GlossaryKind of term: BlakeConfirm and correct
What does confirm and correct mean in Blake?
In Blake, confirm and correct is a person's decision on a proposal: accept it or change it, recorded with name and time.
The yardstick is the drawing itself: you confirm when the value matches it and correct the value when it differs. The step resembles signing off a drawing at release, but per value rather than per drawing.
How does ‘confirm and correct’ work in practice?
Say the proposal gives ⌀12 H7 while section A-A shows ⌀12 H8. That difference can change the choice between reaming, boring or precision drilling, and with it the gauge and the time. Because every decision is recorded with a name and a time, you can later trace who established a requirement, for instance after a complaint or on a repeat order. If two colleagues read the same drawing differently, the history shows where.
What is ‘confirm and correct’ often confused with?
Confirm and correct is not the same as human-in-the-loop: that is the principle that a proposal only counts after a human decision; confirm and correct is the decision itself. Nor is it post-calculation, where you compare estimated with actual times and costs; here you establish what the drawing asks for.
How do you see ‘confirm and correct’ in Blake?
The proposals sit with the part in the request and you decide per value. On a drawing value a note is optional. A correction to an estimate line needs a reason, and the previous value is kept. More on requests.
Frequently asked questions
Do I have to give a reason for a correction?
On an estimate line, yes: you do not change a time, rate or quantity without a reason, and the previous value is kept. On a drawing value, name and time are recorded and a note is optional.
Can a colleague reverse my decision?
A colleague can correct the value again. The history shows who changed what and when, so your earlier decision can still be traced.
Why sign off per value rather than per drawing?
A drawing can hold dozens of requirements, and each can change the route or the price. Signing off per value shows which requirement has been checked and which is still an open proposal.
