CMS Project – Phase I Instructions

Part A:

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 database that will serve all of its operations.

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. Each employee has a first name, last name, unique CMS ID, office location, email address, salary, title, level, and supervisor.

CMS has more than 200 clients in the US and UK. Clients are identified by various names by CMS associates. As such, they represent a source of confusion for the company. The legal department refers to clients by their legal names, while the sales and consulting departments refer to them by a more common name. One example is British Telecom. CMS’s legal team uses its full legal name “British Telecom, Ltd.,” while the sales force and consultants refer to it as “BT.” The accounting department uses a mixture of legal and common names to identify clients. Thus, to avoid confusion, both legal and common names must be available to all users. Data that must be kept about clients include client names, an address (city, state, zip, country), and contact information (discussed below).

Clients have contacts within their companies that CMS employees must utilize. For example, the accounting department must know a client’s billing contact in order to know where to send the bill. Maintenance engineers must know a client’s systems engineering contact to know with whom to speak when a problem arises. CMS’s sales representatives must know a client’s sales contact to determine who is responsible for the buying decisions at a client site. Although only these three contact “types” are currently used by CMS, it is foreseeable that additional contact types might be useful as the company expands into other parts of the world. Currently, a client has only one billing contact, one systems engineering contact, and one sales contact at any given time. This structure is not expected to change (that is, more than one billing contact per client as of a particular point in time is not anticipated); however, it is important to retain all contact information over time. That is, when one contact is replaced by another contact, it is essential to retain information about the original contact. For example, assume an invoice is sent to Contact A, who is later replaced by Contact B. If the invoice is lost, CMS must have an audit trail to show that it was sent to Contact A (who was the known contact for the client at that time).

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 often specify a maximum number of hours for which the client is willing to pay. CMS managers must ensure that when these maximum (cap) amounts are exceeded, the clients are not billed for such additional 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 might pay $100/hour for an employee who is at the level of Systems Analyst I. That same client would pay $250/hour for an employee designated as a Manager Level II.

Although T&M and Fixed Price contracts are the only two types of contracts currently used by CMS, it is likely that other types of contracts will be used in the near future.

All CMS employees must keep a record of the time they spend working for each client. 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 many different projects throughout their tenure. They also can be assigned to 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. Likewise, projects can consist of many different employees. Project assignments change over time. For example, Employee “A” may work on Project “X” during January, and, in February, that same employee may be reassigned to Project “Y.” It is important to maintain records of the dates for which each employee is assigned to each project. Additionally, each project has a manager who oversees its progress and ensures that contracts are fulfilled and profitable (e.g., U.S. project managers try to prevent hours worked in excess of the maximum allowed by a fixed price contract).

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. To further complicate matters, if such a contract specifies a maximum number of hours for overall implementation, the project managers of each project will have to agree how to split up the cap amounts between the two projects and maintain appropriate data about the split.

The number of hours worked for each employee on each project must be recorded on a daily 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. This supervisor may or may not be the same person as the project manager. Each employee is assigned to one supervisor, and each supervisor manages one or more employees. The concepts of supervisor and project manager have completely different meanings at CMS. A supervisor manages an employee with respect to evaluations, vacation requests, raises, etc. A project manager manages a project, allocating the time of employees assigned to the project. A project manager is not required to sign off on an employee’s timesheet. A supervisor, however, is required to approve his/her employees’ timesheets by placing his/her initials beside his/her name.



Part A: Deliverable

For this phase, you are required to create an ER Diagram that will facilitate the development of CMS’s company-wide database. It must be created using ER Assistant and include entities and attributes, relationships, and accompanying notes. You must take a screenshot of your ERD while it is displayed in ER Assistant and paste the screenshot into a Word document. Make sure that the ERD fits on a single sheet and is legible. Accompanying notes must be included on a separate sheet of the document. Name this Word document “CMS Project Part A – your last name followed by your first initial.”

Example: CMS Project Part A – SmithJ.doc

The scope of the database includes all entities referenced above. The first goal of this phase of development is to support a timekeeping system that will replace the spreadsheet process illustrated above. Note that you will not actually create the timekeeping system. You are responsible only for designing the database that will be used by the system.

Part B: Background

After much deliberation, CMS has decided to broaden its operations by expanding into various parts of Europe and also Canada. It plans to recruit employees from Canada, Italy, France, and Ireland. Each of these countries offers different benefit packages. Presently, under the manual spreadsheet system, human resource personnel have to maintain only two types of benefit allotments. In the newly expanded company, this manual process will be unmanageable.

The following table lists the different benefit packages in each country. Some characteristics are unique to each country while others are unique to a region.

In the same manner that employees must track the time they spend working on projects, they must also log the days they use as holidays and vacation. Below is a sample timesheet for recording benefit time taken. Note that this benefit section exists on the same timesheet that is used to log hours to projects, but benefits are not related to projects.



In addition to the need to accommodate benefit tracking in the new database, a change has occurred since the last iteration. In Part A, CMS stated, “a client has only one billing contact, one systems engineering contact, and one sales contact at any given time. This structure is not expected to change (that is, more than one billing contact per client as of a particular point in time is not anticipated).” Recent developments from a newly acquired client have caused this assertion to no longer be true. France Telemobile, Inc. is a new client in France and has three different systems engineering contacts to support its one contract with CMS. Thus, a change in initial design is required.

Finally, CMS is implementing two new types of contracts, maintenance and license, to be added to its list of possible contracts.

Currently, maintenance is included as part of an initial work order. In keeping with the rules of accounting and revenue recognition for software providers, maintenance is an important feature of a contract and has special rules that affect how much revenue can be recognized for licenses. To simplify its procedures, the company will be issuing separate contracts for maintenance to clearly distinguish between license revenue, which can be recognized at the time of system delivery, and maintenance revenue, which in most cases must be recognized over the duration of the maintenance agreement.

Many of the features of CMS’s custom work orders have evolved into a standard set of templates that will be sold as a package to other companies to expand CMS’s client base. Therefore, the company has created various products that incorporate the most widely used features of its custom development initiatives. The products are called TeleTrak-BP, TeleTrak-FM, and TeleSource. Each product will be sold as an out-of-the-box solution to tracking usage and subscriptions in the Telecom industry. Each product will be sold under a license contract. Presently, a license contract will be issued for exactly one product, but it is possible that a license agreement will be written in the future that will cover multiple products as new products are developed.

Part B: Deliverable:

Using ER Assistant, modify your original ERD to accommodate the requirement to allow more than one instance of a given contact type per contract. Also, include new entities and relationships to support benefit tracking in all countries. Depending on your initial design, you may or may not have to modify your ERD to accommodate the new contract types (License and Maintenance). You will also have to account for the introduction of products in the business model.

In a separate Word document, take a screenshot of your revised ERD and paste it in. Include accompanying notes.

After completing your new ER Diagram, convert the diagram into tables with primary keys and foreign keys as appropriate. Use SQL Server to create your tables. Be sure to enforce referential integrity in your CREATE TABLE statements using “on delete,” “on update,” etc., where appropriate.

As in Part A, your ERD screenshot must be able to legibly fit on a single sheet in the Word document. To receive credit for your table conversions, include the SQL queries used to generate the tables and paste them into your Word document. Also execute the following command for each table and include results in your document: exec sp_help [table name]

Name this document “CMS Project Part B – your last name followed by your first initial.” Screenshots are required each SQL, DML, DDL, and DCL statement for a grade to be given. Note: 1 screenshot is not the idea; however, multiple screenshots along the way is the goal.

Using the link provided in Blackboard, upload your 2 documents for phase I of this project by 11:59 p.m. (ET) on Monday of Module/Week 5.
