– Access 4.0 | ONF Connect 2019 – Sept 2019 7Access4.0 is technology but also about change – some
lessons from an incumbent network provider ☺
Working agile (e.g. according to Scrum) is Software Implementation Architecture, code guidelines,
pretty rigid (meeting cycle, roles, …). 2-week requirements documentation etc. are project guidelines
sprints are tough – especially for those, who → be bold & strict!
are in touch with non-agile units
→ it’s all worth the effort; we get real
Code developed varies in quality
results quickly.
→ have empowered code maintainers in-
Transformation requires the right partners → be house
strictly picky about the right one; rather postpone
milestones
You can teach a network person IT, but becoming a
software engineer is a different thing
Scrum, SAFe, Nexus, … require new roles, → establish a nucleus of true IT people
processes etc. → Benefit from coaches
to help you to communicate and
practice over and over …
