Does It Actually Work?
Theory of change, logic models, and how to measure nonprofit impact honestly
A program is a hypothesis. You are claiming that if you do a specific thing, a specific change follows — and a claim can be wrong.

What it is
Most programs are never tested, and the reason is not laziness. It is that testing feels like doubt, and doubt feels disloyal to people you are trying to help. So the design stays in one person’s judgement, the eligibility line gets drawn by whoever answers the phone, and the dose drifts down until what is being delivered is a gesture.
This volume is the correction, and it is practical rather than academic. Theory of change without the jargon, on one page, in plain words. Dosage, and the threshold below which you are not really running a program. Fidelity, and which parts of yours are load-bearing. The pilot, which is a question with an end date rather than a small version of the thing. Intake, safeguarding, participant voice, and quality on the weeks nobody is watching.
Then measurement you can actually do with volunteers and a spreadsheet, and the harder half — saying what you found without overclaiming. There is a sentence in Chapter Eighteen that is defensible and a sentence that is not, and they are one word apart.
An unexamined program is not a humble program. It is an experiment being run on people without anyone admitting it is an experiment. Book III · Does It Actually Work?
What this volume assumes
That you are running something, or about to. It does not re-teach formation — that is Book One.
Every chapter
25 chapters, and what each one does.
Every one of them, with the line it opens on. If a chapter is no use to you, that line tells you before you have spent ten minutes finding out.
- 01
A Program Is a Hypothesis
You are claiming that if you do a specific thing, a specific change follows. That is a claim, and it can be wrong.
- 02
Theory of Change Without the Jargon
One page, five columns, plain words. If it needs a key, it is not doing its job.
- 03
Who You Serve, and Who You Turn Away
Every program has an eligibility boundary. Most have never written it down, which means it is being drawn by whoever answers the phone.
- 04
Dosage
How much, how often, for how long — and the threshold below which you are delivering a gesture.
- 05
Fidelity, and the Right Amount of Rigidity
Some parts of your program are load-bearing. Most are not. Knowing which is which is the whole skill.
- 06
Borrow Before You Invent
Somebody has probably already tested this, and they will give you the answer for free.
- 07
The Pilot
A pilot is not a small version of your program. It is a question with an end date.
- 08
Intake and the First Contact
The first ten minutes teach a person what kind of organization you are, and they are usually designed by nobody.
- 09
Safeguarding and Duty of Care
The chapter you hope never becomes relevant, written on the assumption that it will.
- 10
The Session Itself
The unit of your program is not the year. It is the hour, repeated.
- 11
Staffing a Program
The question is not how many people. It is which parts of the work require which kind of person.
- 12
Training and Supervision
Training is what you say once. Supervision is what makes it true a year later.
- 13
Records, Notes, and Data a Volunteer Can Use
If it takes more than two minutes, it will not happen. If it is not written down, it did not happen.
- 14
Participant Voice
The people receiving your program know things about it that you cannot find out any other way.
- 15
Quality When Nobody Is Watching
Quality is not a standard you meet. It is a set of small habits that survive a bad week.
- 16
Outputs, Outcomes, and the Difference That Matters
You served two hundred people. That is not a result. It is a receipt.
- 17
Measuring Without a Researcher
You will not run a trial. You can still find out.
- 18
Honest Claims
The difference between what happened and what you caused is where most nonprofit communication quietly breaks.
- 19
What the Data Will Not Tell You
Measure what you can. Then be honest that the most important thing may not be on the list.
- 20
Reporting
Three audiences, three documents, one set of facts.
- 21
Improving
One change a year, chosen deliberately, beats twenty changes a year chosen by whoever spoke last.
- 22
Scaling Without Breaking It
Growth is the most common way a working program stops working.
- 23
Referral Networks
You are one service in somebody's life. Behaving as though you are the only one is the most common design error in the sector.
- 24
When a Program Should End
The hardest sentence in this book: it worked, and it is time to stop.
- 25
The First Cohort
A plan for designing, launching, and learning from your first twelve people.

It is usually better to serve fewer people at full dose than more people at half dose.

Where this one stops
That you are running something, or about to. It does not re-teach formation — that is Book One.
Nothing here is repeated in another volume. When the answer lives in a different book you get a chapter number, not four pages you have already read.

The whole Library lands at once. Attendance is not a result. Neither is satisfaction. How to design something real, measure it without a researcher, and say it out loud.
