Measure Adoption, Cost, Speed, and Quality

Measure the real cost driver before optimizing, and publish what is not metered.

See the situation

Start with the situation below. Next, we will work through an example together before you try the activity.

The case

The optimization that did nothing

Measure the actual cost drivers and disclose expenses the available meter cannot see.

Assumed driver: Number of calls
Action taken: Called less often
Effect on the bill: Barely measurable
Actual driver: Volume of signal sent per call
How anybody found out: By measuring it

Your task

Adjust the calls and payload sliders. Compare the total bill and decide what evidence must be preserved.

Need a little guidance?

You’re done when: The proposed change targets an observed driver rather than the total cost number.

A cheaper system can become worse if the wrong cost is removed.

Need a reminder? Reopen the worked example

Watch one example first

At 100 records, four calls, ten units per call, 25% retry overhead, and $0.02 per unit, metered cost is $100. Add $400 outside that meter for $500 total in this model.

Why this follows from the evidence

Compare explicit input changes: removing one call saves $25 metered; removing four payload units saves $40. Savings are useful only if required evidence and quality remain adequate.

Case evidence

The optimization that did nothing

Assumed driver: Number of calls
Action taken: Called less often
Effect on the bill: Barely measurable
Actual driver: Volume of signal sent per call
How anybody found out: By measuring it

Somebody pulled the obvious lever and the bill did not move. Identify the real driver, then say what this measurement cannot see.

Check the case below to save your activity result and this chapter’s prepared example plan section. You can inspect that template in the saved plan above; no live records are changed.

Review the case

Change the input and watch the whole bill

For this model: 100 records, four calls per record, ten payload units per call, 25% retry overhead, and $0.02 per unit. The vendor-side $400 is outside this internal meter. These supplied values are illustrative, not current vendor pricing.

Proposed calls per record: 4Baseline: 4 calls per record.Proposed payload units per call: 10Baseline: 10 units per call.

Prepared total

$500.00

One fewer call only

$475.00

Four fewer payload units

$460.00

Your current proposal: $500.00 total ($100.00 metered + $400.00 outside this meter).

Which measured input is the larger lever here?How do you handle the unmetered amount?If lower spend loses required evidence?

Optional: compare alternative reasoning

The case tool above saves your result and completes this activity. These comparisons are extra practice; they do not change your saved plan.

Measure the driver before optimizing it

Compare these alternatives one section at a time. Check a choice to see its consequence; the draft summary below keeps the proposed changes together.

Step 1 of 2

What actually drives the cost?

The volume of per-record signal sent, which had to be measured to find.The number of calls made.The number of records processed.

This is a proposed draft until the chapter check runs. Selecting a choice alone does not complete the chapter.
