be useful for other customers and help retailers improve their products and services.
Please note that this is a simplified representation of the data flow and doesn’t capture all the specific details or interactions that may occur in each process.
