Rational Unified Process

There are primarily four phases or stages of development that is concluded with a release in RUP. Here is a quick review of all the four stages or cycles.

Inception Phase
In the inception phase, the goal is to develop the parent idea into a product vision by defining its scope and the business case. The business case includes business context, factors influencing success, risk assessment and financial forecast. This is to get an understanding of the business drivers and to justify the launch of the project. This phase is to identify the work flows required by the project.

Elaboration Phase
Here the architectural foundation, project plan and high-risk factors of the project are determined, after analyzing the problem domain. For establishing these objectives, an in-and-out knowledge of the system is a must. In other words, the performance requirements, scope and functionality of the system, influence the deciding factor in the architectural concept of the project. Architectural and planning decisions are governed by the most critical use-cases. So, a perfect understanding of the use-cases and an articulated vision is what this phase of elaboration looks forward to achieve. This is an important phase. Since, after this phase the project is carried on to a level where any changes might cause disastrous outcome for the entire operation.

Construction Phase
As the name suggests, the phase involves construction of the software system or project. Here, development of the remaining components and application features is performed. Thereafter, they are integrated into the product which is moved from an architectural baseline to a completed system. In short, the source code and the application design is created for the software for its transition to the user community. The construction phase is the first external release of the software, wherein, adequate quality with optimization of resources is achieved rapidly.

Transition Phase
Transition phase marks the transition of the project from development to production. This stage is to ensure that the user requirements have been satisfied and met by the product. The initiative is done by testing the product before its release as a beta version. This beta version is enhanced by bug fixing, site preparation, manual completion, defect identification and improving performance and usability. Other objectives are also taken up. They include

  • Training users and maintainers for successful operation of the system
  • Purchasing hardware
  • Converting data from old to new systems
  • Arranging for activities for successful launch of the product
  • Holding sessions of learning lessons for improving future process and tool environment.

Rational Unified Process mentions six best practices, which have to be kept in mind when designing any software. These practices help prevent flaws in the project development and create more scope for efficient productivity. These six practices are as follows.

  1. An iterative (executing the same set of instructions a given number of times or until a specified result is obtained) approach towards the software development.
  2. Managing user requirements.
  3. Use and test individual components before being integrated into a larger system.

    4. Use ‘Unified Modeling Language’ tool to get a visual model of the components, users and their interaction relating to the project. Constant testing of the software quality is considered one of the best practices in any software development.

  4. For a successful iterative development, monitoring, tracking and controlling changes made to a system is essential for a team to work together as a single unit.

Information Technology

All our work related applications are now completely automated, thanks to the IT sector. IT professionals are people involved in essential management of sensitive data, exclusive computer networking and systems-engineering. The advancement of the IT sector has resulted in automated:
•Administration of entire systems.
•Production and manipulation of sensitive information.
•Cultural development and communication.
•Streamlining of business processes and timely upgradation.
Advantages of Information Technology:

The advantages of information technology are many. True globalization has come about only via this automated system. The creation of one interdependent system helps us to share information and end linguistic barriers across the continents. The collapse of geographic boundaries has made the world a ‘global village’. The technology has not only made communication cheaper, but also possible much quicker and 24×7. The wonders of text messages, email and auto-response, backed by computer security applications, have opened up scope for direct communication.

Computerized, internet business processes have made many businesses turn to the Internet for increased productivity, greater profitability, clutter free working conditions and global clientèle. It is mainly due to the IT industry that people from diverse cultures are able to personally communicate and exchange valuable ideas. This has greatly reduced prejudice and increased sensitivity. Businesses are able to operate 24×7, even from remote locations.

Information technology has rippled on in the form of a Communication Revolution. Specialists in this field like programmers, analyzers and developers are able to further the applications and improve business processes simultaneously. The management infrastructure thus generated defies all boundaries. Among the many advantages of the industry are technical support post-implementation, network and individual desktop management, dedicated business applications and strategic planning for enhanced profitability and effective project management.

IT provides a number of low-cost business options to tap higher productivity with dedicated small business CRM and a special category for the larger operations. Regular upgrades have enabled many businessmen to increase productivity and identify a market niche that would never have been possible without the connectivity. With every subsequent increase in the ROI or Return On Investment, businesses are able to remain buoyant even amidst the economic recession. Not only do people connect faster with the help of information technology, but they are also able to identify like-minded individuals and extend help, while strengthening ties.

This segment revolves around automated processes that require little or no human intervention at all. This in turn has minimized job stress levels at the work place and eliminated repetition of tasks, loss due to human error, risks involved due to negligence of timely upgrades and extensive paper-intensive business applications that result in the accumulation of unnecessary bulk. The sophistication of the modern work stations and general working conditions is possible only due to the development of Information Technology.

Improving Detection Through the Use of Computers

Computerized Systems Improve Detection
The FDA has approved the ThinPrep Processor Model 2000 for automatically preparing slides making it easier for screening atypical cells. The ThinPrep system is especially effective for detecting low-grade squamous intraepithelial lesions (SILs) and some of the more severe lesions. The ThinPrep system concentrates the cellular material and filters out a lot of blood and other materials. This provides for better detection of cancer cells by the cytotechnologist.

Other new systems available to health professionals are used for screening the slides for abnormal-looking cells. One system, PAPNET, uses neural net computer technology. Its technology was originally designed to detect flying missiles. The system essentially learns by example. It is fed a series of digitized images of Pap slides, and from these slides, the computer develops guidelines for identifying abnormal cells. Once cells are identified by the system as “abnormal”, an enlarged color image of the cells is generated for the cytotechnologist for review.

One other Pap test re-screening system is the AutoPap 300 QC. This computerized system uses image interproduction and pattern recognition techniques for classifying cells as abnormal. Once the cytotechnologist performs a routine screening of the slides, the AutoPap 300 QC is used to re-screen the slides. The AutoPap 300 QC then scans the cells for hundreds of features, such as size, shape, density, and texture. Using sophisticated statistical screenings, it selects 10 to 20 percent of slides with the highest probability of having abnormal cells. These slides are then re-screened manually by the cytotechnologist.

Although these methods of detection are very effective in detecting abnormal cells, they are not foolproof. Also, there are a small percentage of women who develop a rare form of aggressive cervical cancer that can develop to advanced stages in under a year.

If you have been diagnosed with human papillomaviruses (HPVs), you could be at a greater risk for developing cervical cancer. Smoking also elevates the risks.

What can you do? Talk to your doctor about the testing methods used for your Pap test. Get regular gynecological checkups, as frequent as once per year. Do not douche or use vaginal spermicides or medicines within two days of your Pap test. Use barrier methods of contraception, such as a diaphragm with spermicide and condoms, and quit smoking!

Currently, the most effective way of preventing cervical cancer is early detection.
