> That’s not debugging, that’s pattern-matching. That’s … eyeball racing. Um...yes. And that is a very good thing . Because if there is anything the human brain is good at, it's pattern matching. Especially on visual data. It's an extremely quick and efficient way to find out where to start the detailed debugging. And there is a lot of value in that.

the brain is also good at fooling itself

I spent the past four years working as a data scientist for a healthcare company on population health initiatives, and started building out a body of research around how to engage clinicians using data (among other things, through dashboards). That's a bit different than the article, but one of my key learnings was that dashboards are often incredibly ineffective and only promulgated by well-intentioned engineers, ba…

Are you me? I also built out a body of research in a healthcare company about how to engage clinicians using data, that stopped us from making some mistakes until we got acquired. No doctor (or chief of staff, or chief medical officer, or anyone besides an actual data analyst) will slice and dice their data. Doctors won't even listen to a non-peer clinician discuss data with them, let alone their administrators. In m…

Can you provide concrete examples of data that would be shown in such dashboards? I'm having trouble visualizing it.

Do you think there's an alternate approach to showing data that would be effective? I can definitely buy the idea that showing a bunch of fancy charts doesn't help most medical professionals, but I don't like the idea of giving up on trying to surface more data. Or is that what you're referring to as "non-dashboard approaches"?

Dashboards are invaluable. Humans can intake a lot of data from images and there is not better way to grok data than a graph. We've spent a lot of time building Grafana dashboards and they've been extremely helpful with debugging. It doesn't solve all problems but it certainly helps narrow down where to look. Sure, we still look at log files, use htop and a lot of other tools, but our first stop is always Grafana. I…

A dashboard in a car gives you largely active feedback to help you drive. Mechanics' diagnostic tools give them a deep dive into information about repairing the vehicle, not limited to real time or to just driving activity. Those two things are very different. I don't think a debugging "dashboard" is a dashboard. That conflates two very different ideas. We need a different name for that.

What about the "check engine" light or the "low oil" light? Both are debugging indicators about the health of your engine.

But snark aside, I do agree with your about the intent of a dashboard. I've always told people dashboards are there to give you historical and real-time info about the performance and rates of your systems. It doesn't show you exactly what's wrong, but it is very helpful in showing where to start looking.

There’s so many vanity metrics in business related data science that I suspect when the visualization gets blamed instead of what is being visualized.

I have trouble trusting any dashboard if it doesn't have the equivalent of a "view source" button that lets me see what data sources were used for it and how they were manipulated.

Sadly dashboard systems that encourage this are extremely rare.

I don't think dashboards help with debugging at all, and they shouldn't be designed with that goal in mind.

Dashboards tell you that a problem exists. Just demonstrating that SOMETHING is broken means the dashboard has accomplished it's task in full. The engineer's job is then to fix it.

Earlier quoted context omitted.

> A dashboard is a way to view multiple disparate metrics in a single place. This is technically correct but doesn't approach anywhere near the criticisms the article has. The deeper questions are: how did those metrics come to be collected, and why? What happened that resulted in those particular metrics being aggregated and displayed they way they are? What questions were being asked at the time the dashboards were…

That's why good dashboards come with Title, subtitle, legend, the X and Y axis, and units. Count of packets denied from source IP, source port, last 4 hours. Average number of requests forwarded to proxy farm, distributed by server, last 7 days vs. same time last month. Who called 2049, last 24 hours.

Yeah, but why?

You are talking tactics, not strategy. What are the underlying goals?

I wrote a longer response to another comment with examples of some of the experiments and learnings. But, yes, I think there are effective alternatives, but I think it starts with being really clear on what your success measures are. Do you want to maximize patient outcomes? Do you want providers to feel engaged (or, perhaps, actually engage) with data? Do you want to minimize provider burnout? I was always surprised by how few clinical and tech leaders could actually articulate what the goals were-- it'd often just be "we need providers to have more data!", which I suspect isn't actually what your goal is.

The tldr was that telling providers directly what you want, generally in an emailed newsfeed-style format was the most effective at improving actual outcomes. No slicing and dicing. No graphs. No comparisons. Just "hey, look at these 6 uncontrolled hypertensive patients, and follow-up with any that need follow-up."

Also, to caveat: I'm talking about how to engage the worker-bee providers. Not clinical leadership. Not the quality team. Not the data science/analyst team. Providers who are super busy with patient care, but also expected to manage patients between visits. Basically every experiment we ran favored the most direct, no frills, least effort approach to look at data. Which, coincidentally, was the exact opposite of what the engineering teams wanted to build :-/
