Holger Christen Ølholm's Summary

Technical project manager with PRINCE2® Foundation certification and 16 years of international experience in the implementation of technically complex solutions

Types of projects where I can contribute as technical project manager:

• mobility – iPhone/iPad – infosec, roaming and support/operations/service delivery processes
• technical specifications, design and technology and vendor selection
• telephony (VoIP/ISDN), data centre, IP networks, OS, applications, monitoring & IT security
• change and configuration management (CMDB)
• technical and operations documentation
• disaster recovery and business continuity planning
• interoperability and acceptance testing of telephony hardware and software

How I am professionally:

I possess 16 years of technical project management experience within IT and telecom along with implementation of technically complex solutions. I have also worked as a specialist. I constantly maintain and expand my technical knowledge, in order to remain innovative and understand the technologies I work with and the specialists I lead. My goal is to ensure that the total technical and people skills are sufficient in order to deliver solutions required by the business.

I am good at turning chaos into structure, and I work independently and enjoy being in the leadership role. I am inpatient and persistent and this gives me the strength and drive that I require to achieve results and overcome challenges.

Before I start on a project, I interview the stakeholders in order to identify among other things, the goals, mood, expectations, status and risks. My experience has taught me that this legwork can improve communication, create goodwill and avoid the waste of resources, hence increasing the probability of the project’s timely success.
