Order now Introduction What exactly is global warming and why is it worthy of consideration? Global warming is the scientific phenomenon linking an increase of the average earth temperature because of a trapping of radiation within the earth like a greenhouse. This has been a natural phenomenon throughout the natural history of the world but it has only become a problem in the last few hundred years because of an anthropogenic increase in greenhouse gasses. Causes This essay on global warming needs to look at the causes of the problem.
Usage-Centered Design UCD The vast majority of agile projects are teams of less than ten people, are co-located, have direct access to stakeholders, have access to inclusive modeling tools such as whiteboards and corkboards, have their own development machines, and have access to the development tools that they require, including testing tools.
Having said that, some agile teams are very large upwards of several hundred peoplesome are dispersed geographically, and some do not always have easy access to stakeholders Eckstein Although most agile teams take an test-driven development TDD approach where they write a unit test before writing just enough production code to fulfill that unit test, they typically do not have access to UI testing tools.
Furthermore, they rarely have access to a usability lab, so in this respect agile is little different than traditional development.
Figure 1 depicts my rendition of a generic agile SDLCwhich is comprised of six phases: Although many agile developers may balk at the idea of phases, the fact is that it's been recognized that processes such as XP and DAD do in fact have phases.
Let's consider each phase in turn: The first week or so of an agile project is often referred to as "Iteration 0" or "Cycle 0" cycle is an alternative term for iteration.
The goal during this period is to initiate the project by garnering initial support and funding for the project; actively working with stakeholders to initially envision the requirements of the system at a high-level; starting to build the team; modeling an initial architecture for the system; and setting up the environment.
During development iterations agilists incrementally deliver high-quality working software which meets the changing needs of stakeholders. During the release iterations s agile practitioners transition the system into production.
The goal of this phase is to keep systems useful and productive after they have been deployed to the user community. The fundamental goal is to keep the system running and help users to use it.
Eventually your solution may be removed from production, perhaps because it supports a line of business your organization has exited or because it has been replaced by a more effective solution.
Because the agile SDLC is highly collaborative, iterative, and incremental the roles which people take are much more robust than on traditional projects. In the traditional world a business analyst created a requirements model that is handed off to an architect who creates design models that are handed off to a coder who writes programs which are handed off to a tester and so on.
On an agile project, developers work closely with their stakeholders to understand their needs, they pair together to implement and test their solution, and the solution is shown to the stakeholder for quick feedback.
Instead of specialists handing artifacts to one another, and thereby injecting defects at every step along the way, agile developers are generalizing specialists with full lifecycle skills.
More importantly, from a user experience point of view, they take a very different approach to modeling and t esting than traditionalists do. User Experience UX Activities Usability is a quality attribute of a system which encompasses learnability, efficiency, memorability, error recovery, and end-user satisfaction Neilson User-centered design, also known as UCD although I will use that abbreviation for usage-centered design, is a highly structured, product development process where the focus is on understanding the needs and goals of the user of the product.
Interaction Design ID is a methodology described by Alan Cooper where the goal is to provide end users with functions that are both desirable and useful. In ID, interaction designers focus on what's desirable, engineers on what they're capable of building, and business stakeholders on what's viable I use the term user experience UX to encompass all of these concepts — although there is good reason to distinguish between the various ideas, that isn't relevant for my current discussion.

An important question to ask is why should agile practitioners consider UX important? UX places emphasis on the usage necessary for roles to meet their goals. UX helps meet the goal of identifying the behavior the software should have. UX practices can be applied with varying degrees of formality, thereby making them compatible with agile methodologies.
Other important terminology which I use in this article includes: The product, which often includes software, under development. An IT professional involved with the creation of the system.A very old concept: the broadly educated person.
Simply, it refers to the integration of critical thinking, research, technical, and cultural/historical knowledge that has long. College essays are important because they let you reveal your personality. Learn how brainstorming and planning can help you write your best college essays.
