Tasks

These all relate to the description of Disaster Relief Co-ordination (DRCS) system given below. This description should not be regarded as complete but can be regarded as accurate (in other words you can expand upon it but your answer should not contradict it). You may want to investigate similar dating agency websites for ideas! Please note that there are no absolutely definitive (or correct) answers to these. You will be assessed on your ability to present the requirements in a clear and logical manner, the way you have addressed the description of the system provided, and the quality of your discussion of the issues arising.

Note that you are required to present requirements and models for the new system at DRCS – much of the discussion below relates to the current system. It is important to draw the diagrams using a UML case tool. For each section some marks will be given for some explanation and design choices.

1.       Draw a use case diagrams and produce 2 overall Activity Diagrams including swim-lanes and the transitions of use cases. [12]

2.       Produce 4 Prototypes presented as a storyboard [12]

3.       Using the MVC pattern, produce 4 Sequence Diagrams corresponding to the 4 Prototypes [16]

4.       Draw a class diagram and consider 1 class and from that draw a state-chart diagram [12]

5.       Consider the class diagram in point 4 above and via object relational mapping develop an entity relationship diagram ERD. [16]

6.       Consider 1 sequence diagram from 3 above and your class diagram write the basic Java code including the name of the class, attributes (including the relationships with other classes). Also include the method name but not the method details. [16]

7.       Redraw the Zachman Framework and complete it further considering where all the diagrams drawn in this coursework would be presented and show where the component and deployment diagrams would be presented as well. (Please note: you don’t need to actually draw a component or deployment diagram for this coursework). [16]

You are part of a team of systems analysts working for an IT consulting firm that have  been hired to develop a  specialised system  for the government of Lazarus Island. The IT consulting firm has its own staff with skills of Agile Project Management, business analysis, system development, programming and testing.

The island is located in the South Pacific, about 350 miles from Ecuador and has a population of 80,000.

Your team have been developing systems using an Agile Methodology for the last 10 years and they are very competent in using     the DSDM Agile Project Management Framework and the SCRUM methodology. The team have  decided  that  this particular  project will adopt the DSDM Agile Project Management framework to develop the system.

What you are getting yourself into:

As mentioned earlier, your firm has been commissioned by the government of Lazarus Island to design and build a  specialised  system for them. The island has been subjected to a number of natural disasters such as cyclones, hurricanes and recently an earthquake. The government receives a lot of offers of assistance, donations and actual resources such as food, clean water, medical supplies, temporary shelters etc. whenever disaster struck  but  their approach to handling relief (and the  disasters in general) has  been poorly coordinated.

To add some perspective, dealing with disasters is a complex process and managing a disaster is usually done in 2 stages:

§  Response

§  Recovery

You can learn more about Disaster Relief and Coordination from various resources such as: the Emergency Management UK portal

http://www.emergencymanagement.org.uk/

Also there are some useful articles on Disaster Management e.g. DEC, which brings together several UK charities, and Red Cross:

http://www.dec.org.uk/    and https://www.ifrc.org/en/

You should carry out further literature review to help you understand the requirements in more detail.

The System that needs to be created:

The system that needs to be created would be used in the response stage of disaster management, specifically the part that deals     with ensuring the basic  needs of people affected by the disaster are met by government agencies and humanitarian organisations.  This is a crucial stage in response to a disaster as people are cut off from basic supplies and left in exposed, substandard living conditions can fall foul of disease and malnutrition.

Your role is to draw up a specification for a system that will help them to better coordinate their relief effort. This system should be web based so computers and mobile devices can access it. The system needs to be secure and only people authorised to use the  system should be able to access it. The disaster relief coordination system (code-named Aegis) should be designed to enable government and non-government organisations to coordinate efforts in the relief phase following a natural (or man-made) disaster. The system should be made  up of a  number of modules that enable these organisations to work together and share information on  the disaster so that resources can be deployed in the most effective way possible.

The Aegis System is made up of the following sub-systems:

§  Mapping and Geo-location System (using the Google Maps API or a more reliable mapping API)

§  Resource Management System (for cataloguing and tracking inventory such as medicines, equipment, etc.)

§  Organisation Management System (where staff are associated with organisations)

§  Situation Management System (allowing situations to be ‘raised’ that list requirements)

All organisations can add markers onto an interactive map highlighting areas of need, current locations of relief workers, camps, supply points, last location of missing/found people etc. These different marker groups can be activated and deactivated as needed    to improve readability and focus of the map. Organisations will be able to communicate with one  another through messaging  services and can add workers’ mobile numbers so that they can send/receive status updates.

Part of the requirements for the system is that it will need to incorporate a submit/approve process whereby a non-governmental organisation can submit information that needs to be approved by the appropriate government agency. This only applies to certain requests such as medical supplies, desalination equipment, shelter construction and support  request  that  go  beyond basic grain, milk, water and emergency shelter provision. The process is also used in confirming situations raised by workers from Non- Government Organisations. You can consider a typical ‘situation’ as being the discovery of local(s) directly affected by the disaster and in need of resources that will provide for their basic needs and health. There have been occasions in the past where workers for NGOs invented situations so that they could get resources that were not needed in order to sell them on privately.

Who are the users:

A number of people will be stakeholders regarding the development of the Aegis system. Only the  hands on users,  those  that directly use the system as a core part of their job are listed here along with their basic use of the system. It is likely that there are  other users of the system that have not been listed below.

Government Agency Administrator: They would be using the system to enrol and  manage  Non-Government  Orgainsations (NGO) e.g. Red Cross, Oxfam.

The government agency administrators would setup/confirm requests for resources as well as manage and allocate resources to  NGOs. Resources are stored at resource hubs and are then despatched to places that are requesting them. Resources are never requested or allocated individually. They are bundled up into resource packages that contain essential resources.

The administrator would also identify situations from information provided by the national and local emergency services. They  would also have to approve situations proposed by NGOs. Both would result in a request for assistance being generated that they could allocate to an NGO to deal with. A situation will only be approved by a government admin as soon as one of the emergency services (police, ambulance, fire brigade etc.) have visited the situation and confirmed that it is real.

NGO Administrator: These individuals act as the main contact and coordinator between government administrators and the NGO. They identify their main base camps, update worker lists and profiles and also ensure that the last known locations of workers have been updated. They also identify and build teams from their worker lists to deal with requests for support.

They can identify situations for approval by government admin and offer to respond to requests for assistance.

An NGO admin can request resources for teams that are dealing with support requests. They can also offer to provide resources and set up the NGO resource hubs from where their resources would be despatched.

NGO Worker: They are the  ones who are  out  in the  field providing the relief work. Workers in the field can keep their profile up to date ensuring that their correct skills and expertise are stored. Workers can also update their current location so that NGO administrators know where they are and how far they are from areas that need assistance.
