In current era use of computers and machines are become vital in daily life. To operate these machines, we need to give them instruction of doing some work in specific format which is called software. So, when a problem arises or identified and one want a solution by using machines, need of new software arise. And thus, a software development life cycle starts. To make this life cycle more efficient and accurate, different SDLC model and software development modeling techniques exist. Here in this research paper we will discuss software modeling techniques. The term “model” is derived from the Latin word modulus, which means pattern, measure, and rule. While a modeling language is any artificial
A profile allows UML to be extended for use with a particular programming platform or to model systems intended for use in a particular domain. A profile extends the UML to allow user-defined stereotypes, meta-attributes, and constraints.
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.

This way the IT department can understand what the higher level and lower level employees need for system stability and a better graphical interface. Another plan of action would include the method of Systems Development Life Cycle or SDLC. The phases of this method are planning, analysis, system design, implementation and operation. First we must plan on what exactly we are trying to accomplish. We know we need to upgrade the Riordan Manufacturing system. Next we must analyze the system and look for problematic errors. A project proposal can be essential to launching a system analysis (Farah, 2013). These are things to keep in mind: understand the business situation or problem, understand the significance to the problem in the organization, think of alternate solutions, the use of computer information systems for solutions, find people interested in the solving the problem (Farah, 2013). This plan is used to decrease redundancies, errors, and increase security. Finding all the weak spots in the company will help in the improvement of integrating an updated efficiently functioning system. Feasibility is important to account for when upgrading the system. Integrating a CRM will help to work with customers and understand their needs and wants to benefit the company and the relationship with their customers. Designing the system will involve knowing what kind of software is needed to store and
The 2167A specification focuses on documentation rather than on a software engineer development process. If the organization that intends to meet the requirement that was on the documentation it need to employ some relatively confined process that befit the documentation requirement. This paper explores the use of process/workflow models to represent the software
UML is powerful modeling language by which we can develop many diagrams which are user ready.UML can be used in web and commercial applications etc.UML is used to visualize, construct and to make a note of the software systems. In the beginning it was only used for the object oriented documentation and it can be also applied in the visualization of certain systems for elements such as discrete components in a system and their interaction and user interaction. The UML contains many diagrams which are used to envision a system architecture. In UML the diagrams are divided into two types mainly1)Structural UML diagrams and 2)Behavioral UML diagrams .
The Enterprise workflow process starts at the status of “Enter”. This is a system status that is invisible to the user. The user is automatically advance to “New” for standard workflow or “Technical Analysis” for maintenance workflow. Under the “New” status the change request is imported from

This is The 4+ 1 Model of a systems architecture in year 1995 the person name called Philippe question developed a model that lets architects break down and look at a system according to five different views and this called the 4 +1 model. When you’re trying to look at something a large and complex as an entire system architecture it’s useful to be able to break down the hole in two sets of related parts you can use the 4+1 model to understand the role that each kind of UML diagram plays in the model that you’re creating as a whole as follow-
Workflows are tools that manage personal, office, department or an entire organization's processes. A SharePoint workflow is an automated flowchart that takes a lot of the effort, guesswork, and arbitrariness out of your regular work processes and makes it simpler for you to streamline your tasks. It is most useful in automating existing conceptual or manual work processes of the company and reducing human dependence on enterprise as far as possible.
A software development methodology is a structure imposed on the development of a software product. It is used to structure, plan and control the process of developing an information system including procedures, techniques, tools and documentation aids. A wide variety of methodologies have evolved over the years, majority aggress that all these methodologies are distinguished into two categories – Heavyweight or Lightweight. Heavyweight methodologies are also known as traditional methodologies which approach system development with standard, well-defined processes such as Waterfall, Spiral and Unified Process. Lightweight methodologies
One commonly-used business process methodology is that of the Systems Development Lifecycle (SDL). The steps of the method involve: defining the components of the proposed system; determining its requirements (interviewing users, determining existing processes); designing the system components (determining specifications and job definitions); implementing the system (building, testing, and/or converting the existing system) and then maintaining the system (by fixing failures and quality monitoring) (Noe 2010: 18).
In Object-orientated approach methodology, a system is viewed as an object (Govardhan & Munassa: 71). This approach intergrades data and processes into objects. It emphasizes the construction and testing of object models. This technique uses UML diagrams such as Communication Diagrams, which show the relationship between objects, Development Diagrams which show how a complete system will be deployed on one or more machines, the Class Diagram and Sequence Diagram.
Project methodology provides the Information Technology Services project teams with group of rules to manage projects. Methodology is a tool provider to make every one 's job easier, mainly who manages the project, which contains the description, steps and templates to various project activities that require delivering successful projects. Project Management Methodology is a factually defined sequence of logically related practices, methods and processes that determine how best to plan, develop and deliver a project throughout the continuous implementation process until the completion. It is a scientifically-proven that systematic and disciplined approach project execution, design and completion of project. A methodology provides a skeleton for describing every step in depth, so that a project manager will know what to do to deliver and implement the work according to the budget, schedule and client specification.
