A couple bad examples of processes:
Often, people implement processes because they are aware that <bad thing> can happen and they wish to avoid it. The challenge is that sometimes <bad thing> has a much lower occurrence (occasionally ~0), or cost in a different environment. Meaning that the process they used at another company isn't actually helpful for another company, and may actually cost more than it saves.
Processes can also become obsolete, but are rarely evaluated for that. Again, that means costs without appropriate savings.
Conclusion: Implement processes carefully, and constantly evaluate them for appropriate savings. And don't assume that a process that worked <there> will work <here>, unless you have proof of some sort.
