Have you ever heard the abbreviations CSF, KPI, and SMART?
If you are new to business—or just catching up on things you never quite learned along the way—here is how they are officially defined:
- Critical Success Factor (CSF): According to official ITIL guidance, a CSF identifies something that must be achieved for the initiative to be considered successful. In plain English, it’s what has to be true for you to consider the thing successful.
- Key Performance Indicator (KPI): ITIL defines a KPI as a measurable value used to evaluate progress toward a CSF.
- SMART Objectives: Specific, Measurable, Achievable, Relevant, and Time-bound objectives that provide clear criteria for success.
Here is why they actually matter: CSFs show you what success looks like.
The nice thing about CSFs is that there is not a lot of debate about them upfront. Customers and businesses can usually agree on the big picture without breaking a sweat.
Step 1: The CSF (Using Cats)
To see how this works in the real world, let’s look at a foolproof way to successfully care for a cat.
What has to be true? You:
- Feed it.
- Pet it.
- Play with it.
- Clean its litter box.
Those are your CSFs. Saying “the cat needs to be fed” isn’t going to trigger a two-hour executive meltdown. Everyone in the room nods and agrees.
Step 2: The KPI (Where Things Get Harder)
Now we move on to KPIs, which are a whole lot harder to define.
Sure, feeding the cat is a great CSF, but how often and how much do you feed it? How often do you clean the litter box, and how many litter boxes do you need?
Those metrics must be chosen carefully with the customer of the service or product. We can’t let the customer blindly pick KPIs that are not achievable. You bring your expertise, frameworks, and industry standards to the table. For instance, if you’re working on service management practices like Incident Management, don’t reinvent the wheel—go look up the 14 most common CSFs and bring them to the meeting.
The Rule of Thumb for How Many to Pick
- For a new project, product, or service: Pick about three CSFs. If you pick too many, you will fail and drown in data.
- For KPIs: Pick about three KPIs to tie up to a CSF.
- For mature or complicated activities: They may need more. Mature ones often need at least 5 CSFs, and you might want 5 KPIs tied to a mature CSF.
Don’t be scared to throw these rules out the window. Rules are starting points, not laws of physics. For example, our own incident management process has 12 KPIs, and that’s just how many it needs to actually work. If your situation requires more, use more.
Step 3: SMART (And Why 100% Satisfaction Is a Myth)
Finally, we move on to SMART metrics when the final illusion of perfection—100% customer satisfaction—is officially disproven.
Here is a hard truth: You cannot have 100% customer satisfaction. Even if you were giving away 1 million dollars for free in a suitcase, one person would complain about how heavy it was. You will never make everyone happy, which is why you need structured SMART metrics to keep you grounded.
If your objective reads like a boring corporate yawn, it’s probably missing the mark. If it’s not a word salad tongue twister of clear criteria, it’s likely not a SMART KPI.
And don’t forget the most commonly forgotten part of SMART: time-bound. Saying “we want high satisfaction” means nothing if you don’t add by when.
Stop guessing, start with your CSFs, tie your KPIs to them, make them SMART, and build something that actually succeeds.
