System Sequence Diagram 5. Using the Activity Diagram above, produce a system sequence diagram, i.e. only include two swimlanes one for the actor (PSSM employee) and the other for the entire system as a system class object? Answers: 1. Data Flow Diagram Level 0 Diagram and Context Diagram Context Level Diagram: The context level diagram demonstrates that entire operational process for Professional and Scientific Staff Management (PSSM). The design context diagram allows the CEO or the member of the staffing agency in taking order from the clients and process the order into database. If the database accept the order of the clients then it request to pay to clients for the professionals or technical staffs. After putting information and payment by clients, an entire detail goes to the financial department of the company. In this context diagram, the process is represented by the oval circle. External entity for the business of PSSM can be the actor. They are able to receive the process as well as trigger the process. In the business process of Professional and Scientific Staff Management, there were two external entities. Following to round rectangular shape represented the external entity of PSSM Flow of Data was represented by the front arrow keys that connect the main process with the sub process. Data Flow Diagram: Above level 0 diagrams demonstrates that client can input their criteria into the automated information system. After getting the input from clients enquiry handling department schedule the criteria clients. However, this automatic system allows to take appointment from respected staffs or employees or professional that record stored in the record information database (Dennis et al. 2012). After taking the information about employees, enquiry handling department makes the evaluation of input method. Apart from that, the system is designed with the sequential communication and it creates a time lag in order to process the system seriously. The symptoms of design system automatically checked time to time (regular intervals). However, the forms that placed in left is originated as a automatic triggers and the entire process can get overlooked during the time of absence of people or when the people busy. The record information systems are very string and it is not affected by the feedbac k of clients or the process manager such as accounts department, enquiry handling department, etc. Moreover, the controls system of design data flow diagram supposed to generate result when it was executed (Kordon, 2013). The designed data flow diagram for Professional and Scientific Staff Management staffing agency is developed with too much form filling trays. It helps in minimizing error and the scope for future success. Apart from that use of too much form filling trays reduce confusion for users. However, the designed data flow diagram makes a very easy system to use and the foundation of design data flow diagram of Professional and Scientific Staffs Management produce the information and stored it into the database (Zhang et al. 2012). Thus it manages the entire information system process for Professional and Scientific Staffs Management. Use trays and system helps in generating automatic result in different ways as well as in different stages of processing. Apart from that, the designed diagram works in different locations based on geographic area. Designed DFD possibly derives the report of transaction and keep the record of transaction details in database. Furthermore, above mentioned DFD prevent the duplications of data or transaction details in database (Sandborn, 2013). The above DFD allows the member of enquiry department to advertise the potential employees of technical staffs to their clients. This recommendation with detail description helps in motivating customer and increased the satisfactory level. The functions of receptionists in this automated system help in active performance by the receptionist of PSSM. They provide the information to clients about available staffs in their agency and recommended for undertaking the appropriate employees by analysing the clients business activity (Berk, 2009). The designed DFD or automated system explains the entire operational process of Professional and Scientific Staff Management. 2. Use Case Diagram The aim of this use case diagram is to include the clients for selection of employees automatically based on their matching criteria and employees qualification. The design use case diagram demonstrates the detail description via different layers. The design use case diagram never repeats the scenario. The use case diagram allows the clients in subscribing their reviews because clients or customers of Professional and Scientific Staff Management staffing agency company has wide range of clients based on different locations. When clients subscribe their reviews the tracking system handling information and provide options to select the location to client (Sarma, 2012). Based on location, the payment options are also different. Therefore, the case diagram allows clients in understanding payment details in the designed system. Apart from that, clients can order for required employees and get opportunity for selecting the employees or technician that required for their business based on m atching criteria as well as qualification. 3. Domain Model Class Diagram The designed domain model class diagram explains that clients placed their order via the automatic system of PSSM. This diagram demonstrates that client have wide range of choice before purchasing a employees for short time project or technician for making a solution of their IT system. The use class diagram helps the company in generating unique ID for each payment as well as each order (Park and Rim, 2012). The system generate ID or complete the order process after getting information with detail description from the account department of professional and Scientific Staff Management. As soon as, details of payment get, payment department confirm the booking of technical staffs or employees for short term project. In the placed order box, clients can view the purchased order with detail description. In the order status box, customer can get the information about placed order such as shipment, delivery, handed to clients, etc (Qu, 2012). Apart from that the designed system facilitate s the company in linking the line services with the order specification of client. It indicates that, the receptionists of PSSM provide detail description to the higher authority of the company and engage or booked technical staffs or employees according to requirement of client. 4. Activity Diagram This activity diagram displays client order for the employees or technical staffs based on their requirement. However, if the selecting employees not available on that occasion one message display that selecting employee is not available at that moment (Choi et al. 2011). Moreover, client can shows the price of employees for contract basis into the display board and after selection of employees one form appears for input the payment details. After putting the payment details it shows waiting message due to verification of payment methods. If the payment price does not match with the selected employees price, it shows that payment amount does not match with the employees price. The design automatic system display to client the dispense amount and dispense staffs. 5. System Sequence Diagram This system sequence diagram allows the actors of PSSM to check the credit for purchased or booked employees for short term project or technician for resolving technical issues. The employees of PSSM can generate information from the stock inventory of design class objective about the engagement with other companies for project. Apart from that, CEO or the other member of Professional and Scientific Staff Management (PSSM) can get information from stock inventory about details operational process.
