Business process modeling can be termed as business process management and system engineering of the activities which helps in representing process of enterprise so that the current performance of the organization can be mapped. The functional flow-diagram is a multi-tier, step-by-step and time sequenced system functional and information flow diagram. The business process modeling concept was started in the late 1950’s and got famous in the system engineering concepts. Functional flow diagrams are the one of the most legacy business process modeling technique which is used in business process modeling. The modern functional flow diagrams are developed by the TRW incorporate which is an American defense-related business organization. After that NASA, used the business process modeling technique in order to visualize the events in flight missions and space. These diagrams frequently became the most preferable choice of the project managers and business analysts.
Functional flow block diagram
Functional flow block diagrams are useful to block diagrams which are created in order to analyse level wise progress , as in the case of the data flow diagrams that are currently being made by the project managers. This allows to recognize similar tasks, alsoit is useful when it shows consistent relationships among different entities of the project. Taking, for example, the way in which NASA used functional flow diagrams during space flight can demonstrate the best practical implementation of the functional block diagrams. It is used to characterize the entire flight mission on the basis of each level of involvement. Every part of flight mission can be easily visualized in the progress where various abilities that describe what each part does and what activities can hinder the dimension of flight. Each of them is divided again into sets of successive capacities. This allows designers to identify the requirements (Dam & Ghose, 2015).
The overall useful life cycle of the procedure and the degree to which the final product is acquired is represented with the help of functional flow diagram. In general, in most cases, it will be considered that main part of the procedures, i.e. scope and capacity is used to satisfy the work required. Furthermore, the procedure envisaged and reasonable wishes of procedures and their applications are discussed in business process modelling. The administrators (staff) must be taken into account and, if necessary administrator procedure can be carried into or from the staff preparing SOP if the procedure is planned effectively and all that should be sufficient for the proposed reason is met.
History of Business process modelling
In the year 1990s, the term "process" became another worldview of productivity. Organizations were encouraged to focus more on procedures than skills and strategies. The thought process which participates in a series of events in which organization is planning which include activities such as purchasing, delivery or requests for a return to transactions, etc. The usual demonstration instruments have been developed to illustrate time and costs, while modern devices focus on utilitarian exercises. These interdisciplinary exercises have expanded extensively in terms of numbers and meanings due to the development of a multifaceted nature and trust of the business in process modelling. The new techniques include the updating of business processes include progress of the business process and management of business processes. Furthermore, coordinating business organization, among others, "striving to improve the forms in relation to the habitual skills that comprise the organization".
In the field of software engineering, business process modelling can oppose the common software process modelling which aimed to practice software development. Furthermore, the latest implementation in business process modelling is achieved with the development of object-oriented approach. The object-oriented approach is inspired from the nature in which business specifications are called as object and collection of structure and business operations is called as a class. The first visual oriented tools for business operations is developed and implemented around 1995 which offer support to the data collection, data flow analysis, process flow diagram and reporting facilities.
Tools of the business process modelling
Business process modelling tools offer business users to model business operational process, implementation and execution. Along with this business process modelling, supports refine the executed data of the business in an efficient and effective manner. The tools of the business process modelling are divided into two parts such as modelling and simulation, and another one is the programing language. The modelling and simulation tools are referred to as use case diagrams, activity diagrams, lifecycle modelling language, subject-oriented business process management, ICAM definition and many others. Furthermore, programming language tools for business process modelling are used for providing programming interfaces for web-based services, application program interfaces etc. The business process execution language, XML process definition language and web services choreography description language is used by the business process modelling (Saini & Thiry, 2017).
Data flow diagram
The data flow diagram is a visual flow data diagram through a business process can be managed via a computer system. The data flow diagram helps in forming internal and external information of business procedure of stored. The data flow diagrams are constructed on the level wise architecture such as context, level 1 and level 2.
