    Pt2520 Unit 3 Metrics

    In this presentation, the author has explained different metrics and there attributed used to measure software. A person can only measure and represent it in number when he knows something about it. On the other hand, if has no idea about it then he doesn’t have any idea about it [1]. There are two types of software complexity metrics. One gives the efficiency of the machine while running the software which is called as computational complexity. Another one is giving us the factors which affect the software developer capacity to develop good software which is known as psychological complexity. There are two types of software metrics. The process metrics which gives details of the process used such as software life cycle used for development, the time consumed for the development etc. The…

    Mr Ramos ITSC 1405 CHAP 1

    3. The impact of the evolution of computer hardware and the accompanying evolution of operating system software is as follow: As experience with a combination of hardware and software matures; users and engineers gain new visions of what they would like to do next. New hardware is usually paralleled by operating system and system software development. The fielding of new systems results in user and operator feedback that leads to operating system and system software improvement. Innovative users try equipment and software for applications not envisioned by the hardware and software vendors. Successes lead to additional sales and use, which leads to further supporting software development. If there is perceived economic benefit, the hardware vendor will seek ways to adapt to the new needs without necessarily sacrificing basic capabilities. Often this consists of creating a more efficient interface.…

    Application Developer vs Software Developer

    Software developers make effective software. It is an engineering endeavor that cannot be extracted from the context and systems with which it interoperates. The heart of a good software solution is not in turning the functional specification into code but rather in the use of available resources such as time and money to create desired outcomes for stakeholders, while satisfying constraints such as legal requirements through purposeful design.…

    Supply And Demand Simulation Analysis

    In the video, several principles and concepts of microeconomics and macroeconomics were simulated. In the simulated neighborhood of Atlantis, there are many amenities that customers demand. The simulation uses two bedroom apartments to teach the fundamentals of supply and demand. Several scenarios were used throughout the simulation to represent challenges with which management needed to contend. The scenarios showed how price can affect supply and demand while still being competitive within the market. Within the simulation, microeconomics are used. Microeconomics contends with smaller business sectors, while macroeconomics focuses on the entire economy (DifferenceBetween.net, n.d.). The simulation shows an example of microeconomics in the first scenario. Rental management within this scenario must calculate a rental rate for their two bedroom apartments that will decrease vacant units and increase revenue (University of Phoenix, 2012). This scenario relates to microeconomics because it aims toward supply and demand. The management team needed to decrease rental prices to decrease rental vacancy. Macroeconomics is represented in scenario two, which shows that the rental company has 2500 vacant…

    Software Engineering

    I have many goals in mind for my life. I want to graduate university, possibly go to graduate school, and obtain a career in which I am happy and satisfied. Yes, I know this sounds very cliché as many people want to obtain this kind of life. I don’t mind obtaining a “normal” happy life as long as I am happy with it. I am familiar with Maslow’s Hierarchy of Needs and I want to make sure I fulfill my lower needs before I start trying to achieve my goals. I have never actually applied the GIOADA process to my decision making in the past. After reading the document that describes the GIOADA process, I will start applying this process to future decisions I make in life. Also, as I look back at some of the big decisions I made previously, I wish I applied the GIOADA process in making these decisions. That would have allowed me to more strongly analyze all the processes of the decision making.…
