Why Big Medical Data Fails ML/AI

May 14, 2025 By Scott

Question: How do you solve a problem or fix something when you’re not even sure exactly what a problem may be; only that you have a vague sense that there is one? This is something for which AI can supposedly help. By dumping in piles of data, you can find insights and patterns. Sounds Great. Until you run into the problem of missing critically meaningful data. For all the stunning benefits Artificial Intelligence (AI) and Machine Learning (ML) tools offer healthcare, we’re collectively missing something. And that something is comprehensive outcome data.

What is outcome data? Quite simply, it’s asking what happened? Not just after a singular healthcare encounter, but longer term. And what about at a population level. Think about your own experiences in the healthcare system. Ideally you’re being reasonably proactive and preventative with good behavior and checkups. (Because, of course, we all eat perfectly and work out just as we should.) Your other experiences were because something went wrong. You got sick or hurt. What happened? You went in, (physically or virtually), you got diagnosed, (ideally properly), and left with some treatment and perhaps a prescription. Then what? Often nothing. In some cases, you will have follow-ups. And your Electronic Health Record (EHR) will be updated accordingly. But much of the time? Not much happens. Maybe that’s fine for you. Who wants to be bothered with a checkup for nothing or yet another survey. Still, is there just an assumption that you got better? If so, was it quickly or after a months long struggle? Maybe you went to another doctor. Maybe you died! (Well, not YOU obviously.)

LLM / Text Vectors for Product Managers

April 18, 2025 By Scott

Intro

Understanding how these things work matters.

Not because you’re going to build the next GPT yourself, but because understanding just enough of how LLMs and vector math work can change how you think about products, teams, and strategy. It can help inspire better solutions, make smarter tradeoffs when AI promises start sounding magical, and maybe even help you call BS when needed. Whatever strategic product decisions you may be making, your implementation team could be internal or perhaps a contract shop. In either case, there’s operations impact and costs that will likely impact your roadmap. If you also have P&L responsibility, you’re going to need to look at the costs here with regard to your business case. And if you don’t, chances are you may be the one who still has to justify the spend to others. As usual in product manager land, even if you’re not the one executing the actual work, you likely need to understand enough about the pieces to know what they can do and what this might cost.

tl;dr

  • LLMs turn text into numbers using math called vector embeddings. We’re going to look at this below.
  • These vectors live in a high-dimensional space, where “distance” equals “semantic similarity.” Again, we’ll look at an example below.
  • Transformers (not the ones from the comics/movies) are the model architectures that makes GPT-style LLMs so powerful.
  • All this lets us build apps that “understand” language enough to generate answers, categorize, summarize, translate, and more.
  • But it’s still math, not magic. And it’s expensive from a lot of perspectives. The question is where do we want to take the expense hit(s) and for what level of benefit.

Product Management Analytics Purpose & Goals

June 10, 2024 By Scott

At a strategic level, Product Analytics isn’t just about the “How.” That’s important, but is more tactical. It’s more about the “What” and the “Why.” Basically, are your outcomes driving toward your goals.

We are overwhelmed by information, not because there is too much, but because we haven’t learned how to tame it. Information lies stagnant in rapidly expanding pools as our ability to collect and warehouse it increases, but our ability to make sense of and communicate it remains inert, largely without notice.

Stephen Few, Data Visualization Expert

The What and the Why

What are you trying to do? Probably running and growing your business; within guardrails including internal financial and external regulatory concerns. Most analytics are historical lagging indicators. You may have items you consider leading indicators; a sales pipeline or scheduling system, possibly equipment failure estimations, etc. And you may be using predictive models including AI tools. But mostly, your performance reports will be historical. And why study history? Typically it’s to try to predict or change the future.

So What are you trying to do?

Customer Journey Map Template

March 28, 2022 By Scott

While working on a new component of a project, I had occasion to build out a Customer Journey Map. Even though I’ve done this several times before, I’d kind of just cobbled together a map using Omnigraffle or LucidChart or some other drawing program. But this time I had to do a few of them and wanted a more common format template. What I found was a ton of examples in image search, but very few usable editable templates. (There were a few behind some paywalls and seemingly sketchy download requirements, but not much else.)

Website Speed is a Feature

June 20, 2017 By Scott

Speed Dial

Your login functionality is a feature. Your social sharing buttons are

features. Your core product offering itself has who-knows-how-many features. But what about your website’s speed? Given that research has shown slow website speed, (whatever slow might mean to some users), can hurt you in terms of abandonment and lost sales when there’s any sales involved, shouldn’t speed be considered a feature? That is, maybe website load time shouldn’t be just a “tech thing” that kind of gets done as a matter of course. Rather, it should be a core measurement given that it’s demonstrably a driver of other Key Performance Indicators. (KPIs.)

How bad is the problem?

Following are a couple versions of a chat about Speed I put together for a Udemy.com course I built for Digital Product Management. The ideas are so important though, I’ve extracted these as free segments because the more people that spread this word the better.

SaaSalytics – Some SaaS Services Lacking in Tracking

February 4, 2017 By Scott

SaaS (Software as a Service), and its variants, PaaS (Platform as a Service), IaaS (Infrastructure as a Service), DaaS (Data as a Service or Desktop as a Service), and more… are all on a tear right now. In the classic Buy vs. Build argument, we’ve now got more reasons than ever before to hire out for more and more components of our businesses. Unfortunately, these still nascent services may often lack core analytics capabilities or the ability to provide hooks or tags to insert your own collection capabilities.

Quick Review on Why to Build Your Own Code

There remain some key reasons for continuing to build your own technology, even when there’s some great aaS out there for you. Among them… [Read more…]

Relationship Cartography – It’s Not Just about the Social Graph Alone

February 17, 2016 By Scott

SocialGraph-1Let’s talk about Relationship Cartography in general. What is it? Well, I’m not 100% sure yet as I just made it up. The thing is, I’ve been looking at so-called Social Graphs, Commercial Graphs, Economic Graphs and more lately. And I’m struggling to find a unifying theme for these various sub-types of relationship visualizations. Maybe I’ll go into these various types in detail later on in a follow on post Types of Relationship Graphs, but for now I’d like to just blather a bit about graphs in general. You’ve probably heard of them. And maybe done a little research. Still, it’s sometimes useful to take a high level conceptual view of things to understand the parts a little better.

Excel Spreadsheet Google Analytics Tracking Scheme Generator

May 19, 2014 By Scott

Yes, it’s a long title for an Excel Spreadsheet used to create utm tracking scheme variables for Google Analytics. I’m just doing a tiny bit of keyword stuffing here so the page gets found and people can use the spreadsheet I made if they like.

The Poor Site’s Tracking Method!

The big web sites may be able to afford the high end analytics solutions, but most sites starting out are stuck with love using Google Analytics. It’s an extremely capable product, especially in that it’s free. There’s a variety of other beacon / JavaScript based solutions out there, but I’ve found even those using these tools typically also have Google. In many cases, tracking codes are done for you. For example, if you’re using adwords and have hooked in your accounts properly the gclid variable should show up free, no effort on your part. And over time, Google has added other referrals such as social referrals to help. Moreover, increasingly third parties, (such as sharing tools like AddThis or ShareThis), also make it easier on you. Still, there are times when you just have to make your own. For those times I’ve found a sheet like the one attached below to be useful. Admittedly, it can be a pain to create your original schema and maintain things like this. But it’s not all that bad and once you have things set up, things go pretty quickly.
