Perspectives & Post-its

Same file. Different lenses. Different post-its.

A tag says what the file is about. A perspective says who is reading and what they see.

The same evidence means different things to different roles in the same office. A vendor invoice is a tax document and a contract signal and a relationship cue. All at once. Five lenses, one PDF.

L3 — Many lenses on the same readable file

LAYER 3 · POST-ITS

One file. Many readers. One short post-it from each.

The readable .md (L1) sits in the library. Each perspective takes a turn reading it through its own lens, and writes one short post-it — one observation, one row, citing the source.

CA · finance”GST input ₹4,500 eligible. File against Q2 books. Confirm vendor’s GSTIN matches.”

Lawyer · contract”Terms say payment in 30 days. No late-fee clause. Push for indemnity language next time.”

One file arrives

A vendor invoice. PDF. Same bytes.

Founder · business”Third invoice from this vendor this quarter. They’re becoming critical — start a backup.”

Coach · relationship”Friendly note in cover email. Worth a thank-you reply — they’re going beyond invoice-and-go.”

Architect · system”Vendor offers an API now. Could plumb directly into the books. Worth a half-day spike.”

Five readings, one PDF. + your perspectives.

Your office defines its own lenses

The five above — finance · legal · business · relationship · technology — are common across most offices. Every business adds the lenses that matter to its work.

Solid pills are the common five. Dashed pills are domain lenses an office adds. A shipping company adds Master, Chief Engineer, Class Surveyor, DPA. A clinic adds Doctor, Nurse, Compliance. A law firm adds Senior Partner, Counsel. Your office, your lenses.

What’s in a post-it

A post-it is small. One observation. One row in the index. A few seconds to read.

Short

One observation per post-it. One to three sentences. Scannable.

Lensed

Stamped with the perspective that wrote it. Filterable by lens later.

Sourced

Carries the link back to the file it came from. Always.

Anchored

Tagged to the casefile it belongs to — engagement, vessel, person, project.

Importance

A score from low to critical. Drives what gets recalled later.

Dated

When the post-it was written and when the event happened — two timestamps.

Why lenses beat tags

A tag tells you what the file is about. It is a label. It does not tell you what to do.

A perspective tells you who is looking, and what they see. Same evidence, different meaning, different actions. A year later, when the office asks “how is tax compliance tracking?” — the CA lens has already done the thinking. “How is the relationship with this vendor?” — the Coach lens has too.

Cross-cutting recall by lens is what tags cannot do.
