Step #1: Map your IT environment
IT environments consist of software and hardware assets, licenses, servers and user accounts to mention a few. Before you can begin to lower your costs you have to be aware of the exact components that your IT environment consists of. Larger organizations have several teams to take care of various parts of the infrastructure. Smaller organizations, however, have one or a couple of people who are responsible for all components of the IT infrastructure. Regardless of how you divide the responsibilities the probability that you have a total insight into all changes that are occurring in your IT environment is quite small.
The first step to reduce your IT costs is therefore to carefully map your IT environment so that you know the exact components that it is constituted by. Here you can also get to know which parts are cost bearers.
Step #2: Identify dependencies
The components of the IT environment do not exist in a vacuum. On the contrary most parts of your IT infrastructure are dependent on each other. You can identify dependencies by asking questions such as: What will happen if we remove this server from our production environment? or What are the consequences of merging these two databases?
To investigate dependencies will simplify making decisions in regards to which components no longer contribute. By understanding the consequences of your actions you can make wiser decisions.
