Severity band: what does it mean for seams on a Seam Map?

A severity band is the fixed weight The Thirteen Seams gives each seam by its junction, not by the company: Root, Critical, High or Medium. Jon Weberg's bands set where to look first; the Seam Map ranking in dollars decides which three close.

  1. 4 bands: Root, Critical, High, Medium.
  2. 1 Root: seam 13, read first.
  3. 4 Critical: 04, 06, 08, 09.
  4. 4 High and 4 Medium.
  5. 0 dollar cut points; dollars pick the 3 to close.

How is a severity band set?

A severity band is set by the junction, not by the company, so every business gets the same four. It is taught, not intuited, and sits in the band column of the Seam Map's Chain Scorecard.

Which seams sit in each severity band?

Seam 13 is Root, seams 04, 06, 08 and 09 are Critical, seams 01, 07, 10 and 12 are High, and seams 02, 03, 05 and 11 are Medium.

BandSeamsWhy it sits there
Root13Keeps every other seam open.
Critical04, 06, 08, 09Largest recoverable value, widest blast radius.
High01, 07, 10, 12Material value, fast, often unmeasured.
Medium02, 03, 05, 11Real, rarely the largest number first.

What does a severity band look like on a real floor?

A Medium seam can still carry the biggest month, which is why the band is only a prior. On AI Acquisition's 22 closer floor the Medium show rate seam moved from 19% to 43% in about a month, with $1,322,312 collected that month, so what is a band telling you?

How is a severity band different from the Seam Map ranking?

The severity band says where to look first; the Seam Map ranking says what to close first.

A band is fixed before any operating lens read; step 3 of close order ranks by dollars.

Questions people ask about severity bands?

Is a severity band a dollar figure?

No. It is a fixed label set by where a seam sits in the chain. Dollars enter at the ranking step.

Why is seam 13 always Root?

Nobody owning the chain keeps every other seam open, so the plan names an owner first.

Who sets the severity band?

The framework, once, for every business; a Seam Architect never re-grades it.

Should I start with a Medium seam?

Rarely. The ranking picks one when the dollars say so.
