System Proponent

Provide the name of the System Proponent.

History of the System

Briefly describe the system’s history and predecessor, if any. State the mission needs and information requirements, including how the system is expected to help users.

Functional System Description and Data Usage

Briefly describe what the system does functionally and how the data are used by the system.

Explanation:

Overview

The Post-Implementation Review is used to evaluate the effectiveness of the system development after the system has been in production for a period of time (normally 6 months). The objectives are to determine if the system does what it is designed to do: Does it support the user as required in an effective and efficient manner? The review should assess how successful the system is in terms of functionality, performance, and cost versus benefits, as well as assess the effectiveness of the life-cycle development activities that produced the system. The review results can be used to strengthen the system as well as system development procedures.

The review is scheduled to follow the release of a system or system revision by an appropriate amount of time to allow determination of the effectiveness of the system. A representative from the functional development group or other member of the major user organization participates in the review. The System Proponent ensures that all documentation and all personnel needed to participate in the review are accessible.

The reviewer and an assigned team collect the information needed for the Post-Implementation Review by interviewing end users and their managers, system administrators, and computer operations personnel. The report is then prepared and provided to the user organization that requested it and the information systems organization, which may jointly use the findings to initiate other actions.

The Post-Implementation Review is a free-form report, and not all sections are relevant or necessary to the final product. A description of the Post-Implementation Review Report is attached.

The original U.S. income tax of 1913 was quite simple. The tax was

Svetradugi [14.3K]

Answer:

Scanner inputObject = new Scanner(System.in);

System.out.print("Enter your income to calculate the tax: ");

double income = inputObject.nextDouble();

double tax = 0;

if (income <= 50000) {

tax = income * 0.01;

}

else if (income > 50000 && income <= 75000) {

tax = income * 0.02;

}

else if (income > 75000 && income <= 100000) {

tax = income * 0.03;

}

else if (income > 100000 && income <= 250000) {

tax = income * 0.04;

}

else if (income > 250000 && income <= 500000) {

tax = income * 0.05;

}

else if (income >= 500000) {

tax = income * 0.06;

}

System.out.printf("Your tax is: $%.2f", tax);

Explanation:

Here is the Java version of the solution. The user is asked to enter the income and the tax is printed accordingly.

Scanner class is used to take input from user, and the value is stored in income variable. A variable named tax is initialized to store the value of the tax.

Then, if structure is used to check the income value. This income value is checked to decide the amount of the tax will be paid. For example, if the income is $100000, the tax will be calculated as tax = 100000 * 0.03 which is equal to $3000.00. After calculating the tax value, it is printed out using System.out.printf("Your tax is: $%.2f", tax);.

Be aware that the values are double, printf is used to print the value. "%.2f" means print the two decimal values in the result.
