OpenTuesday: Aktuelle Standards der agilen Softwareentwicklung

908 views

Published on

Dieses OpenTuesday-Referat von Michael Palotas ging gezielt auf die sogenannten «Agile Engineering Practices» ein und zeigte anhand praktischer Beispiele auf, wie die Anwendung dieser Praktiken als Enabler für agile Softwareentwicklung fungieren.

Es gibt wohl kaum eine Firma, bei der agile Softwareentwicklung kein Thema ist. Viele Organisationen haben sich schon auf den Weg begeben, agil zu werden. Im ersten Schritt bedeutet dies in der Regel, die Prozesse auf eine agile Methodik wie z.B. SCRUM zu ändern.

Auf der Strecke bleiben jedoch oft die (agilen) Entwicklungs-, Test- und Liefermethoden wie Continuous Integration, Test-Automatisierung, Test Driven Development, Pair Programming etc., die eine agile Vorgehensweise erst richtig ermöglichen.

  12. 12. WHAT  IS  CONTIUOUS  INTEGRATION?     12 Continuous integration (CI) is the practice, in software engineering, of merging all developer working copies with a shared mainline several times a day. It was first named and proposed as part of extreme programming (XP). Its main aim is to prevent integration problems, referred to as "integration hell" in early descriptions of XP. CI can be seen as an intensification of practices of periodic integration advocated by earlier published methods of incremental and iterative software development, such as the Booch method. CI isn't universally accepted as an improvement over frequent integration, so it is important to distinguish between the two as there is disagreement about the virtues of each. GRIDFUSION
  13. 13. WHAT  IS  CONTINUOUS  DELIVERY?     13 Continuous Delivery (CD) is a design practice used in software development to automate and improve the process of software delivery. Techniques such as automated testing, continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed to test environments, resulting in the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead. The technique was one of the assumptions of extreme programming but at an enterprise level has developed into a discipline of its own, with job descriptions for roles such as "buildmaster" calling for CD skills as mandatory.
