Lean Software Development

by Andrew N
As the world changes, so does our business, we become focused on building products but we love to ensure that they are the best. This leads to some troubles of how this can be done, how are you sure that your product is made completely, and it is the best product possible. But not only does this apply to physical products it also applies to software development. Because in order to be the best, there are many things that you need to take into account. Many people claim they have a great development method to ensure that your software will be the best it can be, most of these methods come from the simple SDLC model  as the father but some come from a whole other world. This topic is important to this class due to the fact that it shows the many different methods used in software development and system design. Lean will show how important it is that when trying to develop any project it is important to try and reduce waste and to consistently keep the project updated. read more...

Agile Scrum Methodology

by lm F
Introduction
Among various methodologies used in systems development, agile development is favored for its rapid and flexible response to change. Especially in an increasingly competitive world where changes can occur in a quick and frequent pace, agile development methodologies are becoming more desirable (Nishijima, 2013). One agile methodology that I would like to share is called Scrum. read more...

Virtual Combat Training comes closer to Reality

by Miguel M
The article that I chose to talk about in this blog is about the new virtual training aid called “VirTra”. VirTra stands for Virtual Training which is used through military and commercial training. Now I used this article for this blog because it reminds me of the emphasis of project initiation because when this system was built it identified the markets that the system wanted to be used in. According to PC magazine “VirTra Systems markets combat, marksmanship, and situational awareness/judgmental firearms training systems to military agencies such as the U.S. Air Force, and to national and international law enforcement agencies” (PR Newswire 2004). The beauty of this program is that it can use all five senses to create a near-realistic experience whether it is a shooting experience or a flying experience. The goal of this is being able to make a very costly and dangerous experience cheap and safe. Now the beauty of these systems is that they cover a range of plans from economical to a fully immersed and high-tech plan; they have an electronic style range where you shoot at a projection from afar with electronic weapons and there is also the full 300 degrees virtual realm.
Now, the amazing thing about this technology is that it is all done without any headsets. This capability is provided to them with their acquisition of the Immersa-Dome technology, which keep in mind that it only works with the 300 degree option. According to PR Newswire, “VirTra Systems’ Immersa-Dome is the world’s first-ever individual, multi-sensory, projection-based virtual reality system. The Immerse-Dome utilizes a domed-shaped screen, which comfortably surrounds the viewer and delivers a high-resolution virtual reality experience without a headset. Through the unique design, the Immersa-Dome offers an amazing view of a photorealistic environment with resolution and field-of-view nearly equaling human vision itself” (PR Newswire 2004). Now this kind of technology is a big leap to what we currently have because the way this system works is quite phenomenal because in a matter of a few years the technology has blown up into a real amazing level. According to Bob Ferris, VirTra System’s President says, “Furthermore, real-time tracking of the trainee allows more natural interaction within the environment. Essentially, this technology enables trainees to look around corners or over cover, and brings us one step closer to holographic or “holo-deck” type simulation conceptualized by the popular Star Trek television series.” (PR Newswire 2007)
The floor of the V-300 model functions as the center of the arena so as the character moves through the scenario and the beauty of this training aid is it can be used in multiple ways as you can use the inner screens and the outside screens so there can be five lines of fires being used at one time. Now with the smelling aspect of the training, in an emergency scenario with burning rubble, the scent can be replicated and produced in the building so it creates a real virtual reality to any trainee using the simulator. With the feeling sense the weapons being used during the simulator create a recoil feel to it and you also get magazines to use to reload. The visual aspect of this training aid is that with the Immersa-Dome I creates a realistic world as close to the real thing and with the editing aid it provides the instructor can create a variety of scenarios ranging from an Iraqi showdown to a standoff in an airport, the program allows you to choose a scenario that is already programmed or a random scenario that they want to create.
This is also one of the best tools to use for training because when it comes to combat training they always emphasize to train as you fight and what better way to create a virtual world that is the same as their real world. Also what this creates for the trainees is confidence in their abilities to react on any scenario they may encounter because it may be a possibility that they encounter it in the real world, it also creates a sense of enjoyment of their time spent in training because when people enjoy their training they remember their training more vividly and without hesitation. Now even though this may seem to people like a game it is that but it is more than just a game it is a good practice tool and one of the cheapest and safest way to train our police forces and combat arms forces. read more...

Amazon Drone: Revolutionary Delivery System

by J C
Humble Beginnings
Jeff Bezos, founder and CEO of Amazon, Inc. worked in investment banking before he would create the conglomerate company known worldwide in 1994 by starting out as an online bookstore. Bezos’ reasoning for creating an online store was the “2,300 percent annual growth in web usage” (Price III, 2013) that was experienced during this time. With Amazon, Inc. being a pure online store with a wide database, it allowed the company to house numerous amounts of books without the limitations of on location bookstores.
When Jeff Bezos hired new employees, he emphasized on customer service as being the number one trait and priority for his new recruits. He would also have humble desks for his workers to use which would be “made of doors and 2x4s” (Price III, 2013) not only because they were least costly but to show the work environment that Bezos hoped to create. Within the next few years, Amazon, Inc. would become millionaire company and within the later years in the billions.
The Amazon Drone
The idea of the drone is to deliver packages in thirty minutes for faster satisfaction from customers and to hopefully pave a way for a normal form of deliveries for other companies in the near future. A viral video of this drone, a.k.a. the Octocopter, has circulated over the web showing the process of how the delivery process would work. In the video, an Amazon warehouse worker puts a single item into a small, plastic yellow tub. The box then travels on a conveyor belt, which stops under a Prime Air Octocopter. The Octocopter grabs the package and takes off outside the warehouse doors. It continues to fly over fields, urban areas, and finally reaches its destination dropping the package off at the front of the door. Bezos says that these drones will only be able to carry up to 5 pounds which accounts for “86 percent of the items Amazon currently delivers” (Maisto, 2013). Amazon continues to work with the Federal Aviation Administration (FAA) on rules for unmanned aerial vehicles to be permitted in the urban skies (Maisto, 2013). By 2015, Amazon anticipates to begin implementing the Octocopters in their Prime deliveries with the hope that the FAA’s rules will be in action by that time.
Complications
An expert on unmanned aerial vehicles named Dr. Darren Ansell brought up a few challenges that Amazon will face with its drone debut. Ansell talks about the Octocopter’s awareness saying that “The UAVs do not currently have the awareness of their environment to be able to avoid flying into people… to deliver goods to people’s home for example in residential areas, the UAVs must overfly densely populated towns and cities, something that today’s regulations prevent” (Maisto, 2013). Ansell also talks about the security issues suggesting that since the drones are unguarded that they are vulnerable to theft as well as with the package.
Some people are also concerned that with the implementation of the drone, the postal service will only have the task of returning unwanted packages. Amazon, however, have had talks with the United States Postal Service to reserve Sunday as a shipping day for them (Rash, 2013). This idea is already in effect in the New York and Los Angeles area and in time will apply nationwide.
Conclusion
The Amazon drone will revolutionize the delivery system we know today by enacting a faster way to receive packages. As with every new process, there are some issues to overcome, as well as some barriers to deal with. However, Amazon, Inc. has already started on ways to work with government organizations to overcome some of these obstacles by working with already placed laws on air travel. The Amazon drone is something of a work of fiction that will be seen by all in the near future. read more...

Advancement of User Interface

by Matthew C

A business’s website can show a lot about the company, and is often the first impression of the company to its potential consumers. In our current world of cutthroat competition between businesses trying to market similar products, a first impression can mean the difference between acquiring a new customer and a failed customer.  One way companies have been trying to improve their first impression, it through the user interface of their website.  A website is worthless in the business world if it is not easily accessible to its target audience and even somewhat outside of it.  So how are businesses today one upping their competitors in terms of website functionality?  Well, they have a wide variety of options, ranging from functionality to aesthetics.  However, companies are trying to improve both of these aspects through the advancement of the user interface. read more...

Project Management in Virtual Teams
