a.

Explanation of Solution

Project initiation and focus for the new system:

  • The initiation for the project is done by a group of business people, high level managers, and committees of organization and so on.
  • All these people help to complete the project in an efficient manner.
  • There are three main focuses for the development of a new information system as follows:
    • People who are involved in the project such as team members or high...

Explanation of Solution

Modified economic feasibility analysis for customer tracking system:

Monetary benefits of an information system = $50,000 per year.

One-time costs = $47,500

Recurring cost = $32,000 per year.

Discount rate = 10%

Time period = 5 years

Present value for benefits and costs can be calculated by using the formula:

  PVn= Y × 1/(1+i)n

Here, PVn is the present value and i is the discount rate.

Present value (PV) calculation for benefits:

Benefits starts from year 1, hence calculation of present value starts from year 1.

PV0= 0 × 1 / (1+ 0.10)0= 0×1 = 0

PV1= 50,000 × 1/ (1+.10)1= 50,000×0.909 = 45,450

PV2= 50,000 × 1/ (1+.10)2= 50,000×0.8264 = 41,320

PV3= 50,000×1/ (1+.10)3= 50,000×0.7513= 37,565

PV4= 50,000×1/ (1+.10)4= 50,000×0.683 = 34,150

PV5= 50,000×1/ (1+.10)5= 50,000×0.6209 = 31,045

Net Present Value (NPV) for benefits:

 NPV = PV0+ PV1+ PV2+ PV3+ PV4+ PV5            = 0 + 45,450 + 41,320 + 37,565 + 34,150 + 31,045        = 189,530

Present Value (PV) for costs:

PV0= 47,500×1/ (1+.10)0= 47,500×1 = 47,500

PV1= 32,000×1/ (1+

c.

Explanation of Solution

Modified Economic Feasibility Analysis for Customer Tracking System at discount rate(12%):

Monetary benefits of an information system = $50,000 per year.

One-time costs = $47,500

Recurring cost = $32,000 per year.

Discount rate = 12%

Time period = 5 years

Present value for benefits and costs can be calculated by using the formula:

  PVn= Y × 1/(1+i)n

Here PVn is the present value and i is the discount rate.

Present value (PV) calculation for benefits:

Benefits starts from year 1, hence calculation of present value starts from year 1.

PV0= 0 × 1 / (1+0.12)0= 0×1 = 0

 PV1= 50,000 × 1/ (1+.12)1= 50,000×0.8929 = 44,645

PV2= 50,000 × 1/ (1+.12)2= 50,000×0.7972 = 39,860

PV3= 50,000×1/ (1+.12)3= 50,000×0.7118 = 35,590

PV4= 50,000×1/ (1+.12)4= 50,000×0.6355 = 31,775

PV5= 50,000×1/ (1+.12)5= 50,000×0.5674 = 28,370

Net Present Value (NPV) for benefits:

NPV = PV0+ PV1+ PV2+ PV3+ PV4+ PV5            = 0 + 44,645 + 39,860 + 35,590 + 31,775 + 28,370        = 180,240

Present Value (PV) for costs:

PV0= 47,500×1/ (1+.12)0= 47,500×1 = 47,500

PV1= 32,000×1/ (1+.12)1= 32,000×0.8929 = 28,572

PV2= 32,000×1/ (1+.12)2= 32,000×0.7972 = 25,510

PV3= 32,000×1/ (1+.12)3= 32,000×0.7118 = 22,777

PV4= 32,000×1/ (1+.12)4= 32,000×0.6355 = 20,336

PV5= 32,000×1/ (1+.12)5= 32,000×0.5674 = 18,156

Net Present Value (NPV) for costs:

NPV = PV0+ PV1+PV2+ PV3+ PV4+ PV5           = 47,500 + 28,572 + 25,510 + 22,777 + 20,336 + 18,156           = 162,853

Overall Return on Investment (ROI):

Overall return on investment can be calculated as:

Overall ROI = (Overall NPV / NPV of all costs)

Overall NPV = (NPV of all benefits – NPV of all costs)                       = 180,240 – 162,853                       = 17,386

Overall ROI = 17,386 / 162,853                   = 0.1

Break-Even Analysis (BEA):

  • Break even analysis is carried out by determining NPV of yearly cash flows.
  • The yearly cash flows are calculated by subtracting present values of recurring costs from the present value of yearly benefits.
  • The overall NPV cash flow is total cash flow of the preceding years.
  • After determining NPV yearly cash flows, it is found that break even occurs between years three and four

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid."

Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters, bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0. For example, Letter 'h' Binary ASCII 01101000 68H 'H'…
