By introducing a resource planning for the team, the smoothnes of implementation for projects has improved. The projectleaders now have a better idea of who is doing what. Also the team members experience this as very usefull.
With the idea of introducing a wiki based documentation system, the technical people got motivated to do documentation of systems and applications. This led to good documentation that is actually being maintained.
By the inhouse development of a CMDB (configuration management database) the important attributes of systems and applications have become centrally available. Not only the unix administrators can now use this to estimate impact when there is a problem, but also other departments can retrieve information about the complete installbase. Additionally the CMDB allows the team to guide onsite engineers to the location they have to be.

Working very directly with other operational departments like the NOC, Application maintenance group and the Database Administrator group.

Worked within the team on designing, implementing and taking into production an anti-virus and anti-spam system for the email service. Taking into account scalability, being easy to maintain and delivering the correct functionality.
Optimizing the tftp software when there were performance problems. A review of the sourcecode gave some indications of changes to be made. These changes led to a performance increase of a factor 100, which allow different processes within the company to work a lot faster and improve the quality of service towards the customer.
