Disadvantages Of User Centered Design

Developing software is far from an exact science and without a structured system to guide the process a project is likely to fail. Defining and adhering to a Software Development Life Cycle (SDLC) early in the project will help to guide the development of a new information system. In addition to having the structure for the development team to work within a defined and agree upon SDLC will help to set the proper expectations for deliverables with the stakeholders and customer(s). Smith Consulting has been given the task of creating a Frequent Shopper program for Kudler Fine Foods. As a result Smith Consulting needs to decide on which SDLC will work best for this project. In addition to selecting a SDLC to use Smith Consulting will

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. ("Mind Tools", 2012).

The users are obviously important because they will be using the system and the IS are only designing the system. The goal is for the system to be designed to be as easy to use as possible for the user. The next key factor in any project is planning, the planning factor is the amount of preparation that will be performed for the IS requirements. A good work plan and schedule will help the project flow much easier and be successful ("Tech Republic", 2013).

Team Mates as you know that we have chosen the Requirements in System Development Life Cycle, so have came across the following stages in the Requirements in my research which will be posted below specifically under their requirements.

As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. Since software is needed almost everywhere today, its development is a highly intelligent and precise process, involving various steps. Known as software development life cycle, these steps include planning, analysis, design, development & implementation, testing and maintenance. These steps go on to create the perfect software for clients. ”

Design activities are closely interrelated and generally all done with substantial overlap. “During design, it is often necessary to verify the correctness or workability of the proposed design. One important verification method is to build working prototypes of parts of the system to ensure that it will function correctly in the operating environment.” Every system must have sufficient controls to protect the integrity of the database and the application program. These controls should be integrated into the new system while it is being designed, not after it has been constructed (Chapter 2, 2004).

Questionnaires are also disseminated to gather opinions from end users. In addition, analysts will observe the way the current system is used to perform day-day activities, and collect data. Analysis will be conducted on the different types of documentation used to understand certain rules, processes and procedures. Finally, a joint application design (JAD) can be conduct by way of a meeting with end users. The purpose of the JAD is to gather requirements that all parties can agree on (Valacich et al,

The development of information systems requires cooperation between end-users and IS specialists. End users provide the business needs and requirements of the system. The people who will use the system the most know what functionality they require. For a large facility, there may be many departments

It has been observed that in software development, change is unavoidable and must be accommodated for in the life cycle. A number of alternative process models have been introduced in order to attempt to fix the issues in the Waterfall model. An early modification to the standard Waterfall method introduced prototyping as a feedback and discovery mechanism to identify misunderstandings and omissions early on in the process (Neill, 2004). Other process models attempted to further get rid of the risks of misunderstandings by breaking down projects

User interface design is the design of user interfaces (UI) for machines and software, used on computers, smartphones, and any other electronic device. The goal of a user interface is to maximize a user’s ability to access all necessary components of the intended application or website with less effort exerted by the user; as a developer you want to create something beautiful that somebody with any previous experience of interfaces would be capable of using. Using an interface should be an enjoyable experience, the user shouldn’t be stressed out or annoyed by UI, and its inability to present the necessary information in an aesthetically pleasing and efficient manner. There are no steps to design that are set in stone, but crucial things that should be considered are:

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

The System Development Life Cycle Methodology is indeed excessively formal and rigid and should be made more flexible and unstructured. This stand is taken to agree with the notion that the system development life cycle model is formal and needs to be made flexible. The position that the System Development Life Cycle methodology is excessively formal and rigid has been taken due to the below reasons.

End-user involvement is important because it determines the success of the HMIS. If there is no end-user involvement then the success of HMIS will be short and will not be able to continue into the future. In addition, when there is end-user involvement then the implementation of HMIS will be smooth and effective. When users are involved, then the users will make an effort to understand the system and to help others out when it is needed. For instance, when a nurse is confused about how to input something into the system then they can ask fellow nurses. However, if nurses do not want to understand the system then it will be difficult to help each other out. End users can be more involved in the process by making the user feel satisfied with

Without all the stakeholders being involved in the development process, their specific requirements and needs cannot be met. User requirements can be achieved by utilizing a variety of information gathering techniques to understand current processes and what is needed out of the new system.

In software development, there are various types of methods that developers follow in order to produce valuable software. From the many types of methods that exist today, the industry standard that is mostly followed today is the software development lifecycle (SDLC). The SDLC is a process that software development companies utilize in order to design, develop and test software during production. Within the SDLC, there are different test models that developers can utilize based on their business and development requirements. Currently today, the most common models include the waterfall, iterative, spiral and V-model. Regardless of the model that a developer decides to utilize, all the phases will be the same, which would begin with the first step and that is the requirement gathering and analysis phase.
