The customer service manager of M&J Chicken has decided to design, develop, and implement an online order taking system to automate the order collection process and to allow customers in accessing their dedicated customer portal and to take online payments.
The purpose of the system is to help the business in automating their order collection process and to make their workflow error-free. It will also help to improve the customer services and to retain customers. Other than that, the system will also help to reduce the staffing cost and staffs will be able to be more productive.
In the existing system, a customer comes in person or calls M&J Chickens to place an order or to inquire. There are six staffs who attends the calls and take orders manually. That is leading to dissatisfaction among the customers, errors in orders, and bad customer services.
The proposed new system is an online web based system. It will automate the order collection, online payment and customer service processes. It will introduce an order form, an inquiry form, and a customer portal. The order form will help to take orders online along with online payment. The inquiry form is there to allow the customers to send queries and the staffs may reply to the queries.

Once the customer makes payment, the order confirmation number will be sent to the customer. The customer can use that for further reference to the order. The customer will provide information about collection or delivery of the order. The staffs will process and prepare the order and then either will keep that for collection or deliver to the customer’s address.
