As the solution is very important for Nykredit the testing phase was prioritised to secure all areas were tested thoroughly. The process required close coordination between users, administrators and consultants, which was a challenge due to different work schedules.
In the old setup, Nykredit had four different environments to support the EPM Process: Dev, Test, Pre-Production and Production. With the new setup in place, this was consolidated down to a total of two environments. With several environments, the level of security in each environment can be fairly simple, but with two consolidated environments the level of complexity rose with the demand for more control in user management. inlumi helped Nykredit to set up a security structure for the new environment to get better insight and to simplify the process.
One other challenge was the huge complexity of the upgrade due to the significant change in infrastructure, processes and integration tools. Nykredit expressed that it was one of the largest and most complex upgrades ever. Several stakeholders were involved which required an experienced project manager and skilled resources being able to look beyond their own area of responsibility. A constant focus, planning ahead and dedicated resources made the difference between failure and success.
