Consider an online shopping portal that allows a customer to browse and purchase different products. The products are arranged under different categories like Books, Computers, and Electronics, etc. Only a registered customer can order a product from this portal. Each registered customer will have his own shopping cart. He can view, add or remove products in his shopping cart and view his total bill. The final cart is submitted for payment and details like shipment address are confirmed by the customer. The customer is confirmed with a shipment id and delivery of goods within 15 days. Once the customer finishes selecting the product/s, he can view the cart and then place the order by providing details like postal address, number of items, etc. The website is managed by an Administrator. An administrator can add, remove and update categories, products under each category, their price, and quantity. He can also remove or verify the customer. The project manager of the system adopted the scrum process model to divide tasks into small iterations with cross functional communication amongst teams. The project manager fails to manage the reliability of the system due to improper validation and stakeholder involvement/feedback. Thus, an integrated scrum process is required to improve the development process of a given scenario. You have to give reasons why scrum not successful in this scenario and which process method best suitable for this type of system development with a combination of scrum process.
