We should remember that software development methodologies are all milestones in the continuing evolution of software engineering. This evolution is still continuing and there will be more variants in the future. And, depending upon the nature of the software development project, the choice needs to be different. A compatible Process Methodology accelerates the delivery of high quality custom software. An Agile Process Methodology follows a controlled, iterative development and prototyping process.
For prototyping, they utilize the latest tools and technologies that are best fit for the software and client approved. The prototype design is sent for client approval, after which development process commences.
1. Prototyping is a means of exploring ideas before you invest in them. The best reason to prototype is to save time and resources. So, for a minimal investment, you can find usability and design problems and adjust your UI before you invest heavily in the final design and technologies.
2. On examining the needs of your particular project, you might come up with reasons for creating a prototype other than saving money. Is the goal to explore a new interface model? Make modifications to one part of the existing design? Investigate a new technology? It’s important to be clear about why you’re building what you’re building before you start. If you begin with clear goals, you can be direct and effective in your efforts. The reasons for creating prototypes fall into three basic categories:
Proof of concept.
1. Among some teams there are disagreements about the future direction of a project. You can use a prototype to prove that an idea or new approach has merit or value. A prototype can help illustrate that an idea works, express its qualities in a visual and interactive way, and/or motivate team members to think about the problem from another perspective.
1. If you design interactive things, the only way to explore how something will be used is to create a mock-up and interact with it. Sometimes the mock-up is tied to a usability study, where parts of the prototype can be evaluated in a structured way. Sometimes it’s just a way to clearly express to a developer how something should work or look. In many cases, a designer might simply be experimenting, in an effort to get a sense for what approach might work. Anyone on the team can use prototypes to explore design issues, although designers are generally the most skilled. Design explorations should be directed at trying to solve specific problems that you’ve recognized in your product.
1. Developers investigating implementation approaches to a problem often try out different coding techniques to see if they work well. Using HTML, Jscript, SQL, DHTML, Win32, or specific coding approaches within each technology have different tradeoffs. Sometimes a prototype represents an exploration into what technology will work well to support a certain UI or web feature.
2. Sometimes prototypes are created for a combination of these reasons. If a team plans well enough, they can allot time for a developer and a designer or project manager to work together on a prototype. In such cases, it’s extremely important to clearly define the goals and the contributions each team member is expected to make. You want everyone to be clear on what the goals are, what’s at stake, and what the potential outcome will be.
Who is Involved?
1. Prototyping can be done informally by anyone, regardless of their background or role in the project. It’s easy to make a simple but effective prototype by taking a bitmap from Adobe Photoshop, putting it into the Microsoft FrontPage Web site creation and management tool, and adding active buttons or links. These lightweight prototypes only go so far, and can become unwieldy for complex interactions.
2. For more formal prototypes by larger teams, a developer or project manager will often collaborate with a designer and a usability engineer. Together they’ll generate ideas, build a prototype that represents the best ideas, and then go into the lab to see how effective it is in solving user problems. Developers might get involved if they can spare the time, or if their technical expertise is needed. Often the designer or project manager will do most of the scripting or coding to build the prototype.
The same applies to software development. The architecture stage is a time when the software is mapped out through the use of design diagrams and prototypes. As in building construction the architecture stage provides a means of exploring alternatives at a relatively low cost.
Any project risks will be addressed and the project altered to reduce the risks by the end of this stage. If any of the stages were skipped or not taken serious by the team the project is destined to fail. Sadly a large number of projects fall victim to this, due to the fear of budget and schedule overruns. The reality.... it costs 50 to 200 times more to make changes to the software after this stage.
The abstract representation of a software system is known as Software Architecture. We ensure that the software system not only meets the current requirement of the product but also supports the future requirements. We, as part of Software development architecture ensure that the software system interfaces with other software products, hardware, operating system etc.
We managed to do this with the help of our ever expanding team of potential experts, working with cutting Edge Technology Architecture, Business Architecture, Process Architecture, and Workforce & Workflow Architecture in specific domains.
