To get the results you want from your platform, treat your platform implementation as a change management exercise. If you can't answer the question "Why will this platform improve my CSM's lives?" and your CSMs can't explain why they need the platform, there is a high risk that they will not change and continue to use the incumbent system.
Your team might start from a position of "Why bother?" So you need to be able to explain why this change is an important and worthwhile endeavor. It doesn't matter what you want from a new Customer Success platform - it's not about you. Your job is to help get your Customer Success Managers excited about what will be possible with the new platform. You can do this by working to understand what's in it for them.
For example, if you have ready-made reports, you won't need to nag your team for data and information that should be readily available to you. They will have more time to talk to customers and focus on their work instead of feeling like they always have to keep you up to date. The team might get their valuable time back from you.
To get more mileage out of your change process, use an incremental approach instead of trying to solve all of your problems at once. Each time you roll out something new, you know exactly why you're doing it. This covers rolling out automation, triggers, and a health score - think about it in your team's terms, not yours.
Here are some questions you can ask your CS platform vendor to answer for you:
If they can't authoritatively answer these questions, then you have a huge point of leverage because you can tell your vendor you need answers before you implement their solution.
The value of simplicity and discipline with your Customer Success platform
It's OK to say no to overengineering your platform.
Overengineering is a common mistake people make because they are smart and have found some extra time to tinker with their platform. The reality is that if it works, it works. Don't create a new question or new functionality just because, instead - dig in to understand why you need to do anything new or change anything at all.
At a late-stage company, a Customer Success platform is an entirely different beast.
The platform will take on a different role, solve various problems and be creaking under the weight of the number of different use-cases it supports. For example, it's easy to build a convoluted Customer Health Score because you've run out of dials to turn… but beware! When you start to abstract metrics, blend them and try to share that with your team, it's nearly impossible to rally them behind seven different elements of your shiny new health score. This progression is natural, because as you feel more comfortable with the platform, you'll want to add more.
From experience, we've seen huge lists of equally weighted priorities for platform improvement… and they never get done. It also takes a significant amount of time, effort, and energy to build on top of your platform. You may want to do more integrations with your platform and this will probably require an operations person to help you get this done.
