Pensieve Labs
The operating system for hospitals
DIS-GL-036
v1.0.0 | 01 August 2026
DIS-GL-036 v1.0.0, Last Modified On 01 August 2026, Tier: Public
| DM-1 | DM-2 | DM-3 | DM-4 |
|---|---|---|---|
| Sections 2 to 5 | Sections 2 to 5 | Sections 2 to 5 plus Section 6 | Sections 2 to 5 plus Section 7 |
Sections 2 to 5 describe what a hospital needs on its own floor in every deployment model. Sections 6
and 7 add what the hospital additionally owns in DM-3 and DM-4.
This is published so that the hospital's own procurement never sets the go-live date.
The single most common cause of a slipped hospital go-live is not software. It is that somebody counted the workstations in week three, discovered a shortfall, and started a procurement cycle that takes between five days and three weeks. That delay is entirely avoidable by publishing the number before the proposal is accepted, so that procurement runs in parallel with everything else rather than after it.
Issue this document with the proposal, alongside the Infrastructure Readiness Checklist
(CHK-GL-036), not after signature.
Figures below are the minimum for a wave-1 go-live at a 150 to 200 bed multi-specialty hospital, and are
re-derived per deal against the hospital's own counter count in FRM-GL-004 and FRM-GL-116.
| Column | Meaning |
|---|---|
| Minimum for wave 1 | Below this, a department must be removed from wave 1 in writing. It is not compensated for by hoping the queue will be short |
| Comfortable | The count at which the hospital is not managing a shortage on go-live morning |
There is no third column called "we will manage". The minimum is a floor, not a target.
| Location | Minimum for wave 1 | Comfortable |
|---|---|---|
| Registration / front office counters | 2 | 4 |
| Billing / cash counters | 2 | 4 |
| Pharmacy counters | 1 | 2 |
| Laboratory (reception and reporting) | 2 | 3 |
| Radiology: reception and reporting | 1 | 2 |
| Nursing stations | 1 per floor | 1 per ward |
| Insurance / payer desk | 1 | 2 |
| Accounts | 1 | 2 |
| Bill printers | 1 per billing counter | 1 per billing counter |
| Sticker / label printers | 1 in laboratory, 1 in pharmacy | + 1 at registration |
| Barcode scanners | 1 in laboratory, 1 in pharmacy | 1 per counter |
Workstation specification. Any machine that runs a current mainstream browser at 1366×768 or better is
sufficient. Pensieve is browser-delivered and imposes no client installation, no fixed operating
system and no licence per seat.
| Item | Requirement |
|---|---|
| Browser | A current version of a mainstream evergreen browser, auto-update suppressed during the cutover window |
| Display | 1366×768 minimum; 1920×1080 at billing and reporting counters |
| Input | Keyboard and mouse. Touch-only devices are not a wave-1 counter |
| Printers | Any network or USB printer with a current driver. Thermal label printers at laboratory and pharmacy |
| Scanners | Any USB or Bluetooth 1D/2D barcode scanner in keyboard-wedge mode |
| Card terminal | The hospital's existing terminal. Pensieve Labs does not supply or certify payment hardware |
| # | Requirement | Minimum | Why this number |
|---|---|---|---|
| N1 | Wired LAN drop at every wave-1 counter | 1 per counter, tested live at the counter | A drop that exists on a drawing is not a drop |
| N2 | Internet bandwidth | 10 Mbps symmetric contended, measured at the OPD peak hour | The platform is bandwidth-light; peak-hour contention, not headline speed, is what fails |
| N3 | Second connectivity path | A second ISP or a mobile failover. Where absent, recorded as an accepted risk signed by the owner | Single-path connectivity is the most common DM-1/DM-2 availability risk and it belongs to the hospital |
| N4 | Static IP | Not required | Stated because hospitals are frequently told otherwise |
| N5 | Firewall | Outbound HTTPS to the platform endpoints, tested, not assumed | An untested firewall rule is discovered at 08:00 on go-live day |
| N6 | Wi-Fi | Only where clinicians work at the bedside. Dead zones mapped, not assumed | |
| N7 | Switching | Managed or unmanaged both acceptable. Inventory recorded |
| # | Requirement | Minimum |
|---|---|---|
| P1 | UPS at every wave-1 counter | Measured runtime carrying the workstation and its printer together, not the rating-plate figure |
| P2 | UPS runtime | 15 minutes measured, at every counter |
| P3 | Generator | Switchover time measured, and confirmed to cover the counters, not only theatres and critical care |
Power is the item most often assumed and least often measured. A rating plate is not evidence; a stopwatch is.
Nothing here is a refusal. It is a sequencing rule.
Pensieve Labs will not certify go-live readiness for a department that is below the wave-1 minimum.
Certifying it produces a queue on go-live morning, and the hospital remembers the queue, not the
explanation.
