C# ProgramGeneral Background Information:CMS Systems, Inc. is a company that provides information systems

consulting services to companies in the telecom industry in the

United States and the United Kingdom.$$ Due to its success, CMS

is hoping to expand its operations into other parts of

Europe.$$ Despite its large size, CMS currently uses a

manual$/$spreadsheet$-$based process for maintaining employee and

client data.$$ Management has now decided to implement a

company$-$wide application that will keep track of all of its

employees$$ hours, calculate employee payroll, and produce invoices

for clients based on hours worked by employees.CMS currently employs $1,500$ individuals $(900$ in the US and $600$

in the UK$)$ who serve as systems analysts, developers, managers,

testers, maintenance engineers, accountants, lawyers, and sales

representatives.$$The company also has more than $200$ clients in the US and

UKx.$$ Clients can have one or more contracts with CMS to

provide a variety of consulting services.$$ For example, a

single client might have one contract for maintenance of an

existing system and also have another contract $($sometimes called a

work order by the sales force$)$ for the development of a new

system.$$Some clients are billed based upon negotiated contracts, which

stipulate a pre$-$determined amount for charges $--$regardless of the

number of hours that employees actually work on the

contracts.$$ Such contracts are called $$fixed

price$$ contracts.$$ Other clients are billed based on the total

number of hours provided by CMS employees multiplied by a rate per

employee type per employee hour.$$ These arrangements are

called $$T&M $$ Time and Materials$$ contracts.$$ T&M

contracts specify a maximum of forty hours per week for which the

client is willing to pay.$$ Any amounts over $40$ hours per week

are not billable, but are considered discounted hours.For T&M contracts, the rate per hour for each consultant is

determined by the employee$$s level of expertise.$$ For example,

a client pays $$100/$hour for an employee who is at the level of

Systems Analyst I.$$ That same client pay $$250/$hour for an

employee designated as a Manager II$.$T&M and Fixed Price contracts are the only two types of

contracts currently used by CMS$.$All CMS employees must keep a record of the time they spend

working for each client on a weekly basis.$$ Because

employees can work for more than one client and perform different

functions for each client, CMS utilizes $$project management$$ to

keep track of employee assignments to client contracts.$$

Employees can be assigned to work on more than one project at a

given time.$$ In fact, it is not unusual for an employee to

spend time on two or more different projects within the same

day.Just as a client can have more than one contract with CMS$,$ a

contract can consist of more than one project.$$ For example, a

contract for the development of a new system could be fulfilled in

multiple phases.$$ Phase I could include implementation at one

client site using a group of consultants in close proximity to that

site.$$ Phase II could include implementation at a different

site with a potentially different set of consultants.$$ Both of

these phases are considered separate projects, even though they are

governed by the same contract.$$The number of hours worked for each employee on each project

must be recorded on a weekly basis.$$ Employees currently log

their time using an Excel worksheet.$$ An example of this

worksheet is presented below.$$ Notice that the employee$$s

supervisor is listed on the worksheet.$$ A supervisor is

currently required to approve his employees$$ timesheets by placing

his initials beside his name.$$Deliverable:For this assignment, you are required to create the GUI for a

timekeeping$/$payroll system for CMS$.$The system should first allow an employee to enter his name and

record the time he worked on each project for a given week.$$

Using the spreadsheet above as a guideline, the system must allow

the user to enter his name and the name of his

supervisor.$$ Next, the user must enter the number of the

week for which he is entering time.$$ Assume a maximum of $52$

weeks in a year.$$ Make sure the employee enters only a valid

week number.To record an employee$$s hours, the user must enter the name of a

client, a client$$s contract and a project.$$ For each of the

seven days in a week, the user must enter hours worked or check a

box that indicates the day is a weekend, a holiday, or a vacation

day.$$ If the employee fails to enter any hours for a day and

fails to check the weekend$/$holiday$/$vacation box for that day, the

system should warn the user that the given day is missing

information.$$ The system should also ensure that if any work

hours are entered for a day, the checkbox for that day should NOT

be checked.$$ Finally, the system should ensure that a user

cannot enter more than $24$ hours in a single day.$$ Once the

hours are entered, the user should be able to $$Submit$$ his hours by

clicking a button that will calculate his payroll information for

the week and display it on the same screen.Payroll information is calculated as

follows:All employees are paid for hours worked at a rate of $$15$ US

dollars per hour.$$ If the number of hours worked in the week

exceeds $40,$ the employee is paid time and a half for his overtime

hours.$$ For example, assume an employee works $50$ hours during

a week, he will receive $(40$ X $$15)+(10$ overtime hours X $(1\mathrm{.}5$ X

$$15))=$ $$825\mathrm{.}00.$ If an employee works less than $40$ hours in a

week, the system should make note of this fact in a label beside

the supervisor$$s name.$$ An example payroll calculation is

shown below:Payroll information for John Doe for the week ending
