Waterfall model

M4D1 I. Why do you think it is much more expensive to fix a security vulnerability late in the software life cycle, compared to early? It is almost always more costly to redo or rework something than to do it correctly in the first place. Years ago when I got my first Solaris system administration job, the Navy had the view that any job the Navy did not have official schools for could be learned via OJT (on the job training). So for my first year, I learned everything I could about…

In this section I will justify my choice of choosing agile over waterfall and talk about other common techniques found in agile environment, that I have applied. I decided to include this chapter because I believe the way you approach development strongly links to the final outcome. The nature of my project involves making many changes as I am producing the application. Therefore, I decided to choose agile development for this application. This means I am not doing any heavy documentation and…

Smith and I had a productive software security concerns conversation with Vipul this past Thursday (6/1/17). One of the questions we asked him was if Ebix has some sort of ISO certification like ISO 9126 and found that they do not. Per Vipul, Ebix is CMMI level 5 compliant and explained that this accreditation has more rigorous requirements than ISO certification. Vipul will share a framework document that lists ten security/risk assessment tenets that Ebix follows to build secure web…

Businesses to achieve their goal for which they are set up involve number of activities. To better handle or manage these activities or to make the work easier these activities are divided into smaller activities or tasks. A process is simply a well-defined set of steps and decisions points for executing a specific task (Vsellis, 2015). Streamlining these tasks, certain agreed upon steps are followed. So process methodology is an agreed upon way of doing business or running these activities. A…

I have worked closely with a waterfall environment and currently am an active member of an agile environment at my current employer. For the most part, I know the ins and outs of the agile environment from acting in the role of Product Owner. As the Product Owner I work directly with the Scrum Master and developers to prioritize the work that needs to be done to achieve desired results for the business. Not only do I prioritize the work to be done, I also have to make critical decisions on…

complete project is sequentially moderated and assigned alternately to each of the teams. Collaboration between the teams, in this case, is minimal, restricted to communicating through the various interface provided. Unlike the traditional development model, the 24-h knowledge factory partitions tasks vertically, meaning that each of the project’s modules may be worked on by all teams, in a cyclic and orderly manner. In short, the continuous development increases the overall efficiency of the…

SOFTWARE ENGINEERING JAMESTER C GO BS COE 5A 3.1. Reread “The Manifesto for Agile Software Development” at the beginning of this chapter. Can you think of a situation in which one or more of the four “values” could get a software team into trouble? Manifesto for agile software development: 1. Individual and interactions over Process and Tools. - It is the first value proposition of the manifesto. This tool should be used for capturing requirements, version control, project planning, editing,…

Aqua America’s Software Methodology Justina Khuu The majority of Aqua America’s software is developed using the waterfall method, whether it is in-house or through contractors. Oftentimes there is a meeting set for requirements gathering between the developers and the managers or directors of the department that is to benefit from the software development, and then minimal contact between the two groups until the product is delivered. While this results in the least amount of upfront cost by…

Gattaca, is it really down to a science? “Technology makes things faster and more cost-effective, but it's not perfect. It requires you to be as flexible as you can be. - John Phillips” This relates to the society in the movie “Gattaca” due to the fact that the society is only for the “people” that are “valid” meaning that only people that have been genetically modified are accepted in the advanced work field of the future. Due to these facts that only “valid” people are accepted in the world,…

analogies of small teams working for a single objective. Scrum is one of the most popular agile development methodologies and one of the easiest transitions from the waterfall approach, since it’s typically requirements-driven like waterfall but involves shorter iterations with shorter degree of collaboration. Similar to waterfall, scrum is driven by a requirement or user story that defines how features should perform and be tested — but with one significant difference: scrum…
