(use a short paragraph to introduce this section and each diagram, table or illustration should use about ½ of a page)Output Layout #1.Output Layout #2.Output Layout #3.Input Layout.  Using the data elements listed in yourn Requirements Specification, create a diagram or table illustrating what the input screen would look like for each of the three sets of input.  (use a short paragraph to introduce this section and each diagram, table or illustration should use about ½ of a page)Input Layout #1.Input Layout #2.Input Layout #3.File/database Design ERDs.  For each of the three sets of outputs and inputs, create an Entity Relationship Diagram showing how the data elements are related to each other [see explanation at http://academic.regis.edu/ladams/Diagramming%20101.html].  Depending on the inputs and outputs identified, there may be some overlap of the data elements in the ERDs; a separate ERD should be developed for each pair of inputs/outputs.  (use a short paragraph to introduce this section, and each ERD should be on one page)File/database Design ERD #1.File/database Design ERD #2.File/database Design ERD #3.

Submitting Your Assignment

Submit your Requirements Specification and System Design Specification as one document via your Assignment Folder as Microsoft Word document, or a document that can be ready using MS Word, with your last name included in the filename.  Use the Grading Rubric below to be sure you have covered all aspects of the assignment.

Stage 3:   System Design Specification
Stage 3: System Design Specification Before you begin this assignment, be sure you have read the Case Study and all

 

assignments for this class, especially Stage 4: Final System Report. The feedback you

 

received on your Stage 1 and Stage 2 assignments should be reviewed and used as you

 

proceed with Stage 3.

 

Purpose of this Assignment

 

This assignment gives you the opportunity to apply a systematic approach to translate

 

requirements into a high-level logical system design. This assignment specifically addresses

 

the following course outcomes to enable you to: apply a systematic approach to translate requirements into an executable systems

 

design

 

effectively communicate with stakeholders to determine, manage, and document

 

business requirements throughout the SDLC Assignment

 

The results of your systems analysis and design work in this class will be documented in a

 

Final System Report. The purpose of the Report is to inform management of your system

 

proposal and gain approval to proceed with the project. The Report will be developed and

 

submitted in stages, which will be compiled at the end of class into the Final System Report.

 

Review the outline of the Final System Report in the Stage 4 Assignment description. Note

 

that it contains the analysis of the problem(s) and requirements, and proposes what kind of

 

a system solution is needed. It does not propose a specific solution, but it does recommend

 

why and how the organization should acquire the solution.

 

Following the Requirements Specification (Stage 2 assignment), the next step is to develop

 

the System Design Specification. The System Design Specification builds on the

 

Requirements Specification to illustrate how the files/database(s) will be laid out, how the

 

output (forms, reports, and/or screens) and input (forms and/or screens) should be designed.

 

As you develop this assignment, you should refer to your Stage 2 Requirements Specification

 

(and the feedback you received) and use the inputs and outputs you listed to create the

 

input and output layouts and the file/database design.

 

All of the information you need to complete the projects in this class is not provided in the

 

case study. In the discussion area of the classroom, there is a discussion titled &quot;Case Study

 

Interview Questions&quot; where you can pose questions about the case study, as if you were

 

interviewing the people in the case study organization. Any information that you need that

 

is not included in the case study should be asked about in this discussion. Responses from

 

the faculty member on behalf of the case study organization will be available for everyone in

 

the class.

 

Use the case study and the Case Study Interview Questions discussion, along with your

 

Stage 2 Requirements Specification (including the feedback received), and resources below,

 

to create a System Design Specification in the format shown below. Include your corrected

 

Stage 2 Requirements Specifications as the first part of this assignment. Approximate

 

lengths for each section of the Systems Design Specification are provided as a guideline; be

 

sure to provide all pertinent information. The sources of explanatory materials can be found

 

in the Week 5 Content readings. Stage 3: System Design Specification 1 Requirements Specification

 

Include your Requirements Specification from Stage 2, with corrections from the

 

feedback included. This will establish the context for your System Design Specification to

 

follow.

Output Layout. Begin with the three outputs listed in your Requirements

 

Specification. For each of them, create a diagram or table illustrating what the

diagram, table or illustration should use about ½ of a page)

 

A. Output Layout #1.

 

B. Output Layout #2.

 

C. Output Layout #3.

 

Input Layout. Using the data elements listed in your Requirements Specification,

 

create a diagram or table illustrating what the input screen would look like for

 

each of the three sets of input. (use a short paragraph to introduce this section

 

and each diagram, table or illustration should use about ½ of a page)

 

A. Input Layout #1.

 

B. Input Layout #2.

 

C. Input Layout #3.

 

File/database Design ERDs. For each of the three sets of outputs and inputs,

 

create an Entity Relationship Diagram showing how the data elements are related

 

to each other [see explanation at http://academic.regis.edu/ladams/Diagramming

 

%20101.html]. Depending on the inputs and outputs identified, there may be

 

some overlap of the data elements in the ERDs; a separate ERD should be

 

developed for each pair of inputs/outputs. (use a short paragraph to introduce

 

this section, and each ERD should be on one page)

 

A. File/database Design ERD #1.

 

B. File/database Design ERD #2.

 

C. File/database Design ERD #3. Submitting Your Assignment

 

Submit your Requirements Specification and System Design Specification as one document

 

via your Assignment Folder as Microsoft Word document, or a document that can be ready

 

using MS Word, with your last name included in the filename. Use the Grading Rubric below

 

to be sure you have covered all aspects of the assignment.
