Criterion B Summative

When  designing any computer system, Data Flow Diagrams (DFDs) are used to produce detailed logical models of the current system.

Your individual task for this stage is to research and read more about Data Flow Diagrams (DFD).

Use the resource link below for examples and guidance

http://www.sqa.org.uk/e-learning/SDM03CD/page_07.htm

As an individual, you will develop an outline of any unique statements (situation) different from the examples in the link above and develop a DFD diagram to model the situation outlined above. i.e Red Dragon Company situation.

Design Assessment Rubric



Levels
Descriptors
0
The design does not meet the standards of the descriptors shown below.
1-3
The design shows limited development of instructions statements (situation) thus not suitable for the development of the DFD. The DFD structure developed is not detailed, not logical and uses limited standard DFD symbols in it’s presentation. Limited processes are used to show the flow of data in the system of choice.
4-6
The design developed shows some good instructions statements (situation) that can be used to develop a good DFD. The DFD structure developed is detailed, logical and uses a range of DFD symbols in its design. Some important processes are used to show the flow of data in the system of choice.
7-8
The design shows that most of instruction statements are comprehensive thus useful in developing a thorough DFD structure. The DFD structure developed is comprehensive, detailed, logical and uses a variety of standard DFD symbols appropriately. Several important processes are used to show the flow of data in the system of choice in a comprehensive way.

CASE STUDY

Criterion A: Inquiring and analysis


In this stage you will work in groups to market your Taxi information systems owned by your company. You will be expected to prepare a detailed and professional presentation to the owners of Red Dragon Taxi Company (Family of Yao Chu). The following will be your deliverables;

a)    A presentation that will last for 10 minutes with 3 minutes for set-up. The presentation should;
·        Allow each member of the group to participate fully in the presentation
·        Show graphical, video, animations evidence of the product's main features
·        Briefly describe what are the main problems of the Red Dragon Taxi Company
·        Outline the main strengths and limitations of the new proposed Taxi IT system.
·        Outline the unique features (specs) of the new proposed system
·        Explain the support they will provide once the system is implemented.
·        Show evidence of clients who use their product

b)    A detailed A3 poster that Red Dragon Company can use to market their services. (Poster should have more illustrations than text and printed)

c)    Detailed video advert that Red Dragon Company can use to advertise the new services (Maximum time 30 secs)

d)    Detailed interactive brochure for the Company that can be shared online. The brochure should be interactive and have;

·   The Video advert inserted
·   Audio customer reviews included
·   Relevant images inserted
·   Must have a maximum of 8 pages A5 brochure.
From the Case study document you must now know their systems limitations and the systems requirements. The choice of the TAXI IT management system should be able to address most if not all of their requirements.

The mode of presentation will be left to your group to decide. However, the choice of presentation should be captivating, interesting and with deep knowledge and understanding of the concepts related to modern Taxi management information systems. 

No similar Taxi IT systems should be presented by the same group. A company cannot send two groups to present the same product.  

Each group should be prepared to answer one or two questions related to the case study. The response to the question should be supported with evidence from research.
