Waterfall Method: In 1970, Winston Royce proposed the famous "waterfall model," which was the only widely adopted software development model until the early 1980s. The core idea of the waterfall model is to simplify the problem according to the procedure and to separate the realization of the function to facilitate the division of labor and cooperation. The project life cycle is divided into six basic activities: planning, requirements analysis, software design, programming, software testing and implementation, and provides a top-down, as waterfall, step by step fixed order. Advantages: 1. The project provided a checkpoint by stages. 2. After the current stage is completed, you only need to focus on the following stages. 3. Stages are …show more content…
It’s hard to use agile method when deal with big project with larger teams. 2. Project using agile method is hard to estimate which bring risks to the company. 3. Agile method require high-quality talent and the vague division is also requiring participants are knowledgeable and professional Applications: 1. Project needs frequent modification and improvement. 2. Agile method is suitable for small project developed within department which require few people to participate and quick implementation. 3. Project needs a short life cycle and a bigger freedom. 4. Agile method is most useful while the project is user-focused and needs early customer participation. I think both methods are useful depends on the nature of the project and the developers involved. The waterfall method is clearly suitable for big project which require huge labor, cost and time. The agile method will be very helpful for departments which want to implement small …show more content…
For example, the marketing team is sometimes asked to deliver a quick summary or research of customers. It requires very few people to participate but needs a quick feedback. Agile method will be a good choice to guide a small project like this. Agile method can help team deliver quick and high-quality development, testing and cooperation. It requires frequent communication between developers and managers which help both sides to build up experiences and trust. A simple workflow for agile method is as following: First, define the team 's role. In agile development, there are three types of roles: stakeholder(who care about products and deliver usable products), product owner(who need to plan the product and collect feedback) and development team. Then identify a project backlog (a list of project requirements in order of priority) and pick out one as the goal of one iteration. Then product owner will divide it as smaller task to each member and hold daily meeting in which everyone report their status. After each iteration, the project team should do a presentation to customers and executives and a review meeting after that. Then repeat. Agile method is easy to understand but hard to implement. The most important thing of implementing a agile method is that every participants should believe in the method which may require self-learning and high-level leadership of the managers. Agile method can certainly bring
What do you think when you hear the name Cummins? Most people think power, torque and reliability. Cummins is a very common name in the diesel world. Dodge and Cummins began their partnership 25 solid years ago, longer than some marriages in this century. Let me take you on an adventure of the history of Cummins, B-series Cummins, as well as the 12 Valve, as well as the 24 Valve engines.
At the turn of the 18th century, America had faced a troubling election that would give them a very different experience than the previous elections. In the novel A Magnificent Catastrophe, Edward J Larson depicts the thrilling story of the election of 1800, an election that has, in essence, establish the political system that has since shaped the way modern politics is handled. Larson goes into depth on the political race that would establish the creation of a two-party system and inform the reader on the election that held the first real presidential campaign. In an intriguing tale of the clash between two completely different ideologies, Larson informs us on the drama and convulsions of the election of 1800. Demonstrating exactly how Vice
Your work on Julius Oppenheimer was very developmental in the way you constructed your CAD, which created a great story that framed his personal and professional issues that had major influences on his being and legacy as a member of history that will never be forgotten. However, I had to read your post three times, looking for the theme of the CAD and quickly understood you could not have selected a figure that would have been more difficult in describing part one of the exercise. Your description of his life, ailments and vulnerabilities were precise and painted a clear portrait of the items that contributed to his experience and likely enablers that were critically important to his knowledge, skills and abilities that ultimately led to
These stages are integral to the research process and require careful consideration and planning.
Eisenhower was the first president to use the term "Domino Theory". By early 1954, many U.S. policymakers that the french were failing in their attempt to re-establish colonial control in Indochina, which they lost during WW2 when the Japanese took control of the area. The Vietnamese nationalist, led by the communist Ho Chi Minh, were on the verge of winning a stunning victory against French forces at the battle of Dien Bien Phu. In just a few weeks, representative from the world’s powers were scheduled to meet in Geneva to discuss a political settlement of the Vietnamese conflict. U.S. officials were concerned that a victory by Ho’s forces and an agreement in Geneva might leave a communist regime in control of all or part of Vietnam.
The seventh step involves implementing the change into a test program. To assess the program's performance, the pilot program should first be implemented in one or two smaller locations or units. The eighth and last phase is to assess the pilot program's outcomes. The team should determine whether the program is viable and whether it leads to quality results like
Phase II(sub-acute phase): When you leave the healing facility, your heart recovery project will proceed at an outpatient office. Stage two of cardiovascular restoration more often than not endures from 3-6 weeks and includes kept checking of your heart reactions to practice and movement. Another imperative part of stage two cardiovascular restoration is training about fitting activity methodology, and about how to self-screen heart rate and effort levels amid activity.
In his essay The Model of Rules I, Professor Ronald Dworkin argues against a certain theory of law he attributes to H.L.A Hart called “positivism.” While Dworkin argues against many tenets of the positivist theory, I will focus this essay on critical reasons against Dworkin’s argument against the legal positivist thesis that the law consist of nothing but rules. To do so, I will explain the necessary components of Hart’s theory of law required to understand Dworkin’s rebuttal. Then, I will reconstruct Dworkin’s argument against what I will classify “nothing but rules” claim, and I will ultimate claim Dworkin’s argument fails because his premise that states principles are extra-legal and cannot be explained as part of the categories is false. In particular, I indicate how principles can be legally binding like legal rules are, and I pick apart his reasons for believing that there are clear distinctions between laws and principles.
the project, this will be include creating the interfaces, building the application logic, creating the database and integrating all the three tiers to meet the functional requirements laid out in the project specification. Testing phase – 1 week This stage involves unit and integration testing of all the modules implemented in the previous stage following the test plans laid out in design phase. Test results are to be created to demonstrate the effectiveness. Testing will focus on security, performance, usability and accessibility of the
Iterative and incremental approach is a better way of developing requirements and modules as well. 4. Requirements provide a complete operating picture of the solution, which helps in taking correct decisions during initial stages of software development life cycle (SDLC). Iterative and Incremental Approach This approach allows us to make changes before it is too late.
Explain your recommendation. Since most of the functionality is known for this application and there are few moving parts, I would recommend using the traditional waterfall approach. I base this decision on the following factors: 1. The system is of low to medium complexity and most of the functionality can be achieved through well- documented and widely-used technologies. Hence, the design of the application could factor in most of these technologies and the development team could come up with a more detailed and finalized approach for the system.
Tom Godwin’s short story “The Cold Equations” illustrates how one should think of and become accepting of their consequences whether it's deserved or not. The story is about an Emergency Dispatch Ship, also known as an EDS, with the pilot on a mission to give a group of six men who have a fatal fever. The pilot, Barton, during his mission finds a stowaway named Marilyn found in a small closet on the ship. Marilyn was a young girl trying to go to Mimir, for she had a destination waiting and hoped to see her brother who she hasn't seen in 10 years, but little did she know that there was a previously set protocol that determines the life of a stowaway. Barton had sympathy for the girl and did his best to help her by contacting headquarters and asked if there was any way he could spare Marilyn’s life
This approach centers on people, communications, the anticipated product and its flexibility. The concept of this approach is similar to that of the traditional management approach: generating plans and requirements, evolving the anticipated product, incorporating it with other products as required then testing it and debugging technical hitches if any is found, then lastly fitting it for use (Rose, 2010). In this approach, as a replacement for focusing on the phases all at once like it is done in the traditional approach, the entire project is fragmented into smaller segments known as scrums after which the scrums are taken as smaller projects and dealt with according to the traditional
It is important to emphasize that these challenges were brought about by poorly defined goals and the scope was usually unclear. This meant the projects usually tended to go beyond the estimates as the project developers tried to fix newly developed ideas in to the development process. the phase gate model was developed to give an outline of the project development process to offer solutions for managing newly launched
