Principles behind the Agile Manifesto We follow these principles: Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. Business people and developers must work together daily throughout the project. Build projects around motivated individuals. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. Working software is the primary measure of progress. Agile processes promote sustainable development. Continuous attention to technical excellence and good design enhances agility. Simplicity--the art of maximizing the amount of work not done--is essential. The best architectures, requirements, and designs emerge from self-organizing teams.
Scientist creates lifelike cells out of metal Scientists trying to create artificial life generally work under the assumption that life must be carbon-based, but what if a living thing could be made from another element? One British researcher may have proven that theory, potentially rewriting the book of life. Lee Cronin of the University of Glasgow has created lifelike cells from metal — a feat few believed feasible. The discovery opens the door to the possibility that there may be life forms in the universe not based on carbon, reports New Scientist. Even more remarkable, Cronin has hinted that the metal-based cells may be replicating themselves and evolving. "I am 100 percent positive that we can get evolution to work outside organic biology," he said. The high-functioning "cells" that Cronin has built are constructed from large polyoxometalates derived from a range of metal atoms, like tungsten. The metallic bubbles are certainly cell-like, but are they actually alive? The early results have been encouraging.
Kanban et Scrum - tirer le meilleur des deux Ce livre fait partie de la collection de livres InfoQ "Enterprise Software Development". Avec ce livre, vous apprendrez ce qu'est Kanban, ses forces et ses limites, et quand l'utiliser. Vous apprendrez également comment Kanban peut améliorer Scrum, ou tout autre outil que vous utilisez, et à quel moment c'est possible. Henrik montre clairement que le plus important n'est pas l'outil avec lequel on commence, mais la façon dont on améliore constamment son utilisation et comment on développe progressivement son ensemble d'outils. Mary Poppendieck, auteur de plusieurs livres de référence sur le Lean Software Development. Je suis très heureux qu'Henrik Kniberg et Mattias Skarin aient émergé comme des leaders dans ce domaine.

Stem Cell Basics: Introduction Laboratory studies of stem cells enable scientists to learn about the cells’ essential properties and what makes them different from specialized cell types. Scientists are already using stem cells in the laboratory to screen new drugs and to develop model systems to study normal growth and identify the causes of birth defects. 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
Sassafras Software L'Extreme Programming Depuis les débuts de l'informatique commerciale dans les années '60, plusieurs méthodologies de développement de logiciel ont vu le jour. Le modèle en cascade et ses dérivés ont connu un grand succès, mais leur lourdeur et rigidité sont de sérieux handicaps. Extreme Programming propose de remplacer certaines notions acquises par des idées révolutionnaires, et de rendre le développement de logiciel efficace et agile. I-A. La petite histoire d'une grande industrie▲ L'histoire du développement de logiciels est intimement liée à l'histoire de l'industrie informatique. I-B. Le transistor a été inventé en 1948, et l'ordinateur sous sa forme actuelle existe depuis les années '50. Les années '70 ont vu l'apparition des langages C, Pascal et Basic, de Unix, du circuit intégré, de Apple, Intel et Microsoft, et des premiers micro-ordinateurs. I-C. Des méthodologies de développement sont apparues à différents moments durant la révolution informatique. I-D. II-A. II-B. III-A. III-B. III-C. III-D.
Garage Games Visualizing Agile Projects using Kanban Boards In Agile projects, it's a common practice to visualize and share project status in “big visible charts” on a wall of the project room. Lean systems also use such devices. "Kanban," in Japanese means, loosely translated, 'card or sign'. In a Lean production system, Kanban is a method which uses standard units or lot sizes with a single card attached to each. A new card is "pulled" into the system only when the work represented by an "in progress" card is completed.. In this paper, I explore visualization methods found widely in agile projects these days, and then propose using Kanban Boards to organize three viewpoints (Time, Task, and Team) so that the whole team understands the current status of the project and can work in an autonomous, motivated and collaborative manner. Visualization in Agile Projects XP has a practice called “informative workspace” where you can see how the project is going on at a glance [Beck05].
