    How do we do the culture change within a Telco organization to adopt software-ization (SDN, NFV, Virtualization and Cloud) in a more sustainable way?

    That was nice topic and important for all telco. In Ethio telecom also deploy many systems like ERP and fraud and revenue assurance tools in order to improve efficiency and increase profitability.

    Anuradha,
    Quite and interesting and important question. Indeed it's a cultural change. Few thoughts that may be worth considering and useful:
    1. From Requirements, Design, Development, Test and Deployment stand point : need to imbibe "DevOps" culture. Going forward, CI/CT/CD has to be a part of life. May arrange training sessions on DevOps and drive tools automation to implement it e.g. may consider FusionForge, Jenkins, Maven, Subversion, SonarQube, Git, Puppet etc. which are all open source.
    2. From Operations stand point : Need to add skills such as Heat Orchestration Templates, TOSCA, Python scripting etc. 
    Hope this helps.

    The topic is indeed a very relevant one and an aspect that is quite often prone to being ignored while the organization focuses on technological shift/progress.

    Besides the views added already regarding imbibing DevOps in the way of work, the shift in cultural direction of the organization relies a lot on management behaviours. There is hardly a stimulus as effective as walking the talk. People tend to observe and note the subtle changes in the way things are discussed and handled by the leaders in an organization. These subtle indications go a long way than any memo or email communication.

    At the same time, for the cultural shift to be effective, it is very important that support functions are onboard and fully aligned. These can be the finance or HR where the processes, if not revamped for the new culture, could become a hurdle.

    I believe the culture change would be a gradual process as this would involve a change of mentality from operations perspective.

    As an example, looking at ‘Closed Loop Automation’ scenario, the solution maturity would impact mindset of operators to trust a software recommended change to network configuration, which may impact their business critical services.

    The impact of virtualisation and software technologies on Workforce has been explored in two published  ZOOM Project documents
    IG1132 Digital Services Consumer Workforce Transformation R15.0.0
    and an update based on experiences n applying these techniques has been published in
    IG1148 Communication Services Provider Workforce Transformation Implementation Experience R16.5.0
    This last document  is being re-visited in the ZOOM Project Operations Center of the Future team  as part of Relase 17


    The  Digital Maturity Model & Metrics Project  is addressing the dimension of transformation to identify metrics than can be used by service providers to assess progress.  

    It would be great to get the additional insight of this community into these two projects to help drive these and other publications forward. and also critique the current results on the community.

    Hi,

    We're usually talking about this topic at a high level: organizational transformation, culture change, orchestration, etc. ... My question is if we know somebody who's really working on 'virtualizing the functionality of a network'. What kind of network elements are already virtualized right now? 

    Thanks in advance !!

    Hi Daniel,

    practically everything can be virtualized and appliad in the network using SDN-Openflow if the switch supports it, or if it is a an NFV infrastructure it can just run it as VNF. VNF can be anything, e.g. Firewall, Router, Database etc.
