The Role of the Architect(ure) in the Digital Product Development

The Role of the Architect(ure) in the Digital Product Development

Das Informationszeitalter hat vieles auf den Kopf gestellt, unter anderem auch die Anforderungen an Unternehmen. Um für Kunden relevant zu bleiben, müssen sich diese kontinuierlich neu erfinden. Dieser stetige Wandel hat nicht zuletzt auch Einfluss auf die Software und Systeme sowie die Personen, die diese entwickeln. Eine dabei bedeutende Aufgabe kommt den (Software-)Architekten zu. Der Vortrag geht auf die Besonderheiten der Produktentwicklung in Digitalunternehmen ein.

Ausgehend davon, was dieses Umfeld auszeichnet, wird die Rolle des Softwarearchitekten abgeleitet und zu gängigen Rollendefinitionen sowie anderen Industrien abgegrenzt. Dabei wird auch darauf eingegangen, mit welchen modernen Methoden Unternehmen (und insbesondere die Produktentwicklung) diesen Anforderungen begegnen, warum sie selbst für dieses Umfeld oft nicht weit genug gehen.

Anhand von zwei Praxisbeispielen wird die Theorie auf die Realität angewandt. Dabei wird jeweils auf die spezifischen Problemstellungen, Lösungsansätze sowie die Rolle des/der Architekten in diesem Kontext eingegangen.

  3. "The highest level concept of a system in its environment.

    The architecture of a software system (at a given point in time) is its organization or structure of significant components interacting through interfaces, those components being composed of successively smaller components and interfaces." – IEEE Recommended Practice for Architectural Description, IEEE Std P1471 "In most successful software projects, the expert developers working on that project have a shared understanding of the system design. This shared understanding is called ‘architecture.’ [...] These components are usually composed of smaller components, but the architecture only includes the components and interfaces that are understood by all the developers." – Ralph Johnson "Architecture is about the important stuff. Whatever that is." – Who needs an architect?, by Martin Fowler "Stuff that's hard to change later." – Neal Ford Software Architecture
