current Coursework Regulations, including details of penalties for late submission, procedures for Extenuating Circumstances, and penalties for Assessment Offences COMP1821 Coursework Specification This is a group coursework A Group consists of to students You can only form groups with students within your tutorial group Please include in the appendix a short personal discussion regarding your role and contribution within the group Every member of the cw team should attempt every single task of the cw and document their work The purpose of the CW Team is to discuss each of member’s solution then choose the best one (these may be a combination of solutions from different member’s) Other team members’ poor/non contribution cannot be used as a justification for extenuating circumstances The coursework tasks should not be split among the members, as most likely this will result to poor overall work The grades are individual, based on each team member’s contribution to the tasks as shown in the task pro-forma (see the deliverables for more detail) You are expected to submit one output -your group’s final report Each member of the group should upload – one PDF file that contains the group’s final report You are also required to a presentation of your proposed system design and demonstrate the prototype to your tutor Case study: MobilesForAll.com LTD MobilesForAll.com LTD is a medium-size chain company spread across the UK that specialises in selling affordable mobile, tablet and broadband deals Customers can locate the company by recommendations from others, advertisement in newspapers and magazines, by visiting the shops in person or by visiting its online website Its customer base consists of adults with ages ranging from 16 – 65 The company has an automated Customer Relationship Management (CRM) system which allows Customer Sales Representatives (CSR) to manage the subscriptions At present, most orders arrive by phone, or in person, although the company’s website has been live for a few years now and these are handled by the CSR The CSR will discuss the new packages and deals and they may also suggest alternative packages based on specific preferences provided by the customer They can also provide customised deals, based on the customers’ requests If this is the first time that a customer has requested a specific subscription with the company, then a customer record is set up by the CSR As of late, senior management are very concerned by the decline in subscriptions over the past few years and this is due to increased competition In order to succeed and maintain its place in the market, management believe that they need to be innovative and provide a better customer experience Currently, there is no real-time assistance on their online portal and the company’s customers often experience significant lag-time between purchasing a package and receiving e-mail confirmations and/or a statement in the post When customers call to amend their subscriptions or make any other enquiries, they have to wait an average of 10-15 minutes before they are put through to a CSR and this is mostly because there are not enough staff to handle the calls In a recent customer satisfaction survey, 68% of customers did not feel that the CSRs had enough information to fully understand the customer’s issues and needs In order to provide a richer and faster customer experience, the company plans to develop a mobile application for recent operating systems such as (Android 4.4 KitKat) which will be supporting and enhancing their already existing online presence The app, among other, will allow customers to view and amend their account (e.g upgrade or customise packages) and also pay their bill in real-time Executives hope that this will help ease customer sales staff and allow them to focus on additional customer queries The mobile application initiative is mainly driven by the Marketing department of the company, with the Marketing Director, Mr Smith, believing that this will help boost their subscriber base and help them build new, meaningful customer relationships He believes that the key to increased market share is having both pure online and hybrid telephone ordering capabilities, as well as recognising the need to “go out and find customers and not wait for them to come to us” Therefore the mobile application is seen as a way to target the younger audience and more business-oriented people, who are always more inclined and more used to using their mobile phones and/or tablets for purchasing With the development of the new app, the company will have to move to a new CRM system which will allow them to ‘push’ sales by profiling customers and offering special deals directly through their mobile app You are consultants, called to assist MobilesForAll.com LTD with the development of their mobile app for customers They have a tight deadline of months for the app to go live, any needed staff training should happen within weeks and the analysis, design and development of the new app should be within the budget of 80.000 pounds as decided by the Senior Management of the company Below is a description outlining the functionality of the new mobile app and of the new CRM system: Customers and potential customers can browse and search for packages or deals of interest via their Android mobile phone A package is a combination of a number of products, such as the actual device (mobile, tablet or router) and also the number of free minutes, number of free SMS, number of free GB etc Customers can choose from a number of packages, such as MobileOnly, BroadbandOnly, TabletOnly, which are considered to be the default packages provided by the company However, they can also even customize their own package based on their individual mobile and/or broadband usage (which they would be able to view via the app) and any other special requests Customers can also choose from a number of deals such as the DoublePackage deal (including a combination of any two packages) or the TriplePackage deal (including all three packages) Customers can make a general enquiry or an enquiry about a specific package or deal An order can be placed either online, in person, through phoning the Sales department or by the customer via the mobile app Ordering via the app, however, is given an automatic 15% discount, for promotional purposes If the order is made via the app, then the customer will have to first register by creating an account with their personal details (thus creating a profile containing all relevant information to the customer, such as name, email, address and credit card details), then choose the new/upgrade package via a menu that appears on-screen and then the order is processed electronically by the new CRM Customers can also use the app to view or amend their account and also settle their bill in real time When customers would like to settle the bill, they should be able to login first The only means of payment permitted is credit card The checking of credit card details will be done by the company’s bank, through a link to a system known as VISACheck After the payment is finalised, the Customer Sales Representatives (CSR) will trigger the system to send an email receipt to the customer If a customer phones the Sales department to place an order, then the CSRs will have to follow a verification process to attempt to identify the person calling, even if they are new, and will then be able to bring up an existing customer account or create a new account for new customers The CRM system should also allow sales representatives to access all packages in order to inform the customer accurately about prices and products and also allow them to deal with any enquiries submitted from a customer via the app The CRM system should furthermore be able to check whether the packages selected by customers are available, calculate the total, process a payment and verify card details The total of an order would be the sum of the deal or package required, minus the discount and/or minus the special offer (depending if the customer would like to use the special offer code) The customer sales representatives should finally have the capability to profile customers based on the packages they use Based on these profiles, special offers will be created and sent to the customers via their app The customers can use these special offers by typing the special offer code directly into the app The company’s president, Mr Brown backs the new app and the new CRM system they have to move into, and believes that it will provide an ideal opportunity to ‘push’ sales through profiling customers and offering special deals This move aims to cut costs significantly, provides a better way to cope with rapid growth and increases revenues through customer profiling He believes that this new app will improve existing customer satisfaction, which is his number one priority The Sales Director of the company, Mr Jones, however, has different ideas about the new app He believes that they need to reach out to new customers and try to attract customers of different ages and backgrounds rather than just targeting the younger audience The customer Sales Representatives on the other hand are not very excited with the decision to move to the new CRM system which will support the mobile app They feel that dealing with customers in person is better and actually this is what makes them coming back They feel that the reason the online system was not widely used was the lack of personal contact and therefore they are more in favour of furthering the development of the online system to provide a realtime support by them rather than spending thousands of pounds for building an app They believe that their friendly and welcoming approach as well as their ability to customize packages for customers is irreplaceable Nevertheless, they still express concerns about losing their job as they believe that the new CRM system will replace their responsibilities Requirements Individually and as a group, you should Discuss within your cw team - the Ps relevant to the given case study and document them Produce a preliminary design using traditional, structured methodologies, covering the full functionality of the proposed new system The design should include: • Entity Relationship Diagram which represents the Conceptual Data Model of the scenario described in the case study as captured by discussions with the client You are required to distinctly show all entity types, attributes (including primary key attributes) and relationships, as well as determine the structural constrains (cardinality and participation constrains) of each relationship Data Flow Diagram which represents the Process Model of the specific functional requirements based on the same case study that you modelled against for the Entity Relationship Diagram You are required to include the level DFD (context diagram) only Implement a database based on the design produced as per above requirements The prototype database is to be built using any competent

product to the system (you should indicate its category/type, e.g., mobile, tablet or router etc) • Delete a product • List all products for a particular category/type • Create/Customise a package • Create an order for package (with date and time stamp) for a particular customer • Pay for a billl Create the proposed system design using object-oriented methodologies, to allow for more flexible design/build iterations and re-use of design and code The design should include • Use Case Analysis - A UML Use Case diagram identifying all actors and their Use Cases • Interaction Diagrams Using UML sequence (interaction) diagrams perform an analysis of three main Use Case scenarios • Design UML Class Diagram – Show all attributes, methods, and associations with multiplicity for all main classes

attach to the report a pro-forma (included the end of this document) that will enumerate all the tasks that your group tackled and completed as part of this coursework, and the involvement of each member of the group in each task This will be used in part to establish the individual contribution of each member of the group The pro-forma must be agreed and signed by all members of the group h) An appendix with i) Any additional functionalities extracted from the discussion with the client or you proposed as assumptions (subject to the client’s agreement) ii) A short personal discussion regarding your role, your contribution within the group and how you liaised with the other team members 2) System prototype demonstration As part of the software development cycle an acceptance testing will need to be carried out For the acceptance testing your group needs to a presentation to the client (in this case your tutor) to demonstrate the design and the prototype database you have built For your demonstration create a short ppt presentation (2-3 of slides per member) The presentation should include an introduction of the team members and their roles Within the presentation you are going to demonstrate the required business functionality and show the adherence of the implemented system to the submitted design 10 Grading Criteria 80-100 Exceptional 70-79 Excellent 60-69 Very
