KEGON : Vergleich agiler frameworks - by Kurt Jäger

185 views

Published on

"An agile report compares agile scaling approaches in terms of their market penetration. In Section 6, NEXUS is mentioned at 1% first time this year, LeSS loses 1% to 3% and SAFe is the clear market leader with 28%. Between the frameworks, there are often bitter discussions in the appropriate forums on the Internet, who advocates the better scaling approach. This is in my opinion, but an unnecessary disgusting discussion, because
1. The differences in each implementation of a framework are strongly influenced by the corporate culture.
2. Frameworks are customizable by definition.

I therefore would like to deal with commonalities and the main emphasis of the three scaling methods.
It is e.g. an essential difference whether:
1. Three teams of seven developers working on one product - ,
or several 100 employees creating a solution with integration of hardware and software or the involvement of (agile) suppliers
2. The enterprise portfolio management should be agile.
3. The Scrum teams should be organized over a long-term budgeting along the Valuestreams.
4. The goal is to scale agile in a startup or in a young company. - or a classic enterprise like LEGO wants to be agile."
