Systems analysis and design Number Part Project Management (a) Network Diagram (b) the shortest completion time is calculated by taking the shortest route that a project can be completed. This is obtaied by taking the shortest route that can be taken to complete the project. 2 weeks+3 weeks +3 weeks +7 weeks +3 weeks +4 weeks +2 weeks = 16 weeks. (c) the critical path is the path that is highlight in red. This is the longest time that a project can take to be completed and hence need to be checked by apply crash program methods. (d) If the duration for activity 6 is increased from one week to 6 weeks, thwe changes that will be our depend on the float time. If float time is zero, then the completion time will be increased from 16 weeks to 22 weeks. This will have affected the organisation in terms of resources due to delay. If the float time is six or more weeks then the project completion time is not affected (e) Gantt chart for the project Part 2 Case Study List of use cases Use case name Description Actor Call logging management Involve the all the details concerning the customers that make call such as prepaid customer service and postpaid customer service Chief Medical Officer EMT management This use case connect emergency calls to the appropriate response Supervisors Rescue team management This is for EMT management activities such as dispatching and monitoring supervisors Base station management Tracks caller on the state of responding to the emergency Call center operators Report production This use case entails the demand report, spanning report and exception report Rescue911 manager Master file maintenance This describes keeping of all the files that involve different section of the organization such as the records about employees Rescue911 manager Response team records management This include details about rescue team such as the experience, success in an operation, reporting to duty Medical manager Subscriber records management Involve both direct and indirect subscriber records and there payment records Operation manager Finance processing This use case includes information and records for billing, vehicle and asset management; and accounting and finance. Finance manager 3. Detailed description of Log Emergency Call” use case Use case: log Emergency call ID: UC2 Scope: The person that operates the system receives an incoming call then he/she enters the details of the incident then the appropriate emergency medical team is dispatched. Stakeholders: The person that made the emergency call The medical manager who decides the suitable EMT to attend that particular case. The core actor: The emergency center operator that is on duty Precondition: The person operating the system must enter the user name and the password, Trigger: The call that has been made by the victim is channeled to the operator by the system in the call center Successful operation entails: The call made by the client is recorded. The EMT has been send to the scene of the incident. The details of the incident are recorded and stored I the system During an ideal success scenario: The call system starts by taking down the details of the call. Then it tries to identify the physical location of the caller using the address. After that the operator notes the location of the incident. The system then checks the number of EMT that are on duty and available for dispatch at that particular time. The system then gives the list of available EMT ant their proximity to the place where the incident is. The operator identifies the EMT to attend to that particular case according to the experience and the severity of the case. Then the system sends the details of the incident to the EMT that has been identified to handle that case. Lastly the system saves all the details about the entire operation then s it terminates the recording. Variation If the call made is via a mobile phone, then the operator is supposed to identify the location of the caller. For the case of a caller who makes a call for no apparent reason the system terminate the operation and lowers the priority given to that caller. When the incident is minor that only first aid can be administered, the first aid instruction of the case is sent and the operation terminated. When the severity of the incident is critical, then a more experienced team of EMT is dispatched. In a situation where the the physical location of the caller cannot be identified, the system prompt the operator to reduce the priority of that case on the basis of inability to identify the location and hence the operator decide on the priority level to accord. The all EMT teams are engaged in other cases the, the system gives the operator the reason why low priority is given to the incident. When there is breakdown in communication between the system and the EMT team who is supposes to attend a case, the system repeats the procedure of connecting the team. In case there is an issue with the communication in all the units, the dispatch is availed by use of mobile after the system has provided the necessary details about the incident. The system must put in consideration other requirement that is non-behavioral for example ensuring that the process of locating a free EMT should take the least time possible. The screens that are presented to the operator should be few to avoid complexity and also the message that is passed between the EMT team and the other unit be secured using encryption methodologies to prevent eavesdrop attacker who might have malicious intention (4) Entity relationship diagram (5) Decision table ID Type Verify Method Risk Status 1 Functional Test High approved 2 Functional Test High Approved 3 Functional Test Medium Approved 4 Functional Test Medium Approved 5 Functional Test Medium Approved 6 Functional Test Low Approved 7 Functional Test Medium Approved 8 Functional Test Low Approved 9 Functional Test Low Approved 10 Functional test Low Approved 11 performance Demonstration high approved (6) Activity Diagram.
