Develop A Context Diagram And Nested DFDs

743 Develop A Context Diagram And As Many Nested Dfds As You Consider

Develop a context diagram and as many nested DFDs as you consider necessary to represent all the details of the training logistics system described in the following narrative. If you discover that the narrative is incomplete, make up reasonable explanations to complete the story. Supply these extra explanations along with the diagrams. Training, Inc., conducts training seminars in major U.S. cities. For each seminar, the Logistics department must make arrangements for the meeting facilities, the training consultant’s travel, and the shipment of any seminar materials.

For each scheduled seminar, the Bookings department notifies the logistics coordinator of the type of seminar, the dates and city location, and the name of the consultant who will conduct the training. To arrange for meeting facilities, the logistics coordinator gathers information on possible meeting sites in the scheduled city. The meeting site location decision is made based on date availability, cost, type of meeting space available, and convenience of the location. Once the site decision is made, the coordinator speaks with the sales manager of the meeting facility to reserve the meeting room(s), plan the seating arrangement(s), and reserve any necessary audiovisual equipment. The coordinator estimates the number and size of meeting rooms, the type of seating arrangements, and the audiovisual equipment needed for each seminar from the information kept in a logistics database on each type of seminar offered and the number of anticipated registrants for a particular booking.

After negotiations are conducted by the logistics coordinator and the sales manager of the meeting facility, the sales manager creates a contract agreement specifying the negotiated arrangements and sends two copies of it to the logistics coordinator. The coordinator reviews the agreement and approves it if no changes are needed. One copy of the agreement is filed and the other copy is sent back to the sales manager. If changes are needed, the agreement copies are changed and returned to the sales manager for approval. This approval process continues until both parties have approved the agreement.

The coordinator must also contact the training consultant to make travel arrangements. First, the coordinator reviews the consultant’s travel information in the logistics database and researches flight schedules. Then the consultant is contacted to discuss possible travel arrangements; subsequently, the coordinator books a flight for the consultant with a travel agency. Once the consultant’s travel arrangements have been completed, a written confirmation and itinerary are sent to the consultant. Two weeks before the date of the seminar, the coordinator determines what, if any, seminar materials (e.g., transparencies, training guides, pamphlets, etc.) need to be sent to the meeting facility.

Each type of seminar has a specific set of materials assigned to it. For some materials, the coordinator must know how many participants have registered for the seminar in order to determine how many to send. A request for materials is sent to the Materials-Handling department, where the materials are gathered, boxed, and sent to the meeting address listed on the request. Once the requested materials have been shipped, a notification is sent to the logistics coordinator.

Paper For Above instruction

Developing a comprehensive system model for the training logistics process at Training, Inc. involves creating a context diagram and nested Data Flow Diagrams (DFDs) that illustrate the flow of data, decision points, and interactions among various entities involved in organizing and executing training seminars. The goal is to depict all critical functions—from booking and site arrangements to travel coordination and materials distribution—within a clear, structured framework that aids understanding and system development.

Introduction

The process begins with the Bookings department scheduling a seminar and notifying the logistics coordinator of essential details like seminar type, date, city, and trainer. The logistics department then assumes responsibility for coordinating all logistical aspects to ensure the seminar's success. This system model captures the data interactions, decision points, and external entities involved, providing a detailed blueprint for the operational flow at Training, Inc.

Context Diagram

The context diagram depicts the overall training logistics system as a single process, with external entities interacting with it. These entities include the Bookings department, Sales Managers of meeting facilities, Training Consultants, Materials-Handling Department, and Meeting Participants. The primary data flows involve seminar schedules, facility and travel arrangements, contract agreements, travel itineraries, seminar materials requests, and notifications of shipment completion.

Nested Data Flow Diagrams (DFDs)

The nested DFDs break down the main process into manageable subprocesses, detailing how data flows between the various functions. Key subprocesses include:

• Seminar Scheduling and Notification: The Bookings department inputs seminar details and notifies logistics.
• Meeting Facility Arrangements: The logistics coordinator researches, negotiates, and reserves meeting sites, creating and approving contracts.
• Travel Arrangements for Consultants: Logistics reviews travel info, researches flights, books travel, and confirms itineraries.
• Materials Planning and Shipment: The coordinator determines materials needed, requests shipment from Materials-Handling, and tracks shipment notifications.

Each subprocess interacts through defined data flows, with decision points such as contract approval, site selection criteria, and material quantities based on registration numbers. Additional explanations incorporate reasonable assumptions where narrative gaps exist, such as the existence of a logistical database, the process for handling contract modifications, and protocols for emergency or unexpected changes.

Conclusion

This set of diagrams provides a comprehensive view of the training logistics at Training, Inc., facilitating a clear understanding of data movements and process responsibilities. Such a model supports system development, process optimization, and effective management of training events, ensuring seamless coordination from initial booking to final shipment of materials.
