User Involvement, Challenges And Roles

For decades many information technology systems have failed to deliver the benefits expected by the users of the System. Insufficient user involvement in the design process is mentioned as a main factor contributing to this underperformance between what was expected of the system and what the system is in reality. They are so many System development methodologies but almost all approaches to system design / development involve users in the design process. The difference between the several approaches in system design lies in the degree to which users are able to influence the system design, “e.g., with SSADM, Learmouth and Burchett, Structured Data Analysis, users ,etc. are involved as providers of information to the project team since

Throughout the construction and planning phase the cost raises which result in extreme recession of money to the builders.

Key Element 1 – Scope. The most common risk associated here is scope creep, or the continued addition of new aspects to the scope. Scope creep can come from both external stakeholders and internally from well-intentioned project team members. While the team members may have good intentions with looking to improve a certain deliverable, this is dangerous because it can cause a project to slip months behind. These internally generated changes may bring

Due to lack of ownership the project is seen as burden because everyone is concerned with their own segment.

To be successful, projects need to develop context appropriate solutions informed by user needs. This implies including all user groups in planning, development, implementation and assessment; developing projects in an iterative mode. Furthermore, solutions need to be designed with the existing workflows in mind and plan for organizational adaptation. Finally, the design needs to be sensitive to, and

Five Methods for Identifying System Requirement and How They are Applied in any System Development Venture

User centred (UCD) is an approach that supports the entire development process in which a product is developed for the end users needs, not a product that is going to force the end user to change he’s actions to use the product. The users needs, wants and limitations are a focus at all stages within the design process and development lifecycle. Using the UCD methodology optimizes the final product for the end user. Typical UCD activities are broken down into four phases in the development lifecycle: analysis, design, implementation and launch.

Requirement engineering is the process of determining user’s need for a new & modified product. These features, called requirements, must be quantifiable, relevant and detailed. In software engineering, such requirements are often

Off-Specification: a non-forecasted discrepancy between a product or aspect of the project from their planned description

End users are the most important of all throughout the project. They are the most powerful influencing factor and that power might work for or against of a particular project. End users are the party who will be using the system when the project is finished. The main project deliverables like the system, and manual

The traceability of requirements is the ability to easily read what happened and what it is supposed to happen to something. Requirements traceability is to document the lives of the requirements. It must be possible to trace their origin to each requirement and each changes affecting them; requirements must be documented for complete traceability. The requirements often come from various sources, such as the marketing team, customers or users. All these people have needs for the product (or system). The project stakeholders express needs that are formulated in the

Also the overall cost of the project may have not been accounted for properly when the budget was originally developed and set. Meeting a projects budget, time, and user requirement takes the help of many to accomplish. The importance of meeting all these dynamics are vital to the success of the project. It important to be able to meet these constraints and overcome them.

This paper presents an overview of software systems requirements engineering (RE).The requirement engineering is the process of eliciting individual stakeholder requirements and their needs and evolving them in depth. And then granted requirements is documenting in a form that is responsive to analysis and communication and specified that they can serve as the basis for all other system development activities. This research paper provides a wide-ranging and well-structured introduction to the fundamentals, principles, and techniques of requirements engineering. In this paper they presents agreed techniques for eliciting, negotiating and documenting as well as validating, and managing requirements for software-intensive systems. The various phases of the process and the techniques are demonstrated using numerous examples and their work in industrial collaborations. Their presentation aims at professionals, students, and lecturers in systems and software engineering development. The Professionals people such as software architects, project managers, and software engineers will profit in their daily work from the well-presented mixture of validated measures and industrial experience. Students and lecturers will appreciate the complete description of sound fundamentals, principles, and techniques. It provides one of the clearest definitions of RE: “Requirements engineering is the branch of software engineering concerned with the real-world Goals for, functions of, and

In the design phase, the users works closely with the system analyst to develop models and prototypes that define the systems processes and functions. The development of the user design is an ongoing process that enables the users to make changes to the model until the final product is functional and meets the requirements of the project.
