User involvement in the processes of software development has proven successful in the past, but the definition of “user” has changed over the recent years. The term “user” has a broad and vague definition in software development as the user can be defined in many roles within the organization. In addition, there are many levels of software development, and the success that was once praised could have been misleading because of the level of participation that the user was involved in. Studies over the past four decades are consistently showing that user involvement has had a positive effect on the development process. On the other hand, there are some variances in the reporting factors due to a possible lack of information or the change in how most envision the role of users and stakeholders. This topic has recently attracted numerous interests as the modern day use of agile development and JAD (Joint Application Development) have become the leading methods that include user involvement in the software development process [1].
The process of involving users in the evolution of software has become a topic of interest over the past couple decades. Before mobile platforms and even personal computing evolved, users were mainly defined as software professionals. Today, users are just about anyone who has access to a computer or mobile device. This new influx of user involvement has prompted software developers to incorporate users in the development process more frequently. The question that most would like to see answered is how much of a positive impact can user involvement have on the development cycle and ultimately, how successful the final product is.
In recent years, a new method of software development known as HCSDLC (Human Centered System Development Life Cycle) has emerged to help developers deal with the influx of user-centered software. Mobile
Customer satisfaction is the important part in agile development and it is found by direct contact with the customers.
It is a requirement that every major software development and implementation project includes three key stakeholders. These are enterprise customer, system integrator and software vendors. Most failures of the systems are contributed by these three stakeholders.
It is well known that the team work is far better than performing a task individually. Such kind of practice plays a very important role in software engineering. A lot of things can be achieved together with the combination of diversified people, as they input different tactics and skills so that the main objective of a certain mission can be accomplished appropriately. Even though teaming up and working for a project is essential and helpful; there exist some issues that could bring interruptions and conflicts in the team.
Service user involvement and participation has become a standard principle in guiding social care planning in order to improve in the developing and delivery of service to meet diverse and complex needs in a more effective way. Key pieces of legislation states plainly that service users through a partnership approach should be enabled to have voice on how the services they are using should be delivered (Letchfield, 2009). The Scottish Executive (2006a:32) helpfully state ‘Increasing personalisation of services is both an unavoidable and desirable direction of travel for social work services. Unavoidable in the sense that both the population and policy expect it; desirable in the extent to which it builds upon the capacity of individuals to find their own solutions and to self-care, rather than creating dependence on services’
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
A User Contribution System engages users and facilitates their contributions towards creating value of a product or service to other users. These systems are extremely beneficial to companies that incorporate them int...
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).
Software development life cycle (SDLC) can be termed as a process of bringing ideas to reality in the creation of a software product with in the software industry.
Within the ‘Software Development Life Cycle’ or SDLC, are two well-known models; The traditional model, commonly known ‘The Waterfall Model’, and the more modern models of which we will be observing the ‘Structured Evolutionary Prototyping’ model. Through this I will show you that while both of these models have their own set of benefits and short comings, they each have their own place within the SDLC and that each is superior in their own area and should be used as such.
As part of developing the need in the initial investigation step in the systems development life cycles (SDLC) process, a constructive method is use case. Use case is a technique for capturing requirements with written scenarios in non-technical terminology that describe how a system interacts with a user or another system (University of Phoenix, Course Syllabus, 2006). There are two fundamental pieces, along with how they relate, to bear in mind: the actors and the goals. The actors are everyone and everything that will use (or be used) by the project progress reports, and the goals, which are what the actors want to achieve. The use case will describe the goals achieved by the actors who perform tasks (Carr & Meehan, 2005).
Brook’s paper “No Silver Bullet: Essence and Accidents of Software Engineering” presents how complex the development of a software is and its inherent difficulties. He brings out the accidental and essential difficulties we encounter in the process of software development. He identifies complexity, conformity, changeability and invisibility as inherent properties of any software whereas accidental difficulties are experienced during the development cycle/process. He suggests that being able to develop reusable software cuts down the costs and time as well as gives room for a wide variety of applications/functionalities across different platforms/ environments. Being able to balance and to bring best out of the resources that are available in terms of processing powers, hardware/software capabilities, personnel, budget etc., is very crucial for the success of software in the market. It is quite interesting and very relatable how the creative process of developing software in stages helps and (rather than just writing the code) motivates the software developers and design managers in coming up with new ideas during the iterations. Brook’s also mentions how high level programming languages, time-sharing and different development environments have affects on the complexity of software development process to remove accidental difficulties thus resulting in high efficiencies. According to him, fields like Graphical programming, Expert systems, Artificial intelligence though provide powerful insights, they have little to do with actual software development process to define its requirements or functionalities. He identifies how user can benefit from adapting an existing system to sol...
As more companies that are leading technology are transforming from the traditional waterfall development model to an Agile software methodology, requirements engineering provides a process for software engineers to understand the problems they need to solve (Martin, Newkirk, & Koss, 2014). It is of key importance to understand the customer 's wants and needs before beginning designing or building the computer-based solution, as developing a solution that ignores the customer’s needs provides value to none of the parties involved. Thus, the intent of requirements engineering is to produce a written understanding of the customer 's problem (Pressman, 2010). Work products that are available to communicate this understanding include user scenarios, function and feature lists, analysis models, and specifications. This paper provides an evaluation of requirement patterns, an assessment of problem solving techniques most effective, a descriptive explanation of the patterns that includes a visual taxonomy, and an explanation of how the patterns identified are related.
Human Computer Interaction is an emerging field that encompasses computer science along with cognitive science, psychology, artificial intelligence, industrial design and human factors engineering. A few decades back the field was confined to personal productivity applications. However, now it has diversified and includes aspects as varied as information systems, visualization, system development process and collaborative systems. The researchers in this field find novel ways and technologies that can facilitate better interface between humans and computers and hence lead to positive outcomes. On an individual level, I tend to figure out how people react to various things in any field, it’s like a hobby that has intrigued me for a long time
Over the last few decades the world has seen the likes of computing become more and more apart of daily life than ever before. It has allowed easier multitasking for business allowed the internet to rise and applications to do process never thought before. However Most People do not think about the work that goes into these applications, behind the scenes.
When working on software with a certain group of people, the programmer will tend to talk more on what they for the program. The programmer gets a list of things needed for the software. They test the software and then release to the group. This usually happens when the programmer work independently or a small business. In bigger corporations this will not be as likely.
