Agentic PDLC 2 · Ranking, rungs, and the cost of delay

[akash-coded]

Ranking and rungs

Exercise 2 · 10 minutes

Five tasks. Two need arithmetic, three need a letter.

Task 1 · Complete the table

Cost of delay is the three value columns added. WSJF is that total divided by job size. Rank 1 goes first.

Option	Value	Time	Risk	Cost of delay	Job size	WSJF	Rank
Alert on offload	8	8	5		3
Assisted re-route ranking	8	5	8		8
Autonomous resolution agent	13	5	3		13
Booking screen redesign	3	2	2		5

One of these has the highest value score and does not go first. Note which, and why the denominator did that.

Task 2 · Two items, one team

	Cost of delay	Duration
A Alert on offload	$19,400 per week	3 weeks
B Assisted re-route ranking	$24,000 per week	8 weeks

Which order do you run, and what does the other order cost you?

(a) B then A, and the wrong order costs $83,200
(b) A then B, and the wrong order costs $47,200
(c) A then B, and the wrong order costs $83,200
(d) B then A, and the wrong order costs $124,800

Task 3 · Match the feature to its rung

The ladder, from the top rung down:

Rung	Who decides the next step	Cost per use	How it fails
S	the system chooses its own steps and tools	per step, variable	quietly, and acts on the mistake
T	fixed path, model judges one step	per call	quietly, one answer at a time
U	you, in a fixed sequence of steps	about zero	loudly and visibly
V	you, in a single condition	about zero	loudly and visibly

Write S, T, U or V against each feature. One feature does not sit on the ladder at all.

#	Feature	Rung
1	Send an alert when a shipment status changes to offloaded
2	Rank the three best re-route options for an ops agent to choose from
3	Resolve the exception end to end, choosing between rebook, split, re-route or claim
4	Run a fixed six-step rebooking sequence whenever the next flight has capacity
5	Store the exception history in the audit log

Task 4 · Read the curve

Cost per exception against the share resolved automatically. Doing nothing costs $14.00.

Point	Coverage	Cost per exception
W	30%	$10.77
X	50%	$9.89
Y	70%	$11.75
Z	90%	$18.35

4.1 Which point would you ship?

4.2 One point costs more than automating nothing at all. Which?

4.3 The bar is 94 percent and the model reaches 85 percent. Which move lowers the bar itself?

(a) Retrain the model on more historical exceptions
(b) Raise the confidence threshold so fewer cases are attempted automatically
(c) Hold the action for ten minutes so a person can stop it
(d) Allow the agent more steps per case

Task 5 · One of these is false

(a) The accuracy bar rises when the cost of being wrong rises
(b) Raising coverage always raises the saving, because more cases are automated
(c) A wrong automatic answer costs the human handling anyway, plus the damage
(d) The token bill is a small share of what an agentic path replaces
