POINTS POSSIBLE: 100
OVERVIEW: Hy-Vee Corporate headquarters is based in West Des Moines and is an employee-owned supermarket. As of 2015, Hy-Vee has 233 stores across eight Midwestern states and $6.9B in annual revenue.
The article Scope Management in Agile Versus Traditional Software Development Methods (Israr Ur Rehman, et al, October 2010, NSEC ’10: Proceeding for the 2010 National Software Engineering Conference) discusses the importance of scope management, it’s role and impact on a project, and how it alone can lead projects toward failure. “A well-defined and well managed scope is very important for a qualitative, cost effective and timely completion of the project (page 1). The replacement of traditional software development (Waterfall) by agile software development methods is very apparent in cost, resources and time for the work.
Cost and resource needs are higher for traditional than Agile due to Waterfall’s sequential development phase of all requirements determined in the beginning, software design and finally implementation of master design. The need for all information up front takes substantial time to gather and the sequential design does not allow for project changes as the flow enters into the programming stage. With Agile, costs remain low because there exists an incremental and iterative approach to the project, meaning less time is used to collect all requirements up front, the

Scope Management is the collection of processes which ensure that the project includes all the work required to complete it while excluding all work which is not necessary to complete it. The Scope Management Plan will detail how the project scope will be defined, developed, and verified. The Scope Management plan will also defines who is responsible for managing the projects’ scope and also acts as a guide for managing and controlling the scope through the entire project.
First, let’s take a look at Agile, in particular the role of scope. Several traditional software development models came about in the 1960s, such as incremental, spiral and waterfall modelling. Over time it was realized that the software development team did not realize all of the needs up front. Thus, the customer was was not delivered what was expected. It’s essential to have an outline of who, what, when and where but this is often a transforming list.
The Agile Methodology Principles makes the development much faster because the primary importance is given to the customer satisfaction and continuously delivers product. Even though requirements change at the ending phase the product is developed. The Agile development insist the self-organizing team which can create requirements, best architectures, best models. The Agile development promotes a distinct way of thinking to build things and methods to deliver continuous improvement of product. It facilitates to make best practices and decisions together. It a development to promote the adaptive planning, continuous improvement, evolutionary development and delivery, and required time to complete work. It encourages for rapid response to change in the whole development cycle. The project team prefers agile development to move in a creative and quick way. The project progress also depends on working software and project environment and support is provided and built by the individuals. They promote the sustainable environment. Constant attention is provided to the technical excellence and best models are given by the agile methodology. This principle helps the project team members
Despite the closure of many of HMV’s stores due to administration difficulties, over 100 stores were still in operation in prime shopping locations in the UK and Ireland. In 2012 HMV had nearly 20% of the market share, slightly more than Amazon at the time. HMV is one of the largest and most successful entertainment retail store in Europe and is more successful than its rivals such as Virgin megastore who closed down in Ireland in 2002. (McCaughren, 2007). As of 2013 HMV had 16 stores operating all over Ireland in the main cities such as Henry Street, Lucan , Graton Street, Galway and Cork. (www.thejournal.ie). In Ireland HMV’s physical presence is strong compared to their rivals Tower
One of the initial steps in researching a problem is to know exactly what the problem is and compose a problem statement that unambiguously identifies and defines the problem to research. Sekaran (2003) said, “No amount of good research can find solutions to the situation, if the critical issue or the problem to be studied is not clearly pinpointed” (p. 69). The area of research for this paper focuses on software development, in particular, the study of agile software development methodologies and if these methodologies are successful in delivering software on time, within budget, and includes the requested features.
Using the Agile approach enabled us to organize the software project into chorological order from the User Requirements to the End product. The requirements were formed by meeting our client Fernando on regular bases discussing the requirements of the program. He would assure
Scope is nothing but which refers to project boundaries where it determines what work will be completed during the project lifecycle. This even includes identifying the work which would not be included in the current round of product or service development. A scope in a project is nothing but the proper planning which is made for the project which involves in determining and even documenting a list of specific project goals, deliverables, tasks and deadlines. The documentation which is made for the scope of the project clearly explains the boundaries of a project and also establishes the responsibilities for each team member and sets up procedures for how much the completed work will be verified and approved. The scope of the project which is made helps the project team remained focused on the given task. The scope statement also provides the project team leader or the facilitator with guidelines for making decisions about the change of request which are being made during the implementation of the project. it would be better if the project has a proper scope at the beginning or initial stages itself as it is quite natural for large projects to their parts along the way. when documenting the scope of a project the stake holders should be very specific regarding their work as one or more parts of a project ends up requiring more work, time, effort because of poor planning or miscommunication Effective scope management requires good communication in order to
From my perspective, though not being privy to a genuine cost analysis, yet being well versed in areas that do impact our financial well-being – most notably where challenges in back-end scenarios could be met more immediately and internally rather than hired out and realized on an external vendor’s own timeline – I will provide an analysis that clearly displays the benefits of agile methodology over our current use of waterfall. With this essay, I intend to provoke change, though I do understand that further consideration and discussion will be required prior to any realization of meaningful change.
Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders [1].
Software development is a field where developers thrive to provide products faster, better and very inexpensive methods. “Agile Development” term used for several iterative and incremental software development methodologies. Each agile method is unique in its approach, they all impart a typical vision and core attributes. As matter of fact all the methods are fundamentally incorporate with each other and having a review system provides successive ways to enhance, refine and deliver a software system. The below figure represents the steps followed in agile development
Compared to the agile, another famous software development mode called waterfall is driven by technique documents and this mode require the team to write a lot of requirement documents containing all the requirements to a certain software. It is written to allow people to understand what software should do. So the developers will develop the functions of software according to the documents strictly. But the agile software development just focuses on the necessary document. It is avoid taking a lot of time to write the requirement documents. Its opinion is that the face to face communication between the human is the most important thing. So the agile think the human is
Due to its characteristics, the Waterfall method has some really good advantages towards it. First of it, the client knows what to expect. After all the requirements gathering and analysis a well estimated project is presented, with a good idea of the size, cost, and timeline for the project. More than this, the client will have a definite idea of what their program will do in the end. Secondly, its meticulous record keeping allows the ability to improve the existing program in the future, and because of waterfall’s strong documentation it allows for minimal project impact when facing an employee turnover. These two main points, predictability and well-documented projects are the Waterfall flagship in an industry that pursue the best cost
This essay involves the comparison and contrast of the different methodologies used by programming teams. Among these methodologies are; System development life cycle (SDLC), Extreme programming and Agile methodology. Software development methodologies are the frameworks involved to structure, plan and control the processes used in developing an information system. The system development life cycle (SDLC) is a conceptual model which is involved in most project management and used for large scale projects with relatively large number of developers. A good example of SDCL methodologies includes; waterfall model. The SDCL takes a lot of time to produce complete products but of high quality. Agile methodology is a conceptual framework used also in project management and it is designed for small projects with few developers. Extreme programming on the other hand allow for communication with customers and by doing so it ensures interaction between developers and consumers in order to change as fast as the customers' needs and desires changes. Even though there different methodologies, agile methodologies seem to have a lot of advantages over the Extreme programming and system development life cycle. Since it combines a number of other methodologies to come up with a better way for developer to produce faster and change to as customers desires changes.
Agile methodology follows iterative development method which make it more suitable to use for light weight projects where the changes are frequent. Waterfall on other case is a heavy weight methodology with no changes or iterations allowed once the project starts. Here the requirements are fixed and any change later is not accommodated and will be considered as a new project. Both the methodologies are adopted for a project based on its type and requirement. In this paper We have applied both Waterfall and Agile methods to a Service Delivery platform project of a telecom company to come up with an individual project plans
