Requirements spec

Requirements Specification for a Web based Bill Payment facility which allows your Case Study Company, GasEl’s domestic customers to view their utility bill on-line and to pay by Credit or Debit Card. Currently GasEl does not provide such a facility and this is causing operational problems with many customers contacting the Service Centre to pay bills by card over the phone or by posting in cheques. This is absorbing valuable resources which could otherwise be applied to more productive, revenue generating activities. The Auditors have also recommended that the current practice of accepting card payments and cheques needs to be reviewed and controls strengthened. You should specify a Web based facility to allow domestic customers to view their utility bill on-line and to pay by Credit or Debit card. You should specify the requirements for the Website facility as follows:- Short introduction to site- Use Case Diagram - Initial list of requirements- Wireframes for key screens on Website- Functional Modules describing clusters of functionality- Detailed functional requirements describing what users can do- Detailed non-functional requirements describing how the Website should perform.- Prioritisation of non-functional requirements using MoSCoW criteria.You may produce wireframes using PowerPoint or research wireframing tools if you wish. A popular tool with some participants is Balsamiq (www.balsamiq.com), which has a short trial use period; and there is also a free tool from www.justinmind.com/prototyper/free-edition
