Three of the seven worksheets from the book, to fill in in your browser: the trigger check, zone and pace, and the coupling measurement. Print the result or save it as a file. The full set is in Part Five of the book; the tools page lists where each tool is built.
Worksheet 2 · The trigger check
Does this use need an explicit rule at all?
Time: five minutes per item. Take one process in which a system plays a part and go through the five questions.
Five questions. One yes is enough.
Worksheet 3 · Zone and pace
How strictly is a process handled, and at what pace?
Time: ten minutes per item plus an hour to review them all. Two columns on one sheet, because one alone does not hold.
The pace a process actually runs at matters most. Write down how it runs, whatever the plan says.
Worksheet 4 · The coupling measurement
What actually arrives at the review desk?
Time: two hours from system data, a day with a tally sheet over two weeks. Pick one desk. Not all of them.
Volume and time
How many items reach the desk in the time set aside for them, and how long does an item sit there?
The book works with six. Enter what is actually free for review at this desk.
Change rate
In how many items did the review change the result last quarter? Count changed results. That a review took place does not count here.
All three worksheets come from Part Five of Cheap to Make, Costly to Check. The book has four more, each with the same running example.
They are thinking tools, not legal review. Where one of them touches a legal question, it stops at noting that there is one. The answer comes from elsewhere.
