Most reasonable should be to gather the current usage of resources and also estimate a surplus buffer for future needs so you will have some stable planing for the close future.
You or your management might know best what additional workload might come in the future. Careful planning will also decrease the needs of changes to the infrastructure and resources.
There can always be something happening nobody has seen before hand. CoD (Capacity on Demand) is a feature that comes with p-Series and POWER machines. It means that you have for example a box that is built to it's maximum of 32 CPUs but you actually pay and use for example only 20 of them. If there is dire need because of some failover event happened or a critical workload peak rises up, you can activate for a somewhat low fee those CPU reserves until this critical situation is bypassed. Same is available for memory etc. If you later decide you need more CPU or RAM constantly, you can buy them of course and they are already in the machine. They will only have to be activated.

Here is a short IBM Red Paper that explains CoD:

You also have to keep in mind, that sloppy code will not always be speeded up by pure hardware power. There might be some point where there is not much speedup seen, no matter what you activate.
