A Project Management Overview of XP Software Development Methodology This paper will discuss at a high-level how software development projects are run when implementing the extreme programming (XP) methodology, and explain during which step, XP covers the Project Management Institute’s (PMI) process groups, and management knowledge areas (MKA) [9]. After the XP process is discussed, XP’s unique way of developing code, its documentation management, and user-centric approach are explained. Since XP is written as being easy to implement, a short discussion of where the real work occurs is included, then guidance on what types projects it is best to implement XP. A brief overview of agile methodologies (AM), of which XP is but one, is included first. Agile Methodologies The characteristics of AM are that they the value “(a) individuals and interaction over processes and tools, (b) working software over comprehensive documentation, (c) customer collaboration over contract negotiation, and (d) responding to change over following a plan”[1]. AM concentrate on developing functionality over managing the development of functionality. The management of traditional software projects favors a well-planned approach – typically called the “waterfall approach” – documenting all project details before development starts. AM advocates creating a high level design of the whole system, then working on functionality in ascending order from highest to lowest in customer perceived business value. All AM assume requirements will change constantly so shorter development cycles are instituted to accommodate for the new or changed requirements. AM also assume close contact with the business (for the purposes of this paper, business, client, & user are used interchangeably) to answer any questions, and help resolve issues related to design, cost, and scheduling. XP Step One – The Planning Game The first step of an XP project encapsulates the PMI Initiating and Planning processes and is called the planning game. The planning game is a meeting in which desired functionality is discussed and analyzed via the creation of user stories [1]. Participants are users, project and development managers, architects, and developers. Other stakeholders, from the business or development side who can add value to the design of the functionality of the proposed system, are included when needed [3]. After business prioritizes the user stories, development estimates how many top priority user stories can be achieved within the first iteration/coding cycle (iteration velocity [5]). This process continues until all user stories are planned for in subsequent iterations, thus creating the project plan.
The purpose of this document is to compare and contrast three different Linux vendors in regards to their specific server and workstation OS products they offer in the workplace. In addition, I will discuss the price for each vendor, specifications, performance, and reliability. The three vendors I would like to discuss are Arch Linux, Red Hat Enterprise, and Ubuntu. Linux is an operating system that has several distros to choose from. Linux allows the user more control of the system and greater flexibility. As an open operating system, Linux is developed collaboratively, meaning no one company is solely responsible for its development or ongoing support. Companies participating in the Linux economy share research and development costs with
Agile project management is an iterative approach to the planning and monitoring of project processes. Agile projects are conducted in smaller tranches called iterations with each of these iterations closely reviewed and critiqued by the project team (employees, representatives of the clients etc.). The knowledge gained from this process is then used to ascertain the next steps of the
Extreme Programming (XP) has spent the past decades under perpetual scrutiny by software developers fixated on up front design methodologies. The idea behind this is simple: if you want to make sure something is well built, you must design it well first, then put it together using reliable tools. For objects such as houses, cars, or tables, of which the design evolves gradually throughout decades, the methods of up front design suffice. Computer programs, on the other hand, are products often made for an industry that evolves at higher rates than any other. For this type of environment, more dynamic methods are required, which is why XP suits as a viable candidate.
In every project there are always some universal characteristics that will be shared. They all have a comprehensible and established purpose and very distinct life durations. Overall, all projects are doing something that may possibly be new or yet a one time endeavor but have explicit requirements which include; time, price, and performan...
The projects in today’s world are given a lot of importance and it will continue to grow in the coming years. There are a lot of companies which do not have production, but all of them do have projects. There are a lot of books which have been published on which related to planning and managing the projects. The one of the most important one was published by the author Eli Goldratt in his book ‘Critical chain’. This book basically talks and shows how the application of theory of constraints in the field of project management. The novel is basically based on one of the MBA classes in America where a number of ideas are developed in discussions among the students and the lecturers. The lecturer is basically fighting for a tenure with the president of the university who expects a downturn in the executive MBA. The lecturer who teaches project management has a word with one the senior colleagues and project management was the right topic to teach. There were three students who were placed in the project management team of their company which manufactures electronic products. The students are enrolled in this MBA class along with other students, here they discover a new approach to project management which is known as the
During this research only three methodologies wiz Rational Unified Process (RUP), Rapid Application Development (RAD) and Extreme Programming (XP) are considered. The paper is divided into 6 sections. Section 2 & section 3 describe about the basics software development methodologies (RUP, XP, RAD) and Fuzzy Logic respectively. In section 4, our proposed approach is discussed while section 5 concludes the
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).
Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.
Williams, (1997) identified four steps to system planning. Earl (1989) proposed five alternate strategy frameworks which project managers should consider when deciding how the system will enhance the business function. Standard business strategy methods are used to identify such opportunities by using: value chains, application searching and information analysis (Earl 1989).
The topic of my group (group 4) was “How to totally float through your project for free” and the presentation was held by Roger Goodman who works for PMI NZ and Ernst & Young supply chain management with many years of working experience in many different countries such as Saudi Arabia and China.
It is possible to have a singular methodology for project management to specify morality and ethics when dealing with customers. Application of agile project management approaches like Atern offer a more inclusive approach for stakeholders including consistent update and revision of strategies. When the project manager violates protocol, all stakeholders should come together, clarify issues of violation, and set standards for all to follow.
As more companies that are leading technology are transforming from the traditional waterfall development model to an Agile software methodology, requirements engineering provides a process for software engineers to understand the problems they need to solve (Martin, Newkirk, & Koss, 2014). It is of key importance to understand the customer 's wants and needs before beginning designing or building the computer-based solution, as developing a solution that ignores the customer’s needs provides value to none of the parties involved. Thus, the intent of requirements engineering is to produce a written understanding of the customer 's problem (Pressman, 2010). Work products that are available to communicate this understanding include user scenarios, function and feature lists, analysis models, and specifications. This paper provides an evaluation of requirement patterns, an assessment of problem solving techniques most effective, a descriptive explanation of the patterns that includes a visual taxonomy, and an explanation of how the patterns identified are related.
The Software development field has grown with exponential rate. New products are coming to market daily. New innovations are flooding. Today the world of Software development is very large and much more complex than at any time. New software in large amount is hitting the market from beta version to fully functional products. This near-exponential growth in Software development market isn’t limited to any one segment of market. Rather it’s to Software Development as a whole – and it represents a huge challenge that must be addressed.
Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.
The chapter ‘Project Management in the Automotive Industry’ by Christophe Midler and Christian Navarre from The Wiley Guide to Managing Projects (September 2004) traces the inception and transformation of project management in the automotive industry from the post-war period to the early years of the new millennium. It is an interesting article which categorizes the period into four phases on the basis of organizational structure and strategy pertinent to most of the automotive manufacturers in each era. This classification helps the authors elaborate on the change in corporate structures and relationships within the organization and with their subcontractors over the years. Examples of leading car manufacturers have shown how project management has developed into an essential aspect of managing complex activities, and how the automotive industry has steadily evolved from being function-oriented and bureaucratic to being innovation-oriented and modular.
