BLAP & PSMC: McGrinsey's business-core sketch
BLAP and PSMC were internal labels on a McGrinsey poster for the business core. Artefact, not an industry framework.
BLAP & PSMC was an internal McGrinsey sketch for the business core. Not an industry standard, not a certified framework, not a textbook model. A working drawing that packed core and operations into two acronyms and went on the wall.
In 2022 the magazine stub shipped with exactly two words under it: Business Core. The image stayed. The text was missing for a long time. This is the glue, without inventing a framework history around it.
What BLAP and PSMC are here
On the sheet the two labels sit as axes of the core. The graphic sorts what has to run in the shop so offer, operations and effect do not drift apart. For the public, that is all the letters carry: house shorthand from an early McGrinsey phase, kept as a poster, not sold as a method.
If you know internal sketches, you know the type. A sheet that appears in a workshop because someone wants the parts of the business on one page. Some sheets vanish. Some stay as a reminder of how the team saw the core then.
Why a sheet like this still helps
A business core on a poster forces cuts. You cannot draw twelve strategies large at once. You have to say what is centre and what is edge. BLAP & PSMC was that exercise for McGrinsey: name the core, drop the rest, save the image.
As a magazine piece it works as an artefact. As an operating manual for other firms it does not. If you build your own core poster, use your own terms. Do not copy our letters. Copy the pressure: one page, two poles, everything else down.
Business core, made visible
Business core here means: what has to stand so the rest makes sense. Offer, operations, cash flow, effect. The BLAP & PSMC sketch was McGrinsey’s attempt at the time to pull that onto one sheet. Later tools and texts in the house use other names. The poster stays as a trace from the early phase.
If you read the image today, read it as a snapshot. Not as a promise that the same shorthand is still the current operating language.
