Functional Decomposition Diagram

Every company will focus on supplying a service, product, or both. How and where the product is made plays a crucial role in the company’s success. In order to help visualize how the products are made process maps are formatted. These process maps can help to identify areas that need improvement. In order to implement improvement, process development will be implemented. The form of good that a company supplies is also important and to ensure that the best product is distributed product development is conducted. Target Corporation is a complex company, which provides consumers with their necessities.

In all companies there are many different tasks which need to be carried out regularly, in order for the business to reach its aims and objectives. Stock needs to be brought, the bills and finances need to be controlled, and customer service issues dealt with and so on. In a small organisation one or two people may do all the jobs, whereas in a large organisation people have to be specialized in many different individual tasks. In a large company it is easier to identify the separate functional areas, because groups of employees would work together in departments. Each department carries out its own individual tasks to relate to their specific area. The main purpose of functional areas

Within any business there are the organizational functions that can create the type of structure an organization will have. A business's functions are the things it does. Production, sales, and marketing are a few examples Chick-fil-A has within the company. The organizational structure defines the relationship and interactions between the different parts of the company, and identifies how the chain of command runs through the different levels. When money is earned at a fast pace, it opens doors for the company to expand. As the company grows, they begin to hire more employees and they offer new products.

In order for IT System to become active first Computer Programs and Programming must be put in place. Computer Programs and Programming are simple terms an executable set of commands for the computer to perform. A process is an actively running program which may or may not is running in the background. A program running in the background is one that the computer user may not be aware of, but it may be providing useful services such as an ability to connect to other computers. It reads and executes program instructions, performs calculations, and makes decisions (slideshare.net).

Decomposition is another tool that will be used to break the requirements documentation down into identifiable work portions, or a work breakdown structure (WBS). GenRays resources will be assigned to the project team based on their work experience and general project team experience to effectively perform the necessary work in the WBS.

As a process executes it changes state. The state of a process is defined by the current activity of the process. A process may be in one of the following states shown in Figure 1

It demonstrates the workflow behaviour of a system which describes the state of activities by showing the sequence of activities performed in different order. The diagram has branches and forks to describe conditions and parallel activities.

As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary (Dennis, Wixom,

This model demonstrates the data attributes logical entities and relationships between these entities within a business function. It also helps to create the physical data model. Moreover, it shows more details while integrate business logic and business rules. This model is used to describe the domain concept and their relationship of the domain problem.

These three function groups are categorised based on their fundamental and immediate functions required to carry on the primary and ancillary (supportive) business processes. These three groups cannot operate independently, as they are interdependent for execution of their respective tasks or

These different functions have their own roles and work together to optimise performance. Different functions work together by communicating with each other and sharing information so that everybody has relevant up to date information on the company’s plans and tenants issues. Each function carries out its own

Data Flow Modelling – This is the process of modelling and recording how data flows around a system. A Data Flow Model is made up of connected Data Flow Diagrams (DFD) which are supported by appropriate documentation. DFDs represent the processes and functions within a system (activates that transform data from one form to another), data stores (file storage, external entities (things that send data into a system or receive data from a system) and finally data flows (show the flow of data around the system).

Formulating a network diagram, likewise alluded to as a logic diagram, in order to comprehend and envision how each task will continue is an extraordinary path to begin. It is a basic idea within project management planning that is effectively utilising as a part of application, commonly used as a part of assembling commercial enterprises, and also to outline and comprehend work processes are what service industries requires. It distinctively shows the rational rules for influencing tasks. (Holland, 2014) The development of the network diagram by incorporating the project team acquires an agreement of comprehension of how the undertaking ought to be accomplished. Nonetheless, giving a discussion to testing acknowledged

When we create a product or provide a service, such as developing software, writing a report, generate a business analysis, we always follow a series of ordered steps to accomplish a set of tasks. To correctly produce an intended output, the tasks must be completed as specific order, we can consider a set of ordered tasks as a process, involving activities, constraints, and resources. When the process involves the building of some

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
