Agile development methodology
Agile development is a system development strategy where the system developers are given the competence to choice from a wide selection of appropriate tools and techniques that can be used when accomplishing a certain task on hand. Agile methods are the integration of different kinds of approaches of system analysis .Design application is considered suitable to the problem that is being solved and the system being developed. It also focuses on different aspects of the software development cycle. Agile methods are also known as agile methodologies.
According to (1):
“agile methods or agile methodologies are a software developing method that is people focused communications- oriented, that is flexible ( ready to adapt to expected changes at any time), speedy , lean (shorting timeframe and costs on Improved quality), responsive and learning ( focused on improvement during and after product development)”.
You get many different types Agile Methodologies such as scum, XP, DSDM which are popular agile methodologies.
Scum is the most popular way to introduce agility because of its simplicity and flexibility. It’s the most popular adopted agile method .It is an agile development method which is mainly concerned particularly on how to manage tasks in a team based development environment. According to (2) :
Scum was developed by Jeff Sutherland & Ken Schwaber. This method involved one or more small teams that work ...

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
SDLC( Software Development Life Cycle) , is a process used by the software industry to design, develop and test high quality software .The SDLC aim to produce good quality software that meets or exceeds the user’s expectation and reaches completion within time and cost estimates.

TRIARQ Healthcare Agile development is not a methodology in itself. It is an umbrella term that describes several agile methodologies. At the signing of Agile Manifesto in 2001, these methodologies included Scrum, XP, Crystal, FDD, and DSDM. Since then, lean practices have also emerged as a valuable agile methodology and so are included under the agile development umbrella.
This principle is the core component of all of 5 principles, because we can say that a big part of lean startup method and the succes rate of this method is determined through this principle. It covers all the topics including transforming ideas into businesses, assess and measure the metrics and testing these metrics.
When implementing a new software program, there are different approaches which can be used to manage the project. One of the approaches is the Scrum approach which is an agile method focusing on managing the iterative development instead of specific technical approach. According to Sommerville (2011), the agile method uses incremental development methods for small systems and gives user access to new sections every few weeks based on feedback to make changes, (p 58). With the Scrum approach, there are three phases where the project is outlined, then sprint cycle which is a repetition of tasks to complete the project, and then project closure. With using the sprint cycle of the Scrum approach, a tasked is reviewed and priorities are set and the requirements are introduced. Then the project team works with the customers to select the part of the system to be worked on. After the selection process, the software is developed and then reviewed. After the software has been reviewed, the next cycle starts from the feedback to make changes or add more features to the software. With the new system for the education institution, the first pa...
What technique or strategy would you apply to evaluate the effectiveness of your development processes?
As per Boehm and Turner concepts of balancing agility and Discipline six exemplary conclusions were made, of which first one is that neither agile nor plan-driven processes and methods provide a silver bullet which implies that either of the agile or plan-driven approach is not applicable in all situations. Both the processes deals with the essential software engineering complications like complexity, changeability, invisibility and conformity while both the processes have its own advantages and disadvantages. Agile method to some extent achieves changeability and invisibility as the project’s strategies and its implementation is discussed and shared among all the members of a team whereas it fizzles to handle complexity of the project and conformity. Also agile method fails in scaling up to large complex projects. Plan driven concepts handle conformity and invisibility as thorough documentation and extensive planning is done. But it fails in handling changeability as it is difficult to do re-documentation every time and also fails to handle increasing complexity as new systems are added which involves enterprise integration. Hence it can be said that neither agile nor plan-driven processes provide silver bullets instead they can be termed as lead bullets individually.
In today’s dynamic business environment, where there is need to be on par with changing business requirements and the needs of users to survive in the market, it is advisable to adopt a flexible and effective software development approach. An Agile approach as opposed to other development methods, enables organizations to respond fast to changes, gaining competitive advantages on the market and ensures user satisfaction too. ‘A system development methodology refers to the framework that is used to structure, plan, and control the process of developing an information system. (CMS & HHS, 2008)’. Several software development methodologies have emerged over years each having its own benefits and weaknesses and each of which works well for certain kinds of software development projects, teams and contexts. But a development methodology is necessary to make a development process productive, manageable and measurable and it defines specific deliverable and artifacts
The Waterfall Model has been the ideal choice for software development. In this model, an idea become a usable software in a sequential process that cascade through the stages of Initiation, Analysis, Implementation, Testing and Maintenance. But it has some disadvantages. Agile software development evolved as a solution to the disadvantages of Waterfall model. Instead of a sequential design process, the Agile methodology follows an incremental approach.

A Software Development Model is a framework that is used to structure, plan, and control the process of developing an information system. These are various processes or methodologies that are being selected for the development of the project depending on the project’s aims and goals. There are many development life cycle models that have been developed in order to achieve different required objectives. This report aims to compare the following software development models: Waterfall, Prototyping, Rapid Application Development (RAD), and Agile.
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.
