Object And Process Modeling, And Stragies For System Analysis And Problem Solving

Project scope defines the goals of the project and the budget of both time and money that has been allocated to achieve the objectives. For the best results to be achieved, both the definition and the allocated budget must be precise and detailed. A good process scope document will define specifically the tasks to be completed or the delivered results. The project scope is important because it will define the specific date for which the deliverables

Another way of successfully gathering information is by building a prototype or model of the system, so that users can test or get an idea of what the finished product will be like. With this they can determine issues, problems, or inconsistency with the system. Another important part of gathering information is organizing it so that it can be understood and put to proper use. I propose categorizing the requirements into functional requirements, operational requirements, technical requirements, and transitional requirements. The functional requirements define how the user thinks the system is functioning overall, the operational requirements define what background processes need to be executed in order for the system to work optimally over a period of time, the technical requirements define what technical issues that must be addressed in order to successfully implement the system, and the transitional requirements define the processes or steps needed to implement the system smoothly and successfully.

Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e. workflows). Activity diagrams show the overall flow of control.

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,

A project scope is a way to describe the major deliverables of a project and this includes key milestones, high level requirements, assumptions and constraints. A projects scope is a useful way to make decisions for the future of the project if changes are needed. The projects scope also defines boundaries of a given project and it clarifies what can be delivered and what is expected to be delivered ("Match ware", 2013). The scope explains the boundaries of the project and the responsibilities of every one working on that project. This helps who ever is working on the project by defining guidelines and helping them to remain focused. The projects scope is a very important part of the SDLC because this serves as a manual for how the project will be completed including important details, deliverables, tasks, costs, and deadlines.

Process Flowchart - The process flowchart is a description of how the various processes of the ISO 9001 QMS interact with each other. The process flowchart is required in ISO 9001:2008 section 4.2.2.

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.

A class is like a cookie-cutter in that it has the power to create multiple items that are alike in some ways: they all have the same number and type of fields, while their values can differ. You can compare this to all cookies having the same shape, but it is unclear how the differences between individual cookies map to the differences between objects that are class-mates; in my mind, two Cartesian coordinates with different X and Y values are much more different than similar, certainly much less alike than two cookies with the

Logic models represent a visual way of expressing the rationale or thought behind a program. Two other forms of expression may help concurrently support the development of a logic model, or accompany the model if it is to be communicated through written materials.

“A logic model is nothing more than a concept map that visually describe the logic of how your program is suppose to work” (Grinnell, Gabor, Unrau, & Grinnell,

A comprehensive project scope analysis serves several benefits that permit a company to guide the dream of a project to a successful completion.  One benefit is transforming the idea of the project into a working concept.  Once the concept is developed, project details can be mapped out.  Scope analysis outlines each step of the project in a detailed manner.  The primary benefit to this is it aligns the project so that the final product will be consisted with the original goals/objectives.  By outlining each step, scope analysis increases the likelihood that the project will stay within budget and time constraints as well as meet predetermined specifications and quality parameters.

The purpose of this report is to give information on the subject known as Logical reasoning and its use in Computer Science and computers in general. A historical background behind logic and Logical reasoning is firstly given, followed by an overview of the modern subject and the types it’s divided into. The types are then explained. The overlap between the field of logic and that of computer science is also given an explanation. The report ends with a brief overview on the subject and its tie to computer science and computing.

“A Business Process Explorer: Recovering and Visualizing E-Commerce Business Processes” is a research paper developed by the author: Jin Guo, King Chun Foo, Liliane Barbour, and Ying Zou. The focus of this paper is a business process and how it affects e-commerce systems. Business process can be defined as an assortment of linked, designed actions or responsibilities that are linked together by control flow foundations. E-commerce uses business processes to systematize the day-to-day work flow of an organization.

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).

The Unified Modeling language (UML) is defined in the Software Engineering as a form of defining the design of the system. It is a way to envision the system architecture in the form of a diagram. The paper discusses about the genesis of UML modeling and the forms of diagrams which are used in the UML modeling based on the survey conducted on various employees based on their skill set and level of experience in the software engineering field. Now we will go through each aspect of the UML modeling and try to derive conclusions on how far was UML modeling has been able to penetrate into day to day activities of this field and also discuss about the complexities associated with each components of the UML modeling as well as pros and cons.
