Using Microsoft® Visio®, create a 1-page UML-based diagram that depicts the process flow for at least four design classes based on the user stories created in Week Two.

Write a 1-page narrative explaining your UML-based diagram, including:

• A description of the processing flow within a specific scenario
• A description of the static view of the process
• A description of the functionalities/attributes included in the process

Value Chain System User 1: Inventory Management
Required Output
The system will be utilized for various functions within the organizations. It will
therefore provide output requirements for different organizational needs depending on the
department within which it is being utilized. Various output devices such as printers will be
strategically placed at such point as the general management and finance office where daily
reports and other firm reports will be printed out.
Features
The hardware and software components that constitute the system will differ depending
on the department within which the systems are being used (Lampson, 1983). The system will
consist of a major server that acts for storage of most of the information and data to be utilized
within the organization. Moreover, a backup database will be used for storage of data which will
later be retrieved in occurrences where data and information is lost.
Connection to a Local Area Network and a Wide Area Network will be essential in order
to facilitate connectivity of different systems components and departments (Coronel & Morris,
2016). Moreover, the need for the company to operate internationally and meet other enterprise
needs will require sharing of information and data over the internet.
A documentation of the system design will be important in order to facilitate future
modification and upgrade of the system. The design process requires a number of physical and
logical choices to be made in order to ensure that detailed attributes are generated for the VALUE CHAIN SYSTEM 3 database entities. For effective implementation of the database structure, domain knowledge and
understanding of the database requirements is the key to the design of the database structure. A
number of processes are usually recommended during the design of a database. They include:
requirement analysis, conceptual database design, and choice of the DBMS, data model
mapping, physical design and implementation (Haithcoat, 1999).
The data to be stored within the database should be identified prior to the design.
Requirement analysis will therefore be done in order to identify the database expectations that
ought to be put in place. This identifies the data types, tables, forms, queries and reports that
should be configured within the database (Coronel & Morris, 2016).
Functionality
Considering that the system is to be utilized within the same organization. Most of the
modules will be interconnected in such a way that allows interaction of different entities. There
are different departments within the organization and this call for an integrated regulatory
boundary to facilitate data security in terms of integrity, completeness and confidentiality. The
system may be composed of a number of programs depending on the types of information and
data being involved within the line of communication. The study aims at providing
recommendations on the process that would be used during the design of applicant database in a
small recruitment firm.
User 2: Staff Management
Required Output
This system should provide details about the staff present in the organization. When the line
manager enters the staff details into the system, it should display the following: VALUE CHAIN SYSTEM
1.
2.
3.
4.
5. 4 The login time of the staff member
The logout time of the staff member
Joining date
Department in which he/she is posted
Designation Features:
The system should be able to manage all the logs related to a staff member in the organization.
The system should be connected to the WAN and also to the LAN.
The system should be accessible only to the authorized individual but not to all the staff in the
organization.
The data of the staff members should be stored in a database.
Functionality:
The staff management system should function as follows:
1. It should connect to the LAN and if required WAN to get information from other
departments and branches.
2. The system should store in the database all the staff log in times and logout times.
3. The system should contain an interface that connects it to other systems such as payroll
software etc. in the organization.
4. The system should have a GUI for easy understanding and should be user friendly. User 3: Staff Payroll
Required Output:
The staff payroll system should provide details about the staff payroll. VALUE CHAIN SYSTEM 5 When the staff ID is given as input to the system it should display the following
1.
2.
3.
4.
5.
6.
7.
8. The name of the staff member
Date of joining of the staff member
Designation of the staff member
Number of days present in the month
The allowances given by the organization
Deductions if any
Total salary to be paid for the month.
Additionally, a pay slip has to be generated by the software that can be given to the staff
member later. Features:
The staff payroll system should have the following features:
1. Availability: The system should be available when it is required.
2. Reliable: the system should be reliable enough so that all the payroll calculations and
values are accurate.
3. Secure: The system should be protected by strong password so that cannot be accessed by
all the users. Functionality:
The payroll system is expected to calculate the actual salary of a staff member when all the
details of the staff members are entered.
The payroll system should also manage all the pay roll related information and provide pay
slips to the staff members.
This system has to be protected so that only authorized persons can view and make changes
to the system. VALUE CHAIN SYSTEM 6 All the information can be stored in a database that has to be secured from unauthorized
access.
User 4: Network management
Required Output:
The system has to show the network components and the devices that are connected to the
network.
The software also has to show the traffic flow of the packets if required.
Features:
The system should have the following features:
1. Availability
2. Secure
3. Reliable Functionality:
The system must keep track of all the devices in the Local Area Network of the organization
It should be connected to the internet or the WAN.
It should also analyze the traffic that comes in and out of the system.
It should contain a database that stores all the details of the devices of the network. VALUE CHAIN SYSTEM 7 References
