Unified vs Modular Senior Care Software — Decision Hub
The unified-vs-modular question is not one decision — it is four. What does fragmentation actually cost? Why did senior housing & care end up this way? What is my specific TCO penalty? How would I decide between vendors? Each question has a different audience and a different artifact. Smashing all four into a single page produces a page no one reads cover-to-cover and an answer no one can cite.
Why this is a hub, not a page
The unified-vs-modular question is not one decision — it is four. What does fragmentation actually cost? Why did senior housing & care end up this way? What is my specific TCO penalty? How would I decide between vendors? Each question has a different audience and a different artifact. Smashing all four into a single page produces a page no one reads cover-to-cover and an answer no one can cite.
This hub keeps each artifact at full depth and lets a CFO, a CIO, an operator, and an engineer each land on the surface that answers their question. They converge on the same conclusion — but they do not have to read the same page to get there.
On this page
The canonical content spine for the unified-vs-modular decision in senior housing & care: the Industry Findings on what fragmentation costs, the history that explains how we got here, the interactive TCO calculator, and the architecture spec that makes unified possible.
Key points
- A 10-item teardown of what an 8–12 vendor stack actually costs. Anonymized, third-party feel. PDF + long-form page.
- Historical essay on PCC, MatrixCare, Yardi, and Eldermark origins — why no incumbent started from the operator data model.
- Enter your real vendor list and headcount. Get the annualized penalty vs a unified senior care OS.
- The definitive 2026 buyer comparison — TCO, integration risk, governance, implementation speed.
- The canonical data dictionary, event model, granular role-based access matrix, and tenant isolation pattern that make unified possible.
- It is the single canonical place for senior housing & care operators to evaluate the unified-vs-modular decision: the underlying cost (Fragmentation Tax), the history that produced it (Why best-of-breed), an interactive TCO calculator, the buyer decision framework, and the architecture that makes unified possible.
- If you are early in the question, read The Fragmentation Tax first. If you are sizing the cost for a board memo, run the Unified vs Modular TCO Calculator. If you want the architecture proof, read the Operating System Spec. If you are choosing between vendors, use the Decision Framework.
- It is Industry Findings — anonymized synthesis of operator interviews, contract review, and time-and-motion sampling across operators of 5+ communities. Figures are ranges, not point estimates, intended for planning rather than financial modeling.
