Advantages And Disadvantages Of Agile BI

This review and evolution process is repeated as many times as needed, until the final Formal Spec is produced, or the SRS. Then programming can begin. “The process of writing a requirements specification usually requires frequent communications between the developer and the client, keeping the structure of the specification clear and the statements or expressions used readable is therefore crucial”(Lui et al.).

These user stores are then arranged into a list known as a Backlog. The Backlog is then prioritized based on what the customer and product team feels is the more important features to be implemented. The development group is then divided into Scrum Teams of about 7 – 10 members which include both developers and test engineers. The team commits to working on a number of Stories that can be completed in a 2 week development cycle known as a Sprint. Once the Sprint is completed the team will have created working software that the customer is then able to use and provide feedback.

Many business use the agile organizational methodology. As they require the ability to remain flexible, enduring ever-changing requirements. The agile organization develops more mission-critical, high-profile systems. Sharing responsibility within small teams (of 15 or less) is also a main principle of an agile organization. Never is a hierarchy design operational in the agile organization, as the group possess the ability to over ride decisions made by management. The agile type of organization displayed itself over time as an entrepreneurial type of organization providing the high-speed changing rather than the standardization of a bureaucratic organization (Johnson, Jackson, & Burrows, 2011).

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

The project will be managed using a modified waterfall technique. In this approach, the initial two phases of the

The current development process devotes a large amount of time at the front end of development to establishing customer needs and converting them into system level requirements. The client-site team meets with customers, learns their needs, develops specifications, verifies them with the customers, and then sends them offshore for development. This is a very formalized, documented process. (+)

“Agile” was first introduced in 2001, by a team of software engineers looking to improve their adaptiveness and responsiveness to ever-changing requirements. Not knowing where to begin, the team began by formulating principles, which they would use to guide their new development process. Which, in turn, lead to the creation of the Agile Manifesto, and thus a new methodology was born.

Thus, Agile came into play. This is a faster and smaller method over traditional. Stakeholders get together with small teams to look at cost, resources and expected time frames. This team figures out the computer verbiage, checks and balances, verification coding, iterations, number limits, scripts, all in the early stages of development.

Within agile development, Scrum groups are maintained by two specific parts. The main is a ScrumMaster, who can be thought of as a lead for the group, helping group members use the Scrum procedure to do at the maximum level.

The company has no methodology. You really do not have any processes or frameworks in place and departments or teams do projects different every time with varying results.

Scrum: Scrum is management framework under agile for iterative and increment product development. Scrum consist of Three characters and various meetings to take care of following things. Increase the quality of the deliverables; cope better with change (and expect the changes);

Unlike waterfall development methodology, agile foresees the documentation but is initially unwilling to adapt such as adding a lot new facets to the development model. Gabe, M. said, "Agile methodologies attempt to capture and use the dynamics of change inherent in software development in the development process itself rather than resisting the ever-present and quickly changing environment.". Demand of traditional methods complete and accurate requirement before the development; agile methods presume that change is strict, unavoidable and must be embraced throughout the cycle of product development. Cao, L. and Ramesh, B. believes individuals who fill those roles are much more important than the roles that people fill. Fowler also believes that each talented individual brings something unique to a team that are developing the system and disagrees with the application of engineering

Honda is a well-known global manufacturer of automobiles and motorcycles. This means that its contemporary information system is highly-organized for collection, organization, storage, exchange, and communication of useful information. This efficient system helps support its business operations, and decision-making. To facilitate the flow and take advantage of modern information system, a number of development approaches and methodologies have been introduced. The waterfall approach, iterative approach, and agile approach are some examples of them.

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

Many of the software companies adopt waterfall methodology for their project. Waterfall methodology follows the below steps:
