...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...

...AGILE PROJECT MANAGEMENT "On February 11-13, 2001, at The Lodge at Snowbird ski resort in the Wasatch mountains of Utah, seventeen people met to talk, ski, relax, and try to find common ground... What emerged was the Agile Software Development Manifesto." (www.agilemanifesto.org) The precursor to Agile project management was the brainchild of Dr. Winston Royce. Introduced in his 1970 treatise, “Managing the Development of Large Software Systems,”1 Dr. Royce presented a 5-point rebuttal of the sequential development Waterfall Model, which had been the status quo for project managment. The waterfall model views a process as a series of steps cascading downwards as shown in the illustration below: Fig. 1: The Waterfall Model Originating in industries concerned with complex physical structures such as skyscrapers, vehicles, and machines, the waterfall model suited these type of projects. The underslying assumption was that late-stage modifications were constrained by the high costs and difficulties inherent in physically modifying a large, complex structure after construction or assembly had begun. The first sequential project management protocol is attributed to Walther Shewhart at Bell Labs, who coined the phrase "Plan-Do-Study-Act"2 in the 1930s. His ideas were advanced in the following decade by the so-called "father of the post-war Japanese industrial renaissance",3 William Edwards Demings, Bell and...

...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...

Given these facts, this paper aims to investigate, through practitioners' perceptions of value, which agile practices are being used to improve two performance criteria for software projects—cost and scope. Using a multivariate statistical technique known as Exploratory Factor Analysis (EFA), the results suggest that the use of agile practices can be represented in factors which describe different applications in software development process to improve cost and scope. Also, we conclude that some agile practices should be used together in order to get better efficiency on cost and scope in four development aspects: improving (a)...

Due to the uniqueness of software projects there is no single Agile development approach that ideally fits all project contexts. Each software project is unique, whether in its subject area, development team, or project size. Because of this, adapting Agile practices according to project circumstances is a must. There has been a number of literature published discussing Agile practices adaptation...

For someone like me who never was part of the full design phase of the development process, I never knew the full concept of how the projects or applications were built from initiation. This assignment will allow me to have a high level understanding of the processes involved in system development, thereby allowing me to get a full grip of Project Management involved in the entire system development lifecycle. The 1st part of the assignment will allow me to identify and differentiate the 3 different development processes; waterfall, iterative and agile. I am hoping that after completing this part, I will somehow be able to identify the appropriate process for a particular application development. Among the 3 types of development approaches, the only one that I am familiar of is the waterfall approach. The 2nd...

...In 2001, there was a history-making conference of software-engineering thinkers in Snowbird, Utah. The product of that meeting was a remarkable document called the Agile Manifesto, a call to overturn many of the assumptions of traditional software development. I, in my capacity as one of the principal theoreticians of open-source development, was invited to be at Snowbird, but couldn't make it. Ever since, though, I've been sensing a growing convergence between agile programming and the open-source movement. I've seen agile concepts and terminology being adopted rapidly and enthusiastically by my colleagues in open-source-land — especially ideas like refactoring, unit testing, and design from stories and personas. From the other side, key agile-movement figures like Kent Beck and Martin Fowler have expressed strong interest in open source both in published works and to me personally. Fowler has gone so far as to include open source on his list of agile-movement schools. I agree that we belong on that list. But I also agree with Fowler's description of of open source as a style, rather than a process. I think his reservations as to whether open source can be described as just another agile school are well-founded. There is something more complicated and interesting going on here. and I realized when I read Fowler's description of open source that at some point I was going to have to do some hard thinking and writing in an effort to sort it all out. While doing research for my...

...SOFTWARE DEVELOPMENT: 1. Introduction Computers are becoming a key element in our daily lives. Slowly and surely they are taking over many of the functions that effect our lives critically. They are now controlling all forms of monetary transactions, manufacturing, transportation, communication, defence systems, process control systems, and so on. In the near future, they will be found in our homes, controlling all forms of appliances. Left to themselves, they are harmless pieces of hardware. Load the right kind of software, they can take you to the moon, both literally and figuratively. It is the software that gives life to them.When they are going to play such a crucial role, one small flaw either in the hardware or the software can lead to catastrophic consequences. The sad part is, while there are well defined processes based on theoretical foundations to ensure the reliability of the hardware, same thing can not be said about software. There is no theory for software devlopment as yet. But at the same time, it is mandatory that software always behaves in a predictable manner, even in unforeseen circumstances. Hence there is a need to control its development through a well defined and systematic process. The old fashioned 'code & test' approach will not do any more. It may be good enough for 'toy' problems, but in real life, software is expected to solve enormously complex problems. Some of the aspects of real life software projects are: Team effort: Any large...

...Optimization in Agile Data Warehouse Design Matteo Golfarelli, Stefano Rizzi, and Elisa Turricchia DEIS - Univ. of Bologna, V.le Risorgimento 2, 40136 Bologna, Italy {matteo.golfarelli,stefano.rizzi,elisa.turricchia2}@unibo.it Abstract. Agile methods have been increasingly adopted to make data warehouse design faster and nimbler. They divide a data warehouse project into sprints (iterations), and include a sprint planning phase that is critical to ensure the project success. Several factors impact on the optimality of a sprint plan, e.g., the estimated complexity, business value, and affinity of the elemental functionalities included in each sprint, which makes the planning problem difficult. In this paper we formalize the planning problem and propose an optimization model that, given the estimates made by the project team and a set of development constraints, produces an optimal sprint plan that maximizes the business value perceived by users. The planning problem is converted into a multi-knapsack problem with constraints, given a linear programming formulation, and solved using the IBM ILOG CPLEX Optimizer. Finally, the proposed approach is validated through effectiveness and efficiency tests. Keywords: Agile methods, Optimization, Data warehouse design. 1 Introduction As empirical studies suggest [9,2], agility is one of the most promising directions to overcome the problems of traditional software engineering approaches. The twelve principles stated in the Agile Manifesto [3]...

...HISTORICAL PROJECT 2570 bc The Great pyramid of giza completed The Pharaohs built the pyramids and today archaeologists still argue about how they achieved this feat. Ancient records show there were managers for each of the four faces of the Great Pyramid, responsible for overseeing their completion. We know there was some degree of planning, execution and control involved in managing this project. 208 BC Construction of the Great Wall of China Later still, another of the Seven Wonders of the World was built. Since the Qin Dynasty (221BC-206BC), construction of the Great Wall had been a large project. According to historical data, the labor force was organized into three groups: soldiers, common people and criminals. The Emperor Qin Shihuang ordered millions of people to finish this project. 1917 The Gantt chart Developed by Henry Gantt (1861-1919) One of the forefathers of project management, Henry Gantt is best-known for creating his self-named scheduling diagram, the Gantt chart. It was a radical idea and an innovation of worldwide importance in the 1920s. One of its first uses was on the Hoover Dam project started in 1931. Gantt charts are still in use today and form an important part of the project managers' toolkit. 1956 The American Association of Cost Engineers (now AACE International) Formed Early practitioners of project management and the associated specialties of planning and scheduling, cost estimating, cost and schedule control formed the AACE...
