Case study 1: Develop a payment module for ecommerce platform Objective: Prepare a project charter for developing a payment module for ecommerce platform. Background: CEO of the grocery chain has determined to commence the digital shopping experience. She is confident digital shopping will open up new revenue stream but skeptical whether the company can truly launch the full scale solution. To prove her in house team can actually deliver the target state, she has hired you (students) as project manager to carry out a Proof of Concept (POC) to develop the payment module for ecommerce platform. The system will support both mobile phone and web registration. The system will require users to provide customer information such as first name, last name, email address, phone number, billing and shipping addresses, and partial credit card details. Identify and include any appropriate security measurements. No POS and inventory system integration at this point. Submission requirements: Prepare a project charter for the Proof of Concept (POC). Can you give me initial total budget just to develop a payment module (both web and mobile responsive) for ecommerce platform which is already running??
