What Is Scrum? According to the State of Agile Survey, approximately 60 percent of projects are Agile.1 After all, Agile frameworks help companies accelerate time to market, increase productivity, and respond to changes in priorities. Of all the Agile frameworks, Scrum is the most widely adopted. Professionals from around the world and in a variety of industries are using Scrum to position their teams for greater success. Join the global movement that is transforming the world of work, and bring Scrum to your workplace. To bring Scrum out of the classroom and into practice, you'll need a Certified Scrum Coach (CSC). CSCs are experts in both the theory and practice of Scrum. Certified Scrum Trainers (CSTs) are licensed to teach Certified ScrumMaster® (CSM) and Certified Scrum Product Owner (CSPO) courses within your workplace environment. 1 VersionOne.
Extreme programming Planning and feedback loops in extreme programming. Extreme programming (XP) is a software development methodology which is intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, it advocates frequent "releases" in short development cycles, which is intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted. Critics have noted several potential drawbacks, including problems with unstable requirements, no documented compromises of user conflicts, and a lack of an overall design specification or document. History Although extreme programming itself is relatively new, many of its practices have been around for some time; the methodology, after all, takes "best practices" to extreme levels. Origins The first time I was asked to lead a team, I asked them to do a little bit of the things I thought were sensible, like testing and reviews.
What is SCRUM? Contents Introduction SCRUM is a loose set of guidelines that govern the development process of a product, from its design stages to its completion. It aims to cure some common failures of the typical development process, such as: Chaos due to changing requirements - the real or perceived requirements of a project usually change drastically from the time the product is designed to when it is released. SCRUM has been successfully employed by hundreds of different companies in many different fields, with outstanding results. You will find many similarities between SCRUM and Extreme Programming, but one of the major differences is that SCRUM is a fairly general set of guidelines that govern the development process of a product. SCRUM Values The SCRUM values are derived from the Agile values of software development. The SCRUM Process Figure 1: General SCRUM Process The scrum process has 3 main phases. Planning In this phase, the project is planned and high-level design decisions are made. Closure
Scrum Methodology & Agile Scrum Methodologies Scrum (development) Scrum is an iterative and incremental agile software development framework for managing product development. It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project. A key principle of Scrum is its recognition that during a project the customers can change their minds about what they want and need (often called "requirements churn"), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. Later, Schwaber with others founded the Scrum Alliance and created the Certified Scrum Master programs and its derivatives. Each sprint is started by a planning meeting.
Project Lifecycle Models: How the differ and when to use them Business eSolutions provides System Development Project Management services, Problem Project Diagnostic and Recovery services and Project Management Training and Facilitation courses covering strategy, project management, project estimating, business requirements, risk management and quality assurance. We can help you define a lifecycle methodology customized to your organizational strengths and development risks. Our mission is to help our clients produce quality systems on time and on budget. 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. The following describes standard project lifecycle models, and reviews their strengths and weaknesses. Pure Waterfall • Spiral • Modified Waterfall • Evolutionary Prototyping • Code-and-Fix Staged Delivery • Evolutionary Delivery • Design-to-Schedule • Design-to-Tools • Off-the-Shelf What model do you use?

Agile software development Agile software development is a set of principles for software development in which requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development, early delivery, and continuous improvement, and it encourages rapid and flexible response to change. Agile itself has never defined any specific methods to achieve this, but many have grown up as a result and have been recognized as being 'Agile'. The Manifesto for Agile Software Development, also known as the Agile Manifesto, was first proclaimed in 2001, after "agile methodology" was originally introduced in the late 1980s and early 1990s. The manifesto came out of the DSDM Consortium in 1994, although its roots go back to the mid 1980s at DuPont and texts by James Martin and James Kerr et al. History Incremental software development methods trace back to 1957. In 1974, E. The Agile Manifesto Agile principles
Kanban This article is about the process management and improvement method. For the lean manufacturing process, see Kanban. Kanban in the context of software development can mean a visual process management system that tells what to produce, when to produce it, and how much to produce inspired by the Toyota Production System and Lean manufacturing. The name 'Kanban' originates from Japanese[看板], and translates roughly as "signboard" or "billboard". It was formulated by David J. Start with existing process The Kanban method does not prescribe a specific set of roles or process steps. Agree to pursue incremental, evolutionary change The organization (or team) must agree that continuous, incremental and evolutionary change is the way to make system improvements and make them stick. Respect the current process, roles, responsibilities and titles It is likely that the organization currently has some elements that work acceptably and are worth preserving. Leadership at all levels 1. 2. 3. 4.
Lean Lean software development (LSD) is a translation of lean manufacturing and lean IT principles and practices to the software development domain. Adapted from the Toyota Production System, a pro-lean subculture is emerging from within the Agile community. Origin The term lean software development originated in a book by the same name, written by Mary Poppendieck and Tom Poppendieck. The book presents the traditional lean principles in a modified form, as well as a set of 22 tools and compares the tools to agile practices. Lean principles Lean development can be summarized by seven principles, very close in concept to lean manufacturing principles: Eliminate waste In order to eliminate waste, one should be able to recognize it. A value stream mapping technique is used to identify waste. Amplify learning Software development is a continuous learning process with the additional challenge of development teams and end product sizes. Decide as late as possible
Agile Architecture: Strategies for Scaling 1. Towards Agile Architecture Architecture provides the foundation from which systems are built and an architectural model defines the vision on which your architecture is based. The scope of architecture can be that of a single application, of a family of applications, for an organization, or for an infrastructure such as the Internet that is shared by many organizations.Regardless of the scope, my experience is that you can take an agile approach to the modeling, development, and evolution of an architecture. Here are a few ideas to get you thinking: There is nothing special about architecture. 2. Figure 1. Figure 2 depicts the agile/basic lifecycle described by the Disciplined Agile Delivery (DAD) framework. Figure 2. An alternative to this light-weight approach to initial architecture modeling, is to attempt to define your architecture completely before implementation begins. 3. This question is more complex than you think. Sometimes people don't agree. 4. 5. Figure 3. Figure 4. 6.
