...DELIVERY OF COMPUTING PROJECTS INTRODUCTION: A project can be defined as a process of creating a new product or service. It has a beginning and an end as stated by (Project Management Institute 2008). The outcome of a project is said to be tangible or intangible, even though it may present some project deliverable and activities, this will not change the unique characteristic of a project. However, the most essential part of a project are the relations stuck between the planning variables and their influences on project success. Most time managers advocate that project is successful if it meet the important target, namely, appropriate specification, cost, time and quality. This has significant benefits to organizations. However, Proper analysis will be done on how Waterfall and Agile Project Management carried out various projects successfully, and how the most recent computing projects turned out. WATERFALL PROJECT MANAGEMENT APPROACH This is a traditional approach, the waterfall model is a systems development life cycle model for software engineering (Project Management Institute 2008). Often considered the classic approach to the systems development life cycle, the waterfall model describes a development method that is linear and sequential. Waterfall development has distinct goals for each phase of development. The Waterfall approach suggests that the assessment of risks should be carried out at the beginning of the project. To carry out risk management in waterfall, it...

...1) Describe Highsmith's Agile Triangle. How does it differ from the traditional approach to handling project constraints? Do you favor one approach over the other? Explain. In the Traditional Iron Triangle, the constraints are time, money and scope. Time and cost in a project can be difficult to plan in advance. While in Highsmith’s Agile Triangle we focus on value and quality. The general idea behind the agile triangle is that we need to take the focus off of delivering to a set schedule, a fixed budget, and some predetermined set of deliverables and instead focus more on the value the product is delivering (Leading Agile). Traditional development teams are supposed to work within the confines of the ‘Iron triangle'. The three sides of the triangle are Scope, Schedule and Cost. Since Agile places a lot of emphasis on quality, it is often considered a dimension which sits at the middle of the triangle. I would prefer the agile triangle method over the traditional method as Jim Suggested constraints are important project parameters but they are not the goal of the project. Value and Quality are the goals and constraints may need to be adjusted as the project moves forward to increase customer value. According to Jim, Agile teams should focus on the releasable product rather than getting constrained by the iron triangle. The three vertices of the iron triangle collapse into one vertex of the agile triangle called constraints. The other vertices i.e. value and quality define...

Retrieved from IBM DeveloperWorks Website (http://www.ibm.com/developerworks/rational/library/4243.html). Agile approach to project management has become more and more popular in recent years. Agile framework is different from traditional waterfall model. It has considerable impact on how projects are planned and executed. Imagine that you have been assigned as a project manager to manage your company’s e-Commerce Website where customers can browse the company’s products, place orders, and interact with the company’s customer service representatives. Your project must be completed in three (3) months and you have about twelve (12) people in the team. There are three (3) offshore developers in Ireland and two QA testers in Dallas, TX. The rest of the project team and the product owner are in San Diego, CA.

...Study on Agile software development methodologies A B M Moniruzzaman abm.mzkhan@gmail.com Dr Syed Akhter Hossain aktarhossain@daffodilvarsity.edu.bd Abstract Today‘s business environment is very much dynamic, and organisations are constantly changing their software requirements to adjust with new environment. They also demand for fast delivery of software products as well as for accepting changing requirements. In this aspect, traditional plan-driven developments fail to meet up these requirements. Though traditional software development methodologies, such as life cycle-based structured and object oriented approaches, continue to dominate the systems development few decades and much research has done in traditional methodologies, Agile software development brings its own set of novel challenges that must be addressed to satisfy the customer through early and continuous delivery of the valuable software. It‘s a set of software development methods based on iterative and incremental development process, where requirements and development evolve through collaboration between self-organizing, cross-functional teams that allows rapid delivery of high quality software to meet customer needs and also accommodate changes in the requirements. In this paper, we significantly indentify and describe the major factors, that Agile development approach improves software development process to meet the rapid changing business environments. We also provide a brief comparison of agile development...

...Agile vs. Scrum Methodology Everyone involve in software engineering is driven by cost, schedule, and time by market. Customer wants software of yesterday and at the same time they want at high quality but at the cheaper price. The demand for faster delivery has been become more demand especially during the internet era and little likely hood and little more relax attitude toward budget and time to market will occur anytime soon at the same time change affect for software engineering requirement emerged development work is conducted as consequence that software team must react to new functions and features that impose by stakeholders and within the team itself. Modern software engineering is driven by the need to be agile. Works need to execute in the agile manner, communication must be conduct in the agile fashion, and change must be conduct in an easy way. Agile is a technique that delivery technologies or IT solutions. It focuses on changing business needs and technologies. In February 2001, a group of software developers got together to create what so called “Agile Manifesto” that declared and agreed among other things. * Highest priority is to satisfy customers through early and continue provides them with valuable software. * Changing in requirement during software development is welcome. * Business people and developers must work together daily in order to complete a project. * Face to face conversation is the most efficient and effective...

...Operation Suppy Chain & Management David Imboden, Livia Artuso, Clariss Chow, Youssef Hautier, Topic: Are Agile development / Scrum approaches applicable to other product domain than the software development? 1. Introduction The development of a new product is key for a company. The products can be very simple (a new fork in the Ikea assortment) to extremely complex (let’s think about a new airplane for Airbus), their development still requires a multidisciplinary approach, implies a lot of risks, a lot of uncertainties and usually involves a large amount of resources and cash. But what is exactly product development? We define it as the set of processes that will bring a concept or an idea to product that is used by the final customer, in volume. Other definitions can be found in the literature. We should note that Product Development can be applied to very different domain. Physical (or hardware) products (like the two examples stated above) are the first to come to mind. This category also encompasses products like a new molecule in the biotech industry or a new aliment for the pet-food industry. Millions of new products are launched every year. The time to market, the quality, the fit with the customer need, the integration with the other parts of the company (Customer Service, Manufacturing) are all critical to the success of this new product. It is no surprise that both the academic and industry world committed to develop better processes to handle Product Development...

...PROJECT LIFE CYCLES Student ABC Bellevue University Abstract – about 50 words not 30 … not 70 The purpose of this paper is to provide a discussion on the variations of a project life cycle. Specifically, we’ll compare and contrast two project life cycle variations, specifically the waterfall and legacy maintenance models. We’ll begin with a brief discussion of project life cycle models. Then we’ll examine the waterfall and legacy maintenance models. Then we’ll look at the differences between the two models. Lastly we’ll provide examples of how each model would be used effectively in a project. Project Life Cycles Project lifecycle models are not interchangeable. To deliver a quality system, it's critical to know the risks facing your project and to use a model that reduces those risks (Project Lifecycle Models, n.d.). For most business solution development projects with a significant IT component, and even for many non-technical projects, there are several project life cycle models that will likely meet your project needs (Hossenlopp & Hass, 2008). Waterfall Model The waterfall model is the classic solution development project life cycle and is normally used for small projects (Hossenlopp & Hass). It is one of the earliest models and is a sequential process in which progress flows through several phases from top to bottom, comparable to a waterfall (Indika, 2011). Its project lifecycle is typically: business requirements; system requirements;...

...Primavera Gets Agile School CIS/525 Instructor November 22, 2014 Primavera Gets Agile There is always a best practice and critical success factors an organization can adopt to turn the organization’s entire development organization around in the most amazing way. Prior to adopting agile project management, Primavera development organization experienced problems. Agile techniques should be considered when solving such problems while implementing strategies in adopting agile methodologies. There will be challenges and obstacles that Primavera will face when transitioning to agile project management, but with hard work, these obstacles can be tackled. From since 2004, Agile has continued to have an impact on Primavera project management and its economic growth. Problems prior to Agile Some may look at a company like Primavera and think that they had all the necessary software to operate flawlessly, but that was never the case. While scuffling like everyone else, Primavera once maintained the tradition waterfall development approach with a team working tirelessly to dispense high-quality services to a growing and diverse market, as swiftly as possible. In an attempt to complete projects on time, team members had to follow a typical cycle that demanded late hours and weekends. Project managers basically used what was called a command-and-control philosophy. In other words, only managers made decisions without consulting or getting input from their team. This cause the relationship...

...Agile Project Management Practices Art Valena CMGT 410 February 04, 2016 Mike Taousakis Agile vs. Waterfall Method in Software Development The Waterfall Method is used for a variety of projects. In this method everything is planned out ahead of time. In general this method consists of stages that have to be completed before a project. This method is great because potential issues can be prevented from occurring because these issues would be researched from the start. Another pro of the waterfall methodology is that everything is well documented from requirements to the design. Because the waterfall method is so linear, it is very simple to understand and teams are more comfortable with this approach. Although planning ahead of time may seem ideal and most practical, unexpected problems are bound to occur. Some problems can be researched before a project but that doesn’t mean unforeseeable ones will not occur. The biggest con for the waterfall method is that it does not have its on momentum. It is based on a set guideline. Everything is in a constant motion, technology is always changing, business and markets fluctuate, and the chances of delays due unexpected issues are more likely to occur using the waterfall method. Instead of extensive planning and design up front, the Agile Method allows the changing of requirements over time by incorporating planners, designers, developers and testers which work on successive iterations of the project over fixed time. The work...

...Ivey Case 910E24– Binnj on the Apple iPad Binnj’s chief executive officer (CEO), Clay Hutcherson, has assembled a team of people for a 100-day “science experiment” to determine whether a new high-tech business venture is worth pursuing. He is focusing on an untapped market—a new kind of restaurant menu service built on the Apple iPad platform. Members of the team are excited and have been furiously working o the project while retaining their full-time jobs. They have developed a prototype of the technology and business offering, pitched the idea to several clients and generated significant interest. The case, as you will notice as you read, is set at the end of 100 days, when Hutcherson must decide on the next steps. Address separately each of the following directional questions in sufficient detail with associated analysis/rationale.

...There is no IT meeting that does not talk and debate endlessly about Waterfall vs. Agile development methodologies. Feelings run strong on the subject with many considering Agile ‘so of the moment’, just so right, while Waterfall is thought to be passé! But, before deciding which is more appropriate, it is essentially important to provide a little background on both. Waterfall A classically linear and sequential approach to software design and systems development, each waterfall stage is assigned to a separate team to ensure greater project and deadline control, important for on-time project delivery. A linear approach means a stage by stage approach for product building, e.g. 1. The project team first analyses, then determining and prioritising business requirements / needs. 2. Next, in the design phase business requirements are translated into IT solutions, and a decision taken about which underlying technology i.e. COBOL, Java or Visual Basic, etc. etc. is to be used. 3. Once processes are defined and online layouts built, code implementation takes place. 4. The next stage of data conversion evolves into a fully tested solution for implementation and testing for evaluation by the end-user. 5. The last and final stage involves evaluation and maintenance, with the latter ensuring everything runs smoothly. However, in case a glitch should result, changing the software is not only a practical impossibility, but means one has to go right back to the beginning...

...Abstract: Agile methods in recent years have emerged as a new paradigm in software development, which promises to address some of the problem areas of traditional approaches by freeing some of its constraints. In an attempt to produce an improvised process to designing and implementation and thereby to produce qualitative deliverables, several pioneering efforts have been suggested. This paper examines two such methodologies that promote agility: eXtreme Programming and SCRUM. The process, the values and principles of the XP and SCRUM are described in detail. Crucial feature differences between XP and SCRUM and the advantages and disadvantages of both methodologies are also discussed. Keywords— XP, SCRUM, Agile INTRODUCTION The software development industry has been evolved to become the most important industries of time. This industry employs many practitioners world wide to create the most essential products that is been used to extend our lifestyles. From controlling the production of food we eat to providing safety and control of the vehicles, software has become the embodiment of the world's most valuable intellectual property.[15] In last few years, the trend to more agile has been the most significant event we have seen since the application of traditional software development process. The agile software methods and development is practices based approach which is empowered with values, principles and practices which make the I. software development process more easy...
