At the end of 2007 it was decided that Statoil would merge with Norsk Hydro's Oil & Energy division into a new company, StatoilHydro, later to become Statoil. This required the transfer and merge of Hydro O&E's existing systems and infrastructure into Statoil's, consisting of around 6000 PC users, 1300 servers, 400 applications and 80 TB of data. At the same time harmonising the two environments and removing redundant infrastructure and applications.
While the migration was taking place, it was paramount to maintain operational stability in order to avoid impacting normal business operations. Nonetheless the migration should also be executed as quickly as possible in order minimise the time and therefore cost associated with operating duplicated environments.
In terms of size and complexity, this was Norway's largest ever IT project at the time. Our long and successful experience of handling similar processes was probably one of the reasons why EVRY was chosen to run the program “Exit Management”, initiated after the initial integration project.
Whilst EVRY took the lead for the formal program and project management, the process required a very close and precise coordination with Statoil's IS/IT and business organisation. Together we defined and agreed upon what should be changed or removed, how and when it should be performed. It was this trustful close cooperation between the different parties that was key to ensuring the success of the project. EVRY also acted as an advisor to help balance conflicting requirements for simplifying and harmonising the IT system landscape by keeping operational stability.
In total the program handled over 240 individual "exit notes" and at its peak involving 11 EVRY project managers and more than 120 EVRY personnel executing the changes. All the changes were executed according to Statoil's own processes and utilising their systems and tools.
As a result of the Exit Management process, Statoil and EVRY have managed to:
The Exit process has been executed with minimal disruption to business operations or unplanned downtime of the affected systems. The exit program has resulted in cost reduction, followed-up professionally by EVRY, with clear KPI reporting.
Whilst cost reduction was a primary aim, other benefits as a result of the process include a simplified system landscape with increased application transparency and a harmonised user experience – same access interface and processes, regardless of whether system came originally from Hydro or Statoil.
