you are ready to execute the next phase in system development life cycle (SDLC), which is the design phase. Exploiting the research that you have performed in this week’s Discussion Board on the set of modeling tools, document the design for the application project that you selected. 

Assignment

For this assignment, you will use Visio Software Application to develop the design employing the following computer-aided software engineering (CASE) modeling tools:

• Use case  Functional decomposition diagram  Entity-relationship (E-R) diagram, data flow diagram (DF), or class diagram  Sequence diagram    
• Mock-up or storyboard of the user interface screens 

The project deliverables are as follows:

• Update the System Requirements, Design, and Implementation Specification title page with new date.  Update the previously completed sections based on the instructor's feedback.  

System or Application Design   

• Develop a high-level use case to represent the application as a whole.  Develop a functional decomposition diagram to show all of the functions that the system or application will support.  Develop an E-R diagram, class diagram, or a data flow diagram that effectively represents the data that are required for your application or system.  Develop a sequence diagram to represent the timing of various activities within the application or system.      
• Develop a mock-up or storyboard for the high-level interface screens.

Chalmers Corporation operates in multiple areas of the globe, and relatively large price changes are common. Presently, the company sells 170,000 units for $50 per unit. The variable production costs are $20, and fixed costs amount to $2,086,000. Production engineers have advised management that they expect unit labor costs to rise by 10 percent and unit materials costs to rise by 15 percent in the coming year. Of the $20 variable costs, 25 percent are from labor and 50 percent are from materials. Variable overhead costs are expected to increase by 20 percent. Sales prices cannot increase more than 12 percent. It is also expected that fixed costs will rise by 10 percent as a result of increased taxes and other miscellaneous fixed charges. The company wishes to maintain the same level of profit in real dollar terms. It is expected that to accomplish this objective, profits must increase by 8 percent during the year. Required: a. Compute the volume in units and the dollar sales level necessary to maintain the present profit level, assuming that the maximum price increase is implemented. b. Compute the volume of sales and the dollar sales level necessary to provide the 8 percent increase in profits, assuming that the maximum price increase is implemented. c. If the volume of sales were to remain at 170,000 units, calculate the new price that would be required to attain the 8 percent increase in profits? Calculate the new price. Note: Round your answer to 2 decimal places. Complete this question by entering your answers in the tabs below. Required A Required B Required C Compute the volume in units and the dollar sales level necessary to maintain the present profit level, assuming that the maximum price increase is implemented. Note: Do not round intermediate calculations. Round up your answer for "Volume in units" to the nearest whole number and round your answer for "Sales" to the nearest whole dollar amount.
